Description

The AT89C51CC03 is a member of the family of 8-bit microcontrollers dedicated to CAN

network applications.

In X2 mode a maximum external clock rate of 20 MHz reaches a 300 ns cycle time.

Besides the full CAN controller AT89C51CC03 provides 64K Bytes of Flash memory

including In-System Programming (ISP), 2K Bytes Boot Flash Memory, 2K Bytes

EEPROM and 2048 byte ERAM.

Primary attention is paid to the reduction of the electro-magnetic emission of

AT89C51CC03.
