10 ns asynchronous SRAM for 5V bus systems
The Infineon CY7C1041G-10VXIT is a 4 Mbit asynchronous SRAM organized as 256K x 16 bits, with a 10 ns access time and a parallel interface. It operates from a 4.5 V to 5.5 V supply and is rated for -40°C to +85°C.
10 ns access time — what it buys the bus
A 10 ns access time means the SRAM can complete a read or write cycle in 10 ns. The 10 ns write cycle time is symmetric, so back-to-back writes at full speed are possible.
Industrial temperature grade and package
The -40°C to +85°C rating covers outdoor telecom cabinets, factory-floor controllers, and engine-bay electronics where commercial-grade parts drift out of spec. The 44-SOJ package is a surface-mount J-bend footprint that fits the same PCB land pattern as many legacy 44-pin PLCC sockets — useful for retrofitting an older board without a layout change. The part is supplied on Tape & Reel (TR) or Cut Tape (CT), so it feeds into standard pick-and-place lines.
