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

The P89CV51RB2 P89CV51RC2/P89CV51RD2 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 P89CV51RC2/P89CV51RD2 devices. Both the In-System Programming (ISP) and In-Application Programming (IAP) boot codes are upward compatible. Additional features of the P89CV51RB2 P89CV51RC2/P89CV51RD2 devices compared to the P89C51RB2 P89CV51RC2/P89CV51RD2 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.
