For BOM lines that still require this specific SRAM, independent distribution is the practical channel. We source per RFQ against your target quantity — no stock-holding claim, confirmed at quote time. ## 15 ns access time, 32K x 8 organization This is a 256Kbit asynchronous SRAM organized as 32K words by 8 bits. The 15 ns access time sets the read-cycle floor for the bus — the parallel interface latches data on the address-to-output delay, not a clock edge. The write cycle time matches the read at 15 ns, so back-to-back writes keep the bus at full throughput without wait states. ## 28-TSSOP footprint, commercial temp Housed in a 28-TSSOP package (0.465\", 11.80 mm width), with the supplier device package listed as 28-TSOP I. The 0.65 mm pitch is a standard footprint for 8-bit SRAMs — the same land pattern fits many 32K x 8 parts.","metaTitle":"CY7C199NL-15ZXCT SRAM 256Kbit 15ns 28-TSSOP Infineon","metaDescription":"CY7C199NL-15ZXCT is an obsolete 256Kbit asynchronous SRAM, 32K x 8, 15 ns access time, 4.5–5.5 V, commercial temp 0–70 °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-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":"$1.3900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1c127977d4e6c1639a31f948ff5c164c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for CY7C199NL-15ZXCT?","answer":"Infineon has not published an official successor for this exact order code. For a pin-compatible drop-in, look for other 32K x 8 asynchronous SRAMs in 28-TSSOP with 5 V supply and 15 ns access — e.g., the ISSI IS61C256AH-15TLI or Alliance AS7C256A-15TIN, though always confirm the footprint and timing match your layout."},{"question":"Is CY7C199NL-15ZXCT lead-free?","answer":"The suffix 'NL' in the order code typically indicates a lead-free (RoHS-compliant) finish for Cypress/Infineon SRAMs in this series.
