MSM82C37B-5RS/GS/VJS
Previous version: Aug. 1996
GENERAL DESCRIPTION
The MSM82C37B-5RS/GS/VJS,DMA (Direct Memory Access) controller is capable of high-
speed data transfer without CPU intervention and is used as a peripheral device in microcomputer
systems. The device features four independent programmable DMA channels.
Due to the use of silicon gate CMOS technology, standby current is 10
m
A (max.), and power
consumption is as low as 10 mA (max.) when a 5 MHz clock is generated.
All items of AC characteristics are compatible with intel 8237A-5.
FEATURES
Maximum operating frequency of 5 MHz (Vcc=5 V
±
10%)
High-speed operation at very low power consumption due to silicon gate CMOS technology
Wide operating temperature range from –40
°
C to +85
°
C
4-channels independent DMA control
DMA request masking and programming
DMA request priority function
DREQ and DACK input/output logic inversion
DMA address increment/decrement selection
Memory-to-Memory Transfers
Channel extension by cascade connection
DMA transfer termination by EOP input
Intel 8237A-5 compatibility
