Product details

256 Kbit asynchronous SRAM — 15 ns access time

The Infineon CY7C199C-15ZXCT is a 256 Kbit asynchronous SRAM organised as 32K x 8 bits, with a 15 ns access time and a parallel memory interface. It operates from a 4.5 V to 5.5 V supply and is specified over the commercial temperature range of 0°C to 70°C. This part is suited for cache, buffer, or scratchpad memory in legacy embedded systems, telecom line cards, and test equipment that require fast, simple SRAM without refresh overhead.
