Description
ATMEL Wireless and Microcontrollers T89C51RD2 is high performance CMOS Flash
version of the 80C51 CMOS single chip 8-bit microcontroller. It contains a 64
Kbytes Flash memory block for program and for data. The 64 Kbytes Flash memory
can be programmed either in parallel mode or in serial mode with the ISP
capability or with software. The programming voltage is internally generated
from the standard VCC pin.
The T89C51RD2 retains all features of the ATMEL Wireless and Microcontrollers
80C52 with 256 bytes of
internal RAM, a 7-source 4-level interrupt controller and three
timer/counters.
