Intel N21256-06 is a 256K x 1 bit Page Mode DRAM, operating at a maximum access time of 60ns. This MOS technology component features separate I/O and 3-state output characteristics. It supports multiple refresh modes including RAS ONLY, CAS BEFORE RAS, and HIDDEN REFRESH, with 256 refresh cycles. The device is housed in an 18-terminal PQCC (Plastic Quad Flat Pack) package (JESD30 Code R-PQCC-J18) with a terminal pitch of 1.270mm. Operating voltage ranges from 4.5V to 5.5V with a nominal 5V supply. Typical applications include general-purpose memory expansion in computing and embedded systems. The operating temperature range is 0°C to 70°C.
