Description

The LC321664AT is a CMOS dynamic RAM operating on a single 5 V power source and having a 65536-word × 16-bit configuration. Equipped with large capacity capabilities, high-speed transfer rates and low power dissipation, this series is suited for a wide variety of applications ranging from computer main memory and expansion memory to commercial equipment.

Address input utilizes a multiplexed address bus which permits it to be enclosed in compact plastic packages of SOJ 40-pin, SOP 40-pin and TSOP 44-pin. Refresh rates are within 4 ms with 256 row address (A0 to A7) selection and support RAS-only refresh, CAS-before-RAS refresh and hidden refresh settings.

There are functions such as page mode, read-modifywrite, and byte-write.
