Product details

That clock rate means data transfers on both edges of the clock, effectively doubling the data rate through the parallel interface. The memory is organized as 2M words by 18 bits — the 18-bit width is a natural fit for systems that carry a parity or ECC byte alongside a 16-bit data word, common in networking packet buffers and cache tag stores.

Temperature grade — indoor only

This part is intended for controlled environments — telecom central office, data-center line cards, test equipment — not for outdoor, under-hood, or unheated enclosures. If your BOM calls for industrial or automotive temperature, this is not the variant.

Package and board-level handling

The package is a 165-ball FBGA with a 13x15 mm body (supplier device package 165-FBGA).

For a production BOM line, this means no near-term obsolescence risk.

Frequently asked questions

What is the closest pin-compatible alternative to CY7C1423KV18-300BZXCT?

A direct speed-grade alternative within the same family is the CY7C1423KV18-250BZXCT, which runs at 250 MHz instead of 300 MHz. The pinout and package are identical, so it can serve as a drop-in replacement if the system timing budget allows the lower clock rate.
