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.","metaTitle":"Cypress CY7C433-10AXC Asynchronous FIFO, 4Kx9, 10ns, 32-TQFP","metaDescription":"Cypress CY7C433-10AXC asynchronous 4Kx9 FIFO memory, 10ns access time, 50MHz data rate, 4.5-5.5V, 0-70°C.
