AHT373

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.

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.

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.
