Product details

Synchronous FIFO for 3.3 V data buffering

The CY7C4201V-15AC is a synchronous FIFO organized as 256 words by 9 bits, 2.25 Kbit total. It operates at 66.7 MHz with 11 ns access time from a 3 V to 3.6 V supply.

66.7 MHz clock and 11 ns access — timing margin matters

The 66.7 MHz clock and 11 ns access time define the read/write cycle. The 11 ns access ensures data appears on the output bus within one clock cycle of read enable.

Obsolete — last-time-buy and surplus sourcing

The CY7C4201V-15AC is obsolete per the manufacturer's product status. No direct pin-compatible replacement is listed in the active portfolio.

Frequently asked questions

What is the replacement for CY7C4201V-15AC?

There is no direct pin-compatible replacement listed in the Cypress/Infineon active portfolio. For new designs, evaluate a current-generation synchronous FIFO such as the IDT72V series or a dual-port SRAM with FIFO emulation, but verify pinout and timing compatibility.

What is the access time of CY7C4201V-15AC?

The access time is 11 ns, and the maximum data rate is 66.7 MHz.

Can I use CY7C4201V-15AC in 3.3 V systems?

Yes, the supply range is 3 V to 3.6 V, making it directly compatible with 3.3 V logic without level translation.
