Intel Z21256 Series 256K x 1 Page Mode DRAM, part number Z21256-07, offers a 70ns access time and operates with MOS technology. This component features separate input/output, a 16-pin Plastic In-line Package (PZIP16), and supports various refresh modes including RAS ONLY, CAS BEFORE RAS, and HIDDEN REFRESH. The Z21256-07 is designed for asynchronous operation with a nominal supply voltage of 5V, ±10% tolerance, and a maximum supply current of 70mA. Its memory organization is 256K words by 1 bit, providing a total memory density of 262,144 bits. This device is suitable for applications in computing and telecommunications where efficient memory access and established DRAM technology are required. The through-hole, zig-zag in-line package facilitates straightforward board assembly.
