Product details

Overview

S25FL128LAGBHI020 from Infineon is a 128-Mbit serial NOR flash memory with Quad SPI interface, 3.0–3.6 V supply voltage, 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 including industrial controllers and IoT edge nodes.

For engineers reviewing the S25FL128LAGBHI020 datasheet, S25FL128LAGBHI020 pinout, S25FL128LAGBHI020 application, or S25FL128LAGBHI020 equivalent, key selection criteria include Quad SPI timing compliance, sector protection granularity, deep power-down current (10 µA typical), and JEDEC-standard 8-pin SOIC package compatibility.

Technical Context

This device implements a standard SPI-compatible command set extended for Quad I/O operation, supporting single/dual/quad read and program commands. It features a 256-byte page programming buffer and uniform 4-KB sector erase architecture aligned to JEDEC JESD216B.

Internal write state machine handles erase and program operations autonomously, reducing host CPU overhead. The memory array is organized as 256 Kbytes × 64 bits, with hardware write protection via WP# pin and software-controlled block protection registers.

Key Specifications

Memory Density	128 Mbit (16 Mbyte) - supports firmware images up to ~15 MB with margin for OTA updates
Interface	Quad SPI - enables 400 MB/s peak read bandwidth using four data lines simultaneously
Read Speed	133 MHz equivalent - achieves 66.5 MB/s sustained sequential read in QSPI mode
Supply Voltage	3.0–3.6 V - compatible with standard 3.3 V logic rails and industrial power supplies
Deep Power-Down Current	10 µA typical - extends battery life in always-on sensor nodes during idle periods
Erase Granularity	4 KB uniform sectors - allows fine-grained firmware partitioning and secure over-the-air update rollback

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 quad read/write; high-impedance when not selected
SI / IO0	Serial Input / Quad I/O 0	Primary data input for commands and write data; also serves as first quad data line
WP# / IO2	Write Protect / Quad I/O 2	Hardware-level sector lock control; active-low; doubles as quad data line in I/O mode
HOLD# / IO1	Hold Input / Quad I/O 1	Pauses ongoing serial transfer without deselecting device; doubles as quad data line
CS#	Chip Select	Active-low enable signal; initiates command decoding and I/O activity on rising edge
CLK	Serial Clock	Master-generated clock up to 100 MHz; controls timing of all I/O transfers
VCC	Power Supply	3.0–3.6 V core and I/O supply; decoupling capacitor required per datasheet layout guidelines
GND	Ground	Reference return path for all signals and power; must be low-impedance connection

Key Features

Feature	Design Value
Quad SPI with wrap-around burst	Enables continuous 4-byte address incrementing across page boundaries without command reissue
Hardware reset via RESET# pin	Provides synchronous, deterministic recovery from unknown states without power cycle
One-time programmable (OTP) security register	Stores 1024-bit user-defined keys or configuration locks, permanently fused after programming
JEDEC JESD216B SFDP support	Allows automatic configuration by host bootloader via standardized parameter table read at boot
Program/Erase suspend-resume	Permits interrupting background erase or program to service time-critical reads, then resume

Applications

Industrial PLC Firmware Storage

Use Scenario: Storing firmware and configuration data in programmable logic controllers operating in harsh temperature environments (−40°C to +85°C).

IC Role / Device Role / Timing Role: Non-volatile code storage with XIP capability enabling direct execution from flash, reducing external RAM footprint.

Use Value: Sector protection prevents accidental overwrite during field firmware updates; deep power-down minimizes standby energy in unpowered modules.

Use Scenario: Holding boot loader and safety-critical initialization code for camera and radar processing units in Level 2+ ADAS systems.

IC Role / Device Role / Timing Role: Primary boot memory mapped into processor address space; supports fast quad read for sub-100 ms cold boot timing.

Use Value: 4 KB erase sectors allow independent update of boot loader vs. application partitions; OTP register secures cryptographic keys against tampering.

Medical Imaging Device Configuration

Smart Grid Communication Module

Use Scenario: Retaining calibration tables, device-specific parameters, and regulatory compliance logs in portable ultrasound and ECG equipment.

IC Role / Device Role / Timing Role: Parameter storage with hardware write protection (WP#) ensuring integrity during battery-backed operation.

Use Value: 10 µA deep power-down current preserves backup battery life for >5 years; SFDP enables auto-adaptation to host controller revisions.

Use Scenario: Storing protocol stacks (DLMS/COSEM, IEC 61850) and firmware for wireless HAN (Home Area Network) gateways in smart meters.

IC Role / Device Role / Timing Role: Dual-role memory: boot code storage and runtime parameter logging with wear leveling handled by host MCU.

Use Value: Uniform 4 KB sectors simplify file system partitioning; suspend/resume enables real-time packet handling during flash writes.

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
S25FL128SAGMFI001	Same density and SOIC-8 package but uses 1.8 V core supply (1.7–2.0 V); different pinout for VIO/VCC separation	Targeted for ultra-low-power microcontrollers with dual-voltage I/O domains; not drop-in compatible due to supply rail mismatch	Select only if host system provides separate 1.8 V I/O supply and requires lower active current
MX25L12833FZNI-10G	128 Mbit, SOIC-8, 3 V supply, but lacks SFDP support and OTP register; max clock 80 MHz	Suitable for cost-sensitive consumer applications where bootloader auto-configuration and secure key storage are unnecessary	Choose when BOM cost is prioritized over configurability and security features

Compared with S25FL128SAGMFI001, this part avoids dual-supply complexity and ensures full 3.3 V compatibility; versus MX25L12833FZNI-10G, it delivers faster read throughput, standardized configuration, and hardware security-critical for industrial and automotive firmware integrity.

FAQ

Is S25FL128LAGBHI020 compatible with standard SPI controllers?

Yes, it supports standard SPI modes (0,3) for legacy single-I/O operation while offering enhanced performance in dual and quad modes. Command sets are backward-compatible with earlier Spansion/Infineon serial flash devices, allowing reuse of existing driver stacks with minor configuration updates for QSPI enablement.

What is the endurance rating and data retention specification?

The device guarantees 100,000 program/erase cycles per sector and 20-year data retention at 85°C. These values are validated per JEDEC JESD22-A117 and JESD22-A108 standards and apply across the full industrial temperature range (−40°C to +85°C) without derating.

Does it support execute-in-place (XIP) operation?

Yes, XIP is fully supported via Quad SPI continuous read mode with wrap-around burst. The internal address counter automatically increments across 4-byte boundaries, enabling seamless instruction fetch without host intervention or address retransmission between bursts.

How is hardware write protection implemented?

Hardware write protection is controlled by the WP# pin: when driven low, it locks all sectors except those enabled by software configuration. Protection granularity includes individual 4 KB sectors, top/bottom 64 KB blocks, and full array lock, configurable via status register bits SRWD, BP0–BP3, and TB/BP3.
