Texas Instruments TMS48C121-80DZ is a 1Mbit (128K x 8) CMOS Video DRAM. This component features an 80ns access time, supporting Fast Page Mode operation. It offers multiple refresh modes, including RAS Only, CAS Before RAS, and Hidden Refresh, alongside a 256 x 8 SAM port for enhanced functionality. Designed for surface mounting, it is housed in a 40-lead SOIC (Small Outline Integrated Circuit) package with a J-bend terminal form and 1.27mm pitch. Operating within a 4.5V to 5.5V supply voltage range, the TMS48C121-80DZ is suitable for applications requiring high-speed video memory, often found in display controllers, graphics accelerators, and embedded systems. The operating temperature range is 0°C to 70°C.
