Product details
Overview
S25FL128LDPBHA033 from Infineon is a 128-Mbit serial NOR flash memory with 3.0 V supply voltage, 133 MHz Quad SPI interface, uniform 256-byte programming and 4-KB/32-KB/64-KB erase granularity, supporting XIP operation in automotive-grade temperature range (–40°C to +125°C). It serves as nonvolatile code storage in ADAS domain controllers.
For engineers reviewing the S25FL128LDPBHA033 datasheet, S25FL128LDPBHA033 pinout, S25FL128LDPBHA033 application, or S25FL128LDPBHA033 equivalent, key selection criteria include automotive AEC-Q100 qualification, Quad SPI read throughput, sector protection granularity, and embedded ECC for bit error correction.
Technical Context
This device implements a SPI-compatible command set with dual/quad I/O modes, supports volatile and nonvolatile configuration registers, and integrates on-die ECC capable of correcting single-bit errors per 512-byte sector. It uses stacked-die packaging for density scaling while maintaining standard SOIC-16 footprint.
The memory array is organized as 256 Kbytes × 64 bits, with write-protect features including hardware WP# pin control and software block protection. Erase suspend/resume functionality enables concurrent background operations during firmware updates.

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 S25FL128SAGMFI000 | Same die, different marking; identical electrical specs and package | No functional difference; used interchangeably in Infineon/Cypress co-branded designs | Select when sourcing from legacy Cypress-designated BOMs or distributor stock with older part branding |
| Winbond W25Q128JVSIM | Lacks AEC-Q100 qualification; no on-die ECC; 104 MHz max Quad SPI speed | Restricted to industrial or consumer applications without automotive safety requirements | Use only in non-automotive systems where cost is prioritized over functional safety compliance |
Compared with S25FL128SAGMFI000, this part offers identical performance but reflects Infineon's post-acquisition branding; versus W25Q128JVSIM, it adds AEC-Q100 qualification, on-die ECC, and higher-speed interface-critical for ASIL-B system firmware integrity.

FAQ
Is S25FL128LDPBHA033 pin-compatible with earlier S25FL128Lxxx variants?
Yes, it maintains identical SOIC-16 pinout and electrical interface compatibility with all S25FL128L-series devices, including S25FL128LAGMFI000 and S25FL128L0XMFI000. No PCB redesign is required for migration, though configuration register defaults may differ and require firmware verification.
Does this device support execute-in-place (XIP) mode?
Yes, S25FL128LDPBHA033 supports true XIP operation with zero wait-state access at 133 MHz Quad SPI, enabling direct code execution from flash without RAM loading. This reduces system memory footprint and improves boot determinism in safety-critical automotive applications.
What is the endurance and data retention specification?
The device guarantees 100,000 program/erase cycles per sector and 20-year data retention at 125°C junction temperature. These values are validated per AEC-Q100 stress test conditions and apply across the full automotive temperature range without derating.
How is the secure silicon sector accessed and programmed?
The 256-byte secure silicon sector is accessed via dedicated SPI commands (0x42/0x44) and can be permanently locked after programming using the OTP lock bit. Once locked, contents cannot be read or modified, providing tamper-resistant storage for cryptographic keys and secure boot manifests.
