PIC16F5X 1.0 GENERAL DESCRIPTION 1.1 The PIC16F5X from Microchip Technology is a family of low-cost, high-performance, 8-bit, fully static, Flashbased CMOS microcontrollers. It employs a RISC architecture with only 33 single-word/single-cycle instructions. All instructions are single cycle except for program branches which take two cycles. The PIC16F5X delivers performance an order of magnitude higher than its competitors in the same price category.
PIC16F5X NOTES: DS41213C-page 6 2004 Microchip Technology Inc.
PIC16F5X 2.0 ARCHITECTURAL OVERVIEW The high performance of the PIC16F5X family can be attributed to a number of architectural features commonly found in RISC microprocessors. To begin with, the PIC16F5X uses a Harvard architecture in which program and data are accessed on separate buses. This improves bandwidth over traditional von Neumann architecture where program and data are fetched on the same bus.

PIC16F5X 2.1 Clocking Scheme/Instruction Cycle 2.2 Instruction Flow/Pipelining An instruction cycle consists of four Q cycles (Q1, Q2, Q3 and Q4). The instruction fetch and execute are pipelined such that fetch takes one instruction cycle, while decode and execute takes another instruction cycle. However, due to the pipelining, each instruction effectively executes in one cycle. If an instruction causes the Program Counter to change (e.g.
PIC16F5X 3.0 MEMORY ORGANIZATION PIC16F5X memory is organized into program memory and data memory. For the PIC16F57 and PIC16F59, which have more than 512 words of program memory, a paging scheme is used. Program memory pages are accessed using one or two Status register bits. For the PIC16F57 and PIC16F59, which have a data memory register file of more than 32 registers, a banking scheme is used. Data memory banks are accessed using the File Selection Register (FSR).
PIC16F5X 3.2 3.2.1 Data Memory Organization Data memory is composed of registers or bytes of RAM. Therefore, data memory for a device is specified by its register file. The register file is divided into two functional groups: Special Function Registers (SFR) and General Purpose Registers (GPR). GENERAL PURPOSE REGISTER FILE The register file is accessed either directly or indirectly through the File Select Register (FSR). The FSR register is described in Section 3.
PIC16F5X FIGURE 3-5: PIC16F59 REGISTER FILE MAP FSR<7:5> 000 001 010 011 100 101 110 111 File Address 00h INDF(1) 01h TMR0 02h PCL 03h STATUS 04h FSR 05h PORTA 06h PORTB 07h PORTC 08h PORTD 09h PORTE 20h 40h 60h 80h A0h C0h E0h Addresses map back to addresses in Bank 0.
PIC16F5X 3.2.2 SPECIAL FUNCTION REGISTERS The Special Function Registers (SFR) are registers used by the CPU and peripheral functions to control the operation of the device (Table 3-1). The Special Function Registers can be classified into two sets. The Special Function Registers associated with the “core” functions are described in this section. Those related to the operation of the peripheral features are described in the section for each peripheral feature.
PIC16F5X 3.3 Status Register This register contains the arithmetic status of the ALU, the Reset status and the page preselect bits for program memories larger than 512 words. The Status register can be the destination for any instruction, as with any other register. If the Status register is the destination for an instruction that affects the Z, DC or C bits, then the write to these three bits is disabled. These bits are set or cleared according to the device logic.
PIC16F5X 3.4 Option Register The Option register is a 6-bit wide, write-only register which contains various control bits to configure the Timer0/WDT prescaler and Timer0. By executing the OPTION instruction, the contents of the W register will be transferred to the Option register. A Reset sets the Option<5:0> bits.
PIC16F5X 3.5 FIGURE 3-7: Program Counter As a program instruction is executed, the Program Counter (PC) will contain the address of the next program instruction to be executed. The PC value is increased by one, every instruction cycle, unless an instruction changes the PC. LOADING OF PC BRANCH INSTRUCTIONS – PIC16F57 AND PIC16F59 GOTO Instruction 10 9 8 7 PCL For a GOTO instruction, bits 8:0 of the PC are provided by the GOTO instruction word.
PIC16F5X 3.6 Stack The PIC16F54 device has a 9-bit wide, two-level hardware PUSH/POP stack. The PIC16F57 and PIC16F59 devices have an 11-bit wide, two-level hardware PUSH/POP stack. A CALL instruction will PUSH the current value of stack 1 into stack 2 and then PUSH the current program counter value, incremented by one, into stack level 1. If more than two sequential CALL’s are executed, only the most recent two return addresses are stored.
PIC16F5X 4.0 OSCILLATOR CONFIGURATIONS 4.1 Oscillator Types TABLE 4-1: Osc Type The PIC16F5X devices can be operated in four different oscillator modes. The user can program two configuration bits (FOSC1:FOSC0) to select one of these four modes: • • • • LP: XT: HS: RC: Low-power Crystal Crystal/Resonator High-speed Crystal/Resonator Resistor/Capacitor 4.
PIC16F5X 4.3 External Crystal Oscillator Circuit FIGURE 4-4: Either a pre-packaged oscillator or a simple oscillator circuit with TTL gates can be used as an external crystal oscillator circuit. Pre-packaged oscillators provide a wide operating range and better stability. A well designed crystal oscillator will provide good performance with TTL gates. Two types of crystal oscillator circuits can be used: one with parallel resonance or one with series resonance.
PIC16F5X 5.0 RESET The TO and PD bits (Status <4:3>) are set or cleared depending on the different Reset conditions (Table 5-1). These bits may be used to determine the nature of the Reset. The PIC16F5X devices may be reset in one of the following ways: • • • • • Power-on Reset (POR) MCLR Reset (normal operation) MCLR Wake-up Reset (from Sleep) WDT Reset (normal operation) WDT Wake-up Reset (from Sleep) Table 5-3 lists a full description of Reset states of all registers.

