The Texas Instruments SMJ417400-70HKBM is a 4M x 4 Fast Page Mode DRAM IC. This component offers a maximum access time of 70ns and operates using CMOS technology. It supports essential refresh modes including RAS Only, CAS Before RAS, and Hidden Refresh, with 2048 refresh cycles. The device is housed in a 28-lead Ceramic Flat Pack (CDFP) with a metal-sealed cofired package, designed for surface mounting with a 1.27mm terminal pitch. Operating across an industrial temperature range of -55°C to +125°C, it requires a supply voltage between 4.5V and 5.5V, with a nominal value of 5V. This memory component is suitable for applications in industrial, telecommunications, and military systems demanding high reliability and performance.
