This document introduces the features and characteristics of the 4129L-CAN product
The T89C51CC01 is an 8‑bit microcontroller from Atmel’s CANary family, featuring 32 KB of flash, 256 B of RAM, 2 KB of EEPROM, a 10‑bit ADC with eight multiplexed inputs, and a full CAN controller compliant with CAN 2.0A/B. It supports a wide range of packages (VQFP44, PLCC44, CA‑BGA64) and operates from 3 V to 5.5 V in an industrial temperature range.
The device includes three 16‑bit timers, five ports (32 I/O lines), a 21‑bit watchdog, and on‑chip emulation logic. It offers in‑system programming via CAN, UART, and IAP, and provides up to 1 Mbit/s CAN transfer rate when driven by an 8 MHz crystal.
