Product details

The CY7C1041BNV33L-15ZXC: The 15 ns access time on this 4 Mbit asynchronous SRAM means the part can complete a random read or write cycle in 15 ns.

256K x 16 organization — fit check

The 256K x 16 organization (4 Mbit total) is a standard density for 16-bit-wide data buses in older embedded systems — think TI TMS320C54x DSPs, PowerQUICC II network processors, or Xilinx Spartan-II FPGA block RAM expansion. The 44-TSOP II footprint is common across multiple vendors, so a board designed for this part can often accept an ISSI or Alliance Memory equivalent with no layout change, provided the timing and supply match.

Not rated for industrial enclosures, outdoor cabinets, or automotive under-hood.

Frequently asked questions

What is the closest pin-compatible alternative to CY7C1041BNV33L-15ZXC?

The ISSI IS61LV25616AL-15TLI is a pin-compatible drop-in with the same 256K x 16 organization, 15 ns access time, 44-TSOP II package, and 3.3 V supply. Verify the industrial temperature range (-40°C to 85°C) against your BOM before substituting.

What package does CY7C1041BNV33L-15ZXC come in?

It ships in a 44-TSOP II (0.400", 10.16 mm width) surface-mount package, supplied in Tray packaging.
