It provides two independent ports with separate address, data, and control lines, allowing simultaneous, independent reads and writes to any memory location — a key feature for shared-memory designs in multiprocessor systems, FIFO buffers, or communication bridges where two buses need to exchange data without arbitration overhead. The 25 ns access time sets the cycle budget for both ports. In a typical shared-memory application, the address-to-data valid window must accommodate the memory's access plus the bus driver propagation delays. At 25 ns, this part keeps up with 40 MHz-class controllers without wait states, but a 33 MHz or slower bus leaves comfortable margin. If your system clock exceeds 40 MHz or you need back-to-back reads on the same port, you'll want a faster grade — but for the majority of 16-bit dual-port applications from the 2000s era, this timing is the sweet spot. No last-time-buy window remains; the official channel no longer stocks it. ## 100-pin TQFP — footprint and reflow notes The part comes in a 100-pin LQFP (also specified as 100-TQFP, 14x14 mm body, 0.5 mm pitch). This is a fine-pitch QFP that demands careful solder-paste stencil alignment and a controlled reflow profile — no exposed pad, so all thermal dissipation goes through the leads. If the tape has been open longer than that, bake it at 125°C for 24 hours before reflow or risk popcorning.","metaTitle":"CY7C024E-25AXCT 64Kbit Dual-Port SRAM, 25 ns, 100-TQFP","metaDescription":"Infineon (Cypress) CY7C024E-25AXCT 64Kbit dual-port asynchronous SRAM, 4K x 16, 25 ns access, 5V supply, 100-TQFP.
