Rainbow Electronics T89C51CC02 - Manual

Rev.A- May 17, 2001 1
Preliminary
T89C51CC02
8-bit MCU with CAN controller and Flash
1. Description
Part of the CANary
TM
family of microcontrollers
dedicated to CAN network applications, the
T89C51CC02 is a low pin count 8-bit Flash
microcontroller.
While remaining fully compatible with the 80C51 it
offers a superset of this standard 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
16 Kbytes of Flash memory including In-system
Programming (ISP), 2-Kbyte Boot Flash Memory, 2-
Kbyte EEPROM and 512 bytes RAM.
Special attention is payed to the reduction of the electro-
magnetic emission of T89C51CC02.
