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

  1. 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?
