P89CV51RB2 - Microcontroller

Download the P89CV51RB2 datasheet PDF. This datasheet also covers the P89CV51RD2 variant, as both devices belong to the same microcontroller family and are provided as variant models within a single manufacturer datasheet.

General Description

The P89CV51RB2/RC2/RD2 are three types of 80C51 microcontroller with respectively 16 kB/32 kB/64 kB flash and 1 kB of data RAM.

These devices are designed to be drop-in and software-compatible replacements for the popular P89C51RB2/RC2/RD2 devices.

Key Features

  • of the P89CV51RB2/RC2/RD2 devices compared to the P89C51RB2/RC2/RD2 are the inclusion of an SPI interface, larger RAM size, and the ability to erase code memory in 128-B page blocks. The IAP capability combined with the 128-B page size allows for efficient use of the code memory for non-volatile data storage. 2. Features 2.1 Principal features I Supports 12-clock (default) or 6-clock mode selection via ISP or parallel programmer I 6-clock/12-clock mode programmable “on-the-fly” by an SFR bit I Per.

P89CV51RB2/RC2/RD2 8-bit 80C51 5 V low power 64 kB flash microcontroller with 1 kB RAM, SPI, 6-clock CPU with 6/12-clock peripherals Rev. 03 — 25 August 2009 Product data sheet 1. General description The P89CV51RB2/RC2/RD2 are three types of 80C51 microcontroller with respectively 16 kB/32 kB/64 kB flash and 1 kB of data RAM. These devices are designed to be drop-in and software-compatible replacements for the popular P89C51RB2/RC2/RD2 devices. Both the In-System Programming (ISP) and In-Application Programming (IAP) boot codes are upward compatible. Additional features of the P89CV51RB2/RC2/RD2 devices compared to the P89C51RB2/RC2/RD2 are the inclusion of an SPI interface, larger RAM size, and the ability to erase code memory in 128-B page blocks.
