GENERAL DESCRIPTION

The SJA1000 is a stand-alone controller for the Controller Area Network (CAN) used within automotive and general industrial environments. It is the successor of the PCA82C200 CAN controller (BasicCAN) from Philips Semiconductors. Additionally, a new mode of operation is implemented (PeliCAN) which supports the CAN 2.0B protocol specification with several new features.

FEATURES

• Pin compatibility to the PCA82C200 stand-alone CAN controller

• Electrical compatibility to the PCA82C200 stand-alone CAN controller

• PCA82C200 mode (BasicCAN mode is default)

• Extended receive buffer (64-byte FIFO)

• CAN 2.0B protocol compatibility (extended frame passive in PCA82C200 compatibility mode)

• Supports 11-bit identifier as well as 29-bit identifier

• Bit rates up to 1 Mbits/s

• PeliCAN mode extensions:

  – Error counters with read/write access

  – Programmable error warning limit

  – Last error code register

  – Error interrupt for each CAN-bus error

  – Arbitration lost interrupt with detailed bit position

  – Single-shot transmission (no re-transmission)

  – Listen only mode (no acknowledge, no active error flags)

  – Hot plugging support (software driven bit rate detection)

  – Acceptance filter extension (4-byte code, 4-byte mask)

  – Reception of ‘own’ messages (self reception request)

• 24 MHz clock frequency

• Interfaces to a variety of microprocessors

• Programmable CAN output driver configuration

• Extended ambient temperature range (−40 to +125 °C).
