The parallel interface and 2.5 V supply (2.375 V to 2.625 V) match the I/O voltage of many ASICs and FPGAs from that era, so it drops into an existing 2.5 V memory bus without level shifters. It comes in a 100-TQFP (14x20 mm) package, surface-mount, and is rated for commercial temperature operation (0°C to 70°C). ## Clock speed and access time — the throughput story The NoBL architecture eliminates the turnaround cycle between read and write, so a controller can issue a read on one clock and a write on the next without inserting an idle cycle. For a system running a 166 MHz memory controller, that means sustained throughput close to the theoretical bus limit — no dead cycles eating into the bandwidth budget. Cypress has placed the CY7C1370KV25-167AXC into Last Buy status. That means the manufacturer has announced end-of-life and is taking final orders before the part goes permanently out of production. If this SRAM is on your active BOM, you need to secure lifetime-buy quantities now or plan a migration to a successor. There is no official replacement listed in the available records, so the only channel going forward will be independent distribution — surplus and new-old-stock inventory sourced through brokers. The 100-TQFP (14x20 mm) is a garden-variety fine-pitch QFP. Pin count is 100, pitch is 0.5 mm typical for this body size. No exposed pad, so rework with a hot-air station is straightforward — no BGA underfill or reball to worry about. If you are swapping this on a board in a repair bay, a standard QFP stencil and a hot-air pencil will do the job.","metaTitle":"Cypress CY7C1370KV25-167AXC 18Mbit NoBL SRAM, 167 MHz","metaDescription":"Cypress CY7C1370KV25-167AXC 18Mbit synchronous SRAM (512K x 36), 167 MHz clock, 3.4 ns access.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"NoBL™","Package":"Tray","Technology":"SRAM - Synchronous, SDR","Access Time":"3.4 ns","Memory Size":"18Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Last Time Buy","Clock Frequency":"167 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"2.375V ~ 2.625V","Base Product Number":"CY7C1370","Memory Organization":"512K x 36","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"100-TQFP (14x20)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$25.3447","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c106f2e723425f5cd518180bec066d38.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1370KV25-167AXC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1370KV25-167AXC obsolete?","answer":"The CY7C1370KV25-167AXC carries a Last Buy lifecycle status from Cypress, meaning the manufacturer has announced end-of-life and final orders are being accepted.
