W26020A

W26020A 128K × 16 HIGH-SPEED CMOS STATIC RAM GENERAL DESCRIPTION The W26020A is a high-speed, low-power CMOS static RAM organized as 131,072 × 16 bits that operates on a single 5-volt power supply. This device is manufactured using Winbond's high performance CMOS technology. The W26020A has an active low chip select, separate upper and lower byte selects, and a fast output enable. No clock or refreshing is required. Separate byte select controls (LB and UB ) allow individual bytes to be written and read. LB controls I/O1-I/O8, the lower byte. UB controls I/O9− I/O16, the upper byte. This device is well suited for use in high-density, high-speed system applications. FEATURES High speed access time: 20/25 nS (max.) Low power consumption: − Active: 1.5W (max.) Single +5V power supply Fully static operation − No clock or refreshing All inputs and outputs directly TTL compatible Three-state outputs Data byte control − LB (I/O1−I/O8), UB (I/O9−I/O...
