Product details
Overview
S25FL256LDPBHI030 from Infineon is a 256-Mbit serial NOR flash memory with Quad SPI interface, 133 MHz clock frequency, 3.0 V supply voltage, and 100,000 program/erase cycles endurance, used in boot code storage for industrial microcontrollers.
For engineers reviewing the S25FL256LDPBHI030 datasheet, S25FL256LDPBHI030 pinout, S25FL256LDPBHI030 application, or S25FL256LDPBHI030 equivalent, key selection criteria include read latency, sector protection granularity, reset recovery time, and WSON-8 package compatibility with PCB layout constraints.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with Quad I/O (QPI) mode support, enabling 4-bit data transfers per clock cycle. It uses uniform 256 KB sectors and supports both volatile and non-volatile configuration registers for status and control.
It features hardware write protection via WP# pin and software-controlled block protection using the Status Register Block Protect bits. Reset recovery time is guaranteed at ≤ 30 µs after power-up or hardware reset.

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 |
|---|---|---|---|
| Cypress S25FL256SAGNFI010 | Same density and QPI interface, but 16-pin SOIC package instead of WSON-8 | Requires larger PCB footprint and lacks thermal performance of WSON-8 in high-density layouts | Select when board space allows SOIC and thermal derating is not required |
| Winbond W25Q256JWEIQ | 256 Mbit, 133 MHz, but uses DTR (Double Transfer Rate) mode instead of QPI; different command set | Requires host driver rework for DTR protocol and lacks hardware WP# pin | Select only if host controller supports DTR and software-based protection suffices |
Compared with S25FL256SAGNFI010 and W25Q256JWEIQ, the S25FL256LDPBHI030 offers superior thermal performance in compact WSON-8 packaging and native hardware write protection-critical for industrial and automotive designs where layout density and fail-safe operation are prioritized.

FAQ
Is S25FL256LDPBHI030 qualified for automotive applications?
No. This part is specified for industrial temperature range (−40°C to +105°C) and carries industrial qualification only. It does not meet AEC-Q100 requirements. For automotive use, Infineon offers the S25FL256L0LQBI010 variant, which is AEC-Q100 Grade 2 qualified and shares identical electrical specs except for extended temperature validation and additional automotive test screening.
What is the minimum VCC voltage for reliable operation?
The absolute minimum VCC is 2.7 V per the datasheet. Operation below this voltage risks incomplete program/erase verification, increased bit errors, and failure to enter or exit deep power-down mode correctly. Systems must maintain VCC ≥ 2.7 V throughout all active and standby states, including transient load conditions.
Does it support XIP (eXecute-In-Place) mode?
Yes. The device supports XIP in both standard SPI and QPI modes. Host processors with appropriate memory-mapped SPI controllers can execute code directly from the flash without copying to RAM, provided latency settings (e.g., dummy cycles) are configured per the device's Read ID and configuration register values.
How is sector protection configured?
Sector protection is controlled via the Status Register Block Protect (BP2–BP0) bits and the hardware WP# pin. When WP# is asserted low, all sectors become read-only regardless of BP bit settings. Software protection is enabled only when WP# is high and BP bits are set to lock specific 256 KB sectors or groups, with no partial-sector locking capability.
