Project Info
Idea behind this system is highly simplified system. For that reason there is almost nothing on extension board and all 53 ports are available for user (only connectors, XTAL and EEPROM are present). Because of lack of HF-10060 programming interface it is expected that microprocessor module will be programmed in HF-6128 system.
System features:
53 I/O pins available as external ports
3 I/O pins for extension board resources
EEPROM 24C16 (DRIVE2)
XTAL
Protection against reversed supply polarity
Usage:
HF-6169 will be used in various projects for prototyping. At least:
HF-28100
HF-4001
HF-61250
Automatic motherboard recognision system
Systems HF-6169 and HF-6128 are first systems where automatic recognision of main board by microprocessor module are introduced. Thus microprocessor modules HF-12268 and HF-12269 can read digital signatures from EEPROM (DRIVE2) of extension boards HF-60268 and HF-60269 and apply "BIOS" software specific to hardware on these boards. This system will be introduced also in other systems with multiple microprocessor modules and motherboards.
