D43256AC-12L 32K × 8 Static RAM SRAM 120ns IC – DIP-28

The D43256AC-12L is a 32,768-word by 8-bit static CMOS RAM designed for fast, stable memory storage without the need for refresh cycles. It uses CMOS peripheral circuits and N-channel memory cells, which helps keep power consumption low while maintaining reliable operation. The device is built for systems that need simple, direct memory access and steady performance.

This SRAM is intended for applications where quick read and write behavior matters, and where a compact 28-pin DIP package is preferred. The datasheet highlights its fully static operation, 5V supply requirement, and data retention capability at very low voltage, making it practical for digital designs that need dependable memory support.

With a 120ns access-time version available in the ordering list, the D43256AC-12L fits well into designs that need a balance of speed, simplicity, and low standby power. Its straightforward control pins and common I/O structure also make it easy to integrate into a wide range of embedded and general-purpose electronic systems.
