Product details
Overview
S25FS128SAGBHI300 from Infineon is a 128 Mbit (16 MB) serial NOR flash memory with SPI Multi-I/O interface, 1.8 V supply, industrial temperature grade (–40°C to +85°C), and WSON 6 × 8 mm package. It supports Quad I/O, DDR Quad I/O read up to 80 MBps, 256/512-byte page programming, hardware ECC, and hybrid/uniform sector erase options. Used for firmware storage in embedded controllers requiring XIP-capable, high-reliability nonvolatile memory.
For engineers reviewing the S25FS128SAGBHI300 datasheet, S25FS128SAGBHI300 pinout, S25FS128SAGBHI300 application, or S25FS128SAGBHI300 equivalent, key selection criteria include SPI-MIO timing compliance, 1.8 V operation margin, OTP security configuration, hybrid sector layout compatibility, and AEC-Q100 grade alignment for automotive ECUs.
Technical Context
This device implements Infineon's Eclipse architecture with 65-nm MIRRORBIT™ technology, enabling true random access via burst wrap and continuous XIP modes. It supports both standard SPI (modes 0/3) and extended addressing (24-/32-bit), with SFDP v1.6 and CFI for auto-configuration.
The command set includes program/erase suspend-resume, advanced sector protection (ASP) with password-controlled read access, and dedicated OTP array (1024 bytes). Erase endurance is rated at ≥100,000 cycles with 20-year data retention under industrial conditions.

FAQ
What is the maximum clock frequency for DDR Quad I/O read operations?
The S25FS128SAGBHI300 supports DDR Quad I/O read at up to 80 MHz, delivering 80 MBps effective throughput. This is specified under VCC = 1.8 V and TA = –40°C to +85°C, with setup/hold timing validated per datasheet Section 6.5. No external DLL or phase alignment circuitry is required.
Does this device support 32-bit addressing for >16 MB address space?
Yes - the device implements extended addressing with configurable 24-bit or 32-bit address modes. When 32-bit addressing is enabled via Configuration Register bit CR3[0], the full 128 Mbit array is accessible using four-byte addresses, enabling seamless migration to higher-density variants.
How is the OTP array protected from accidental overwrite?
The 1024-byte OTP array is write-locked after initial programming; further writes require OTP-specific unlock sequences and are permanently disabled upon successful programming. Protection is enforced by on-die logic - no external voltage or timing conditions are needed to maintain OTP integrity.
Can the WP# pin be used as a general-purpose I/O during normal operation?
No - WP# functions exclusively as hardware write protect in standard SPI mode. In Quad or DDR modes, it becomes IO2 and is fully bidirectional, but its protection function is disabled. The pin cannot serve dual roles simultaneously; configuration is mode-dependent and fixed by command protocol.
