Product details

This is a fast, wide-bus memory intended for cache, buffer, and scratchpad duty in embedded systems where the host controller — typically a 3.3 V MCU, DSP, or FPGA — needs single-cycle reads and writes without the latency of a synchronous burst interface. The 16-bit data width matches a single 16-bit host bus directly; a 32-bit host would pair two of these parts with a shared address bus.

The 3.0V to 3.6V supply range centres on 3.3 V, so the part works directly with 3.3 V logic families — no level shifters needed on the address, data, or control lines. Input and output levels are LVTTL-compatible, which covers the vast majority of 3.3 V MCUs, FPGAs, and application processors. The 10 ns write cycle time (word and page modes) matches the read access time, so back-to-back read-write sequences do not introduce dead cycles on a 100 MHz bus.

Package and layout

The Tape & Reel (TR) shipping medium is standard for automated pick-and-place assembly.

Frequently asked questions

Where can I buy CY7C1041CV33-10BAXAT?

Submit an RFQ to confirm current availability and pricing — stock and lead time are quoted to order, not published as a live number.

What is the access time of CY7C1041CV33-10BAXAT?

The access time is 10 ns for both read and write cycles (word and page modes), which supports bus operation up to 100 MHz with proper timing margins.

Can CY7C1041CV33-10BAXAT work with 3.3V microcontrollers?

Yes. The supply range is 3.0V to 3.6V, centred on 3.3 V, and the I/O levels are LVTTL-compatible, so it interfaces directly with 3.3 V logic without level translation.

What is the replacement for CY7C1041CV33-10BAXAT?

No official replacement has been announced — the part remains active. For a second source, Infineon's own CY7C1041CV33 series includes functionally identical speed and package variants; check the base product number CY7C1041 for alternate ordering options.
