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.

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 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 efﬁcient 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 ﬂash 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)
