P89CV51RB2/RC2/RD2
8-bit 80C51 5 V low power 64 kB 鏗俛sh microcontroller with
1 kB RAM, SPI, 6-clock CPU with 6/12-clock peripherals
Rev. 01 鈥?5 October 2007
Product data sheet
1. General description
The P89CV51RB2/RC2/RD2 are three types of 80C51 microcontroller with respectively
16 kB/32 kB/64 kB 鏗俛sh 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 ef鏗乧ient 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 鈥渙n-the-鏗倅鈥?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 ef鏗乧ient use of code memory as non-volatile data storage
I
0 MHz to 40 MHz operating frequency in 12脳 mode, 20 MHz in 6脳 mode
I
16/32/64 kB of on-chip 鏗俛sh 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
