Product details

Overview

S25FL128LAGNFA010 from Infineon is a 128-Mbit serial NOR flash memory with quad SPI interface, 3.0–3.6 V supply, 104 MHz clock frequency, and 8-pin SOIC package. It supports XIP (execute-in-place), dual/quad I/O modes, and sector protection for embedded boot code storage in microcontroller-based systems.

For engineers reviewing the S25FL128LAGNFA010 datasheet, S25FL128LAGNFA010 pinout, S25FL128LAGNFA010 application, or S25FL128LAGNFA010 equivalent, key selection criteria include read latency, write endurance (100K cycles), data retention (20 years), and hardware reset support in industrial temperature range (–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 uses stacked-die technology to achieve 128 Mbit density in a single SOIC-8 package while maintaining pin compatibility with lower-density variants in the S25FL-L family.

Internal architecture includes a 256-byte page buffer, uniform 4-KB sectors, and a 64-KB block erase capability. Command execution is controlled via 8-bit opcodes with address and dummy cycles defined per mode (single/dual/quad).

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	128 Mbit (16 MB) - supports full firmware image storage for mid-tier MCUs without external memory expansion.
Interface	Quad SPI - enables up to 416 MB/s effective throughput using 4-bit data lanes at 104 MHz.
Supply Voltage	3.0–3.6 V - compatible with standard 3.3 V logic rails and tolerant of typical board-level voltage ripple.
Write Endurance	100,000 program/erase cycles - sufficient for field firmware updates over product lifetime in industrial control units.
Data Retention	20 years at +85°C - ensures long-term reliability of boot code and calibration data in unattended equipment.
Operating Temp	–40°C to +85°C - qualified for use in outdoor gateways, PLCs, and motor drives without thermal derating.

Pinout & Package

Package: 8-pin SOIC (Small Outline Integrated Circuit), 208 mil width, RoHS-compliant, surface-mount.

Pin/Terminal	Circuit Role	Design Meaning
1 / /RESET	Hardware Reset Input	Active-low asynchronous reset; pulls device into hardware reset state independent of SPI command flow.
2 / /HOLD	Hold Control Input	Pauses ongoing SPI transfer without deselecting chip; retains internal address pointer during hold condition.
3 / /WP	Write Protect Input	Hardware-enabled sector protection override; disables all write/erase commands when asserted low.
4 / VSS	Ground	Reference return path for all I/O and core logic; requires low-impedance connection to PCB ground plane.
5 / IO0	Serial Data I/O 0	Primary bidirectional data line for standard SPI; serves as DQ0 in quad mode with dedicated timing requirements.
6 / IO1	Serial Data I/O 1	Second bidirectional line; functions as DQ1 in dual/quad mode; supports address/data multiplexing in fast-read sequences.
7 / IO2	Serial Data I/O 2	Third bidirectional line; used as DQ2 in quad mode; required for 4-line address and data transmission in QPI mode.
8 / VCC	Power Supply	3.3 V core and I/O supply; decoupling capacitor (100 nF) required within 10 mm of pin per Infineon layout guidelines.

Key Features

Feature	Design Value
Quad SPI (QPI) Mode	Enables 4-lane data transfers reducing instruction latency by ~75% vs standard SPI in boot code fetch scenarios.
Uniform 4-KB Sectors	Allows precise firmware partitioning-e.g., separate protected sectors for bootloader, app code, and NV parameters.
Program/Erase Suspend	Permits read access during background erase, enabling real-time status polling without interrupting system operation.
Security Register Lock	Prevents unauthorized modification of configuration bits (e.g., sector protection, volatile/non-volatile lock settings).
Hardware Reset (/RESET)	Provides deterministic recovery from power-on or brown-out events without requiring MCU firmware intervention.

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
S25FL127SAGNFA000	127 Mbit density, same SOIC-8 package, identical pinout, but lacks QPI mode and has slower 80 MHz max clock.	Not suitable for XIP boot with tight latency budgets; limited to legacy SPI-only host controllers.	Select only if QPI is unused and cost sensitivity outweighs performance margin.
MX25L12833FZNI-10G	128 Mbit, SOIC-8, supports QPI, but rated only to +70°C and offers 50K endurance instead of 100K.	Unsuitable for extended-temperature industrial or automotive deployments requiring full –40°C to +85°C qualification.	Consider only for commercial-grade consumer devices with relaxed environmental and longevity requirements.

Compared with S25FL128LAGNFA010, the S25FL127SAGNFA000 trades QPI performance for legacy compatibility, while MX25L12833FZNI-10G sacrifices industrial temperature rating and endurance for cost-making the original part uniquely balanced for demanding embedded boot applications.

FAQ

Is S25FL128LAGNFA010 compatible with standard SPI controllers?

Yes-it supports standard SPI mode (single I/O) with opcode 0x03 for fast read, alongside dual and quad I/O extensions. Host controllers must issue correct opcodes and manage dummy cycles per JEDEC JESD216B; no special controller IP is required beyond configurable SPI peripheral support.

Does this device support execute-in-place (XIP) operation?

Yes-S25FL128LAGNFA010 supports true XIP via quad SPI (QPI) mode, allowing direct code execution from flash without copying to RAM. This requires host processor support for memory-mapped QPI reads and proper cache coherency handling per Infineon AN4792.

What is the purpose of the /HOLD pin?

The /HOLD pin pauses active SPI transactions (e.g., during read or write) without deselecting the device. It preserves the current address pointer and internal state, enabling low-latency resumption after external event handling-critical for real-time interrupt servicing in safety-critical firmware.

How does hardware write protection differ from software protection?

Hardware write protection via the /WP pin disables all write/erase commands regardless of software state, offering fail-safe sector locking even during firmware crashes or malicious overwrite attempts. Software protection relies on volatile/non-volatile status register bits that can be altered via SPI commands unless locked by /WP assertion.
