80552 microcontrollerboard

For my preamplifier I developed a microcontroller-board, which can also be used for other projects. The main characteristic is the possibility to reprogram the program memory (flash) using the serial interface. The main features are:

• 80c552-controller
• 64 kB FLASH-ROM, 32 kB RAM
• in-circuit-programmable
• complete addresslogic in GAL
• 9 chipselect-signals for external memory-mapped-IO
• I²C-bus
• watchdogtimer, voltage-supervisor, backup-battery for RAM
• complete RS232-interface (MAX232)
• Compatible with the development enviroment of Wickenhäuser

This board has been published in the Elektor in january 2004. So the PCB can be ordered from Elektor (for very little money :-)
