Infineon Technologies S25FL128LAGNFV010

Overview

S25FL128LAGNFV010 from Infineon is a 128-Mbit serial NOR flash memory with quad SPI interface, 3.0–3.6 V supply voltage, 100 MHz clock frequency, and 133 MHz equivalent data rate in QPI mode. It operates across industrial temperature range (−40°C to +85°C) and supports uniform 4-KB sectors for embedded firmware storage in microcontroller-based systems.

For engineers reviewing the S25FL128LAGNFV010 datasheet, S25FL128LAGNFV010 pinout, S25FL128LAGNFV010 application, or S25FL128LAGNFV010 equivalent, key selection criteria include sector erase granularity, XIP capability, write protection scheme, and JEDEC JESD216-compliant SFDP register support.

Technical Context

This device implements a standard Serial Peripheral Interface (SPI) with extended Quad I/O (QPI) mode for higher throughput. It features a 256-byte page programming buffer, configurable write protection via status registers and hardware WP# pin, and supports both volatile and non-volatile configuration lock bits.

The memory array is organized as 256 Kbytes × 64 bits, with erase operations supported at 4-KB sector, 64-KB block, and full-chip levels. Boot latency is minimized through fast read modes including continuous read with wrap-around and dual/quad output.

FAQ

Is S25FL128LAGNFV010 compatible with standard SPI controllers?

Yes, it supports legacy SPI mode (single I/O) at up to 80 MHz, in addition to dual and quad I/O modes. Standard SPI commands such as Read Status Register, Page Program, and Sector Erase are fully implemented per JEDEC JESD25 specification.

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

Yes, it supports XIP via continuous read modes with wrap-around addressing and low-latency fast read instructions. The device delivers deterministic access timing critical for direct code execution from flash without local RAM caching.

What write protection mechanisms are available?

It offers three layers: hardware WP# pin for global protection, software status register bits (SRWD, BP0–BP3) for sector/block locking, and volatile/non-volatile configuration lock bits to prevent accidental register changes during power transitions.

How is sector erase reliability verified?

Each 4-KB sector undergoes 100,000 program/erase cycles during qualification testing per AEC-Q100 stress conditions. Post-erase verification confirms all bits read as 0xFF before release, and data retention is validated at +85°C for 20 years.
