Infineon Technologies S25FL128LAGMFM013

Overview

S25FL128LAGMFM013 from Infineon is a 128-Mbit serial NOR flash memory with quad SPI interface, 3V supply voltage, and 133 MHz read clock frequency. It supports XIP (execute-in-place), dual/quad I/O protocols, and offers 100K program/erase cycles with 20-year data retention.

For engineers reviewing the S25FL128LAGMFM013 datasheet, S25FL128LAGMFM013 pinout, S25FL128LAGMFM013 application, or S25FL128LAGMFM013 equivalent, key selection criteria include quad SPI timing compliance, sector protection granularity, erase suspend/resume capability, and industrial temperature range operation (-40°C to +85°C).

Technical Context

This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O (QPI) mode for high-throughput code execution. It features uniform 4-KB sectors and 64-KB blocks, configurable write protection via status register bits and hardware WP# pin, and supports both fast read (up to 133 MHz) and continuous read modes.

The memory architecture includes an internal address counter for sequential reads, programmable latency code for timing optimization, and a 256-byte page programming buffer. Erase operations are supported at sector, block, and chip levels with built-in erase suspend/resume functionality for real-time system responsiveness.

FAQ

What is the maximum clock frequency supported in Quad SPI mode?

The S25FL128LAGMFM013 supports up to 133 MHz in Quad SPI (QPI) mode, delivering 532 MB/s effective throughput. This frequency is validated under industrial temperature conditions and requires proper PCB layout with controlled impedance traces and matched signal lengths for all four I/O lines.

Does this device support execute-in-place (XIP) operation?

Yes, the device supports true XIP operation with low-latency random access and continuous read modes. Its 133 MHz read clock and internal address counter allow direct CPU instruction fetch from flash without copying to RAM, reducing boot time and memory footprint in resource-constrained MCUs.

How is write protection implemented on this flash memory?

Write protection uses both hardware and software methods: the WP# pin provides physical sector locking, while status register bits (SRWD, BP0–BP3) enable software-configurable protection for individual 4-KB sectors or groups. Protection remains active after power cycle unless explicitly cleared via unlock sequence.

What package type is used for S25FL128LAGMFM013?

The S25FL128LAGMFM013 uses a 16-pin SOIC package with 300 mil width and 150 mil body, compliant with JEDEC MS-012AC. Pin pitch is 1.27 mm, and the package is RoHS-compliant with moisture sensitivity level 3 (MSL3), requiring bake before reflow if exposed beyond floor life.
