Additional Details

The IS61C64AH-25N is a fully static memory, meaning that it does not require any refresh cycles to retain data. This simplifies the memory control circuitry and improves performance. The device typically supports separate data input and output lines for improved data throughput. It features a chip enable (CE) input to select the device and an output enable (OE) input to control the data output. The write enable (WE) input controls the write operation. This SRAM is suitable for applications where data is frequently accessed and modified. Its high speed and low power characteristics make it ideal for use as cache memory in microprocessor systems and for other performance-critical applications. The specific package type (e.g., DIP, SOJ, TSOP) will influence the pinout and physical dimensions of the device.
