Product details

36 Mbit synchronous SRAM — 167 MHz pipe, 3.4 ns access

The Cypress CY7C1440AV33-167AXCT is a 36 Mbit synchronous SDR SRAM organized as 1M × 36, clocked at 167 MHz with a 3.4 ns access time. It operates from a 3.135 V to 3.6 V supply and comes in a 100-TQFP (14×20 mm) surface-mount package. This is a single-data-rate (SDR) part — one data transfer per clock edge — suited for networking buffers, telecom line cards, and test equipment where deterministic read latency matters more than peak bandwidth.

Obsolete — sourcing through the independent channel

Commercial temperature — indoor equipment only

Not suitable for outdoor use.

Frequently asked questions

What is the closest pin-compatible alternative to CY7C1440AV33-167AXCT?

There is no direct pin-compatible drop-in from Cypress at the same 167 MHz clock and 36 Mbit density. The CY7C1440 family shares the 100-TQFP footprint across density options, so a board respin to a different density is possible if the memory controller supports it.

Where can I buy CY7C1440AV33-167AXCT and get current pricing?
