Product details
Overview
S25FL128LAGBHV033 from Infineon is a 128-Mbit serial NOR flash memory with 3.0 V supply voltage, 104 MHz Quad SPI interface, and uniform 256-byte programmable sectors. It supports XIP (execute-in-place) operation and is used in industrial PLC firmware storage and automotive infotainment boot code retention.
For engineers reviewing the S25FL128LAGBHV033 datasheet, S25FL128LAGBHV033 pinout, S25FL128LAGBHV033 application, or S25FL128LAGBHV033 equivalent, key selection criteria include sector architecture compatibility, Quad SPI timing compliance, erase suspend/resume capability, and AEC-Q100 Grade 2 qualification for automotive use cases.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with Quad I/O (QPI) mode enabled via configuration register bit CR[1]. It uses a 4-byte address mode for full 128 Mbit addressing and supports both volatile and non-volatile status register writes.
The memory array is organized as 65,536 sectors of 256 bytes each, with erase granularity configurable to 4-KB, 32-KB, or 64-KB blocks. Write protection is enforced via hardware WP# pin and software status register bits SRP0/SRP1.

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 133 MHz Quad SPI and no AEC-Q100 qualification | Targeted at industrial computing, not automotive-grade environments | Select when higher clock speed is needed and automotive qualification is unnecessary |
| MX25L12833FZNI-10G | 104 MHz Quad SPI, but only AEC-Q100 Grade 3 (–40 °C to +85 °C) and no deep power-down mode | Suitable for cabin electronics but not under-hood ECUs | Choose for cost-sensitive consumer infotainment where extended temperature range is not required |
Compared with S25FL128SAGMFI000 and MX25L12833FZNI-10G, the S25FL128LAGBHV033 uniquely combines AEC-Q100 Grade 2 qualification, deep power-down (10 µA), and uniform 256-byte sectors-making it the only option qualified for under-hood automotive boot memory with low-power idle states.

FAQ
What is the maximum operating temperature range for S25FL128LAGBHV033?
The S25FL128LAGBHV033 is qualified per AEC-Q100 Grade 2, supporting continuous operation from –40 °C to +105 °C ambient temperature. This rating applies to the full device-including core logic, I/O buffers, and memory array-and is validated across voltage, timing, and data retention specifications per JEDEC JESD47 stress testing protocols.
Does S25FL128LAGBHV033 support execute-in-place (XIP) mode?
Yes, the S25FL128LAGBHV033 supports XIP operation via its Quad SPI interface. When configured with appropriate memory-mapped controller settings, the host processor can fetch instructions directly from flash without copying to RAM, reducing boot latency and external memory footprint. XIP requires QPI mode and proper address mapping alignment per Infineon Application Note AN42902.
How many program/erase cycles does this part guarantee per sector?
Infineon guarantees 100,000 program/erase cycles per individual 256-byte sector. This endurance rating is specified under typical operating conditions (VCC = 3.0 V to 3.6 V, TA = 25 °C) and remains valid across the full qualified temperature range when derated per JEDEC JESD22-A117 lifetime projection methodology.
Is there hardware write protection independent of software configuration?
Yes, the WP# (Write Protect) pin provides hardware-level write protection. When driven low, it disables all program and erase commands regardless of status register settings. This feature operates independently of software configuration and remains active even during power transitions, ensuring robust protection against accidental firmware corruption during system reset or brown-out events.
