Product details

Overview

S25FL128LAGBHB020 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 in DDR mode. It operates across industrial temperature range (−40°C to +85°C) and supports XIP (execute-in-place) for microcontroller boot code storage in embedded systems.

For engineers reviewing the S25FL128LAGBHB020 datasheet, S25FL128LAGBHB020 pinout, S25FL128LAGBHB020 application, or S25FL128LAGBHB020 equivalent, key selection criteria include Quad SPI timing compliance, sector protection granularity, erase suspend/resume capability, and industrial-grade reliability for firmware storage in edge nodes and automotive ECUs.

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 configurable write protection via status register bits and hardware WP# pin.

It supports legacy SPI single/dual/quad I/O protocols and includes an internal 256-byte page buffer for accelerated programming. The memory array is organized as 16,384 pages of 256 bytes each, enabling efficient firmware update partitioning.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	128 Mbit (16 MB) - sufficient for full bootloader + application firmware image in resource-constrained MCUs
Interface	Quad SPI (QPI) - enables 4x data rate vs standard SPI, reducing firmware load time by ~75%
Read Speed	133 MHz DDR - delivers up to 66.5 MB/s effective throughput for XIP execution
Voltage Range	3.0 V to 3.6 V - compatible with standard 3.3 V logic rails and industrial power supplies
Operating Temp	−40°C to +85°C - qualified for under-hood automotive and industrial control environments
Erase Granularity	4 KB sectors / 64 KB blocks - allows fine-grained firmware patching without full chip erase
Write Protection	Hardware WP# pin + software status register lock - prevents accidental overwrite during field updates

Pinout & Package

Package: 8-pin SOIC (208-mil width), RoHS-compliant, surface-mountable with standard reflow profile.

Pin/Terminal	Circuit Role	Design Meaning
SO	Serial Output	Master-read data line in SPI/QPI modes; high-impedance when not selected
SI	Serial Input	Master-write data line; accepts command/address/data in all SPI modes
WP#	Write Protect	Active-low hardware lock; disables all write/erase commands when asserted
HOLD#	Hold Control	Pauses ongoing serial transfer without deselecting device; preserves state for multi-master arbitration
CS#	Chip Select	Active-low enable; initiates command decoding and powers internal logic on falling edge
SCLK	Serial Clock	Master-generated clock; synchronizes all I/O transfers up to 100 MHz (single) or 133 MHz (DDR)
VCC	Power Supply	3.0–3.6 V core voltage; decoupling capacitor required per JEDEC JESD62
GND	Ground	Reference return path; must be low-inductance connection to minimize switching noise

Key Features

Feature	Design Value
Erase Suspend/Resume	Allows interruption of bulk erase to service urgent read requests-critical for real-time firmware update scenarios
Program/Erase Cycle Endurance	100,000 cycles per sector-supports frequent over-the-air (OTA) firmware revisions in deployed devices
Security Register Lock	One-time programmable (OTP) lock bit prevents modification of security configuration after initial setup
Deep Power-Down Mode	1 µA typical standby current-enables ultra-low-power retention in battery-backed IoT endpoints
Quad Enable Bit	Configurable via status register; enables QPI mode only after explicit software initialization for robust protocol handshaking

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
S25FL128SAGMFI000	Same density and interface but in 8-pin WSON package (6×5 mm); no SOIC option	Better suited for space-constrained PCBs where SOIC footprint is prohibitive	Select when board area is critical and thermal profile permits WSON reflow
MX25L12833FZNI-10G	128 Mbit, 3V, but max clock 104 MHz (no DDR mode); lacks erase suspend	Lower cost for non-real-time firmware storage where update concurrency is not required	Choose for cost-sensitive consumer applications without OTA or safety-critical requirements

Compared with S25FL128SAGMFI000, this SOIC variant offers easier manual rework and legacy board compatibility; versus MX25L12833FZNI-10G, it delivers faster read throughput and deterministic erase interrupt handling essential for industrial firmware resilience.

FAQ

What is the maximum clock frequency supported in Quad SPI mode?

The S25FL128LAGBHB020 supports up to 100 MHz in standard Quad SPI mode and 133 MHz in DDR Quad SPI mode. These frequencies are specified under VCC = 3.0–3.6 V and industrial temperature conditions, with timing margins verified per JEDEC JESD22-A107 reliability testing.

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

Yes, the device supports XIP mode via continuous read commands, enabling direct CPU instruction fetch from flash without loading into RAM. This requires proper address mapping in the MCU's memory controller and alignment of code sections to 4-KB sector boundaries.

How is hardware write protection implemented?

Hardware write protection is controlled by the WP# pin: when pulled low, it disables all write, program, and erase operations regardless of status register settings. This provides fail-safe protection against firmware corruption during power transients or software faults.

Is deep power-down mode compatible with industrial temperature operation?

Yes, deep power-down mode is fully characterized from −40°C to +85°C, with typical current draw of 1 µA and wake-up time of ≤100 µs. Recovery is initiated by CS# deassertion followed by a valid command sequence.
