P89V51RB2/RC2/RD2

8-bit 80C51 5 V low power 16/32/64 kB Flash microcontroller

with 1 kB RAM

Rev. 03 — 02 December 2004

Product data

1. General description

The P89V51RB2/RC2/RD2 are 80C51 microcontrollers with 16/32/64 kB Flash and

1024 bytes of data RAM.

A key feature of the P89V51RB2/RC2/RD2 is its X2 mode option. The design

engineer can choose to run the application with the conventional 80C51 clock rate

(12 clocks per machine cycle) or select the X2 mode (6 clocks per machine cycle) to

achieve twice the throughput at the same clock frequency. Another way to beneﬁt

from this feature is to keep the same performance by reducing the clock frequency by

half, thus dramatically reducing the EMI.

The Flash program memory supports both parallel programming and in serial

In-System Programming (ISP). Parallel programming mode offers gang-programming

at high speed, reducing programming costs and time to market. ISP allows a device

to be reprogrammed in the end product under software control. The capability to

ﬁeld/update the application ﬁrmware makes a wide range of applications possible.

The P89V51RB2/RC2/RD2 is also In-Application Programmable (IAP), allowing the

Flash program memory to be reconﬁgured even while the application is running.

2. Features

■ 80C51 Central Processing Unit

■ 5 V Operating voltage from 0 MHz to 40 MHz

■ 16/32/64 kB of on-chip Flash user code memory with ISP (In-System

Programming) and IAP (In-Application Programming)

■ Supports 12-clock (default) or 6-clock mode selection via software or ISP

■ SPI (Serial Peripheral Interface) and enhanced UART

■ PCA (Programmable Counter Array) with PWM and Capture/Compare functions

■ Four 8-bit I/O ports with three high-current Port 1 pins (16 mA each)

■ Three 16-bit timers/counters

■ Programmable watchdog timer

■ Eight interrupt sources with four priority levels

■ Second DPTR register

■ Low EMI mode (ALE inhibit)

■ TTL- and CMOS-compatible logic levels
