The Texas Instruments SMJ44100-80HJM is a 4M x 1 FAST PAGE DRAM with an asynchronous operating mode and an 80ns maximum access time. This CMOS device features separate I/O and a 20-terminal CDSO20 package (JESD30 code R-CDSO-J20). Supported access modes include FAST PAGE, RAS ONLY, and CAS BEFORE RAS, along with HIDDEN REFRESH capabilities. It operates across a wide temperature range of -55°C to +125°C with a nominal supply voltage of 5V (4.5V to 5.5V range). This surface-mount component utilizes a ceramic, metal-sealed cofired package with a J-bend terminal form. Applications include high-reliability systems and defense sectors requiring robust memory solutions.
