Overview
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.
The IAP capability combined with the 128-B page size allows for efficient use of the code memory for non-volatile data storage.
