Product details

66.7 MHz synchronous FIFO for 5 V logic buffers

The CY7C4201-15JXCT is a synchronous FIFO from the CY7C series, organized as 256 words by 9 bits (2.25 Kbit total). 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.

Frequently asked questions

What is the memory size and organization of CY7C4201-15JXCT?

The FIFO is organized as 256 words by 9 bits, for a total memory size of 2.25 Kbit. The 9-bit width allows storage of a data byte plus a parity or control bit.

What package does CY7C4201-15JXCT use?

It comes in a 32-lead PLCC (J-Lead) package, supplier device package 32-PLCC (11.43 x 13.97 mm body). The J-lead footprint is surface-mount and requires a reflow profile suited for J-bend leads.

What is the data rate and access time of CY7C4201-15JXCT?

The synchronous FIFO supports a 66.7 MHz clock rate with a 10 ns access time. This sets the maximum throughput for read/write cycles in a 5 V logic system.
