Product details
Overview
S25FL256LAGNFM010 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), dual/quad I/O modes, and sector-erase architecture for embedded boot code storage in microcontroller-based systems.
For engineers reviewing the S25FL256LAGNFM010 datasheet, S25FL256LAGNFM010 pinout, S25FL256LAGNFM010 application, or S25FL256LAGNFM010 equivalent, key selection criteria include read latency, erase granularity, write protection scheme, and SPI command compatibility with host MCU firmware stacks.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O commands compliant with JEDEC JESD216B. It uses stacked-die technology to achieve 256 Mbit density in a single SOIC-8 package while maintaining pinout compatibility with lower-density family members.
Internal architecture includes a 256-byte page buffer, uniform 4-KB sectors, and a 64-KB block erase option. The device supports volatile and non-volatile status register configuration, including write enable latch and quad enable bit settings required for high-speed read operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Type | NOR flash - enables XIP execution directly from memory without loading to RAM |
| Capacity | 256 Mbit (32 MB) - sufficient for full firmware images plus configuration data in mid-tier MCUs |
| Interface | Quad SPI - delivers up to 532 MB/s effective throughput using 4-bit data lanes |
| Supply Voltage | 3.0–3.6 V - matches standard 3.3 V logic rails and avoids level-shifting circuitry |
| Max Clock Frequency | 133 MHz - supports fast read cycles with ≤8 ns address access time in quad mode |
| Erase Granularity | 4 KB sectors / 64 KB blocks - allows fine-grained firmware updates without full chip erase |
| Write Protection | Software-controlled via status register bits - prevents accidental overwrites during power transitions |
Pinout & Package
Package: 8-pin SOIC (Small Outline Integrated Circuit), 208-mil width, RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (SO) | Serial Output | Data output line for standard/dual/quad SPI reads; driven only during read commands |
| Pin 2 (SI) | Serial Input | Command/address/data input line for all write and erase operations |
| Pin 3 (WP#) | Write Protect | Active-low hardware write protection; overrides software lock when asserted |
| Pin 4 (GND) | Ground | Reference return path for all I/O and core logic; must be low-impedance |
| Pin 5 (HOLD#) | Hold Control | Pauses ongoing SPI transaction without deselecting device; used for bus arbitration |
| Pin 6 (SCLK) | Serial Clock | Master-generated clock synchronizing all data transfers; max 133 MHz |
| Pin 7 (CS#) | Chip Select | Active-low enable signal; device responds only when CS# is asserted |
| Pin 8 (VCC) | Power Supply | 3.0–3.6 V core and I/O supply; requires local 100 nF decoupling capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI Read Mode | Enables 4-bit parallel data transfer per clock cycle, doubling bandwidth vs. standard SPI |
| Uniform 4-KB Sector Architecture | Allows independent erasure of small firmware partitions without affecting adjacent code |
| Volatile Status Register Write | Permits runtime configuration changes (e.g., QE bit) without permanent NVSR programming |
| Hardware Write Protection (WP#) | Provides fail-safe protection against corruption during brown-out or reset conditions |
| JEDEC JESD216B Compliant SFDP | Enables automatic parameter discovery by host bootloader without hardcoded timing values |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress S25FL256SAGNFI000 | Same die, identical electrical specs, but shipped with factory-programmed security registers locked | Prevents post-manufacture reconfiguration of security features like OTP lock bits | Select when immutable security policy is required at system certification |
| Winbond W25Q256JWEIQ | 256 Mbit, 1.8 V core, different SFDP layout and command set; no hardware HOLD# pin | Requires MCU driver adaptation for 1.8 V I/O and lacks hold functionality for multi-master arbitration | Select only if system already uses 1.8 V SPI peripherals and does not require transaction pause capability |
Compared with S25FL256SAGNFI000, this part offers field-configurable security registers; compared with W25Q256JWEIQ, it ensures drop-in compatibility with existing 3.3 V industrial designs and retains HOLD# for robust bus sharing.

FAQ
What is the maximum supported clock frequency for Quad SPI read operations?
The S25FL256LAGNFM010 supports up to 133 MHz for Quad SPI read operations, delivering 532 MB/s effective throughput. This frequency is validated across the full industrial temperature range (-40°C to +85°C) 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 its Quad SPI interface, allowing the host MCU to fetch instructions directly from flash without copying to RAM. XIP requires proper cache coherency handling and alignment of executable code to 4-byte boundaries as specified in the device's command set documentation.
How is write protection implemented on this flash device?
Write protection is implemented through both hardware and software mechanisms: the WP# pin provides active-low physical lock, while status register bits (SRWD, BP0–BP3) enable sector- or block-level software locking. Both methods can be used concurrently for defense-in-depth firmware integrity.
Is the SOIC-8 package RoHS-compliant and lead-free?
Yes, the S25FL256LAGNFM010 uses a RoHS-compliant, lead-free 8-pin SOIC package with matte tin finish. It meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) and is qualified for reflow soldering per IPC/JEDEC J-STD-020 standards.
