CY7C09079V-12AC - Brand New Cypress Semiconductor IC Chips
-
Description
The CY7C09079V-12AC is an electronic component model in the product category of IC chips. It is a low-power CMOS dual-port static RAM with various arbitration schemes to handle situations when multiple processors access the same piece of data. It features true dual-ported memory cells, with available options for 4K x 16/18 or 8K x 16/18 organizations. The CY7C09079V-12AC operates at a high-speed access of 15 ns and low operating power of ICC = 150 mA (typ.). It supports fully asynchronous operation, automatic power-down, and expandable data bus to 32/36 bits or more when using more than one device. The CY7C09079V-12AC is available in 84-pin PLCC and 100-pin TQFP packages.
