Product details
Overview
S25FL128LDPBHI020 from Infineon is a 128-Mbit serial NOR flash memory with quad SPI interface, 1.8 V supply voltage, and 133 MHz read clock frequency. It supports XIP (execute-in-place), dual/quad I/O protocols, and offers 100K program/erase cycles with 20-year data retention. Used in industrial PLC firmware storage and automotive ADAS boot code storage.
For engineers reviewing the S25FL128LDPBHI020 datasheet, S25FL128LDPBHI020 pinout, S25FL128LDPBHI020 application, or S25FL128LDPBHI020 equivalent, key selection criteria include quad SPI timing compliance, 1.8 V VCC tolerance, sector protection granularity, and AEC-Q100 Grade 2 qualification for automotive use.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O commands compliant with JEDEC JESD216B. It integrates a 256-byte page write buffer and supports uniform 4-KB sectors and 64-KB blocks for flexible erase management.
The memory array is organized as 64 K × 16 bits, enabling byte-addressable reads and page-aligned programming. Built-in hardware reset and deep power-down modes support low-power embedded operation with typical 25 µA standby current.

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 |
|---|---|---|---|
| S25FL128SAGMFI000 | Same density and voltage, but 3.0 V supply and no AEC-Q100 qualification | Targeted at industrial/commercial systems without automotive thermal or reliability requirements | Select when operating voltage is 2.7–3.6 V and automotive qualification is unnecessary |
| MX25L12833FZNI-10G | 1.8 V supply and 104 MHz max clock; lacks AEC-Q100 Grade 2 and program/erase suspend | Used in cost-sensitive consumer electronics where safety certification is not required | Choose only if deep power-down current <5 µA and suspend functionality are noncritical |
Compared with S25FL128SAGMFI000 and MX25L12833FZNI-10G, the S25FL128LDPBHI020 uniquely combines AEC-Q100 Grade 2 qualification, 133 MHz quad SPI performance, and program/erase suspend-enabling safe, high-speed firmware updates in automotive and industrial safety-critical systems.

FAQ
Is S25FL128LDPBHI020 pin-compatible with earlier S25FL128P variants?
No. S25FL128LDPBHI020 uses an 8-pin SOIC package with different pin assignments than the 16-pin SOIC used in S25FL128P. The L-series replaces parallel address/data buses with quad SPI I/O, eliminating dedicated address pins and consolidating functions onto SI/SO/WP#/HOLD#.
Does this device support octal SPI or DDR interface modes?
No. S25FL128LDPBHI020 supports only single, dual, and quad SPI modes per JEDEC JESD216B. It does not implement octal DTR, DDR clocking, or any non-JEDEC-standard high-speed interface extensions.
What is the minimum VCC voltage for reliable program/erase operations?
The minimum valid VCC for program and erase is 1.7 V, as specified in the datasheet Absolute Maximum Ratings and DC Characteristics tables. Operation below 1.7 V may result in incomplete programming or partial sector erasure.
Can hardware write protection be disabled after initial configuration?
Yes. Hardware write protection via WP# pin is active only when WP# is driven low; it is inactive when WP# is pulled high. Status register block protection bits can be cleared via Write Enable and Write Status Register commands, allowing dynamic reconfiguration.
