Product details
Overview
S25FL128LDPBHI033 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 - deployed in industrial PLC firmware storage and automotive infotainment boot code storage.
For engineers reviewing the S25FL128LDPBHI033 datasheet, S25FL128LDPBHI033 pinout, S25FL128LDPBHI033 application, or S25FL128LDPBHI033 equivalent, key selection criteria include Quad SPI timing compliance, 1.8 V VCC tolerance, sector protection granularity, and JEDEC JESD216 Rev C SFDP support for automatic configuration.
Technical Context
This device implements a 4-byte address mode with configurable dummy cycle count for high-speed read operations and supports both volatile and non-volatile status register writes. It integrates a 256-byte page programming buffer and hardware block protection via WP# pin and status register bits.
The memory array is organized as 64 Kbytes of uniform 4-Kbyte sectors, with erase suspend/resume capability and a dedicated 512-byte secure OTP area for unique device identifiers or cryptographic keys.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L12833FZCII00 | 3.3 V supply only; no 1.8 V operation; lacks SFDP Rev C support | Requires level-shifting in 1.8 V systems; no auto-configuration capability | Select only if legacy 3.3 V design exists and SFDP-driven initialization is not needed |
| W25Q128JVSIM | 1.8 V compatible but rated only to 105°C; no secure OTP area | Not qualified for extended-temperature automotive use; no hardware key storage | Choose for cost-sensitive consumer applications where OTP security is unnecessary |
Compared with MX25L12833FZCII00 and W25Q128JVSIM, S25FL128LDPBHI033 uniquely combines 1.8 V operation, JESD216 Rev C SFDP, and 512-byte secure OTP - making it the only option qualified for AEC-Q100 Grade 2 automotive boot storage with zero-touch configuration.

FAQ
Is S25FL128LDPBHI033 pin-compatible with earlier S25FL128S variants?
No. S25FL128LDPBHI033 uses an 8-pin SOIC package identical to S25FL128S, but its internal command set and status register layout differ - particularly in SFDP table structure and OTP access protocol. Hardware redesign is required for migration.
Does this device support octal SPI or DDR x4 modes?
No. S25FL128LDPBHI033 supports only single, dual, and quad SPI modes - including DDR quad read - but does not implement octal SPI or x8 I/O interfaces. Its maximum interface bandwidth is 532 MB/s in DDR quad mode at 133 MHz.
What is the purpose of the 512-byte secure OTP area?
The 512-byte secure OTP area is one-time programmable and permanently locked after writing. It stores cryptographic keys, device-specific identifiers, or calibration data that must remain tamper-proof and immune to firmware-level overwrite attempts.
Can HOLD# and WP# pins be used simultaneously in quad mode?
Yes. In quad SPI mode, HOLD# and WP# function as IO3 and IO2 respectively for data transfer, while retaining their hardware control roles when the device is not actively transferring data - enabling concurrent protection and suspension without external logic.
