1.1.3 Memory

Note: Features in italics are NOT available in the 56F8165 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

— 512KB of Program Flash

— 4KB of Program RAM

— 32KB of Data Flash

— 32KB of Data RAM

— 32KB of Boot Flash

• EEPROM emulation capability

1.1.4 Peripheral Circuits

Note: Features in italics are NOT available in the 56F8165 device.

• Pulse Width Modulator module:

— In the 56F8365, 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 56F8165, 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 56F8365, two four-input Quadrature Decoders or two additional Quad Timers

— In the 56F8165, 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 56F8365, four dedicated general-purpose Quad Timers totaling six dedicated pins: Timer C with

two pins and Timer D with four pins

— In the 56F8165, two Quad Timers; Timer A and Timer C both work in conjunction with GPIO

• Optional On-Chip Regulator

• Up to two FlexCAN (CAN Version 2.0 B-compliant) modules with 2-pin port for transmit and receive

• Two Serial Communication Interfaces (SCIs), each with two pins (or four additional GPIO lines)

• Up to two Serial Peripheral Interfaces (SPIs), both with configurable 4-pin port (or eight additional GPIO

lines); SPI1 can also be used as Quadrature Decoder 1 or Quad Timer B

• Computer Operating Properly (COP)/Watchdog timer
