The Texas Instruments SMJ44400-12HRM is a 4 Megabit Fast Page DRAM with a memory organization of 1M x 4 bits. This component operates with a maximum access time of 120 ns and utilizes CMOS technology. It supports Fast Page mode with EDO (Extended Data Out) capabilities, along with CAS-before-RAS and hidden refresh functionality. The device features a common I/O type and 3-state outputs. Packaged in a 20-terminal ceramic, metal-sealed cofired flatpack (CDFP20, JESD-30 code R-CDFP-F20), it is designed for surface mounting. Operating temperature ranges from -55°C to 125°C with a supply voltage range of 4.5V to 5.5V. This component is suitable for demanding applications in aerospace, defense, and high-reliability industrial systems due to its extended temperature range and robust packaging.
