The Texas Instruments SMJ44C256-15HKM is a 1Mbit CMOS Fast Page DRAM organized as 256K words by 4 bits. Featuring a 150ns maximum access time, this component supports the Fast Page mode with EDO for enhanced data throughput. The SMJ44C256 series offers CAS-before-RAS refresh functionality and operates with a common I/O type. Its 20-lead ceramic flatpack (CDFP20) package is designed for surface mounting and operates within a temperature range of -55°C to +125°C. This DRAM is suitable for applications requiring high-speed memory access in demanding environments, including aerospace, defense, and industrial systems. The device operates from a nominal 5V supply with a maximum tolerance of 5.5V.
