M5M82C37AP
M5M82C37AP is CMOS PROGRAMMABLE DMA CONTROLLER manufactured by Mitsubishi Electric.
DESCRIPTION
The M5M82C37AP is a programmable 4-channel DMA (Direct Memory Access) controller. This device is specially designed to simplify data transfer at high trasfer rate for microputer systems. Fabricated using the silicon-gate CMOS technology, the M5M82C37AP operates using a single 5V power supply.
FEATURES
- 5V single supply, single TTL clock
- Four channel DMA controls with priority DMA request acknowledge functions
- DMA enable/disable, automatic initialization enable/dis- able, address increment/decrement programmability for each cannel
- Programmable DREQ input and DACK output logic polarity
- Direct connecting permits easy DMA channel expansion.
- Memory to memory data transfer
- EOP input/output permits DMA operation pletion check as well as forcibly pleting DMA operation.
APPLICATION
- DMA control of peripheral equipment such as floppy diskettes and CRT terminals that require...
