Product details
Overview
S25FS128SAGMFV100 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 × 5 mm package. It supports Quad I/O, DDR Quad I/O read up to 80 MBps, 256-byte/512-byte page programming, hardware ECC, and hybrid/uniform sector erase options.
For engineers reviewing the S25FS128SAGMFV100 datasheet, S25FS128SAGMFV100 pinout, S25FS128SAGMFV100 application, or S25FS128SAGMFV100 equivalent, key selection criteria include SPI-MIO timing compliance, SFDP/CFI configuration support, OTP array usage, AEC-Q100 grade compatibility, and hybrid sector layout for boot code partitioning.
Technical Context
This device implements Infineon's 65-nm MIRRORBIT™ Eclipse architecture with dual-plane read capability and configurable address width (24-/32-bit). Its SPI-MIO interface supports standard SPI modes 0/3, QPI mode, and DDR command execution with dedicated IO0–IO3 bidirectional pins.
The embedded algorithm engine enables program/erase suspend-resume, automatic single-bit ECC correction, and sector protection via status register bits or advanced password-controlled ASP. Erase endurance is rated at ≥100,000 cycles with 20-year data retention under industrial conditions.

FAQ
What is the maximum clock frequency supported in DDR Quad I/O mode?
The S25FS128SAGMFV100 supports DDR Quad I/O read at up to 80 MHz clock frequency, delivering 80 MBps effective bandwidth. This is specified in the AC characteristics section of the datasheet (Rev. *O, Table 6.5), and requires proper PCB layout with matched trace lengths and controlled impedance for all four I/O lines.
Does this device support 32-bit addressing for >16 MB memory maps?
Yes, the device supports both 24-bit and 32-bit addressing modes via configuration register settings. When 32-bit addressing is enabled, the full 128 Mbit address space is accessible using extended address bytes, enabling compatibility with larger firmware images and future-proof memory mapping.
How is the OTP array accessed and protected?
The 1024-byte OTP array is accessed via dedicated JEDEC-standard One-Time Program commands (0x4B, 0x42). Once programmed, bits cannot be reset. Protection is enforced by status register lock bits and requires Write Enable before programming; unprogrammed regions remain readable but write-protected after first use.
Can the hybrid sector layout be configured at runtime?
No, the physical hybrid sector layout (eight 4-KB + one 32-KB sectors) is fixed by silicon design and cannot be altered. However, logical sector mapping can be managed via software using the device's uniform sector option commands, allowing emulation of uniform 64-KB blocks for legacy compatibility.
