A 25 ns access time means the SRAM can complete a read or write cycle in 25 ns from address valid, which translates to a 40 MHz maximum bus frequency in zero-wait-state designs. For a shared-memory link between two processors or an FPGA and a microcontroller, this timing leaves roughly 10–15 ns of margin after accounting for PCB trace delay and output hold times at 5V logic levels — enough for most through-hole or PLCC-based layouts without needing series termination. ## 52-PLCC J-lead — rework and footprint notes The 52-PLCC (19.13 x 19.13 mm) J-lead package is a surface-mount part that can be hand-soldered or reflowed, but the J-lead geometry makes visual inspection of the solder joint tricky — you are trusting the fillet. The J-lead footprint is the same as a standard 52-PLCC socket, so a socketed prototype is an option if you are still debugging. No direct pin-compatible replacement has been announced; the dual-port SRAM market has largely moved to higher-density synchronous parts or integrated dual-port blocks in FPGAs.","metaTitle":"CY7C141-25JC Cypress 8Kbit Dual-Port SRAM, 25 ns, 52-PLCC","metaDescription":"CY7C141-25JC Cypress dual-port asynchronous SRAM, 8Kbit (1K x 8), 25 ns access time, 4.5–5.5V, 52-PLCC, 0°C–70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"title":"CY7C141-25JC","Package":"Tube","Technology":"SRAM - Dual Port, Asynchronous","Access Time":"25 ns","Memory Size":"8Kbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"52-LCC (J-Lead)","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"CY7C141","Memory Organization":"1K x 8","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"52-PLCC (19.13x19.13)","Write Cycle Time - Word, Page":"25ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5e48d5d1639fa3e2218458e8b2f4315c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for CY7C141-25JC?","answer":"There is no direct pin-compatible replacement announced by Cypress/Infineon.
