8-bit MCU with CAN controller and Flash

1. Description

Part of the CANary

dedicated

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.

2. Features

Rev.A- May 17, 2001

80C51 core architecture:

A 10-bit resolution analog to digital converter (ADC)

with 8 multiplexed inputs

Full CAN controller:

256 bytes of on-chip RAM

256 bytes of on-chip ERAM

16 Kbytes of on-chip Flash memory

Read/Write cycle : 10k

Data Retention 10 years at 85 C

2 Kbytes of on-chip Flash for Bootloader

2 Kbytes of on-chip EEPROM

Read/Write cycle : 100k

14-source 4-level interrupt

Three 16-bit timer/counter

Full duplex UART compatible 80C51

maximum crystal frequency 40 MHz. In X2 mode,

20 MHz (CPU core, 40 MHz)

three or four ports: 16 or 20 digital I/O lines

two-channel 16-bit PCA with:

Double Data Pointer

21-bit watchdog timer (including 7 programmable

bits)

Separate power supply for analog

Fully compliant with CAN standard rev 2.0 A

and 2.0 B

Optimized

management (via SFR)

4 independent message objects:

PWM (8-bit)

High-speed output

Timer and edge capture

Each message object programmable on

transmission or reception

Preliminary

the

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.
