Product details
Overview
S25FL256LAGBHM023 from Infineon is a 256-Mbit serial NOR flash memory with quad SPI interface, 3.0–3.6 V supply voltage, 133 MHz clock frequency, and 8-pin SOIC package. 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 S25FL256LAGBHM023 datasheet, S25FL256LAGBHM023 pinout, S25FL256LAGBHM023 application, or S25FL256LAGBHM023 equivalent, key selection criteria include quad SPI timing compliance, 2.7 V minimum VCC tolerance, 100K program/erase cycles endurance, and JEDEC-standard SOIC-8 footprint compatibility.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O (QPI) mode for 4-bit data transfers per clock cycle. It uses a uniform 256 KB sector architecture with configurable 4-KB subsectors and supports both volatile and non-volatile status register writes.
Internal write state machine handles all program and erase operations autonomously; no external command sequencing is required beyond issuing the initial instruction. The device includes hardware reset support and a dedicated write-protect pin (WP#) for sector-level lock control.

| 3 (HOLD#) | Hold Control | Pauses ongoing SPI transfer without chip deselect; used in multi-master systems |
| 4 (GND) | Ground | Reference return path for VCC and VIO; must be low-inductance connection |
| 5 (SI / IO0) | Serial Input / Quad I/O 0 | Primary data input in single/dual mode; bidirectional in quad mode |
| 6 (SO / IO1) | Serial Output / Quad I/O 1 | Primary data output in single/dual mode; bidirectional in quad mode |
| 7 (SCLK) | Serial Clock | Master-generated clock; max 133 MHz for QPI read; duty cycle 40–60% |
| 8 (VCC) | Core Supply | 3.0–3.6 V core voltage; requires 0.1 µF ceramic bypass near pin |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL256SAGMFI000 | Same density and SOIC-8 package but with 1.7–2.0 V VIO range; lacks deep power-down mode | Targeted at ultra-low-voltage microcontrollers; unsuitable for 3.3 V-only designs | Select only when interfacing with 1.8 V I/O domains and power budget excludes deep sleep |
| MX25L25645GMI-13G | 256 Mbit, SOIC-8, but rated for 105°C operation and includes dual/quad enable bit in status register | Preferred for extended temperature deployments; requires different status register initialization | Choose for outdoor or under-hood applications where ambient exceeds 85°C |
Compared with S25FL256SAGMFI000, this part offers deeper power savings and broader VIO flexibility; versus MX25L25645GMI-13G, it trades extended temperature rating for tighter timing control and simpler register configuration in standard industrial environments.

FAQ
What is the maximum clock frequency supported in Quad SPI mode?
The S25FL256LAGBHM023 supports up to 133 MHz in Quad SPI (QPI) mode, delivering 532 MB/s effective read throughput. This frequency is specified under 3.0–3.6 V VCC and 1.65–3.6 V VIO conditions with proper signal integrity layout. Exceeding 133 MHz may cause read errors or timing violations.
Does this device support execute-in-place (XIP) operation?
Yes, the device supports true XIP operation via its linear address space and fast random-access read performance. When connected to a processor with quad SPI memory-mapped interface, instructions can be fetched directly from flash without copying to RAM, reducing boot time and SRAM usage in resource-constrained systems.
Is the S25FL256LAGBHM023 qualified for automotive applications?
No, this specific variant is not AEC-Q100 qualified. It is rated for industrial temperature range (–40°C to +85°C). For automotive use, Infineon offers the S25FL256L0XMFI000 variant, which carries AEC-Q100 Grade 2 certification and extended temperature testing.
How is sector protection configured on this device?
Sector protection is controlled through the Status Register (SR) and the hardware WP# pin. The SR allows software-based locking of individual 256 KB sectors or the entire array, while WP# provides hardware-level protection for top/bottom sectors. Both mechanisms can be used simultaneously for layered security.
