4M-bit asynchronous SRAM chip with 512K x 8 organization, featuring a 55ns maximum access time. This surface-mount component utilizes a 32-pin STSOP package with a 0.5mm pin pitch and gull-wing leads. Operating from a 5V supply voltage (4.5V-5.5V range), it offers a 19-bit address bus and a maximum operating current of 60mA. Designed for a temperature range of -40°C to 85°C, the plastic package measures 8mm x 11.8mm x 1mm.
