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).
