1. SYSTEM OVERVIEW
C8051F330/1 devices are fully integrated mixed-signal System-on-a-Chip MCUs. Highlighted features are listed
below. Refer to
Table 1.1 for specific product feature selection.
• High-speed pipelined 8051-compatible microcontroller core (up to 25 MIPS)
• In-system, full-speed, non-intrusive debug interface (on-chip)
• True 10-bit 200 ksps 16-channel single-ended/differential ADC with analog multiplexer
• 10-bit Current Output DAC
• Precision programmable 25 MHz internal oscillator
• 8k bytes of on-chip FLASH memory
• 768 bytes of on-chip RAM
•SMBus/I
2
C, Enhanced UART, and Enhanced SPI serial interfaces implemented in hardware
• Four general-purpose 16-bit timers
• Programmable Counter/Timer Array (PCA) with three capture/compare modules and Watchdog Timer function
• On-chip Power-On Reset, VDD Monitor, and Temperature Sensor
• On-chip Voltage Comparator
• 17 Port I/O (5V tolerant)
With on-chip Power-On Reset, VDD monitor, Watchdog Timer, and clock oscillator, the C8051F330/1 devices are
truly stand-alone System-on-a-Chip solutions. The FLASH memory can be reprogrammed even in-circuit, providing
non-volatile data storage, and also allowing field upgrades of the 8051 firmware. User software has complete control
of all peripherals, and may individually shut down any or all peripherals for power savings.
The on-chip Silicon Labs 2-Wire (C2) Development Interface allows non-intrusive (uses no on-chip resources), full
speed, in-circuit debugging using the production MCU installed in the final application. This debug logic supports
inspection and modification of memory and registers, setting breakpoints, single stepping, run and halt commands.
All analog and digital peripherals are fully functional while debugging using C2. The two C2 interface pins can be
shared with user functions, allowing in-system debugging without occupying package pins.
Each device is specified for 2.7 V-to-3.6 V operation over the industrial temperature range (-45°C to +85°C). The
Port I/O and /RST pins are tolerant of input signals up to 5
V. The C8051F330/1 are available in a 20-pin MLP pack-
age as shown in Figure 1.1 and Figure 1.2, respectively.
