MSM82C37B-5RS/GS/VJS
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 mA (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
