Additional Details

The LP621024DM-55LLF is a synchronous SRAM, implying standard asynchronous read and write cycles. The 'DM' in the part number may indicate specific features or packaging details, usually present in the datasheet. Its supply current consumption is important for low power usage calculations, specified by the operating and standby current values. Proper decoupling capacitors are recommended close to the power pins for stable operation and to minimize noise. The 55ns access time is the maximum time it takes for the SRAM to provide valid data after an address is applied. The datasheet provides detailed specifications, including timing diagrams, voltage levels, and temperature ranges. Newer systems often utilize faster and higher-density memory technologies, but SRAM remains valuable for applications requiring speed and simplicity.
