Product details
Overview
S25FL256LAGMFI003 from Infineon is a 256-Mbit (32-MB) serial NOR flash memory with Quad SPI interface, 133 MHz clock frequency, and 1.8 V core supply voltage. It supports XIP (execute-in-place), dual/quad I/O modes, and sector erase granularity down to 4 KB. Used in industrial PLC firmware storage and embedded boot code retention.
For engineers reviewing the S25FL256LAGMFI003 datasheet, S25FL256LAGMFI003 pinout, S25FL256LAGMFI003 application, or S25FL256LAGMFI003 equivalent, key selection criteria include quad-SPI timing compliance, 4-KB sector erase capability, 1.8 V VCC tolerance, and industrial temperature range (-40°C to +85°C) support.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad-I/O command set compliant with JEDEC JESD216B. It uses stacked-die architecture for density scaling while maintaining single-die package footprint and pin compatibility with prior S25FL-L family members.
Internal architecture includes a 256-Mbit array organized as 512 uniform 64-KB sectors, with additional 4-KB parameter sectors for configuration and boot code. Erase suspend/resume and program suspend/resume functions are hardware-supported.
Key Specifications

| Interface | Quad SPI - enables 532 MB/s effective throughput using 133 MHz clock and 4-bit data bus |
| VCC Supply | 1.7–2.0 V - matches low-voltage SoC I/O domains and reduces power during read operations |
| Operating Temp | -40°C to +85°C - qualified for industrial control and outdoor edge gateway deployments |
| Erase Granularity | 4 KB sectors - allows fine-grained firmware updates without disturbing adjacent configuration data |
| Write Cycle Endurance | 100,000 cycles per sector - supports field-upgradable firmware with frequent patching |

Pinout & Package
Supplied in 16-pin SOIC (300 mil) package with standard SPI pinout and dedicated HOLD# and WP# control terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SO, SI, WP#, HOLD#, SCLK, CS# | Standard SPI signals | Direct connection to MCU SPI peripheral without level-shifting or glue logic |
| VCC, VSS | Power and ground | Single 1.8 V supply simplifies PMIC design and eliminates need for dual-rail regulators |
| NC | No connect | Unused pins left unconnected per Infineon design - no internal bonding or pull-up/down |
Key Features

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 |
|---|---|---|---|
| S25FL256SAGMFI000 | Same density and package, but 3.0 V VCC supply and 104 MHz max clock | Requires separate 3.0 V rail; not suitable for 1.8 V SoC designs | Select only when legacy 3.3 V system architecture mandates backward compatibility |
| MX25L25645GMI-13G | 256 Mbit, 1.8 V, but supports only dual I/O and lacks JESD216B SFDP table | Bootloader compatibility limited to basic SPI controllers without quad-mode auto-negotiation | Choose only if quad-SPI features are unused and cost sensitivity outweighs future upgrade flexibility |
Compared with S25FL256SAGMFI000 and MX25L25645GMI-13G, the S25FL256LAGMFI003 uniquely delivers quad-SPI performance at 1.8 V with full JESD216B compliance-enabling seamless integration into modern low-power, high-throughput boot architectures without voltage translation or firmware abstraction layers.

FAQ
Is S25FL256LAGMFI003 compatible with standard SPI controllers?
Yes-it operates in standard SPI mode (single I/O) at up to 80 MHz, fully supporting legacy controllers. Quad-SPI functionality requires explicit enablement via status register bit and is optional for basic read/write use cases.
Does this part support execute-in-place (XIP) operation?
Yes-hardware XIP is supported with deterministic read latency of ≤8 ns for sequential accesses. The device includes cache line wrap and prefetch buffer to sustain CPU instruction fetch without stalling.
What is the minimum erase block size?
The smallest erasable unit is a 4-KB sector. There are 128 such sectors in the top and bottom parameter blocks, enabling granular firmware patching without affecting main application code regions.
How is hardware write protection implemented?
Write protection is controlled by the WP# pin and two status register bits (SRWD and BP[3:0]). When WP# is asserted low, all non-volatile register writes and program/erase commands are blocked regardless of register settings.
