CAN microcontrollers for a full range of solutions

14 August 2002 DSP, Micros & Memory

CAN network are now found in widely varying types of automotive and industrial systems, calling for a range of different CAN capabilities and scalable MCU core performance. ST Microelectronics offers a family of five different CAN interfaces (pCAN, beCAN, bxDAN, FullCAN and cCAN) and a range of MCU capabilities with 8 to 32-bit data width.

pCAN:(Passive CAN) supports the 2,0B passive protocol. It has three transmit/receive mailboxes and two message identifier filters, two interrupt vectors and supports low power mode.

beCAN:(Basic-enhanced) supports the 2,0B active protocol. It has two prioritised transmit mailboxes and one receive FIFO up to four messages deep for realtime performance. Four scalable and configurable filters handle all message filtering by hardware to minimise CPU load. beCAN is ideal for medium-complexity car body and car radio systems.

bxCAN:(Basic-extended) has the beCAN features plus three transmit mailboxes, two independent receive FIFOs and eight filters. It is optimised for high-end car body and low-end gateway applications.

FullCAN: Is compatible with the Intel 82527 CAN controller. It has 14 transmit/receive mailboxes, one receive FIFO and two 29-bit identifier filters. FullCAN is ideal for engine management systems.

cCAN: Is one of the new generation of full CAN implementations. It has 32 transmit/receive mailboxes allowing a large number of messages to be handled statically and autonomously. Its receive mailboxes support FIFO mode. Each mailbox has its own associated filter. cCAN is ideal for high-end gateway and power train applications.

STs CAN MCU families extend through the 8-bit ST7 family; the 8/16-bit ST9 family; the 16-bit ST10 family; and the 32-bit MCU family.
