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