Product details
Overview
S25FL128LAGBHB023 from Infineon is a 128-Mbit serial NOR flash memory with Quad SPI interface, 3V supply voltage, 133 MHz clock frequency, and 8-pin SOIC package. It supports XIP (execute-in-place), dual/quad I/O modes, and sector-erase architecture for embedded boot code storage in microcontroller-based systems.
For engineers reviewing the S25FL128LAGBHB023 datasheet, S25FL128LAGBHB023 pinout, S25FL128LAGBHB023 application, or S25FL128LAGBHB023 equivalent, key selection criteria include erase/program cycle endurance, data retention at elevated temperature, write protection granularity, and SPI command compatibility with host MCU firmware.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O (QPI) mode for high-speed data transfer. It uses a 64-byte page programming buffer and supports uniform 4-KB sector erase, 32-KB block erase, and 64-KB block erase commands.
Internal write state machine handles all program and erase operations autonomously. The device includes hardware write protection via WP# pin and software-controlled status register bits (SRWD, BP0–BP3) for flexible sector locking.
Key Specifications

| Interface | Quad SPI (QPI) - enables up to 532 MB/s effective throughput with 133 MHz clock and 4-bit data bus |
| Supply Voltage | 2.7 V to 3.6 V - compatible with 3.3 V logic domains and tolerant of rail variation in industrial power supplies |
| Erase Endurance | 100,000 cycles per sector - supports field firmware updates over product lifetime |

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 |
|---|---|---|---|
| MX25L12833FZNI-10G | 1.8 V core supply; different command set (no QPI); 104 MHz max clock | Requires level-shifting in 3.3 V systems; lacks XIP-optimized timing for fast boot | Select only if system uses 1.8 V I/O and legacy SPI-only host controller |
| W25Q128JVSIM | Standard SPI only; no QPI mode; 10-year data retention at 85°C | Limited throughput for large firmware loads; lower endurance (10K cycles) | Prefer for cost-sensitive designs where quad bandwidth and long-term field updates are not required |
Compared with MX25L12833FZNI-10G and W25Q128JVSIM, S25FL128LAGBHB023 delivers higher throughput via QPI, superior endurance for frequent field updates, and extended data retention-making it optimal for automotive and industrial applications demanding long lifecycle reliability.

FAQ
What is the maximum clock frequency supported in Quad SPI mode?
The S25FL128LAGBHB023 supports up to 133 MHz in Quad SPI (QPI) mode, delivering 532 MB/s effective throughput. This frequency is specified under standard load conditions (CL = 10 pF) and requires proper PCB layout with controlled impedance traces and matched trace lengths for all four I/O lines to maintain signal integrity.
Does this device support execute-in-place (XIP) operation?
Yes, the S25FL128LAGBHB023 supports XIP mode, allowing microcontrollers to fetch and execute instructions directly from flash without loading into RAM. This reduces system memory requirements and accelerates boot time, especially when paired with MCUs featuring configurable prefetch buffers and cache line alignment support.
How is write protection implemented on this flash memory?
Write protection is implemented through both hardware and software mechanisms: the WP# pin provides active-low physical lock for top/bottom sectors, while status register bits (SRWD, BP0–BP3) enable software-selectable sector locking. Both methods can be used concurrently, with WP# taking precedence when asserted.
What erase granularities are available?
The device supports three erase granularities: uniform 4-KB sectors, 32-KB blocks, and 64-KB blocks. Sector erase enables fine-grained firmware patching; block erase optimizes speed for larger image updates. All erase operations are internally managed by the on-chip state machine and require no external timing control.
