32 K × 8 Static RAM Features ■ High speed ❐ 15 ns ■ Fast tDOE ■ CMOS for optimum speed/power ■ Low active power ❐ 550 mW (max, 15 ns “L” version) ■ Low standby power ❐ 0.275 mW (max, “L” version) ■ 2 V data retention (“L” version only) ■ Easy memory expansion with CE and OE features ■ TTL-compatible inputs and outputs ■ Automatic power-down when deselected Logic Block Diagram CY7C199N 32 K × 8 Static RAM Functional Description The CY7C199N is a high-performance CMOS static RAM organized as 32,768 words by 8 bits. Easy memory expansion is provided by an active LOW Chip Enable (CE) and active LOW Output Enable (OE) and three-state drivers. This device has an automatic power-down feature, reducing the power consumption by 81% when deselected. The CY7C199N is in the standard 300-mil-wide DIP, SOJ, and LCC packages. An active LOW Write Enable signal (WE) controls the writing/reading operation of the memory. When CE and WE inputs are both LOW, data on t...
