Texas Instruments SMJ44100-12HJM is a 4M x 1 Fast Page Mode DRAM, offering a memory density of 4,194,304 bits. This CMOS component operates with a maximum access time of 120ns and features separate I/O. Key operational modes include RAS-only, CAS-before-RAS, and hidden refresh, supporting 1024 refresh cycles. The SMJ44100 series device is housed in a 20-terminal ceramic, metal-sealed cofired small outline J-lead (SOJ) package, suitable for surface mounting. It requires a supply voltage ranging from 4.5V to 5.5V, with a nominal 5V. This component is designed for demanding applications requiring robust performance across an extended temperature range of -55°C to 125°C and meets MIL-PRF-38535Q/M, 38534H, and 883B screening levels. Applications include defense, aerospace, and industrial systems.
