Product details

The P82C37A5 is a 4-channel DMA controller from the 82C37A-5 series, operating at 5 MHz. It handles memory-to-I/O and memory-to-memory data transfers without CPU intervention, a staple in legacy x86 ISA-bus systems and embedded designs that need fast block moves. The 40-pin DIP package (40-PDIP) fits through-hole boards still in service or being replicated for long-life industrial equipment.

5V-only supply — plan the rail

The 10 mA supply current is modest.

Commercial temperature — indoor use only

Not for unheated telecom cabinets or engine-bay electronics.

Frequently asked questions

What is the datasheet for P82C37A5?

The P82C37A5 is a 4-channel DMA controller from the 82C37A-5 series. The datasheet covers pinout, timing diagrams, and programming model for the 40-DIP package. Request it with your RFQ.

What is the power consumption of P82C37A5?

Supply current is 10 mA typical at 5 V, so power draw sits around 50 mW. No heatsink needed in normal indoor use.
