W24257AK-20

W24257AK-20: 32k x 8-Bit (256-Kilobit) High-Speed CMOS Static RAM IC, featuring a rapid 20-nanosecond random access time. Operating from a standard 5V logic supply rail, it balances an optimized low-power standby mode with accelerated write-strobe performance loops, making it ideal for high-frequency microprocessor cache memory and digital pulse-shaping registers, housed in a standard 28-pin skin through-hole plastic skinny-DIP (300-mil) package layout.
