It operates at a 66.7 MHz data rate with an 11 ns access time. The 9-bit width (8 data + 1 parity/control) suits it for buffering between busses or as a rate-matching buffer in telecom or imaging pipelines where a narrow word width and moderate depth are sufficient. ## Supply, temperature, and package Runs on a 3 V to 3.6 V core supply. Packaged in a 32-PLCC (J-Lead) with a body size of 11.43 x 13.97 mm. The J-Lead footprint requires a reflow profile compatible with PLCC solder joints; the tape-and-reel delivery suits automated pick-and-place.","metaTitle":"CY7C4231V-15JXCT Infineon FIFO, 18K (2K x 9), 66.7 MHz","metaDescription":"CY7C4231V-15JXCT synchronous FIFO, 18K (2K x 9), 66.7 MHz data rate, 11 ns access time.","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":"Tape & Reel (TR)","Function":"Synchronous","Data Rate":"66.7MHz","Access Time":"11ns","Memory Size":"18K (2K x 9)","FWFT Support":"No","Mounting Type":"Surface Mount","Expansion Type":"Depth, Width","Package / Case":"32-LCC (J-Lead)","Product Status":"Obsolete","Bus Directional":"Uni-Directional","lifecycle_stage":"eol_hot","Voltage - Supply":"3 V ~ 3.6 V","Base Product Number":"7C4231","Operating Temperature":"0°C~70°C","Retransmit Capability":"No","Current - Supply (Max)":"20mA","Supplier Device Package":"32-PLCC (11.43x13.97)","Programmable Flags Support":"Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/06df22868d8a34fd15e9034e48ed2c13.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C4231V-15JXCT/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to CY7C4231V-15JXCT?","answer":"For a parametric match within the CY7C FIFO family, a cross-reference search at quote time is recommended."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C4231V-15JXCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C4231V-15JXCT when reusing this data.
