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 VCC pin.  
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.
