The Infineon CY7C1041G30-10ZSXET is a 4 Mbit asynchronous SRAM organized as 256K words by 16 bits. It delivers a 10 ns access time across -40°C to 125°C.
A 10 ns access time means the SRAM presents valid data within 10 ns of the address being stable.
The TSOP II package is a standard JEDEC outline.
The access time is 10 ns, and the write cycle time is also 10 ns.
The part is listed as RoHS compliant based on the 'E' suffix in the order code, which indicates lead-free and RoHS-compliant finish.
It comes in a 44-pin TSOP II (0.400 inch body width, 10.16 mm), surface-mount package, supplied in Tape & Reel.
Yes, the lifecycle stage is end-of-life (EOL). Infineon no longer manufactures this part, and it must be sourced from the independent surplus market.
No official replacement is listed by Infineon. For a pin-compatible alternative, search for 4 Mbit asynchronous SRAMs in 44-TSOP II with a 10 ns access time from ISSI, Alliance Memory, or Renesas — verify the supply voltage range and temperature grade match your BOM.
