Product details

10 ns asynchronous SRAM for legacy 5V bus architectures

The CY7C1046D-10VXIT is a 4Mbit asynchronous SRAM organized as 1M × 4 bits, with a 10 ns access time and a 4.5 V to 5.5 V supply range.

A 10 ns access time means the SRAM can complete a read or write cycle in 10 ns from address valid.

Frequently asked questions

What is the replacement for CY7C1046D-10VXIT?

Infineon has not published an official successor order code for the CY7C1046D-10VXIT. For a form-fit-function replacement, look for a 5 V, 10 ns, 1M × 4 asynchronous SRAM in a 32-SOJ package from another manufacturer — verify pin compatibility against the Cypress/Infineon datasheet before substituting. The CY7C1046D-10VXI is the same die in tube/tray packaging, not a functional replacement.

Is CY7C1046D-10VXIT pin compatible with CY7C1046D-10VXI?

Yes, the CY7C1046D-10VXI and CY7C1046D-10VXIT share the same die and 32-SOJ package. The only difference is the shipping format: the VXI variant ships in tube or tray, while the VXIT variant ships in Tape & Reel. Both are obsolete.

What is the operating temperature range of CY7C1046D-10VXIT?

The CY7C1046D-10VXIT is rated for an industrial operating temperature range of −40°C to 85°C (TA).
