It clocks at 66.7 MHz with a 10 ns access time, making it suitable for rate-matching or short data queues in legacy 5 V systems. The part is uni-directional with depth and width expansion capability, and supports programmable flags but not retransmit or FWFT. ## PLCC-32 package and board integration Housed in a 32-lead PLCC (J-Lead) package with a body size of 11.43 x 13.97 mm (supplier device package 32-PLCC). The surface-mount footprint requires a reflow profile compatible with J-lead soldering — the J-bend leads have a lower standoff than gull-wing, so stencil thickness and paste volume should be adjusted to avoid solder bridging.","metaTitle":"CY7C4201-15JXCT Infineon FIFO, 2.25 Kbit, 66.7 MHz","metaDescription":"CY7C4201-15JXCT synchronous FIFO, 2.25 Kbit (256 x 9), 66.7 MHz data rate, 10 ns access time.
