High speed 80C32 compatible core:
- High performance 4 clocks/machine cycles (8032 = 12)
- Low Power: typically 1/3 power for equivalent 8032 throughput
- Maximum clock speed up to 25MHz at 5.0V
- Ultra-low stop mode power (typ. 1uA) "IDLE" mode (typ. 10mA)
- Multiple wake-up sources from STOP including key scan, 2-wire, host I/F, or external interrupt
- Three 16-bit timers, 1 serial port
- 256-byte scratchpad
- 256 bytes MOVX RAM
Keyboard Control:
- Replaces 8042 and key scan microcontroller
- 2 Parallel I/O ports for key scan outputs
- One interrupt-driven 8-bit input port to initiate key-scan sequence
Input/Output:
- Total of eleven 8-bit I/O ports; all pins can individually programmed to serve as general purpose digital input/output.
- 8-bit port supports one or more special functions:
  - Port 0, 2, 3: external program/data memory interface
  - Port 1, 3: UART, 2-Wire serial, timers, external interrupt I/O.
  - Port 4, 8, 9: Key scan input/output
  - Port 5: A/D inputs
  - Port 6: PWM Outputs
  - Port 7: activity monitor, LED control
  - Port 10: GPIO
Analog input/output:
- Eight-channel, 10-bit A/D with power down mode supports charging NiMH rechargeable cells
- 4-channel, 8-bit PWM supports LCD brightness and contrast control
2-Wire bi-directional serial buses
- Master/slave multi-drop operation
- Manages on-board slaves or external I/O devices
Power Control
- Generates system power on reset
- Programmable power down pin states
