Its two independent ports allow simultaneous read/write access from two bus masters — typically a microcontroller and a DSP, or two processors sharing a mailbox or data buffer. The 25 ns access time means each port can complete a read or write cycle within 25 ns, which at 5 V translates to a 40 MHz equivalent bus rate for back-to-back accesses, provided the arbitration logic handles contention on the same address. A 25 ns access time places this part in the fast-async SRAM tier. For a shared-memory design running at 25 MHz or below, the CY7C146-25JC meets a single-cycle read without wait states on most 8-bit or 16-bit buses. At higher clock rates the bus controller must insert one wait state per access. Supplied in a 52-lead PLCC with J-leads (52-LCC), the package body measures 19.13 mm square. The J-lead form factor is surface-mount but requires a PLCC socket or a footprint with the correct pad geometry — not a direct match for SOIC or QFP land patterns. The CY7C146-25JC is marked obsolete. No last-time-buy date or successor part number appears in the record. For production or repair requiring this exact order code, procurement goes through the independent distribution channel — stock is sourced from surplus inventory, verified for authenticity and date-code freshness. There is no factory-authorized alternate; a pin-compatible drop-in from another vendor would need to be qualified on the board.","metaTitle":"CY7C146-25JC Cypress 16Kbit Dual-Port SRAM, 25 ns, 52-PLCC","metaDescription":"CY7C146-25JC Cypress 16Kbit (2K x 8) asynchronous dual-port SRAM, 25 ns access time, 4.5V-5.5V supply, 52-PLCC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tube","Technology":"SRAM - Dual Port, Asynchronous","Access Time":"25 ns","Memory Size":"16Kbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"52-LCC (J-Lead)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"CY7C146","Memory Organization":"2K 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/633d0d1db57808705bb6b9d46e860437.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for CY7C146-25JC?","answer":"No official replacement part number is recorded for the CY7C146-25JC.
