Preliminary speciﬁcation

CAN Serial Linked I/O device (SLIO) with

digital and analog port functions

P82C150

FEATURES

• Single-chip I/O device with CAN protocol controller

• Meets CAN protocol specification version 2.0 A and B

(passive) with restricted bit timing

• Fully integrated clock oscillator (no crystal required)

• 16 configurable digital or analog I/O port pins

• Each of the port pins individually configurable via

CAN-bus: port direction, port mode and event capture

facilities for inputs (event driven or polling)

• Up to sixteen digital inputs; automatic transmission of a

CAN message on a change on inputs individually

selectable

• Up to sixteen 3-state outputs

• Up to two quasi-analog outputs with 10-bit accuracy

• 10-bit analog-to-digital converter with up to six

multiplexed analog input channels (for accuracy see

Section 11.6)

• Two general purpose comparators

• Bit rate from 20 kbit/s up to 125 kbit/s using internal

oscillator

• Automatic bit rate detection and calibration

• Up to sixteen P82C150 nodes for one CAN-bus system

• Four identifier bits programmable

• SLIO functions controlled by a single intelligent node

(‘host’)

• Sleep-mode with wake-up via CAN-bus

• Differential CAN-bus input comparator and CAN-bus

output driver

• Supply voltage: 5 V ±4%

• Operating temperature: two ranges −40 to +85 °C and

−40 to +125 °C.

GENERAL DESCRIPTION

The P82C150 is a single-chip 16-bit I/O device including a

Controller Area Network (CAN) protocol controller with

automatic bit rate detection and calibration. It features 16

configurable I/O port pins with programmable direction,

digital and analog modes.

The P82C150 provides a configurable event capture

facility supporting automatic transmission caused by a

change on the port input pins.

The clock oscillator requires no external components,

thus, the cost of the CAN link is reduced significantly.

The P82C150 is a very cost-effective way to increase the

I/O capability of a microcontroller based CAN node as well

as to reduce the amount and complexity of wiring.

Advanced safety is provided by the CAN protocol.

Applications:

• Body electronics and instrumentation in automotive

applications

• Sensor/actuator interface in automotive and general

industrial applications

• Extension of I/O capabilities of microcontroller based

CAN nodes.
