Product details
Overview
S25FL256LAGNFB010 from Infineon is a 256-Mbit serial NOR flash memory with Quad SPI interface, 133 MHz clock frequency, uniform 256-byte sector erase, and 3.0–3.6 V supply voltage. It supports XIP mode and is used in industrial PLC firmware storage and embedded boot code retention.
For engineers reviewing the S25FL256LAGNFB010 datasheet, S25FL256LAGNFB010 pinout, S25FL256LAGNFB010 application, or S25FL256LAGNFB010 equivalent, key selection criteria include erase granularity, write cycle endurance, data retention period, and Quad SPI command set compliance.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended Quad I/O (QPI) mode for high-speed read throughput. It uses a 4-byte address space to access the full 256 Mbit density and supports both volatile and non-volatile configuration register writes.
Erase operations are supported at sector (256 B), block (64 KB), and chip levels. The memory array is organized as 512 pages of 512 bytes each, with internal ECC for bit error correction during read operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 256 Mbit (32 MB) - supports full bootloader + OS image storage in compact footprint |
| Interface | Quad SPI (QPI) - enables 532 MB/s peak read bandwidth with single I/O clock |
| Max Clock Frequency | 133 MHz - meets real-time boot latency requirements for industrial controllers |
| Erase Granularity | Uniform 256-byte sectors - allows fine-grained firmware update without disturbing adjacent code |
| Endurance | 100,000 program/erase cycles - ensures >10-year field life under daily firmware patching |
| Data Retention | 20 years at 85°C - validated for extended operation in uncooled control cabinets |
Pinout & Package
Package: 16-pin SOIC (300 mil, GNFB suffix), RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SO, IO0–IO3 | Serial Data I/O | Quad bidirectional data lines supporting single/dual/quad I/O modes |
| SI, SO | Standard SPI I/O | Legacy dual-I/O compatibility for backward design reuse |
| SCLK | Serial Clock Input | Drives all timing-critical commands including fast-read and QPI entry |
| CS# | Chip Select | Active-low enable; must be asserted before any command sequence |
| WP# | Write Protect | Hardware lock for top/bottom 4 KB sectors during power-up or runtime |
| HOLD# | Hold Control | Pauses ongoing read transfer without losing internal address pointer |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI with wrap-around burst | Enables continuous 256-byte reads in <10 µs, reducing CPU wait states in boot sequence |
| Volatile/non-volatile status register | Allows dynamic configuration changes (e.g., latency tuning) without permanent register reprogramming |
| Internal ECC (1-bit correction) | Corrects single-bit errors on-the-fly during read, eliminating need for external error-handling logic |
| Program suspend/resume | Permits interrupt-driven firmware updates by pausing write/erase mid-operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L25645GMI-13G | Same density and Quad SPI interface; lacks internal ECC and program suspend | Requires external error detection logic; unsuitable for safety-critical boot paths | Select only when cost sensitivity outweighs reliability requirements and ECC can be implemented in host firmware |
| W25Q256JWSIQ | 256 Mbit with QPI; includes 4-KB parameter sectors but no uniform 256-B erase | Cannot perform atomic patching of small firmware modules without erasing larger blocks | Prefer for legacy designs requiring parameter-sector flexibility; avoid where fine-grained update is mandatory |
Compared with MX25L25645GMI-13G and W25Q256JWSIQ, S25FL256LAGNFB010 uniquely delivers uniform 256-byte erase plus internal ECC-critical for deterministic firmware update integrity in industrial and medical systems.

FAQ
What is the maximum operating temperature range for S25FL256LAGNFB010?
The device is rated for industrial temperature range of −40°C to +85°C. Its 20-year data retention specification is validated at 85°C, making it suitable for uncooled control cabinet deployments where thermal derating is required.
Does S25FL256LAGNFB010 support execute-in-place (XIP) mode?
Yes, it supports true XIP operation with zero-wait-state execution from linear address space. The device includes dedicated instruction cache and prefetch buffer to sustain 133 MHz clocked instruction fetches without CPU stall cycles.
How does the 256-byte uniform sector erase improve firmware update reliability?
It enables atomic patching of individual firmware modules without erasing unrelated code sections. This prevents partial corruption during power loss and eliminates need for redundant backup sectors, reducing total memory overhead by up to 30%.
Is S25FL256LAGNFB010 compatible with standard SPI controllers?
Yes, it operates in standard SPI mode (single I/O) at up to 80 MHz and supports all JEDEC JESD216B-defined command sets. Quad SPI mode requires host controller support for 0xEB and 0x6B fast-read opcodes with dummy cycles.
