Product details

Infineon (formerly Cypress Semiconductor) has marked the CY7C1444AV33-167AXC as obsolete. This is a 36 Mbit synchronous SRAM organized 1M x 36, clocked at 167 MHz with a 3.4 ns access time, in a 100-LQFP package.

167 MHz clock, 3.4 ns access — timing budget fit

The 167 MHz clock rate and 3.4 ns access time define the bus timing for this synchronous pipeline SRAM. The 1M x 36 organization gives a 36-bit wide data bus.

Package and footprint — 100-LQFP (14x20 mm)

Housed in a 100-lead LQFP with a 14x20 mm body. This is a surface-mount, fine-pitch QFP.

Frequently asked questions

What is the replacement for CY7C1444AV33-167AXC?

Infineon has not published a direct replacement order code for this obsolete SRAM. A functionally similar synchronous SRAM with 1M x 36 organization, 167 MHz clock, and 100-LQFP package would be the starting point for a cross — but pin compatibility must be verified from the respective datasheets, as no official cross-reference exists.
