Basic Functional Description
n CAN I/F — CAN serial bus interface block as described
in the CAN specification part 2.0B (Passive)
— Interface rates up to 250k bit/s are supported utilizing
standard message identifiers
n Programmable double buffered USART
n A/D — 8-bit, 8 channel, 1-LSB Resolution, with improved
Source Impedance and improved channel to channel
cross talk immunity
n Multi-Input-Wake-Up (MIWU) — edge selectable wake-up
and interrupt capability via input port and CAN interface
(Port L, Port M and CAN I/F); supports Wake-Up
capability on SPI, USART, and T2 capture
n Port C — 8-bit bi-directional I/O port
n Port D — 8-bit Output port with high current drive
capability (10 mA)
n Port F — 8-bit bidirectional I/O
n Port G — 8-bit bidirectional I/O port, including alternate
functions for:
— MICROWIREInput and Output
— Timer 1 Input or Output (Depending on mode
selected)
— External Interrupt input
— WATCHDOG Output
n Port I — 8-bit input port combining either digital input, or
up to eight A/D input channels
n Port L — 8-bit bidirectional I/O port, including alternate
functions for:
— USART Transmit/Receive I/O
— Multi-input-wake up (MIWU on all pins)
n Port M — 8-bit I/O port, with the following alternate
function
— SPI Interface
— MIWU
— CAN Interface Wake-up (MSB)
— Timer 2 Input or Output (Depending on mode
selected)
n Port N — 8-bit bidirectional I/O
— SPI Slave Select Expander
n Two 16-bit multi-function Timer counters (T1 and T2)
plus supporting registers
— (I/P Capture, PWM and Event Counting)
n Idle timer — Provides a basic time-base counter, (with
interrupt) and automatic wake up from IDLE mode
programmable
n MICROWIRE/PLUS — MICROWIRE serial peripheral
interface, supporting both Master and Slave operation
n HALT and IDLE — Software programmable low current
modes
— HALT — Processor stopped, Minimum current
— IDLE — Processor semi-active more than 60% power
saving
n 8 kBytes ROM and 192 bytes of on board static RAM
n SPI Master/Slave interface includes 12 bytes Transmit
and 12 bytes Receive FIFO Buffers. Operates up to 1M
Bit/S
n On board programmable WATCHDOG and CLOCK
Monitor
Applications
n Automobile Body Control and Comfort System
n Integrated Driver Informaiton Systems
n Steering Wheel Control
n Car Radio Control Panel
n Sensor/Actuator Applications in Automotive and
Industrial Control
