Product details
Overview
S25FL128LAGNFI010 from Infineon is a 128-Mbit serial NOR flash memory with quad SPI interface, 3.0–3.6 V supply voltage, 100 MHz clock frequency, and 133 MHz DDR read speed. It supports XIP (execute-in-place), sector erase, and deep power-down mode for low-power embedded boot code storage in industrial controllers.
For engineers reviewing the S25FL128LAGNFI010 datasheet, S25FL128LAGNFI010 pinout, S25FL128LAGNFI010 application, or S25FL128LAGNFI010 equivalent, key selection criteria include quad SPI timing compliance, 1.8 V I/O compatibility via VIO pin, sector protection granularity, and JEDEC JESD216 Rev C SFDP support for auto-configuration.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O (QPI) mode, supporting single/dual/quad I/O read and program operations. It uses a 64-byte page programming buffer and features a 4-KB uniform sector architecture with individual lock-bit protection.
The memory array is organized as 256 Kbytes × 64 bits, with hardware reset capability and status register polling for write/erase completion. It complies with JEDEC JESD216C for SFDP table parsing and supports volatile/non-volatile configuration register writes.

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 |
|---|---|---|---|
| Cypress S25FL128SAGNFI000 | Same die, identical pinout and timing, but lacks VIO pin - requires 3.3 V I/O only | Not suitable for mixed-voltage systems with 1.8 V MCU interfaces | Select when host operates exclusively at 3.3 V and cost optimization is prioritized |
| Winbond W25Q128JVSIM | 128 Mbit, 1.8 V core/I/O, no VIO pin, different SFDP layout and sector protection scheme | Requires firmware driver adaptation for protection and configuration register access | Choose for 1.8 V-only designs where Infineon's VIO flexibility is unnecessary |
Compared with S25FL128SAGNFI000 and W25Q128JVSIM, the S25FL128LAGNFI010 uniquely supports dual-voltage I/O via VIO, enabling drop-in use across 1.8 V and 3.3 V host platforms without level-shifter redesign.

FAQ
Is S25FL128LAGNFI010 compatible with standard SPI controllers?
Yes - it supports legacy SPI mode (single I/O) alongside dual and quad I/O modes. Standard SPI controllers can issue commands and read data using SO and SI pins only, though quad mode requires hardware and firmware support for full performance.
What is the purpose of the VIO pin?
The VIO pin supplies independent voltage (1.7–3.6 V) to the I/O buffers, enabling direct interface with 1.8 V or 3.3 V host processors without external level shifters. This simplifies PCB design and improves signal integrity in mixed-voltage systems.
Does this device support hardware write protection?
Yes - it features both software-controlled sector protection via status register bits and hardware write protection via the WP# pin. When WP# is held low, all write/erase operations to protected sectors are blocked regardless of software state.
Can S25FL128LAGNFI010 be used in automotive applications?
While not AEC-Q100 qualified in this specific part number, the S25FL128LAGNFI010 is built on Infineon's industrial-grade process and operates across -40°C to +105°C. Automotive qualification requires validation under AEC-Q100 stress tests and may be available in designated automotive-grade variants.
