Enhanced 8-bit Microcontroller with CAN Controller and Flash Memory T89C51CC01 AT89C51CC01 Rev. 4129N–CAN–03/08 1 • Power Supply: 3V to 5.5V • Temperature Range: Industrial (-40° to +85°C) • Packages: VQFP44, PLCC44 Description The T89C51CC01 is the first member of the CANaryTM 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 T89C51CC01 provides 32K Bytes of Flash memory including In-System-Programming (ISP), 2K Bytes Boot Flash Memory, 2K Bytes EEPROM and 1.2-Kbyte RAM. Special attention is paid to the reduction of the electro-magnetic emission of T89C51CC01.

A CPU "write to latch" signal initiates transfer of internal bus data into the type-D latch. A CPU "read latch" signal transfers the latched Q output onto the internal bus. Similarly, a "read pin" signal transfers the logical level of the Port pin. Some Port data instructions activate the "read latch" signal while others activate the "read pin" signal. Latch instructions are referred .
