Active production — no BOM-line risk
The CY7C1041CV33-10ZSXAT: For a procurement desk managing a long-running build, this part does not trigger the last-time-buy clock — no need to qualify an alternate solely on lifecycle grounds.
10 ns access — timing margin for the bus
Rated for a 10 ns access time and a matching 10 ns write-cycle time (word, page), this asynchronous SRAM delivers a 100 MHz equivalent read/write throughput in a parallel interface — the bus timing closure depends on the controller's output hold and setup relative to this window. The 4 Mbit density is organized as 256K x 16, which fits a 16-bit data bus without byte-lane gating — the address range maps directly into a 256K-word memory window.
44-TSOP II — footprint and sourcing
Housed in a 44-TSOP II (0.400-inch body width, 10.16 mm), the package uses a standard 0.8 mm pitch — the same footprint used by many 4 Mbit and 8 Mbit asynchronous SRAMs, so a board layout designed for one density often accepts the other without a respin. Supplied in Tape & Reel (TR) format, the part is ready for automated pick-and-place assembly — no manual handling required for volume production.
