Product details
Overview
S25FL128LAGNFB013 from Infineon Technologies is a 128-Mbit serial NOR flash memory with Quad SPI interface, 3.0 V supply voltage, and 100 MHz clock frequency. It supports XIP (execute-in-place), dual/quad I/O protocols, and offers 100K program/erase cycles with 20-year data retention.
For engineers reviewing the S25FL128LAGNFB013 datasheet, S25FL128LAGNFB013 pinout, S25FL128LAGNFB013 application, or S25FL128LAGNFB013 equivalent, key selection criteria include Quad SPI timing compliance, sector protection granularity, write suspend/resume capability, and industrial temperature range operation (-40°C to +85°C).
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O commands compliant with JEDEC JESD216B. It integrates a 256-byte page write buffer and supports uniform 4-KB sectors and 64-KB blocks for flexible firmware partitioning.
The memory array is organized as 256 Kbytes × 8 bits, with erase suspend/resume functionality enabling background operations during real-time system execution. Internal ECC logic corrects single-bit errors and detects double-bit errors per 512-byte sector.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 128 Mbit (16 MB) - sufficient for full boot code, firmware image, and configuration storage in embedded controllers |
| Interface | Quad SPI (x4 I/O) - enables up to 400 MB/s effective throughput using 100 MHz clock and 4-bit data bus |
| Supply Voltage | 2.7–3.6 V - compatible with 3.3 V rail and tolerant of typical industrial power rail variation |
| Operating Temperature | -40°C to +85°C - qualified for industrial-grade deployment without derating |
| Erase Cycles | 100,000 per sector - supports frequent field firmware updates over product lifetime |
| Data Retention | 20 years at 85°C - ensures long-term reliability in thermally stressed environments |
| Write Protection | Software-controlled top/bottom 64 KB, 32 KB, 16 KB, 8 KB, 4 KB sectors - enables secure bootloader and parameter partitioning |
Pinout & Package
Package: 16-pin SOIC (300 mil, GNFB suffix), RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SO | Serial Output | Master-in/slave-out data line for standard and quad SPI read operations |
| SI | Serial Input | Master-out/slave-in data line for standard SPI writes and command input |
| WP# | Write Protect | Hardware-enabled sector protection; low-active signal disables program/erase in protected regions |
| HOLD# | Hold | Pauses ongoing serial transfer without deselecting device; maintains internal state during host interruption |
| CS# | Chip Select | Active-low enable for SPI command decoding and I/O activation |
| SCLK | Serial Clock | Input clock synchronizing all SPI transactions; max 100 MHz for quad mode |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI x4 I/O Mode | Enables 4-bit parallel data transfer per clock cycle, doubling bandwidth versus dual I/O and quadrupling versus standard SPI |
| Erase Suspend/Resume | Allows host to pause block erase and resume later-critical for real-time systems requiring deterministic latency |
| Internal ECC | Single-bit correction and double-bit detection per 512-byte sector reduces need for external error management logic |
| Flexible Sector Protection | Configurable software lock-down of 4 KB to 64 KB regions prevents accidental overwrite of bootloader or calibration data |
| XIP Support | Enables direct code execution from flash via memory-mapped interface, reducing RAM footprint in resource-constrained MCUs |

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 |
|---|---|---|---|
| S25FL128SAGNFI000 | Same density and package but with 1.8 V core supply (dual VCC/VIO); lacks industrial temp grade (only commercial -20°C to +70°C) | Targeted at low-power portable electronics, not industrial or automotive deployments | Select only if system uses 1.8 V I/O and operates within commercial temperature range |
| MX25L12833FZNI-10G | 128 Mbit, 3 V, SOIC-16, but rated for -40°C to +105°C and supports DTR (double-transfer-rate) mode | Supports extended high-temp operation and higher bandwidth in DTR mode; no built-in ECC | Prefer when ambient exceeds 85°C or DTR timing is required; add external ECC if needed |
Compared with S25FL128SAGNFI000, this part delivers guaranteed industrial temperature operation and integrated ECC; compared with MX25L12833FZNI-10G, it trades extended high-temp margin for on-die error correction-critical where bit integrity outweighs peak thermal tolerance.

FAQ
What is the maximum clock frequency supported in Quad SPI mode?
The S25FL128LAGNFB013 supports up to 100 MHz in Quad SPI mode, delivering an effective data rate of 400 MB/s (100 MHz × 4 bits). This timing is validated across the full industrial temperature range and requires proper PCB layout with matched trace lengths and controlled impedance for all four I/O lines.
Does this device support execute-in-place (XIP) operation?
Yes, the device supports XIP via memory-mapped Quad SPI interface. When enabled, the host processor fetches instructions directly from flash without loading into RAM, reducing boot time and memory footprint. XIP requires compatible MCU support and proper configuration of the flash's continuous read mode.
How is sector protection implemented-hardware or software?
Sector protection uses both hardware and software methods: WP# pin provides hardware-level lock for top/bottom 64 KB regions, while software commands configure fine-grained protection for 4 KB to 64 KB sectors. Both mechanisms are non-volatile and persist across power cycles.
Is internal ECC enabled by default after power-on?
Yes, internal ECC is always active and cannot be disabled. It automatically corrects single-bit errors and reports double-bit errors per 512-byte sector during read operations. No initialization or register setting is required-the logic operates transparently to the host controller.
