SM 8051

SM 8051

SM 8051 module offers a quick way to use P89V51RD2 microcontrollers for any application. These modules are "self contained" - that is, they include some minimum necessary components surrounding the microcontroller chip, for example Reset circuit, crystal for clock etc. Further, these modules come in through-hole package, suitable for quick prototyping as well as production. This module can also be used for robotics projects.


  • Supported microcontrollers:8051 (P89V51RD2)
  • On-chip 64KB ISP+IAP flash, 1KB SRAM
  • 5 V Operating voltage from 0 to 40 MHz
  • 64 kB of on-chip Flash program memory with ISP (In-System Programming) and IAP (In Application Programming)
  • Supports 12-clock (default) or 6-clock mode selection via software or ISP
  • SPI (Serial Peripheral Interface) and enhanced UART
  • Single 8-bit D/A converter provides variable analog output.
  • Two on chip 8 Bit ADC provides 4 channels input.
  • Separate 2-pin berg strip for selecting Program and Run mode
  • Compact footprint, 35 mm X 45 mm. Pins available in such a way so that the module can be mounted in the FRC socket like an IC. Thus giving your hardware a modular design.
  • Four 8-bit I/O ports with three high-current Port 1 pins (16 mA each)
  • Three 16-bit timers/counters
  • Programmable Watchdog timer (WDT)
