AT89C51AC3 CPU Module

AT89C51AC3 CPU Module is a module-based single-chip microcontroller family MCS-51 AT89C51AC3 that features 8 channels of ADC 10 bits and is compatible with the DT-COMBO Basic Base Board. AT89C51AC3 on this module has been equipped with the bootloader from Atmel (the default bootloader) so that the process of In-System Programming can be done directly via the UART without the aid of an external programmer device. DT-51 AT89C51AC3 can be used to develop simple to complex applications such as applications that use sensor device that has an analog voltage output.


  • Based AT89C51AC3 with features:
  • 64 kbytes of flash memory.
  • 256 bytes of RAM.
  • 2 kbytes EEPROM.
  • Expanded RAM with capacity up to 2048 bytes that can be selected by software.
  • 6 clock / machine cycle in X2 mode.
  • 14 interrupt sources.
  • 3 pieces of Timer / Counter 16 bit.
  • Dual Data Pointer.
  • 8 channel ADC with a resolution of 10 bits.
  • 5 channel PCA (Programmable Counter Array) 16 bits which can be used as PWM.
  • Watchdog Timer.
  • Crystal oscillator at 11.0592 MHz.
  • Equipped with an internal bootloader from Atmel (the default bootloader) to assist the process of In-System Programming via the UART without an external programmer device.
  • Having a path Input / Output up to 34 pins.
  • Equipped with Full Duplex UART interface.
  • Process In-System Programmer uses the help of software FLIP (Flexible In-System Programmer) from ATMEL.
  • Equipped with PLCC socket so as to facilitate the replacement IC in the event of damage.
  • Equipped with tactile switches HWB to help programming using the bootloader.
  • Equipped with a chip EMI filter to minimize noise from the power supply.
  • Equipped with the ADC reference voltage circuit that generates a reference voltage +3 VDC.
  • Power supply 2.7 to 5.5 VDC and is equipped with a LED power indicator.
  • Compatible with DT-COMBO Basic Base Board and can be used with other modules by considering the pin configuration.
  • Equipped with software BASCOM-8051 version of the Demo and FLIP.
  • module dimensions : 6.0 cm (l) x 5.3 cm (w) x 1.7 cm (h).
