Overview
S25FL128LDPMFI001 from Infineon is a 128-Mbit serial NOR flash memory with quad SPI interface, 3V supply voltage, and 100 MHz clock frequency, supporting XIP (execute-in-place) operation in embedded microcontroller boot applications.
For engineers reviewing the S25FL128LDPMFI001 datasheet, S25FL128LDPMFI001 pinout, S25FL128LDPMFI001 application, or S25FL128LDPMFI001 equivalent, key selection criteria include read latency, sector erase granularity, write endurance, and industrial temperature range compliance.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O (QPI) mode for high-speed data transfer. It supports dual and quad read commands, with configurable dummy cycles and address width (24- or 32-bit).
Internal architecture includes a 64-KB uniform sector layout, configurable block protection via status register bits, and hardware reset capability. The memory array is organized as 16,384 pages of 256 bytes each.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL128SAGMFI001 | Same density and package, but uses 1.8 V core supply with 3.0 V I/O; different VCC pin assignment | Requires level-shifting in 3.3 V systems; not drop-in compatible without schematic revision | Select only when migrating to lower-power 1.8 V core architecture with compatible I/O voltage translation |
| MX25L12833FZNI-10G | 128 Mbit, 3 V, SOIC-8, but lacks QPI mode and has slower 80 MHz max clock | Supports only standard/dual SPI; insufficient bandwidth for XIP-heavy applications | Choose for cost-sensitive designs where quad-speed throughput is non-critical and legacy SPI drivers are used |
Compared with S25FL128SAGMFI001 and MX25L12833FZNI-10G, the S25FL128LDPMFI001 uniquely delivers quad SPI performance at 100 MHz with industrial temperature rating in a standard 3 V SOIC-8, making it optimal for boot-critical, thermally demanding embedded systems.

FAQ
What is the maximum clock frequency supported in Quad SPI mode?
The S25FL128LDPMFI001 supports up to 100 MHz in Quad SPI (QPI) mode, delivering 400 MB/s effective throughput. This frequency is validated across the full industrial temperature range (-40°C to +105°C) and requires proper signal integrity design including controlled impedance traces and termination.
Does this device support execute-in-place (XIP) operation?
Yes, the S25FL128LDPMFI001 supports XIP operation via its Quad SPI interface, allowing microcontrollers to directly fetch and execute code without loading into RAM. This requires MCU SPI controller support for QPI mode and proper cache coherency handling for instruction fetches.
How is sector protection implemented on this flash device?
Sector protection is implemented through both software-configurable status register bits (SRWD, BP0–BP3) and hardware WP# pin assertion. When WP# is low, all sectors become write-protected; software protection allows selective locking of individual 64 KB sectors independent of WP# state.
Is a dedicated reset pin available on this package?
Yes, the S25FL128LDPMFI001 includes a dedicated RESET# pin (Pin 7 in SOIC-8). Asserting this pin low resets internal state machines and returns the device to standby mode, enabling reliable recovery after brown-out or communication errors without power cycling.
