Specifications

6 Motorola 56F8300 Hybrid Controller Family Motorola
Introduction
• Flexible External Memory Interface (EMI)
— Some 56F8300 devices include a flexible External Memory Interface that enables glueless
connection with programmable chip selects and separate wait state generation, enabling
the most cost-effective and lowest chip count possible when interfacing to external
memory or peripherals
— The EMI interface can be configured as GPIO
• Voltage regulator and power supervisor
— The chips come equipped with an on-board voltage regulator and power supervisor. When
supplied with a 3.3V voltage, the chip creates all the internal voltages required.
— Includes features such as Power-On Reset (POR) and low-voltage detection, thereby
eliminating external components and saves system costs
• On-chip Relaxation Oscillator
— Some 56F8300 devices are equipped with a precision on-chip factory trimmed oscillator
(0.25% of 8 MHz), enabling the elimination of an external crystal and providing system
cost savings
• On-chip Clock Synthesis (OCCS)
— 56F8300 hybrid controllers are equipped with on-chip crystal and ceramic resonator
oscillator drive circuitry, enabling the direct connection of an external crystal or ceramic
resonator
— The OCCS capability includes a flexible, programmable Phase Locked Loop (PLL),
enabling selection of an exact operating frequency
— The OCCS also includes unique loss-of-lock detection, enabling the detection of a cut
crystal and the proper safety-critical shut down
• Quad Timer
— 56F8300 devices are equipped with powerful timer modules. Each timer module has four
independent 16-bit timers that can be:
— Cascaded
— Used for input capture
— Used to generate output waveforms
— Used to trigger the ADC
— Used to generate auxiliary PWM waveforms
— Used as a Digital-to-Analog Converter (DAC) when utilized in conjunction with an
external low-pass filter
• Quadrature Decoder
— Full-featured, four-input decoder with:
— 32 bit directional position tracking
— Programmable digital filtered inputs
— Integral watchdog timer to flag a non-rotating shaft condition
— Ability to calculate velocity measurement
• Three-Phase PWM module
— The high-performance 15-bit PWMs can be used in edge-aligned and center-aligned
modes, as well as in complementary and independent modes and have programable
dead-time generation
— These PWM modules have a sophisticated set of programmable fault lines that do not
require a system clock for proper operation
— These and other features make these PWM modules industry leaders in safety, reliability,
and performance
