This document introduces the features and characteristics of CY7C09349AV and CY7C09359AV two 3.3V 4K/8K x 18 Synchronous Dual-Port Static RAMs
This document provides a technical overview of the Cypress CY7C09349AV and CY7C09359AV synchronous dual-port static RAMs. These devices are high-speed 3.3V CMOS chips available in 4K x 18 and 8K x 18 organizations, respectively. They feature true dual-ported memory cells allowing simultaneous access to the same location via two independent ports.
| Organization (CY7C09349AV) | 4K x 18 |
|---|---|
| Organization (CY7C09359AV) | 8K x 18 |
| Operating Voltage | 3.3V |
| Max Access Time (Pipelined) | 9 ns / 12 ns |
