Texas Instruments TMS426800 series Fast Page DRAM, part number TMS426800-70DZ, offers a 16 Mbit (2M x 8) memory organization with a maximum access time of 70ns. This component operates using CMOS technology and supports Fast Page mode for efficient data transfer. Key operational features include RAS Only, CAS Before RAS, and Hidden Refresh for dynamic memory management. The device is housed in a 28-lead SOJ (Small Outline J-Lead) plastic package with J-bend terminals on a 1.27mm pitch, suitable for surface mounting. Operating within a temperature range of 0°C to 70°C, it requires a supply voltage between 3.0V and 3.6V, with a nominal 3.3V. This memory solution is commonly utilized in telecommunications, industrial control, and consumer electronics applications requiring high-speed data buffering.
