Product overview
The UT8R2M39 is an 80 Mb CMOS static RAM multichip module organized as 2M × 39. It combines four SRAM die in a 132-lead ceramic quad flatpack and provides 22 ns read access with 10 ns write access. Active-low chip enables, output enable and three-state drivers support memory expansion and bus control. Its 39-bit-wide organization supports systems using external error-detection and correction logic. A deselected power-down mode reduces consumption while preserving stored data. Core and I/O supplies are separate, and the selected SMD ordering configuration defines radiation assurance, temperature range and quality level.
