Description
Part of the CANary
TM
family of 8-bit microcontrollers dedicated to CAN network applica-
tions, the T89C51CC02 is a low-pin count 8-bit Flash microcontroller.
In X2 Mode a maximum external clock rate of 20 MHz reaches a 300 ns cycle time.
Besides the full CAN controller T89C51CC02 provides 16K Bytes of Flash memory
including In-System Programming (ISP), 2K Bytes Boot Flash Memory, 2K Bytes
EEPROM and 512 Bytes RAM.
Special attention is payed to the reduction of the electro-magnetic emission of
T89C51CC02.
