IC11B Single Board Computer with MC68HC11, 2MHz

Cheque-Card-sized HC11 Computer

In typical micro controller applications, one finds always the same components: CPU, RAM, EPROM, RTC, battery, EEPROM, timer system as well as parallel and serial interfaces. To avoid the need of designing this "computer core" again and again, the piggyback board IC11B was developed. IC11B is cheque-card-sized and has two rows of "IC-pins". Using such a standard unit in a design usually saves time and money.

The heart of the IC11B is the 8Bit CPU MC68HC11A1 from Motorola. For reliability reasons the board is built in four layers. The address decoder is built with HCT components for low-power consumption. All important signals are led to the "IC-pins".

Programs generated on the PC can be downloaded to the IC11B. During program development a battery-buffered RAM is used instead of the EPROM. Programs are thus translated for the "correct" addresses and tested in RAM, saving the need for an ERPOM-simulator.
