Product details
Overview
S25FL127SABMFB100 from Infineon is a 128 Mb (16 MB) serial NOR flash memory with SPI Multi-I/O interface, 3.0 V core supply, and 65-nm MIRRORBIT™ Eclipse architecture. It supports Quad Read at up to 54 MBps, 256/512-byte page programming with hardware ECC, and hybrid/uniform sector erase options. Used in boot code storage for industrial microcontrollers requiring fast, reliable nonvolatile code execution.
For engineers reviewing the S25FL127SABMFB100 datasheet, S25FL127SABMFB100 pinout, S25FL127SABMFB100 application, or S25FL127SABMFB100 equivalent, key selection factors include Quad I/O read performance, OTP security array size, AEC-Q100 Grade 2 qualification, and SOIC-16 package compatibility with legacy FL-S designs.
Technical Context
This device implements SPI-MIO (Multi-I/O) with configurable clock polarity/phase (modes 0 and 3), supporting Normal/Fast/Dual/Quad Read commands and AutoBoot execution from preselected addresses. It uses CFI and JEDEC JESD216B SFDP for standardized configuration discovery.
Erase architecture offers two modes: hybrid (16 × 4-KB + remainder 64-KB sectors) and uniform (256-KB logical blocks). Programming includes Quad-input Page Programming (QPP) and automatic single-bit ECC correction, enabling robust operation in low-clock embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 128 Mb (16 MB) - sufficient for full firmware images and parameter tables in mid-tier MCUs |
| Read Speed (Quad) | 54 MBps at 108 MHz - enables sub-300 ms boot time for 16 MB image |
| Page Programming | 256- or 512-byte buffer with QPP - reduces host CPU overhead in resource-constrained systems |
| Erase Options | Hybrid (4 KB/64 KB) or uniform (256 KB) - balances fine-grained update flexibility vs. software compatibility |
| Data Retention | 20 years minimum - meets long-life requirements for industrial control and automotive ECUs |
| Endurance | 100,000 program-erase cycles per sector - supports frequent field firmware updates |
| OTP Array | 1024 bytes one-time programmable - stores cryptographic keys or calibration data irreversibly |
Pinout & Package
Package: 16-lead SOIC (300 mil), Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select | Active-low enable for SPI command decoding; supports daisy-chain or multi-device bus sharing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress S25FL128SAGMFI101 | Same die, identical pinout and timing; differs only in marking and test grade (Industrial vs. Industrial Plus temp range) | Rated for –40°C to +105°C; higher thermal margin for extended ambient environments | Select when operating above +85°C ambient or requiring extended temperature qualification |
| Winbond W25Q128JVSIM | 128 Mb, Quad SPI, but lacks AutoBoot, ASP, and SFDP v1.6 compliance; no hardware ECC | No OTP or advanced protection - suitable only for cost-sensitive, non-security applications | Choose only if security features and guaranteed boot behavior are not required |
Compared with S25FL127SABMFB100, the S25FL128SAGMFI101 offers identical functionality with extended temperature support, while the W25Q128JVSIM sacrifices security and boot automation for lower BOM cost - making it unsuitable for safety- or mission-critical deployments.

FAQ
Is S25FL127SABMFB100 pin-compatible with earlier S25FL-A or S25FL-K series devices?
Yes - it maintains identical SOIC-16 pinout and command set compatibility with S25FL-A, S25FL-K, and S25FL-P families. Signal mapping, voltage levels, and timing margins are preserved, enabling drop-in replacement in existing PCB layouts without redesign.
Does this part support Execute-in-Place (XIP) operation?
Yes - the device supports XIP via Quad SPI interface with AutoBoot functionality. When configured, it automatically executes a Quad Read command at power-up from a user-defined address, enabling direct code execution from flash without RAM loading.
What is the function of the HOLD# pin beyond pausing transactions?
HOLD# serves dual purpose: as a hardware transaction pause signal (active-low), and as IO3 in Quad SPI mode. In QPI mode, it becomes a bidirectional data line, enabling 4-bit parallel transfers - essential for achieving 54 MBps read bandwidth.
How is the 1024-byte OTP array accessed and protected?
The OTP array resides at fixed address 0x00000000 and is accessed via dedicated One-Time Program commands. Once programmed, bits cannot be reset. Protection is enforced by status register lock bits and requires Write Enable before any OTP write - preventing accidental overwrite during normal operation.
