56F8357/56F8157 Features

1.1.3 Memory

Note: Features in italics are NOT available in the 56F8157 device.

• Harvard architecture permits as many as three simultaneous accesses to program and data memory

• Flash security protection feature

• On-chip memory, including a low-cost, high-volume flash solution

— 256KB of Program Flash

— 4KB of Program RAM

— 8KB of Data Flash

— 16KB of Data RAM

— 16KB of Boot Flash

• Off-chip memory expansion capabilities provide a simple method for interfacing additional external

memory and/or peripheral devices

— Access up to 4MB of external program memory or 32MB of external data memory

— External accesses supported at up to 60MHz (zero wait states)

• EEPROM emulation capability

1.1.4 Peripheral Circuits

Note: Features in italics are NOT available in the 56F8157 device.

• Pulse Width Modulator:

— In the 56F8357, two Pulse Width Modulator modules, each with six PWM outputs, three Current Sense

inputs, and four Fault inputs; fault-tolerant design with dead time insertion; supports both center-aligned

and edge-aligned modes

— In the 56F8157, one Pulse Width Modulator module with six PWM outputs, three Current Sense inputs,

and three Fault inputs; fault-tolerant design with dead time insertion; supports both center-aligned and

edge-aligned modes

• Four 12-bit, Analog-to-Digital Converters (ADCs), which support four simultaneous conversions with

quad, 4-pin multiplexed inputs; ADC and PWM modules can be synchronized through Timer C, channels

2 and 3

• Quadrature Decoder:

— In the 56F8357, two four-input Quadrature Decoders or two additional Quad Timers

— In the 56F8157, one four-input Quadrature Decoder, which works in conjunction with Quad Timer A

• Temperature Sensor can be connected, on the board, to any of the ADC inputs to monitor the on-chip

temperature

• Quad Timer:

— In the 56F8357, four dedicated general-purpose Quad Timers totaling six dedicated pins: Timer C with

two pins and Timer D with four pins

— In the 56F8157, two general-purpose Quad Timers; Timer A works in conjunction with Quadrature

Decoder 0 or GPIO and Timer C works in conjunction with GPIO

• FlexCAN (CAN Version 2.0 B-compliant ) module with 2-pin port for transmit and receive
