The Infineon CY7C1049CV33-8ZSXC is a 4 Mbit asynchronous SRAM organized as 512K x 8 bits, with an 8 ns access time and a parallel interface. It operates from a 3 V to 3.6 V supply and is specified over the commercial temperature range of 0°C to 70°C. This part is typically used as a fast cache or scratchpad memory in embedded systems, networking equipment, or test instrumentation where deterministic read/write timing and no refresh overhead are required.
