Product details
Overview
S25FL128LAGMFB013 from Infineon is a 128-Mbit serial NOR flash memory with quad SPI interface, 3.0 V supply voltage, and 100 MHz clock frequency, supporting XIP (execute-in-place) operation in automotive-grade applications.
For engineers reviewing the S25FL128LAGMFB013 datasheet, S25FL128LAGMFB013 pinout, S25FL128LAGMFB013 application, or S25FL128LAGMFB013 equivalent, key selection criteria include automotive temperature range (−40°C to +125°C), sector-erase capability, hardware reset support, and JEDEC JESD216-compliant SFDP table for configuration auto-detection.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O (QPI) mode for high-speed data transfer. It uses a 64-MB address space organized into 256 uniform 64-KB sectors and supports both 4-KB and 64-KB erase granularity.
The memory integrates a hardware write-protect (WP#) pin and software-controlled protection via status register bits. It complies with AEC-Q100 Grade 2 qualification and supports single, dual, and quad read commands with configurable dummy cycles per JEDEC standard.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 128 Mbit (16 MB) - sufficient for boot code, firmware images, and parameter storage in ECUs |
| Interface | Quad SPI (QPI) - enables up to 400 MB/s effective throughput using four I/O lines simultaneously |
| Supply Voltage | 2.7 V to 3.6 V - compatible with automotive 3.3 V rail with margin for transient variation |
| Operating Temperature | −40°C to +125°C - qualified per AEC-Q100 Grade 2 for under-hood ECU use |
| Erase Granularity | 4 KB and 64 KB sectors - allows fine-grained firmware updates without full chip erase |
| Write Cycle Endurance | 100,000 program/erase cycles - supports field firmware updates over vehicle lifetime |
| Data Retention | 20 years at 125°C - ensures long-term reliability in high-temp automotive environments |
Pinout & Package
Supplied in an 8-pin SOIC (Small Outline Integrated Circuit) package with 208-mil body width and gull-wing leads. Pin pitch is 1.27 mm, compliant with JEDEC MS-012AC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SO/IO1 | Serial Output / Quad I/O Line 1 | Bi-directional data line used for output in standard SPI and bidirectional I/O in QPI mode |
| SI/IO0 | Serial Input / Quad I/O Line 0 | Input-only in standard SPI; bidirectional in QPI; carries command/address/data |
| WP#/IO2 | Write Protect / Quad I/O Line 2 | Hardware-level write inhibition when asserted low; functions as I/O2 in QPI |
| HOLD#/IO3 | Hold Input / Quad I/O Line 3 | Pauses ongoing serial transfer without deselecting device; acts as I/O3 in QPI |
| CS# | Chip Select | Active-low enable signal; initiates command sequence on falling edge |
| CLK | Serial Clock | Master-generated clock synchronizing all SPI/QPI transfers; max 100 MHz |
| VCC | Power Supply | 3.3 V nominal supply; decoupling required within 10 mm of pin |
| VSS | Ground | Reference return path for all I/O and core logic; must be low-impedance |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI (QPI) Mode | Enables 4-bit-per-clock data transfer, doubling bandwidth vs. standard SPI without increasing clock frequency |
| Hardware Reset (RST#) | Dedicated active-low pin allowing full device state recovery independent of SPI command flow |
| JEDEC JESD216 SFDP | Enables automatic configuration detection by host controller, eliminating hard-coded timing parameters |
| Secure Silicon Sector | One-time-programmable 512-byte sector for storing cryptographic keys or unique identifiers |
| Program/Erase Suspend | Allows read access during background erase or program operations, enabling real-time interrupt handling |

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 |
|---|---|---|---|
| CY15B104QN-PSOC | 4-Mbit density, FRAM-based, unlimited endurance, but lacks QPI mode and SFDP | Better for frequent data logging; unsuitable for XIP firmware storage due to lower density | Select only when byte-level write endurance >1012 cycles is required and firmware size ≤4 Mbit |
| MX25L12833FZNI-10G | Same 128-Mbit density and SOIC-8 package, but industrial temp range (−40°C to +85°C) and no AEC-Q100 qualification | Acceptable for non-automotive infotainment or gateway modules where extended temp not needed | Choose for cost-sensitive non-safety applications where automotive qualification is not mandated |
Compared with CY15B104QN-PSOC and MX25L12833FZNI-10G, the S25FL128LAGMFB013 uniquely combines automotive qualification, quad SPI bandwidth, and SFDP configurability-making it the only option among the three qualified for ASIL-B–related ECU firmware storage.

FAQ
Is S25FL128LAGMFB013 pin-compatible with earlier S25FL128S variants?
Yes, it shares identical SOIC-8 pinout and electrical interface with S25FL128SAGMFI001 and S25FL128SAGMFI013. However, the LAGMFB013 adds enhanced ECC coverage and updated SFDP revision v1.6, requiring minor host driver updates for optimal error correction behavior.
Does this device support octal DTR mode?
No. The S25FL128LAGMFB013 supports only standard SPI, dual I/O, and quad I/O (QPI) modes. Octal DTR capability is introduced in later-generation Infineon EXCELON-F family devices such as the S26KL128SDPBH200.
What is the purpose of the Secure Silicon Sector?
The Secure Silicon Sector is a one-time-programmable 512-byte region used to store immutable values like cryptographic keys, device-specific identifiers, or anti-tamper signatures. Once programmed, it cannot be erased or rewritten, providing hardware-rooted security for firmware authentication.
Can S25FL128LAGMFB013 operate at 1.8 V?
No. This variant is specified exclusively for 2.7–3.6 V operation. Infineon offers the S25FL128LAGNFM010 for 1.8 V systems, which uses a different internal charge pump architecture and is not functionally or pin-compatible with the 3.0 V S25FL128LAGMFB013.
