Texas Instruments SMJ44400 Fast Page DRAM, organized as 1Mx4 bits, offers an 80ns maximum access time. This CMOS component utilizes a CDSO20 package with a 1.27mm terminal pitch. Key operational features include RAS ONLY, CAS BEFORE RAS, and HIDDEN REFRESH modes, with 1024 refresh cycles supported. The I/O is COMMON with 3-state output characteristics. Operating from a 4.5V to 5.5V supply, the SMJ44400 series is designed for demanding applications requiring high-speed memory access. Its robust construction and wide operating temperature range from -55°C to 125°C make it suitable for aerospace, defense, and high-reliability industrial systems. The SMJ44400 is characterized by its ceramic, metal-sealed cofired package and J-bend terminals for surface mounting.
