Description

T89C51RB2/RC2 is a high-performance FLASH version of the 80C51 8-bit microcon-

trollers. It contains a 16K or 32K byte Flash memory block for program and data.

The 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

pin.

The T89C51RB2/RC2 retains all features of the 80C52 with 256 bytes of internal

RAM, a 7-source 4-level interrupt controller and three timer/counters.

In addition, the T89C51RB2/RC2 has a Programmable Counter Array, an XRAM of

1024 bytes, a Hardware Watchdog Timer, a Keyboard Interface, an SPI Interface,
