Product details

Synchronous FIFO for 3.3 V data buffering

The CY7C4231V-25AXC is a synchronous FIFO with 18K (2K x 9) capacity, 40 MHz data rate, and 15 ns access time.

The 40 MHz data rate supports 40 million 9-bit words per second. The 15 ns access time is the window from read clock to data valid.

The 32-TQFP (7x7 mm) package is a surface-mount footprint. Supply current is 20 mA max.

Frequently asked questions

What is the replacement for CY7C4231V-25AXC?

No official pin-compatible replacement is listed by Cypress/Infineon. For new designs, evaluate the active CY7C42xxV synchronous FIFO family in 32-TQFP with 3.3 V supply, but confirm depth and flag support against your firmware requirements.

What is the access time of CY7C4231V-25AXC?

The access time is 15 ns from read clock to data valid.

What is the package type of CY7C4231V-25AXC?

The package is a 32-TQFP (7x7 mm), surface mount.
