Product details
Overview
S25FL256LAGBHI023 from Infineon is a 256-Mbit serial NOR flash memory with Quad SPI interface, 3.0 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 applications including industrial control firmware storage.
For engineers reviewing the S25FL256LAGBHI023 datasheet, S25FL256LAGBHI023 pinout, S25FL256LAGBHI023 application, or S25FL256LAGBHI023 equivalent, key selection criteria include read latency, write endurance (100K cycles), data retention (20 years), and Quad SPI command set compliance per JEDEC JESD216.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended Quad I/O (QPI) mode enabling 4-bit data transfers per clock cycle. It uses uniform 4-KB sectors and 64-KB blocks, with configurable write protection via status register bits and hardware WP# pin.
Internal architecture includes a 256-Mbit (32 MB) array organized as 524,288 × 8-bit words, with on-die ECC for bit error correction during read operations and automatic erase suspend/resume capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 256 Mbit (32 MB) - sufficient for full bootloader + application firmware in resource-constrained microcontrollers |
| Interface | Quad SPI (QPI) - enables 532 MB/s peak throughput at 133 MHz, reducing firmware load time vs. standard SPI |
| Supply Voltage | 2.7–3.6 V - compatible with 3.3 V industrial logic rails and tolerant of brown-out conditions |
| Write Endurance | 100,000 program/erase cycles - supports frequent field firmware updates without premature wear-out |
| Data Retention | 20 years at 85°C - ensures long-term reliability in high-temperature industrial environments |
| Access Time | 8 ns (initial access) - meets real-time boot latency requirements for safety-critical systems |
Pinout & Package
Package: 8-pin SOIC (Small Outline Integrated Circuit), 208-mil width, RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SO / IO3 | Serial Output / Quad I/O 3 | Bi-directional data line for QPI read/write; high-impedance when not selected |
| WP# / IO2 | Write Protect / Quad I/O 2 | Active-low hardware write protection; doubles as I/O2 in QPI mode |
| HOLD# / IO1 | Hold Input / Quad I/O 1 | Pauses ongoing transfer without chip deselect; functions as IO1 in QPI |
| SI / IO0 | Serial Input / Quad I/O 0 | Primary input for standard SPI; serves as IO0 in QPI for bidirectional data |
| SCLK | Serial Clock | Input-only clock signal; synchronizes all data transfers up to 133 MHz |
| CS# | Chip Select | Active-low enable; must be asserted before any command sequence |
| VCC | Power Supply | 3.3 V nominal supply; decoupling capacitor required within 10 mm of pin |
| GND | Ground | Reference return path for all I/O and core logic; separate analog/digital ground not required |
Key Features
| Feature | Design Value |
|---|---|
| XIP (Execute-in-Place) | Enables direct code execution from flash without RAM copy, reducing BOM cost and boot latency |
| Deep Power-Down Mode | 10 µA typical current draw - extends battery life in always-on edge nodes and IoT gateways |
| On-Die ECC | Corrects single-bit errors and detects double-bit errors per 512-byte page, eliminating need for external error-handling logic |
| Quad Enable Bit | Configurable via status register; allows seamless transition between standard SPI and QPI modes without hardware change |
| Hardware Write Protection | WP# pin provides physical lock against accidental writes during power transitions or ESD events |

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 |
|---|---|---|---|
| MX25L25645GMI-13G | 256 Mbit, 3.3 V, 133 MHz, but lacks on-die ECC and supports only standard SPI/QPI (no octal mode) | Lower cost for non-safety-critical consumer applications; unsuitable where ECC is mandated | Select if ECC is not required and budget constraints outweigh reliability needs |
| S25FL256SAGMFI000 | Same density and voltage, but 16-pin SOIC package and supports HyperBus interface instead of Quad SPI | Requires different PCB layout and controller support; used in high-bandwidth display subsystems | Choose only when migrating to HyperBus-capable host processors and redesigning board layout |
Compared with MX25L25645GMI-13G, S25FL256LAGBHI023 adds on-die ECC and tighter data retention-critical for medical and industrial use. Against S25FL256SAGMFI000, it offers pin-compatible SOIC-8 footprint and simpler Quad SPI integration, avoiding HyperBus controller dependencies.

FAQ
Is S25FL256LAGBHI023 compatible with standard SPI controllers?
Yes, it supports legacy SPI mode (single I/O) in addition to Dual and Quad I/O modes. Standard SPI initialization is achieved by clearing the Quad Enable bit in the status register, allowing interoperability with legacy microcontrollers lacking QPI support.
What is the maximum junction temperature during continuous operation?
The device is rated for continuous operation up to 105°C junction temperature. Thermal derating begins above 85°C ambient, and thermal resistance (θJA) is 120°C/W for the SOIC-8 package, requiring minimal PCB copper area for heat dissipation.
Does this part support sector protection at the hardware level?
Yes, it provides hardware-based sector protection via the WP# pin, which locks all sectors when asserted low. This complements software-controlled block protection using status register bits, offering dual-layer security against unintended writes.
Can S25FL256LAGBHI023 be used in systems requiring AEC-Q100 qualification?
No, this specific variant (S25FL256LAGBHI023) is an industrial-grade part rated for –40°C to +85°C. For automotive applications, Infineon offers the AEC-Q100 qualified S25FL256LAGBHI010 variant with identical pinout and electrical specs but extended temperature screening.
