Specifications
89S8253 CPU running at 24 MHz 12K Program Flash, 2K Data EEPROM BASIC Interpreter or System Monitor Software Installed 60K Bytes of RAM ( 28K of which is battery-backed ) Small footprint: 4.5 by 4.0 inches Ample prototype space: 3.5 by 1.5 inches RS-232 ( RS-485 optional ) Serial Port 80C51 family compatible In-system programmable On-board voltage regulatorThe MICRO LAB-51 is an 8051-based single board computer ideally suited for laboratory use. It works well in both educational and product development settings. In an academic environment, instructors can demonstrate real world applications and students can implement projects. In the development lab, design engineers can easily create and test prototypes of their 8051-based products.
Standard Configuration with BASIC
In its standard configuration, the MICRO LAB-51 has BASIC-52 installed in Flash. BASIC-52 is a full-featured BASIC interpreter which supports floating-point math and most BASIC commands. BASIC is great for students because it is easily learned and used. Instructors can quickly demonstrate embedded computer principles with minimal effort.
Advanced Configuration with Debug Software
An advanced version of the MICRO LAB-51 is also available. It comes with the MD-51 system monitor installed in Flash. This configuration is suited to 8051-based product development because an engineer can download 8051 object code, and then run it in real time under monitor control.
89S8253 Microcontroller
The MICRO LAB-51 uses the 89S8253 microcontroller which is 8051 compatible and runs at up to 24 MHz. The chip contains 12K bytes of flash for program storage. A nice feature of the 89S8253 is that its flash can be programmed serially, so that no programmer is required. This also facilitates software upgrades, even after the board has been placed into an application.
Board Features
In addition to the 89S8253, there are two 28 pin memory sockets. The first supports 32K bytes of RAM, while the second supports 28K bytes of EEPROM, EPROM, or battery-backed RAM. Other board features include RS-232 serial port buffering ( RS-485 is optional ), processor supervisory circuit with manual reset switch, and an ample prototyping area. Data, address, and control lines are conveniently brought out on connectors next to the prototype area. As a result, adding custom user circuitry is a snap.
