4Mbit asynchronous SRAM for processor data buffers
The Infineon CY7C1041CV33-10BAXA is a 4 Mbit asynchronous SRAM organized as 256K words by 16 bits, with a 10 ns access time and a matching 10 ns write-cycle time — the bus timing is symmetric, so the memory controller's address-to-data valid window is the same for reads and writes. The parallel interface means no clock or serial protocol overhead — the processor asserts the address, strobes chip-enable and output-enable, and data appears on the bus within 10 ns. Lifecycle status is Active per the manufacturer — no NRND or EOL flags, so it remains eligible for new designs and production builds without last-time-buy risk.
48-ball FBGA footprint and reflow considerations
It is supplied in tray format, which means the pick-and-place feeder setup uses a tray shaker or waffle-pack handler — no tape-and-reel, so the placement cycle time is slower than a reel-fed part, and the tray must be kept in the dry cabinet if the MSL rating (not listed here) requires it. Bake the parts if the floor life is exceeded before reflow.
Sourcing and availability for production BOMs
The 4 Mbit x16 asynchronous SRAM market has few direct drop-in replacements — the footprint and timing are specific to this base product number. The tray quantity per shipment is lot-specific — quote the BOM line quantity to get the exact unit count and lead time.
