The 25 ns access time means the memory can complete a read or write cycle within a single 40 MHz bus clock period, making it suitable for shared-buffer designs in telecom line cards, industrial controllers, and multiprocessor systems where two subsystems exchange data through a common SRAM mailbox. ## Obsolete — no official replacement on record Infineon lists the CY7C025-25AXI as Obsolete. There is no pin-compatible direct replacement from Infineon; a board-level redesign would be required to migrate to a different dual-port SRAM or a FIFO-based alternative. The industrial temperature range (-40°C to 85°C) means this part was originally qualified for factory-floor, outdoor telecom, and engine-compartment environments. If a replacement is needed for a new design, the temperature grade should be matched — many current dual-port SRAMs ship in commercial (0°C to 70°C) only. ## Package and board-fit — 100-LQFP with 14x14 mm body The CY7C025-25AXI comes in a 100-LQFP package with a 14x14 mm body (supplier device package 100-TQFP). The 0.5 mm pitch demands a controlled reflow profile — typical peak temperature for lead-free solder is 245-260°C, and the moisture sensitivity level (MSL) should be verified from the lot date code before reflow to avoid popcorn cracking. The tray packaging means the parts are shipped in antistatic trays, not tape-and-reel, which affects feeder setup on pick-and-place lines. Surface-mount mounting type — no through-hole variant exists for this order code. The 100-pin count with 0.5 mm pitch requires a 4-layer PCB minimum for fan-out of the address and data buses; two-layer boards will struggle to route all 16 data lines plus the control signals without via congestion.","metaTitle":"Infineon CY7C025-25AXI 128Kbit Dual-Port SRAM, 25ns","metaDescription":"CY7C025-25AXI dual-port asynchronous SRAM, 128Kbit (8Kx16), 25ns access time, 4.5-5.5V, 100-LQFP, -40°C to 85°C.
