Cypress lists the CY7C1019B-12VC as obsolete. ## Package and footprint: 32-SOJ The part comes in a 32-SOJ (Small Outline J-lead) package with a 0.400-inch body width and 10.16 mm width. It is surface-mount, but the J-lead form factor is less common today than SOIC or TSSOP — make sure your pick-and-place machine has the correct nozzle and feeder for J-lead parts. The supplier device package is 32-SOJ, and the shipping medium is Tube, not Tape & Reel, which may affect your assembly line's feeder setup.","metaTitle":"CY7C1019B-12VC Cypress 1Mbit Async SRAM, 12 ns, 32-SOJ","metaDescription":"Cypress CY7C1019B-12VC is a 1Mbit (128K x 8) asynchronous SRAM with 12 ns access time, 4.5V–5.5V supply, in a 32-SOJ package.","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 - Asynchronous","Access Time":"12 ns","Memory Size":"1Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"32-BSOJ (0.400\\\", 10.16mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"CY7C1019","Memory Organization":"128K x 8","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"32-SOJ","Write Cycle Time - Word, Page":"12ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/039d9aa9a438ccba40a53cac7ea08571.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1019B-12VC/alternatives.json"},"ai":{"faq":[{"question":"What is a direct replacement for the CY7C1019B-12VC?","answer":"There is no official Cypress replacement listed for this exact order code. Any pin-compatible alternative must be a 128K x 8 asynchronous SRAM in a 32-SOJ package with a 12 ns or faster access time and a 5 V supply. Several vendors (ISSI, Alliance Memory, Renesas) offer current-production parts in the same footprint, but you must verify the pinout — particularly the chip-enable and output-enable pin assignments — against the original Cypress datasheet before committing the BOM."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1019B-12VC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1019B-12VC when reusing this data.
