High performance 8-bit micro-controller with on-chip Flash memory and CAN

The XC886/888CLM enhances the XC800 family of 8-bit μCs with a new member providing advanced networking capabilities by integrating both a CAN controller with 29-bit identifier and LIN support on a single chip. The on-chip MultiCAN modules reduce the CPU load by performing most of the functions required by the networking protocol (masking, filtering and buffering of CAN frames).

Additional key features include up to 32  KiB of embedded Flash memory, an intelligent PWM unit, a highly accurate 10-bit A/D converter with fast conversion speed, a CORDIC unit and a multiplication division unit (MDU) for fast mathematical computations.

The flexibility offered by the XC886/888CLM embedded Flash products is also expanded to include a family of compatible ROM versions for further cost saving potential in high volume production. The XC886/888CLM offers an optimized fit to a wide range of CAN networking applications including automotive body, controls for industrial and agricultural equipments, building controls for lifts/escalators, intelligent sensors, distributed I/O modules and industrial automation.
