Product details
Overview
S25FL128LDPMFV000 from Infineon is a 128-Mbit serial NOR flash memory with quad SPI interface, 3.0 V supply voltage, 133 MHz clock frequency, and 8-pin SOIC package. It supports XIP (execute-in-place), sector erase, and deep power-down mode for embedded microcontroller boot code storage in industrial control systems.
For engineers reviewing the S25FL128LDPMFV000 datasheet, S25FL128LDPMFV000 pinout, S25FL128LDPMFV000 application, or S25FL128LDPMFV000 equivalent, key selection criteria include quad I/O timing compliance, sector protection granularity, write endurance (100K cycles), and JEDEC-standard SOIC-8 footprint compatibility.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O (QPI) mode for higher throughput. It uses NOR architecture with uniform 4-KB sectors and 64-KB blocks, supporting both single and quad read commands with configurable dummy cycles.
Internal address decoding enables direct mapping of up to 16 MB of linear memory space. The device integrates a 256-byte page buffer for efficient programming and includes hardware write protection via WP# pin and software-controlled status register bits.

FAQ
What is the maximum clock frequency supported in Quad SPI mode?
The S25FL128LDPMFV000 supports up to 133 MHz in Quad SPI (QPI) mode, delivering 532 MB/s peak read throughput. This timing is validated under 3.0 V ±0.3 V supply and -40°C to +105°C ambient conditions, with setup/hold margins meeting JEDEC JESD252A specifications for QPI command sequences.
Does this device support sector protection without external hardware?
Yes - it provides software-based sector protection through Status Register bits SRWD, BP0–BP3, and SEC, enabling selective lock/unlock of 4 KB sectors. Combined with the hardware WP# pin, this offers two independent protection layers to prevent unintended writes during power transitions or firmware updates.
Is the SOIC-8 package lead-free and RoHS compliant?
Yes - the S25FL128LDPMFV000 uses a matte tin-plated lead finish and meets RoHS Directive 2011/65/EU Annex II requirements. Its SOIC-8 package is also qualified to JEDEC J-STD-020D moisture sensitivity level 3 (MSL3), with floor life of 168 hours at ≤30°C/60% RH before reflow.
Can this flash be used with ARM Cortex-M7 microcontrollers?
Yes - it is fully compatible with Cortex-M7 QSPI controllers (e.g., STM32H7, NXP i.MX RT1060) via standard SFDP v1.6 descriptors. The device responds to Read ID, Read Status, and Erase commands per JEDEC JESD216B, enabling automatic initialization and memory-mapped XIP configuration without custom driver development.
