AT89C51RE2 Development Board

The AT89C51RE2 Development Board is ideal for designing new 8051 applications or as the main board for a new embedded system. The AT89C51RE2 is a high performance Flash version of the 80C52 8-bit microcontroller range. Program download and run is easily executed in-system by an RS232 connection to the computer parallel port, no programmer is required. The board utilises the advanced AT89C51RE2 Atmel microcontroller with a huge 128k of In-System Flash Memory, running at 18.432Mhz, with an SPI Interface, Two Full Duplex Enhanced UART's, PCA and lots more. All power supply components and main crystal is in place for the microcontroller. Connectors are provided for RS232, UART's, power and all I/O pins, via standard polarized connections and IDCC connectors. Download software is included, together with code examples in assembly language, to get you up and running quickly.

Please note: Power supply is not included.
