For a production BOM, qualifying a pin-compatible second source is advisable. ## 15 ns — what it buys on the bus The 15 ns access time matches the write cycle time. This is a legacy fine-pitch surface-mount footprint, common in the late-1990s through mid-2000s.","metaTitle":"Cypress CY7C199-15ZC 256Kbit Asynchronous SRAM, 15 ns","metaDescription":"Cypress CY7C199-15ZC 256Kbit (32K x 8) asynchronous SRAM, 15 ns access time, 4.5V-5.5V supply, 0°C-70°C, 28-TSOP I.","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":"Bag","Technology":"SRAM - Asynchronous","Access Time":"15 ns","Memory Size":"256Kbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"28-TSSOP (0.465\\\", 11.80mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"CY7C199","Memory Organization":"32K x 8","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"28-TSOP I","Write Cycle Time - Word, Page":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fdb7371c062b50d7b235e5d86581da64.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C199-15ZC/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C199-15ZC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C199-15ZC when reusing this data.
