MCU 8-bit P89 80C51 CISC 16KB Flash 5V 44-Pin PLCC Tube, P89CV51RB2FA,512, NXP

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.

  • Supports 12-clock (default) or 6-clock mode selection via ISP or parallel programmer
  • 6-clock/12-clock mode programmable “on-the-fly” by an SFR bit
  • Peripherals (PCA, timers, UART) may use either 6-clock or 12-clock mode while the CPU is in 6-clock mode
  • 128-B page erase for efficient use of code memory as non-volatile data storage
  • 0 MHz to 40 MHz operating frequency in 12× mode, 20 MHz in 6× 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
  • Four 8-bit I/O ports
  • WatchDog Timer (WDT)
  • 30 ms page erase, 150 ms block erase
