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 |

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.
