Description

The AT89C51RB2/RC2 is a high-performance Flash version of the 80C51 8-bit micro-

controllers. It contains a 16K or 32K Bytes 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 VCC pin.

The AT89C51RB2/RC2 retains all features of the 80C52 with 256 Bytes of internal

RAM, a 9-source 4-level interrupt controller and three timer/counters.
