Evaluation Boards (8051)

8051 Evaluation Boards
and
8051 Single Board Computer

An Evaluation Board is a General Purpose board with a micro-controller and generally with a way to download and run user’s program on it. These are very useful as a quick development aid – for example, if you plan to make a micro-controller based product, it can be very convenient to buy and use an off-the-shelf evaluation board like Mini51 , so you can immediately start testing your software on the board.
A Single Board Computer (SBC) generally has lot of program memory and data memory, so users can test complex / large applications on it. Also, a SBC generally includes options for number of input and output devices like keyboard, display, serial / parallel port – somewhat similar to a desktop computer, but possibly smaller devices – for example an SBC may use a LCD instead of big CRT screen. SBCs are also quite useful for training, where students can write and run number of applications on the SBC.
Our 8051 evaluation boards and Single Board Computers can be used as companion tools for our C compiler for 8051 or as an independent hardware platform suitable for prototype testing, for training or even as an OE board for use in any product.

8051 Evaluation Board:

Mini51:

The Mini51 board is available with 5 different processors (NEW!!! now includes Analog I/O on-board or with I2C compatible add-on board)

Processor options:

P89C51RD2 @ 12 MHz (model: Mini51-P)
P89C668 @ 12 MHz (model: Mini51-P8)
P89C669 @ 12 MHz (model: Mini51-P9)

64KBytes / 96KBytes / 16KBytes / 62KBytes on-chip Flash, In System Programmable (ISP) Code Memory
768 bytes on-chip XRAM (for P89C51RD2)
or 7936 bytes on-chip XRAM (for P89C668)
or 2048 bytes on-chip data RAM (EDATA + XDATA) (for P89C669)
or 1024 bytes on-chip XRAM (for DS89C420)
or 2048 bytes on-chip XRAM (for ADuC831)

(Only Mini51-P9 or Mini51-U) second serial port available as TTL or RS232.
Serial communication cable for connecting to computer's COM port
14 pin connector for LCD (4 bit interface using on-chip port)
Optional LCD BackLighting Control via port pin
10 pin connector for 5 X 5 matrix keyboard
14 (or 12) unused port pins are brought out on a connector
On-board regulator to generate +5VDC (requires 9 Volts DC)
Accompanying disk contains ISP programming software and working example programs written in C to access the serial port, LCD and keyboard
I2C Compatible 64 KBytes EEPROM (24C512)
I2C Compatible Real Time Clock (DS1307) with Lithum Battery
(Only in Mini51-A831) on-chip 4KBytes EEPROM.
(Only in Mini51-A831) 8 Analog Inputs (12 bit), 2 analog outputs (12 bit), temperature sensor
(All models except Mini51-A831) Optional add-on board (SAIO) provides 8 Analog Inputs (8 bit), 2 analog outputs (8 bit). This SAIO add-on board connects to Mini51 over I2C bus, hence it does not consume extra port lines.

Please note, the LCD and keyboard are NOT supplied with this board, you need to buy those separately. The board only provides interface connector for the LCD and keyboard.

Depending on the selected processor, there are 5 different models of this board:

Mini51-P: With P89C51RD2 (only 768 bytes on-chip XRAM, 2X speed)
Mini51-P8: With P89C668 (7936 bytes on-chip XRAM, 2X speed)
Mini51-P9: With P89C669 (96K on-chip code memory, 2048 bytes on-chip data memory (EDATA + XDATA), 2X speed)
Mini51-U: With DS89C420 (1024 bytes on-chip XRAM, second serial port, upto 12X speed)
Mini51-A831: With ADuC831 (2048 bytes on-chip XRAM, 8 Analog Inputs + 2 Analog outputs, 12 bit resolution)

This board is suitable for testing a wide range of application programs. It provides large amount (64K / 96K / 16K / 62K) of on-chip Code Memory as well as some amount (768 / 7936 / 2048 / 1024 bytes) of on-chip XRAM data memory. Mini51-P9 and Mini51-U offer the advantage of second serial port. Mini51-U offers ultra-high speed. Mini51-A831 offers on-board, high resolution analog I/O. All other models can optionally use SAIO add-on board to get analog I/O. All the code memory can be programmed without removing the chip from the socket, with the convinience of the selector switch(es). Thus this board (in combination with SC51 - our C Compiler for 8051 ) is a complete development tool , and YOU DO NOT NEED A SEPARATE IC PROGRAMMER to work with this board.

You may download some example programs written for and tested with this board.
