Product details

256K x 16 asynchronous SRAM with 20 ns access

The Infineon (Cypress) CY7C1041CV33-20ZXC is a 4Mbit asynchronous SRAM organized as 256K words by 16 bits. It provides a 20 ns access time and a matching 20 ns write cycle time, making it suitable for moderate-speed data buffering, cache tag storage, or working memory in embedded systems that need a simple parallel memory interface without refresh overhead.

It is no longer in production from Infineon (Cypress). Procurement must go through surplus or broker channels.
