For production builds, this means new- and surplus-stock procurement through independent distribution is the only channel. If the BOM still calls for this exact footprint and timing, secure inventory now — the surplus pool shrinks as existing stocks are consumed. In a 5 V system with a 50 MHz bus (20 ns period), this leaves zero margin for address decoding, trace delay, and setup time at the processor — so this part is really suited to 25–33 MHz buses where you have 10–15 ns of slack.","metaTitle":"CY7C199C-20VXC Infineon 256Kbit Async SRAM, 20 ns, SOJ-28","metaDescription":"Infineon CY7C199C-20VXC 256Kbit asynchronous SRAM, 20 ns access time, 32K x 8 organization, 4.5V-5.5V supply, 28-SOJ.","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":"20 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":"0°C ~ 70°C (TA)","Supplier Device Package":"28-SOJ","Write Cycle Time - Word, Page":"20ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/aea969ef93c389c22f1244d5fae0f19f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the access time of CY7C199C-20VXC?","answer":"The access time is 20 ns, which also matches the write cycle time of 20 ns.
