Part of the CANaryTM family of 8-bit microcontrollers dedicated to CAN network applications, 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.
