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).
