It clocks at 100 MHz, giving an 8 ns access time — the cycle time matches the clock period, so the read pointer advances on every rising edge without wait states. ## 32-PLCC footprint and board-fit Housed in a 32-lead PLCC (J-lead) package with a body size of 11.43 x 13.97 mm, the part mounts on the board surface and reflows with standard JEDEC profiles. The J-lead gull-wing alternative — the PLCC footprint is larger than a TQFP but offers better visual inspection of solder joints under the J-bend. ## Obsolete — last-time-buy window closed No pin-compatible drop-in replacement from Infineon is documented.","metaTitle":"Infineon CY7C4421-10JXC synchronous FIFO, 576 x 9, 100 MHz","metaDescription":"Infineon CY7C4421-10JXC synchronous FIFO, 576 (64 x 9) memory, 100 MHz data rate, 8 ns access time, 32-PLCC.
