Product details
Overview
S25FL256LDPBHV033 from Infineon is a 256-Mbit serial NOR flash memory with Quad SPI interface, 133 MHz clock frequency, and 3.0–3.6 V supply voltage, used for code storage and execution in industrial microcontroller boot systems.
For engineers reviewing the S25FL256LDPBHV033 datasheet, S25FL256LDPBHV033 pinout, S25FL256LDPBHV033 application, or S25FL256LDPBHV033 equivalent, key selection criteria include read latency, sector erase granularity, write endurance, and XIP (execute-in-place) capability in embedded firmware storage designs.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with Quad I/O (QPI) mode support, enabling up to 532 MB/s effective throughput. It uses uniform 4-KB sectors and 64-KB blocks for erase operations, with a dedicated 8-KB parameter sector for configuration data storage.
The memory supports both volatile and non-volatile status register writes, hardware reset via RESET# pin, and deep power-down mode consuming ≤10 µA. It complies with JEDEC JESD216B for SFDP (Serial Flash Discoverable Parameters) table reporting.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress S25FL256SAGNFI010 | Same density and QPI interface but uses 16-pin SOIC package; lacks secure OTP sector | Not suitable for ASIL-B or secure boot where key storage is required | Select when board layout allows larger footprint and security features are unnecessary |
| Winbond W25Q256JWEIQ | 256-Mbit Quad SPI flash with 4-byte addressing; no SFDP v1.6 support; 100K cycle endurance same | Limited auto-configuration capability; requires manual timing register setup | Prefer when legacy MCU drivers lack SFDP parsing and layout constraints favor smaller 8-pin WSON |
Compared with S25FL256LDPBHV033, the Cypress alternative trades security for package compatibility, while the Winbond part sacrifices standardized configuration for compact packaging-both require firmware-level adaptation to match Infineon's secure boot and auto-timing capabilities.

FAQ
Does S25FL256LDPBHV033 support execute-in-place (XIP) operation?
Yes, S25FL256LDPBHV033 supports true XIP operation across all supported interfaces (standard SPI, dual I/O, and quad I/O). This allows microcontrollers to execute code directly from flash memory without copying to RAM, reducing boot time and system memory requirements. The device guarantees zero-wait-state execution at up to 133 MHz clock frequency in QPI mode.
What is the purpose of the secure silicon sector in this device?
The secure silicon sector is an 8-KB one-time-programmable (OTP) area physically isolated from main memory. It stores cryptographic keys, device identifiers, and secure boot certificates. Once programmed, contents cannot be read back or modified, meeting requirements for root-of-trust implementation in ISO 26262 and IEC 62443-compliant systems.
How does SFDP support benefit system design?
SFDP (Serial Flash Discoverable Parameters) per JESD216B enables the host MCU to automatically read timing parameters, erase block sizes, and feature flags from an on-chip register table. This eliminates hardcoded timing values in firmware, improves portability across flash vendors, and simplifies qualification when migrating between compatible densities or revisions.
Is S25FL256LDPBHV033 qualified for automotive applications?
S25FL256LDPBHV033 is not AEC-Q100 qualified. It is rated for industrial temperature range (−40°C to +105°C) and intended for industrial, medical, and infrastructure applications. For automotive use, Infineon offers the pin-compatible AEC-Q100 Grade 2 variant S25FL256LDPBHV020, which shares identical electrical specs and feature set.
