Description

T89C51IC2 is a high performance FLASH version of the 80C51 8-bit microcontrollers.

It contains a 32-Kbytes Flash memory block for program and data.

The 32-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 V_CCpin.

The T89C51IC2 retains all features of the 80C52 with 256 bytes of internal RAM, a 7-

source 4-level interrupt controller and three timer/counters.
