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.
