Texas Instruments TMS46400 Fast Page DRAM offers 4Mbit density with a 1Mx4 organization, featuring an 80ns maximum access time. This CMOS component operates asynchronously and supports Fast Page mode, RAS Only, CAS Before RAS, and Hidden Refresh modes. It is housed in a 20-terminal Small Outline J-Lead (SOJ) package with a 1.27mm pitch, suitable for surface-mount applications. The J-Lead terminal form ensures robust solder joints. Operating from a 3.0V to 3.6V supply, it exhibits a standby current of 300µA maximum and a supply current of 50mA maximum. Applications span consumer electronics, telecommunications, and industrial control systems requiring high-speed memory solutions.
