Product details

256Kbit asynchronous SRAM — 20 ns access, 5 V parallel bus

The Infineon CY7C199CN-20ZXI is a 256Kbit asynchronous SRAM organized as 32K x 8, with a 20 ns access time and a parallel interface. It operates from a 4.5 V to 5.5 V supply and is rated for the industrial temperature range of -40°C to 85°C. This part is suited for cache buffers, data logging, and microcontroller memory expansion in embedded systems where fast, volatile storage is needed.

This part is officially obsolete per Infineon's lifecycle status. There is no listed direct replacement from the manufacturer. Sourcing is through independent distribution — we can quote it to order against an RFQ.
