It uses a Quad I/O and QPI serial interface running at up to 66 MHz, which gives read throughput sufficient for direct code execution (XIP) from the Flash in most embedded MCU and FPGA configuration applications. ## Quad I/O and QPI — what they mean for read throughput Standard SPI reads one bit per clock cycle. Quad I/O and QPI use four data lines simultaneously, quadrupling the theoretical read throughput to 264 Mbps at 66 MHz. For designs that execute firmware directly from the Flash (eXecute In Place), this reduces boot time and improves code-fetch performance compared to a standard SPI NOR part. The QPI mode also reduces command overhead by sending opcodes over the same four-bit bus. ## Package and footprint — 16-SOIC wide body The S25FL128LDPMFI000 comes in a 16-SOIC package with a 7.50 mm body width (0.295\" pitch). This is a standard, widely used footprint for serial NOR Flash, compatible with most PCB assembly lines. The surface-mount package is suitable for reflow soldering; MSL level should be verified from the latest datasheet for moisture sensitivity handling.","metaTitle":"S25FL128LDPMFI000 NOR Flash, 128 Mbit, SPI Quad I/O, 66 MHz","metaDescription":"Infineon S25FL128LDPMFI000 128 Mbit SPI NOR Flash, 66 MHz clock, Quad I/O, -40 to 85°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"FL-L","Package":"Tray","Technology":"FLASH - NOR","Memory Size":"128Mbit","Memory Type":"Non-Volatile","Memory Format":"FLASH","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","Product Status":"Active","Clock Frequency":"66 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI - Quad I/O, QPI","Voltage - Supply":"2.7V ~ 3.6V","Base Product Number":"S25FL128","Memory Organization":"16M x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"16-SOIC","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3552","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://www.infineon.com/dgdl/Infineon-S25FL256L_S25FL128L_256-MB_(32-MB)_128-MB_(16-MB)_3.0_V_FL-L_FLASH_MEMORY-DataSheet-v09_00-EN.pdf?fileId=8ac78c8c7d0d8da4017d0ed40e335224","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to S25FL128LDPMFI000 in this component family?","answer":"The base product number S25FL128L covers the family.
