256K x 8 asynchronous SRAM for byte-wide buses
The Infineon CY7C1010DV33-10ZSXI is a 2 Mbit asynchronous SRAM organized as 256K x 8 bits, with a 10 ns access time and a parallel interface. It operates from a 3V to 3.6V supply and is rated over the industrial temperature range of -40°C to 85°C. Packaged in a 44-TSOP II (10.16 mm width) surface-mount package, it is intended for use in embedded systems requiring fast, byte-wide scratchpad memory — typical applications include networking equipment, industrial controllers, and test instrumentation where deterministic read/write latency matters more than density.
256K x 8 organization — why it matters for your BOM
The byte-wide (x8) organization maps directly to the data bus of an 8-bit microcontroller or an FPGA with byte-enable lanes.
The 3V to 3.6V supply range runs from a standard 3.3V rail.
