1.1.3 Memory

Note: Features in italics ae NOT available in the 56F8156 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 programmable for 0 - 30 wait states

— Access up to 1MB of program memory or 1MB of data memory

1.1.4 Peripheral Circuits

Note: Features in italics are NOT available in the 56F8156 device.

• Pulse Width Modulator:

— In the 56F8356, two Pulse Width Modulator modules, each 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

— In the 56F8156, 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 56F8356, two four-input Quadrature Decoders or two additional Quad Timers

— In the 56F8156, 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 56F8356, four dedicated general-purpose Quad Timers totaling three dedicated pins: Timer C

with one pin and Timer D with two pins

— In the 56F8156, two Quad Timers; Timer A and Timer C both work in conjunction with GPIO

• Optional on-chip regulator

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