Product details

Synchronous FIFO — 18K buffer at 66.7 MHz

The CY7C4231V-15JXCT is a synchronous FIFO organized as 2K x 9 bits (18 Kbit total). It operates at a 66.7 MHz data rate with an 11 ns access time. The 9-bit width (8 data + 1 parity/control) suits it for buffering between busses or as a rate-matching buffer in telecom or imaging pipelines where a narrow word width and moderate depth are sufficient.

Supply, temperature, and package

Runs on a 3 V to 3.6 V core supply. Packaged in a 32-PLCC (J-Lead) with a body size of 11.43 x 13.97 mm. The J-Lead footprint requires a reflow profile compatible with PLCC solder joints; the tape-and-reel delivery suits automated pick-and-place.
