Intel P21256-07 is a 256K x 1 bit Page Mode DRAM, offering a 70ns maximum access time. This MOS technology component features separate I/O and operates asynchronously. Supporting RAS ONLY, CAS BEFORE RAS, and HIDDEN REFRESH modes, it provides flexibility in memory management. The device is housed in a 16-pin PDIP package (R-PDIP-T16) with through-hole termination. Typical applications include industrial control and legacy system designs where high-speed, cost-effective memory is required. The P21256 series is known for its robust performance in demanding environments.
