Infineon lists the CY7C199CNL-15VXIT as Obsolete. No last-time-buy window remains open from the factory. No official replacement part number has been published by Infineon for this specific variant. At 15 ns address-access time, the part can keep up with a 33 MHz bus with zero wait states if the address setup and hold margins are within a few nanoseconds. For a 40 MHz or faster bus, you will likely need one wait state or a faster SRAM. This speed grade is the -15 variant; slower -20 or -25 parts exist in the same family but would stretch the bus cycle and may fail timing on a design originally laid out for 15 ns. ## Tape & Reel delivery for automated assembly No tube or tray variants for this suffix — if your rework bench needs a single loose part, the reel must be cut or a tray-shipped sibling sourced separately.","metaTitle":"Infineon CY7C199CNL-15VXIT 256Kbit Async SRAM, 15 ns, 5 V","metaDescription":"Infineon CY7C199CNL-15VXIT 256Kbit asynchronous SRAM with 15 ns access time, 4.5V-5.5V supply, -40°C to 85°C.","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":"Tape & Reel (TR)","Technology":"SRAM - Asynchronous","Access Time":"15 ns","Memory Size":"256Kbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"28-BSOJ (0.300\\\", 7.62mm 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":"-40°C ~ 85°C (TA)","Supplier Device Package":"28-SOJ","Write Cycle Time - Word, Page":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6398b56c6f552b3095850c2846381043.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy CY7C199CNL-15VXIT and how do I get a price?","answer":"Submit an RFQ through this listing; we confirm availability and current pricing at quote time.
