Product details
Overview
S25FL128LAGNFB010 from Infineon is a 128-Mbit serial NOR flash memory with quad SPI interface, 3.0 V supply voltage, 100 MHz clock frequency, and uniform 4-KB sector architecture. It serves as non-volatile program/data storage in microcontroller boot code and firmware update applications.
For engineers reviewing the S25FL128LAGNFB010 datasheet, S25FL128LAGNFB010 pinout, S25FL128LAGNFB010 application, or S25FL128LAGNFB010 equivalent, key selection criteria include sector erase granularity, quad I/O throughput, write protection scheme, and industrial temperature range support.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O mode for high-speed data transfer. It supports both single and quad I/O read commands, with configurable dummy cycles and latency tuning for timing alignment across system clocks.
The memory array is organized into 64 uniform 4-KB sectors and 2048 256-byte pages, enabling flexible erase/write operations. Write protection is implemented via hardware (WP# pin) and software (status register bits), supporting top/bottom sector locking and volatile/non-volatile configuration.
Key Specifications

FAQ
What is the maximum supported clock frequency for quad I/O read operations?
The S25FL128LAGNFB010 supports up to 100 MHz for quad I/O read commands, delivering up to 400 MB/s theoretical bandwidth. This frequency is validated across the full industrial temperature range and requires proper PCB layout with matched trace lengths and controlled impedance.
Does this device support execute-in-place (XIP) operation?
Yes, the device supports XIP mode via continuous read commands with wrap-around addressing. It provides deterministic latency and no internal prefetch buffer, allowing direct CPU instruction fetch from flash without external RAM buffering in resource-constrained MCUs.
How is write protection implemented on this part?
Write protection uses both hardware and software methods: the WP# pin locks sectors when pulled low, while status register bits (SRWD, BP0–BP3) configure top/bottom sector protection. Protection is non-volatile unless cleared by a specific unlock sequence, ensuring robustness against power loss during updates.
Is an external high-voltage supply required for programming or erasing?
No external high-voltage supply is needed. The device integrates an internal charge pump that generates the ~9 V required for program and erase operations from the standard 3.3 V VCC rail, simplifying board-level power design and eliminating dedicated HV regulators.
