Design of ADC/DAC card and Interfacing With 8085 MicroprocessorADCDAC
4.1 Interfacing 8080 Microprocessor Derivatives (8048, 8085) This converter has been designed to directly interface with derivatives of the 8080 microprocessor. The A/D can be mapped into memory space (using standard memory address decoding for CS and the MEMR and MEMW strobes) or it can be ...

The circuit of Figure 22 can again be used, with IO/M in place of IORQ for a memory-mapped interface, and an extra inverter (or the logic equivalent) to provide IO/M for an I/O-mapped connection. Interfacing 6800 Microprocessor Derivatives (6502, etc.) The control bus for the 6800 ...

MICROPROCESSOR INTERFACING The fast conversion times of the AD ADC84/AD ADC85 suggests several methods of interface to microprocessors. In systems where the ADC is used for high sampling rates on a single signal which is to be digitally processed, CPU-controlled conversion may be inefficien...