PIC16F5X 5.1 Power-on Reset (POR) The PIC16F5X family of devices incorporate on-chip Power-on Reset (POR) circuitry which provides an internal chip Reset for most power-up situations. To use this feature, the user merely ties the MCLR/VPP pin to VDD. A simplified block diagram of the on-chip Power-on Reset circuit is shown in Figure 5-1. The Power-on Reset circuit and the Device Reset Timer (Section 5.2) circuit are closely related. On power-up, the Reset latch is set and the DRT is reset.

PIC16F5X 5.2 Device Reset Timer (DRT) FIGURE 5-7: The Device Reset Timer (DRT) provides an 18 ms nominal time-out on Reset regardless of the oscillator mode used. The DRT operates on an internal RC oscillator. The processor is kept in Reset as long as the DRT is active. The DRT delay allows VDD to rise above VDD min. and for the chosen oscillator to stabilize. Oscillator circuits, based on crystals or ceramic resonators, require a certain time after power-up to establish a stable oscillation.

PIC16F5X 6.0 I/O PORTS As with any other register, the I/O registers can be written and read under program control. However, read instructions (e.g., MOVF PORTB, W) always read the I/O pins independent of the pin’s Input/Output modes. On Reset, all I/O ports are defined as input (inputs are at high-impedance), since the I/O control registers (TRISA, TRISB, TRISC, TRISD and TRISE) are all set. 6.1 6.

PIC16F5X 6.8 6.8.1 EXAMPLE 6-1: I/O Programming Considerations BIDIRECTIONAL I/O PORTS Some instructions operate internally as read followed by write operations. The BCF and BSF instructions, for example, read the entire port into the CPU, execute the bit operation and re-write the result. Caution must be used when these instructions are applied to a port where one or more pins are used as input/outputs.

PIC16F5X 7.0 TIMER0 MODULE AND TMR0 REGISTER Counter mode is selected by setting the T0CS bit (OPTION<5>). In this mode, Timer0 will increment either on every rising or falling edge of pin T0CKI. The incrementing edge is determined by the source edge select bit T0SE (OPTION<4>). Clearing the T0SE bit selects the rising edge. Restrictions on the external clock input are discussed in detail in Section 7.1 “Using Timer0 with an External Clock”.
PIC16F5X FIGURE 7-3: TIMER0 TIMING: INTERNAL CLOCK/PRESCALER 1:2 PC (Program Counter) Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Instruction Fetch MOVWF TMR0 MOVF TMR0,W MOVF TMR0,W MOVF TMR0,W MOVF TMR0,W MOVF TMR0,W Timer0 PC - 1 PC T0 PC + 1 PC + 3 T0 + 1 Write TMR0 executed TABLE 7-1: PC + 4 PC + 5 Read TMR0 reads NT0 Read TMR0 reads NT0 PC + 6 NT0 + 1 NT0 Instruction Execute Address PC + 2 Read TMR0 reads NT0 Read TMR0 reads
PIC16F5X 7.1 Using Timer0 with an External Clock When a prescaler is used, the external clock input is divided by the asynchronous ripple counter-type prescaler so that the prescaler output is symmetrical. For the external clock to meet the sampling requirement, the ripple counter must be taken into account. Therefore, it is necessary for T0CKI to have a period of at least 4TOSC (and a small RC delay of 40 ns) divided by the prescaler value.
PIC16F5X 7.2.1 SWITCHING PRESCALER ASSIGNMENT To change prescaler from the WDT to the Timer0 module, use the sequence shown in Example 7-2. This sequence must be used even if the WDT is disabled. A CLRWDT instruction should be executed before switching the prescaler. The prescaler assignment is fully under software control (i.e., it can be changed “on-the-fly” during program execution).
PIC16F5X 8.0 SPECIAL FEATURES OF THE CPU What sets a microcontroller apart from other processors are special circuits that deal with the needs of realtime applications. The PIC16F5X family of microcontrollers have a host of such features intended to maximize system reliability, minimize cost through elimination of external components, provide powersaving operating modes and offer code protection.
PIC16F5X 8.2 8.2.2 Watchdog Timer (WDT) The Watchdog Timer (WDT) is a free running on-chip RC oscillator which does not require any external components. This RC oscillator is separate from the RC oscillator of the OSC1/CLKIN pin. That means that the WDT will run even if the clock on the OSC1/CLKIN and OSC2/CLKOUT pins have been stopped, for example, by execution of a SLEEP instruction. During normal operation or Sleep, a WDT Reset or Wake-up Reset generates a device Reset.
PIC16F5X 8.3 Power-Down Mode (Sleep) A device may be powered down (Sleep) and later powered up (wake-up from Sleep). 8.3.1 SLEEP The Power-down mode is entered by executing a SLEEP instruction. If enabled, the Watchdog Timer will be cleared but keeps running, the TO bit (Status<4>) is set, the PD bit (Status<3>) is cleared and the oscillator driver is turned off. The I/O ports maintain the status they had before the SLEEP instruction was executed (driving high, driving low or high-impedance).

PIC16F5X 9.0 INSTRUCTION SET SUMMARY Each PIC16F5X instruction is a 12-bit word divided into an opcode, which specifies the instruction type, and one or more operands which further specify the operation of the instruction. The PIC16F5X instruction set summary in Table 9-2 groups the instructions into byteoriented, bit-oriented, and literal and control operations. Table 9-1 shows the opcode field descriptions.
