The Texas Instruments TMS44409-70DGA is a 4,194,304-bit EDO DRAM organized as 1Mx4 bits. This device features asynchronous operation with an access time of 70ns. It supports Fast Page Mode with EDO capabilities, offering enhanced performance over standard Fast Page Mode. Refresh modes include RAS-only, CAS-before-RAS, and hidden refresh cycles, with a standard 1024 refresh cycles requirement. The component utilizes MOS technology and is housed in a 20-lead Plastic Small Outline Thin Package (PDSO20) with a 1.27mm pitch. Operating voltage ranges from 4.5V to 5.5V nominal 5V, with a maximum operating temperature of 70°C. This memory device is suitable for applications in computing, networking, and industrial control systems.
