This part is designed for high-throughput buffering in networking equipment, base stations, and test instrumentation where deterministic read-write latency matters more than the burst efficiency of DDR SRAM. At 167 MHz the clock period is about 6 ns, so this access time leaves roughly 2.6 ns for board trace delay, input setup, and output hold — a tight but manageable margin for a well-terminated bus on a typical FR4 PCB. Designs that push trace lengths beyond 4 inches or use multiple loads on the same data bus should budget a derating simulation. ## Last Buy — plan the final order window For production builds that depend on this exact density and speed grade, the procurement strategy is to secure lifetime-buy quantities through the authorized channel or, after the LTB window closes, source from independent distribution against an RFQ. ## Package and footprint — 100-LQFP (14x20 mm) The supplier device package is 100-TQFP (14x20), which is the same footprint — TQFP and LQFP are thermally and dimensionally interchangeable for this body size.","metaTitle":"Infineon CY7C1382KV33-167AXC SRAM, 18Mbit, 167 MHz, 3.4 ns","metaDescription":"Infineon CY7C1382KV33-167AXC synchronous SDR SRAM, 18Mbit (1M x 18), 167 MHz clock, 3.4 ns access time, 3.135V-3.6V, 100-LQFP, 0°C to 70°C.","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":"-","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":"3.135V ~ 3.6V","Base Product Number":"CY7C1382","Memory Organization":"1M x 18","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"100-TQFP (14x20)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$32.6500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/044d67db0402b63df3a9fffdea56472d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1382KV33-167AXC/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for CY7C1382KV33-167AXC?","answer":"The Last Buy lifecycle means Infineon has not designated a direct pin-compatible successor for this density and speed grade.
