Depth- and width-expansion capability is built in, and programmable flags are supported, but it does not offer retransmit or FWFT (First Word Fall Through) operation. The 32-TQFP package (7x7 mm) is surface-mount, intended for commercial-temperature (0°C to 70°C) equipment such as telecom line cards, network switches, and printer controllers where a moderate-depth synchronous buffer is needed. No direct pin-compatible replacement is listed in the Cypress portfolio; the 4K x 9 synchronous FIFO architecture with 40 MHz operation at 3.3 V is a niche that newer parts in the CY7C or IDT72V series may cover with different package or timing. For ongoing production, a last-time-buy or surplus-channel procurement is the practical path. ## 40 MHz synchronous — bus timing and flag support The 40 MHz clock rate and 15 ns access time mean the FIFO can sustain a back-to-back read or write every 25 ns cycle. The synchronous interface simplifies control in FPGA or ASIC designs: a single rising edge clocks data in or out, with almost-full and almost-empty flags available for flow control. Depth-expansion mode allows cascading multiple devices when 4K words are insufficient, though the lack of FWFT adds a dead cycle on the first read after a write-to-read transition — something to budget for in latency-sensitive paths.","metaTitle":"Cypress CY7C4241V-25AXC 36K Synchronous FIFO, 40 MHz, 15 ns","metaDescription":"Cypress CY7C4241V-25AXC synchronous FIFO: 36K (4K x 9), 40 MHz data rate, 15 ns access, 3.0–3.6 V supply, 32-TQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"CY7C","Package":"Tray","Function":"Synchronous","Data Rate":"40MHz","Access Time":"15ns","Memory Size":"36K (4K x 9)","FWFT Support":"No","Mounting Type":"Surface Mount","Expansion Type":"Depth, Width","Package / Case":"32-TQFP","Product Status":"Obsolete","Bus Directional":"Uni-Directional","lifecycle_stage":"eol_hot","Voltage - Supply":"3 V ~ 3.6 V","Base Product Number":"7C4241","Operating Temperature":"0°C~70°C","Retransmit Capability":"No","Current - Supply (Max)":"20mA","Supplier Device Package":"32-TQFP (7x7)","Programmable Flags Support":"Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/06df22868d8a34fd15e9034e48ed2c13.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy CY7C4241V-25AXC?","answer":"We source the CY7C4241V-25AXC to order through independent distribution.
