Additional Details

The UM6164BK-20 is typically packaged in a 28-pin DIP (Dual In-line Package). It operates from a single +5V power supply. Chip Select (CS), Output Enable (OE), and Write Enable (WE) pins control the memory's operation. The device is ideally suited for applications requiring quick data access with a manageable memory footprint and no refresh requirements. It provides a cost-effective memory solution for embedded designs. Its low power operation allows it to be used in battery powered applications. The static nature means there's no need for complex refresh schemes, making it easy to design with.
