It comes in a 24-ball TBGA package (8x6 mm) for surface-mount assembly. This is a non-volatile memory intended for code shadowing, data logging, and configuration storage in embedded systems where a serial NOR flash provides a good balance of density, read speed, and pin count. ## 66 MHz clock and Quad SPI — what the interface means for throughput The 66 MHz clock frequency is the base rate for single-SPI reads. With Quad I/O, the effective throughput can reach 264 Mbps (66 MHz x 4 data lines), which is enough for fast firmware boot or streaming sensor data without needing a parallel bus. The QPI mode further reduces the command overhead by using the quad lines for address and command as well, which helps when the host controller supports it. For a design that needs to execute code in place (XIP) from flash, the 66 MHz speed keeps the CPU fed without wait states on many Cortex-M class MCUs running at similar clock rates. ## Industrial temperature range — where this part runs reliably This is not an extended-range part for under-hood or downhole use, but it handles the thermal cycling of a factory floor or a telecom cabinet without issue. The 24-BGA package has a small footprint (8x6 mm), which helps with board space, but the BGA requires careful PCB layout and X-ray inspection for solder joint quality in production.","metaTitle":"S25FL256LDPBHI020 NOR Flash, 256 Mbit, 66 MHz, Quad SPI","metaDescription":"S25FL256LDPBHI020 256 Mbit NOR Flash from Infineon's FL-L series, 66 MHz clock, Quad SPI/QPI interface, -40°C to 85°C, 24-BGA.","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":"256Mbit","Memory Type":"Non-Volatile","Memory Format":"FLASH","Mounting Type":"Surface Mount","Package / Case":"24-TBGA","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":"S25FL256","Memory Organization":"32M x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"24-BGA (8x6)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.8920","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Does S25FL256LDPBHI020 support 1.8V operation?","answer":"No. The supply voltage range is 2.7V to 3.6V.
