The CY7C433-10AXC: Organized 4K words deep by 9 bits wide. 10 ns access time; 50 MHz data rate on a 9-bit bus.
Retransmit and expansion — design flexibility
Retransmit capability allows re-sending data from a marker point without a full reset. Depth and width expansion via cascade supports larger buffers.
Obsolete — sourcing through independent channels
Cypress has marked the CY7C433-10AXC obsolete. For new designs requiring a production-continuous FIFO, consider the current-generation Cypress (now Infineon) asynchronous FIFO family in the same 32-TQFP footprint — verify pin compatibility against the datasheet.
Suitable for indoor, temperature-controlled equipment.
