DESCRIPTION
This simplifies external clock inputs, while providing the same simple, non-multiplexed pinout as industry standard SRAMs. Moreover, due to the functional similarities between PSRAMs and SRAMs, many 32K × 8 SRAM sockets can be filled with the LH5P832 with little or no changes. The advantage is the cost savings realized with the lower cost PSRAM. CMOS 256K (32K × 8) Pseudo-Static RAM The LH5P832 PSRAM has the ability to fill the gap between DRAM and SRAM by offering low cost, low standby power, and a simple interface. Three methods of refresh control are provided for maximum versatility.
