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. 01 — 21 May 2007
Product data sheet
1. General description
The P89CV51RB2/RC2/RD2 are 80C51 microcontrollers with 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 device when compared to the
P89C51RB2/RC2/RD2 devices are the inclusion of an SPI interface, and increase in
RAM, and the ability to erase code memory in 128-byte pages.
The IAP capability combined with the 128-byte page size allows for efficient use of the
code memory for non-volatile data storage.
2. Features
2.1 Principal features
„ Supports 12-clock (default) or 6-clock mode selection via ISP or parallel programmer
„ 6-clock/12-clock mode programmable “on-the-fly” by SFR bit
„ Peripherals (PCA, timers, UART) may use either 6-clock or 12-clock mode while the
CPU is in 6-clock mode
„ 128-byte page erase for efficient use of code memory as non-volatile data storage
„ 0 MHz to 40 MHz operating frequency in 12x mode, 20 MHz in 6x mode
„ 16/32/64 kB of on-chip flash user code memory with ISP and IAP
„ 1 kB RAM
„ SPI (Serial Peripheral Interface) and enhanced UART
„ PCA (Programmable Counter Array) with PWM and Capture/Compare functions
„ Three 16-bit timers/counters
2.2 Additional features
„ Four 8-bit I/O ports
„ WatchDog Timer (WDT)
„ 30 ms page erase, 150 ms block erase
„ PLCC44 and TQFP44 packages
„ Ten interrupt sources with four priority levels
„ Second DPTR register
„ Low EMI mode (ALE inhibit)

I/O

internal
pull-up
Port 2: Port 2 is an 8-bit bidirectional I/O port with internal pull-ups.
Port 2 pins are pulled HIGH by the internal pull-ups when ‘1’s are
written to them and can be used as inputs in this state. As inputs,
Port 2 pins that are externally pulled LOW will source current (IIL)
because of the internal pull-ups. Port 2 sends the high-order
address byte during fetches from external program memory and
during accesses to external Data Memory that use 16-bit address
(MOVX@DPTR). In this application, it uses strong internal pull-ups
when transitioning to ‘1’s.
