Product details

Overview

S25FL128LAGBHM023 from Infineon is a 128-Mbit serial NOR flash memory with Quad SPI interface, 133 MHz clock frequency, and 3.0 V to 3.6 V supply voltage. It supports XIP (execute-in-place), dual/quad I/O protocols, and features 100K program/erase cycles with 20-year data retention - used in industrial PLC firmware storage and automotive ADAS boot code storage.

For engineers reviewing the S25FL128LAGBHM023 datasheet, S25FL128LAGBHM023 pinout, S25FL128LAGBHM023 application, or S25FL128LAGBHM023 equivalent, key selection criteria include Quad SPI timing compliance, sector protection granularity, erase suspend/resume capability, and AEC-Q100 Grade 2 qualification for automotive use cases.

Technical Context

This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O mode supporting single/dual/quad read/write operations. It uses a 64-byte page programming buffer and supports uniform 4-KB sectors and 64-KB blocks for flexible firmware partitioning.

The memory array is organized as 256 K × 16 bits, with hardware write protection via WP# pin and software-controlled sector lock-down. Erase suspend/resume enables background operation during critical system tasks without interrupting host execution.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	128 Mbit (16 MB) - sufficient for full boot image + recovery firmware in compact embedded systems
Interface	Quad SPI (x4 I/O) - enables 532 MB/s effective throughput at 133 MHz clock
Supply Voltage	3.0 V to 3.6 V - compatible with industrial 3.3 V rail without level-shifting
Erase Endurance	100,000 cycles per sector - supports frequent OTA update cycles in field-deployed devices
Data Retention	20 years at 85 °C - meets long-lifecycle requirements for automotive and industrial control units
Operating Temp	−40 °C to +105 °C - qualified for under-hood automotive and factory-floor industrial environments

Pinout & Package

Supplied in an 8-pin SOIC (208-mil) package with standard SPI pinout and hardware write-protect functionality.

Pin/Terminal	Circuit Role	Design Meaning
SO / IO1	Serial Output / Quad I/O Line 1	Bi-directional data line used for output during read and input during quad write
SI / IO0	Serial Input / Quad I/O Line 0	Primary input line for command/address/data; also serves as first quad I/O lane
WP#	Write Protect Input	Hardware-level sector protection enable when pulled low; overrides software lock commands
HOLD#	Hold Input	Pauses ongoing serial transfer without deselecting device - preserves bus state during host interrupts
CS#	Chip Select Input	Active-low enable for SPI communication; required assertion before any command sequence
CLK	Serial Clock Input	Master-generated clock up to 133 MHz; controls timing of all I/O transactions
VCC	Power Supply	3.0–3.6 V core and I/O supply; decoupling capacitor placement critical for noise immunity
GND	Ground	Reference return path for VCC and all signal pins; requires low-impedance PCB plane connection

Key Features

Feature	Design Value
Quad SPI x4 Mode	Enables 4-bit-per-clock data transfers, doubling bandwidth over dual I/O and quadrupling over standard SPI
Uniform 4-KB Sectors	Allows fine-grained firmware updates and secure boot partitioning without erasing entire 64-KB blocks
Erase Suspend/Resume	Permits host to pause erase operation, service high-priority interrupt, then resume - avoids timeout failures
AEC-Q100 Grade 2	Qualified for automotive applications requiring operation from −40 °C to +105 °C ambient
Security Register Lock	One-time programmable register prevents unauthorized reconfiguration of protection settings after initial setup

Applications

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 package but supports 166 MHz clock and octal DTR mode; lacks AEC-Q100 qualification	Targeted at high-performance computing and networking where speed > automotive qualification	Select when bandwidth > environmental qualification; verify host controller supports octal DTR timing
MX25L12833FZNI-10G	128 Mbit, 3.3 V, but only supports standard/dual SPI; no erase suspend or AEC-Q100 rating	Suitable for cost-sensitive consumer electronics with lower reliability requirements	Choose only for non-automotive, non-industrial applications where Quad SPI and endurance are not required

Compared with S25FL128SAGMFI001, this part trades peak bandwidth for automotive qualification and erase suspend; versus MX25L12833FZNI-10G, it adds Quad SPI, endurance, and temperature range at higher BOM cost - justifying use in safety-critical firmware storage.

FAQ

Is S25FL128LAGBHM023 pin-compatible with earlier S25FL128L variants?

Yes, it shares identical 8-pin SOIC (208-mil) mechanical footprint and SPI pin assignment with S25FL128LAGNFM000 and S25FL128LAGMFV000. No PCB redesign is needed for drop-in replacement, though firmware may require minor timing parameter updates due to enhanced Quad SPI performance.

Does this part support execute-in-place (XIP) mode?

Yes, S25FL128LAGBHM023 supports true XIP operation with zero-wait-state reads at up to 133 MHz in Quad SPI mode. The memory's internal address decoder and prefetch buffer enable direct CPU instruction fetch without local RAM buffering, reducing system memory footprint.

What is the purpose of the HOLD# pin beyond bus pausing?

HOLD# provides deterministic bus state preservation during external interrupts or power transients. When asserted, it halts all internal state machines without resetting command context - enabling immediate resumption post-interrupt, critical for real-time firmware update validation sequences.

How does the security register lock function impact field updates?

The security register lock is a one-time programmable (OTP) bit that disables further writes to protection registers after initial configuration. Once locked, sector protection settings become immutable - preventing accidental or malicious modification during field servicing while allowing normal program/erase operations on unlocked sectors.
