General description
The P89CV51RB2/RC2/RD2 are three types of 80C51 microcontroller with respectively
16 kB/32 kB/64 kB ash 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 efcient use of the code
memory for non-volatile data storage.

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-y” by an SFR bit
I Peripherals (PCA, timers, UART) may use either 6-clock or 12-clock mode while the
CPU is in 6-clock mode
I 128-B page erase for efcient use of code memory as non-volatile data storage
I 0 MHz to 40 MHz operating frequency in 12× mode, 20 MHz in 6× mode
I 16/32/64 kB of on-chip ash user-code memory with ISP and IAP
I 1 kB RAM
I SPI (Serial Peripheral Interface) and enhanced UART
I PCA (Programmable Counter Array) with PWM and capture/compare functions
I Three 16-bit timers/counters
2.2 Additional features
I Four 8-bit I/O ports
I WatchDog Timer (WDT)
I 30 ms page erase, 150 ms block erase
I PLCC44 and TQFP44 packages
I Ten interrupt sources with four priority levels
I Second DPTR register
I Low EMI mode (ALE inhibit)
