Product Brief The C505CA enhances the C500 family of 8-bit microcontrollers by a new member which provides full CAN version 2.0B integrated On-Chip. The C505CA meets the current requirements for increasingly small controllers with high performance, optimized EMC behavior and fast communication between decentralized sensors, actuators and the host. The device provides 32 KByte of OTP or 16/32 KByte of ROM, 256 Byte of RAM, 1 KByte of XRAM, CAN Version 17 2.0B, an asynchronous/synchronous serial interface and highly accurate 10-bit ADC integrated on chip. With an external clock rate of 20 MHz, the C505CA has an instruction time of 300 ns. Typical applications for the C505CA are automotive body and industrial control.
