The Texas Instruments TMS4256-10FML is a 256K x 1 bit NMOS PAGE MODE DRAM with a maximum access time of 100ns. This component operates asynchronously and features separate I/O with 3-state output characteristics. Supported refresh modes include RAS ONLY, CAS BEFORE RAS, and HIDDEN REFRESH, with 256 refresh cycles required. The device is housed in an 18-terminal Plastic Quad Flat Chip Carrier (PQCC) package (JESD-30 Code: R-PQCC-J18) suitable for surface mounting. Its typical applications span industrial control, telecommunications infrastructure, and consumer electronics where reliable memory density and flexible access modes are critical. Operating voltage range is 4.5V to 5.5V, with a nominal supply of 5V. The operating temperature range is 0°C to 70°C.
