Our AT89Sxx Development Board provides a very simple and cost effective platform for prototyping solution.  The compact design provides connection to all the pins of the microcontroller for the user.

Features

  • Prototyping solution available for 40-pin AT89xx series microcontroller from ATMEL
  • All the four ports available to the user via standard 10 pin box header with supply of 5 VDC for interfacing circuits
  • ISP (In circuit Serial Programming) connector available for chips with ISP support
  • 11.0592 MHz crystal on board
  • Pull-up resistor network for Port 0 of the microcontroller
  • UART level shifter MAX232 IC, on board for easy connection of the board to the RS232 devices
  • Jumper selectable connection available for connecting the UART level Shifter to the port pins
  • On board voltage regulator available for sourcing regulated 5V @ up to 1A voltage to the board and connecting circuit
  • Power-On LED indicator
  • AUX Power source of 5 VDC available on a PBT connector for sourcing DC supply to interfacing circuits
  • Four mounting holes of 3.2 mm each
  • PCB dimensions 74 mm x 97 mm

    Which software should I use for programming the microcontroller? Will keil uVision with ISP programmer software work while programming the uC using this development board? Do you use some other software?

      Any ISP programmer connected to CN5 will work. Be sure to properly connect the ISP pins to the board.
