Infineon Technologies S25FL128LAGMFV010

Overview

S25FL128LAGMFV010 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 QSPI mode. It supports XIP (execute-in-place), sector erase, and deep power-down mode for low-power embedded applications.

For engineers reviewing the S25FL128LAGMFV010 datasheet, S25FL128LAGMFV010 pinout, S25FL128LAGMFV010 application, or S25FL128LAGMFV010 equivalent, key selection criteria include quad I/O timing compliance, sector protection granularity, write endurance (100K cycles), and industrial temperature range (-40°C to +85°C) support.

Technical Context

This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O (QPI) command set compliant with JEDEC JESD216B. It uses stacked-die technology to achieve 128 Mbit density in an 8-pin SOIC package with uniform 4-KB sectors and 64-KB blocks.

Internal architecture includes a 256-byte page buffer, hardware write protection via WP# pin and status register bits, and configurable reset enable/disable. The device supports both volatile and non-volatile configuration registers for latency tuning and read mode selection.

FAQ

Is S25FL128LAGMFV010 compatible with standard SPI controllers?

Yes, it supports standard single-I/O SPI mode (mode 0 and mode 3) alongside dual and quad I/O modes. All commands are backward-compatible with legacy SPI hosts, though quad mode requires controller support for extended instruction sets defined in JEDEC JESD216B.

What is the minimum pulse width requirement for the WP# pin to activate hardware protection?

The WP# pin must be held low for at least 20 ns before CS# goes low to enable hardware write protection. This timing ensures reliable latching of protection state prior to command execution, as specified in the device's AC characteristics table.

Does this part support unique ID or secure boot features?

No, S25FL128LAGMFV010 does not include a factory-programmed unique ID or cryptographic acceleration. It supports basic security via software-configurable block protection and hardware WP#, but lacks dedicated secure boot or AES encryption engines found in Infineon's OPTIGA™ or SLB96xx families.

Can the device operate at 2.7 V supply voltage?

No, the absolute minimum VCC is 2.7 V only for standby mode per datasheet Absolute Maximum Ratings; functional operation requires 3.0 V minimum. Operating below 3.0 V may cause command timeout, read corruption, or failed erase verification.
