The Texas Instruments TMS427400-70DGA is a 16,777,216-bit (4M x 4) Fast Page Mode Dynamic Random Access Memory (DRAM) IC. This component features a maximum access time of 70 ns and operates using CMOS technology. The memory organization is 4M words by 4 bits, providing a 4-bit data width. Supporting Fast Page Mode, it also incorporates RAS-only, CAS-before-RAS, and Hidden refresh modes, with 2048 refresh cycles. The device utilizes a common I/O type and operates asynchronously. It is housed in an R-PDSO-G24 (TSOP2) package, a 24-terminal rectangular plastic/epoxy surface-mount device with a terminal pitch of 1.27 mm. Operating voltage ranges from 3.0 V to 3.6 V with a nominal value of 3.3 V. This memory component finds application in various consumer electronics, industrial control systems, and telecommunications equipment.
