Product details
Overview
S25FL128LAGMFM003 from Infineon is a 128-Mbit serial NOR flash memory with quad SPI interface, 3.0 V supply voltage, and 100 MHz clock frequency. It supports XIP (execute-in-place), dual/quad I/O modes, and offers 100,000 program/erase cycles with 20-year data retention.
For engineers reviewing the S25FL128LAGMFM003 datasheet, S25FL128LAGMFM003 pinout, S25FL128LAGMFM003 application, or S25FL128LAGMFM003 equivalent, key selection criteria include quad SPI timing compliance, sector protection granularity, erase suspend/resume capability, and industrial temperature range operation.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O commands compliant with JEDEC JESD216B. It uses a 64-Mbit × 2 stacked-die architecture to achieve 128 Mbit density in an 8-pin SOIC package.
Internal architecture includes a 256-byte page buffer, uniform 4-KB sectors, and a 64-KB block structure. Command execution supports fast read at 100 MHz with 8- or 16-bit dummy cycles depending on mode.

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 command sequence |
| 2 / /HOLD | Hold control input | Pauses ongoing serial transfer without losing internal address or state; used for bus arbitration |
| 3 / /WP | Write protect input | Hardware-enabled sector protection; disables program/erase when asserted low |
| 4 / VSS | Ground | Reference return path for all digital and I/O signals |
| 5 / IO0 | Serial data I/O 0 | Bi-directional data line; functions as SI in single I/O mode, D0 in quad mode |
| 6 / IO1 | Serial data I/O 1 | Bi-directional data line; functions as SO in single I/O mode, D1 in quad mode |
| 7 / SCLK | Serial clock input | Master-generated clock driving all command, address, and data transfers |
| 8 / VCC | Power supply | Primary 3.0 V supply rail; decoupling required within 10 mm of pin |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI with 4-byte addressing | Enables direct access to full 128 Mbit address space without bank switching |
| Erase suspend/resume | Allows interruption of bulk erase to service time-critical reads, then resumes without data loss |
| Individual sector protection | Permits locking/unlocking of any 4-KB sector via status register bits, enabling secure firmware partitioning |
| Program/Erase suspend | Halts active program or erase operation to execute a read command, improving system responsiveness |
| Security register lock | Prevents unauthorized modification of configuration registers including protection settings and volatile/non-volatile bits |

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 |
|---|---|---|---|
| Cypress S25FL128SAGMFM001 | Same die, identical pinout and command set; differs only in marking and date code format | No functional difference; qualifies as form-fit-function replacement | Select when sourcing from legacy Cypress inventory or for cross-qualified BOMs |
| Winbond W25Q128JVSIM | 128 Mbit, 3.3 V, but uses different status register layout and lacks erase suspend/resume | Not suitable where interruptible erase is required for real-time systems | Choose only if quad SPI timing and sector protection meet design needs and suspend features are unused |
Compared with S25FL128LAGMFM003, the Cypress alternative provides seamless drop-in compatibility, while the Winbond part trades suspend functionality for broader distributor availability-making it viable only in non-real-time firmware storage roles.

FAQ
Is S25FL128LAGMFM003 compatible with standard SPI controllers?
Yes, it supports standard SPI mode (single I/O) as well as dual and quad I/O modes. All command sets comply with JEDEC JESD216B, and initialization uses standard SPI opcodes before enabling enhanced modes. No proprietary controller is required.
What is the minimum erase block size supported?
The smallest erasable unit is a 4-KB sector. The device supports uniform sector erase, 64-KB block erase, and chip erase. Sector-level granularity enables fine-grained firmware updates without disturbing adjacent code or configuration data.
Does this part support execute-in-place (XIP) operation?
Yes, S25FL128LAGMFM003 supports true XIP mode via quad SPI interface. The memory array is directly mapped into processor address space using memory-mapped I/O, enabling CPU instruction fetch without copying to RAM.
How is hardware write protection implemented?
Hardware write protection is controlled by the /WP pin (Pin 3). When held low, it prevents all program and erase operations regardless of status register settings. This complements software-based sector protection for defense-in-depth firmware security.
