The 5 ns access time and 100 MHz clock rate support back-to-back reads and writes without dead cycles. ## Package and environment Housed in a 100-TQFP (14x14 mm), surface mount. The 0°C to 70°C commercial temperature range limits it to indoor, climate-controlled equipment — think network switches, base stations, or test gear in a lab. Not rated for the factory floor or under-hood use. The 100-pin footprint is common enough that layout guides are easy to find, but verify the pinout against your controller's memory controller; the ZBT interface is standardized but some vendors swap byte-lane enables. ## Sourcing and lifecycle Lifecycle status is Active. No end-of-life notice, no last-time-buy pressure. This part is current production and available through the independent distribution channel. For a BOM freeze or a new design, there's no LTB risk to manage. If you need a second-source option, the ZBT SRAM market has pin-compatible parts from other vendors at the same density and speed grade — check the package and timing specs against your controller's memory map before swapping.","metaTitle":"71V2556S100PFG SRAM 4.5Mbit, 5 ns Access, 100 MHz, 100-TQFP","metaDescription":"71V2556S100PFG synchronous ZBT SRAM, 4.5 Mbit (128K x 36), 5 ns access time, 100 MHz clock, 3.135-3.465 V supply, 100-TQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Package":"Bulk","Technology":"SRAM - Synchronous, SDR (ZBT)","Access Time":"5 ns","Memory Size":"4.5Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Clock Frequency":"100 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.135V ~ 3.465V","Memory Organization":"128K x 36","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"100-TQFP (14x14)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.11","stockQuantity":0,"priceTiers":[{"qty":74,"price":"$4.11000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/98b12ba9d777eec15fca0fb00a90f8fb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the access time of 71V2556S100PFG?","answer":"The access time is 5 ns, with a 100 MHz clock frequency.
