Product details

The CY7C433-10JXCT is an asynchronous FIFO memory organized 4K x 9 (36K total), with a 50 MHz data rate and 10 ns access time.

Obsolete — sourcing reality for the CY7C433-10JXCT

The CY7C433-10JXCT is marked obsolete by Cypress. For a BOM line that requires this exact part, the only channel is the independent surplus and broker market. Given the age of the part, verify date-code freshness and storage conditions on any lot offered; PLCC J-Lead packages can suffer from bent leads if handled in bulk reels.

Frequently asked questions

What is the replacement for CY7C433-10JXCT?

No official replacement or pin-compatible alternate is listed by Cypress for the CY7C433-10JXCT. If you need a drop-in replacement, verify the pinout and timing against other 32-PLCC async FIFOs, but expect that a redesign or adapter board may be required.

What are the exact specifications of CY7C433-10JXCT?

The CY7C433-10JXCT is a 36K (4K x 9) asynchronous FIFO with a 50 MHz data rate, 10 ns access time, 4.5 V to 5.5 V supply, 85 mA maximum supply current, retransmit capability, depth and width expansion, and a 32-PLCC J-Lead package. It operates from 0°C to 70°C.
