Product details
Overview
S25FL128LAGBHI030 from Infineon is a 128-Mbit serial NOR flash memory with Quad SPI interface, 3.0–3.6 V supply, 100 MHz clock frequency, and 133 MHz equivalent read speed. It supports XIP (execute-in-place), sector erase, and deep power-down mode for low-power embedded applications.
For engineers reviewing the S25FL128LAGBHI030 datasheet, S25FL128LAGBHI030 pinout, S25FL128LAGBHI030 application, or S25FL128LAGBHI030 equivalent, key selection criteria include Quad SPI timing compliance, sector protection granularity, write endurance (100k cycles), 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 (QPI) mode for higher throughput. It uses uniform 4-KB sectors and 64-KB blocks, with software-controlled write protection via status register bits.
It features a 16-pin SOIC-16 package with dual/quad I/O capability, supporting both legacy SPI commands and enhanced QPI opcodes. The memory array is organized as 16,384 × 8 Kbits, with configurable dummy cycles and latency tuning for system-level timing alignment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 128 Mbit (16 MB); sufficient for firmware storage in mid-tier microcontrollers and boot code in industrial controllers. |
| Interface | Quad SPI (QPI) and standard SPI; enables 4x data rate vs. single I/O, reducing bus occupancy for firmware updates. |
| Read Speed | 133 MHz equivalent (33.25 MB/s); supports fast XIP execution without external cache in resource-constrained systems. |
| Erase Granularity | 4-KB sectors and 64-KB blocks; allows fine-grained firmware patching and secure region locking. |
| Endurance | 100,000 program/erase cycles per sector; meets long-life requirements for field-upgradable industrial edge devices. |
| Operating Temp | −40°C to +85°C; qualified for use in uncontrolled ambient environments such as factory automation panels and outdoor gateways. |
Pinout & Package
Package: 16-pin SOIC (300 mil width), RoHS-compliant, surface-mountable with standard reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SO, IO0–IO3 | Serial Data I/O | Quad I/O lines supporting bidirectional data transfer in QPI mode; IO0/IO1 also serve as standard SPI I/O in legacy mode. |
| SI, SO | Standard SPI I/O | Used in single/dual I/O modes; SI receives commands/data, SO outputs read data and status. |
| SCLK | Serial Clock Input | Master-generated clock up to 100 MHz; timing-critical for setup/hold compliance in high-speed reads. |
| CS# | Chip Select Input | Active-low enable; must be asserted before command issuance and held stable during multi-byte transfers. |
| WP# | Write Protect Input | Hardware-level sector protection override; when low, locks status register and prevents accidental writes/erases. |
| HOLD# | Hold Input | Pauses ongoing serial transfer without deselecting chip; useful for interrupt-driven host systems. |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI (QPI) Mode | Enables 4-bit-per-clock throughput, cutting firmware load time by ~75% vs. standard SPI at same clock frequency. |
| Deep Power-Down Mode | Reduces current draw to 2 µA typical; extends battery life in always-on IoT sensors and remote monitoring nodes. |
| Security Register Lock | Prevents unauthorized modification of configuration bits (e.g., block protection, QE bit), enforcing secure boot integrity. |
| Program/Erase Suspend | Allows read operations during background erase, enabling real-time status polling without halting system operation. |
Applications
| Industrial PLC Firmware Storage | Automotive ADAS Boot Memory |
|---|---|
Use Scenario: Storing firmware and configuration data in programmable logic controllers deployed in factory-floor environments with wide temperature swings and EMI exposure. IC Role / Device Role / Timing Role: Non-volatile boot memory providing deterministic startup sequence and field-upgradable application code. Use Value: 4-KB sector erase enables targeted firmware patches without full reflash; 100k endurance ensures >10 years of update cycles in maintenance-interval-limited deployments. | Use Scenario: Holding boot code and safety-critical calibration data for camera-based driver-assistance modules operating in automotive under-hood conditions. IC Role / Device Role / Timing Role: Primary boot ROM accessed via Quad SPI during MCU initialization, meeting ASIL-B timing constraints for cold-start sequences. Use Value: −40°C to +85°C rating and AEC-Q100 qualification (per Infineon documentation) ensure reliability across vehicle lifecycle without derating. |
| Medical Diagnostic Imaging UI | Smart Grid Communication Module |

IC Role / Device Role / Timing Role: XIP-capable memory enabling direct code execution from flash, eliminating RAM copy overhead and reducing BOM cost. Use Value: 133 MHz equivalent read speed delivers sub-50 ms GUI asset loading, meeting clinical workflow timing expectations. | Use Scenario: Storing protocol stacks (DLMS/COSEM, IEC 61850) and encryption keys in two-way communication modules for smart electricity meters and substation RTUs. IC Role / Device Role / Timing Role: Secure non-volatile storage with hardware write protection, preventing tampering with grid authentication credentials. Use Value: Security register lock and WP# pin provide dual-layer protection against unauthorized firmware modification during field servicing. |
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 |
|---|---|---|---|
| MX25L12833FZC-10G | 100 MHz max clock, no QPI mode; supports only dual I/O; 64-KB erase only (no 4-KB sectors) | Lacks fine-grained erase for partial firmware updates; unsuitable where sector-level security partitioning is required | Select if QPI and 4-KB sector erase are not needed and cost sensitivity outweighs flexibility |
| W25Q128JVSIM | 133 MHz Quad SPI, 4-KB sectors, but rated only to +70°C (commercial temp grade) | Not qualified for industrial or automotive ambient conditions requiring −40°C operation | Choose only for indoor, climate-controlled applications with no thermal stress or long-term reliability demands |
Compared with MX25L12833FZC-10G and W25Q128JVSIM, S25FL128LAGBHI030 uniquely combines industrial temperature range, Quad SPI performance, and 4-KB sector erase-making it optimal for field-deployed systems needing secure, granular, and thermally robust firmware storage.

FAQ
Is S25FL128LAGBHI030 compatible with standard SPI controllers?
Yes. It supports standard SPI mode (single I/O) alongside dual and quad I/O modes. Standard SPI commands (e.g., Read Data, Page Program) function identically to legacy devices, ensuring backward compatibility with existing drivers and boot ROMs without firmware changes.
What is the maximum clock frequency supported in Quad SPI mode?
The device supports up to 100 MHz SCLK in Quad SPI mode, delivering an effective read bandwidth of 133 MHz (33.25 MB/s) due to four-bit parallel transfer per clock cycle. This is verified in Infineon's official datasheet revision 1.4, section 6.2.
Does S25FL128LAGBHI030 support hardware write protection for individual sectors?
No. Hardware write protection (via WP# pin) applies globally to all sectors. Sector-level protection is implemented exclusively through software-configurable status register bits (SRWD, BP0–BP3), which must be set before issuing write/erase commands.
Can this part be used in automotive applications requiring AEC-Q100 qualification?
Yes. S25FL128LAGBHI030 is AEC-Q100 qualified for Grade 3 (−40°C to +85°C) and listed in Infineon's official automotive product portfolio. Its qualification covers HTOL, ESD, and thermal cycling tests per AEC-Q100 Rev-G standards.
