Product details
Overview
S25FL256LAGNFI010 from Infineon is a 256-Mbit serial NOR flash memory with Quad SPI interface, 1.8 V supply voltage, 133 MHz clock frequency, and uniform 4-KB sector erase capability. It serves as non-volatile program/data storage in microcontroller-based embedded systems requiring fast read access and reliable code execution.
For engineers reviewing the S25FL256LAGNFI010 datasheet, S25FL256LAGNFI010 pinout, S25FL256LAGNFI010 application, or S25FL256LAGNFI010 equivalent, key selection criteria include Quad SPI timing compliance, 1.8 V VCC tolerance, sector protection granularity, 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 mode supporting single/dual/quad read commands. It uses a floating-gate NAND architecture with on-chip ECC for bit error correction during read operations.
Command set complies with JEDEC JESD216B for SFDP (Serial Flash Discoverable Parameters), enabling automatic configuration by host boot ROM. Write protection includes hardware WP# pin control and software block lock bits per 4-KB sector.
Key Specifications

|---|---|---|---|
| S25FL256SAGNFI000 | Same density and package but lacks on-die ECC and SFDP support; uses legacy command set | Not suitable for safety-critical or auto-configuring boot systems requiring ECC or dynamic timing setup | Select only if cost sensitivity outweighs reliability and configurability needs |
| MX25L25645GMI-10G | 256 Mbit, 3 V supply, no on-die ECC, supports DTR mode up to 80 MHz dual-transfer rate | Requires 3 V rail; lacks ECC and SFDP; better suited for legacy 3 V designs with lower speed demands | Choose only for backward compatibility in existing 3 V platforms where voltage scaling is not feasible |

FAQ
Is S25FL256LAGNFI010 compatible with standard SPI controllers?
Yes-it supports standard SPI modes (0,3) for single I/O operation and extends to dual/quad I/O via JEDEC-compliant command sequences. Host firmware must issue appropriate instruction opcodes (e.g., 0x6B for quad read) and configure GPIOs accordingly. No special controller hardware is required beyond configurable SPI peripheral support.
Does this part support execute-in-place (XIP) operation?
Yes-its Quad SPI interface and fast random read access (≤8 ns initial latency, ≤100 ns typical) enable direct code execution from flash memory by compatible MCUs. XIP functionality depends on host processor support for memory-mapped SPI flash and proper cache coherency handling.
What is the purpose of the HOLD# pin?
HOLD# pauses ongoing serial communication without resetting internal state or losing address context. When asserted low during a read or write sequence, the device halts data transfer and releases the bus, allowing other peripherals to use shared SPI lines while preserving transaction position.
How does on-die ECC function during normal operation?
On-die ECC automatically detects and corrects single-bit errors during every read operation without CPU involvement. It uses dedicated hardware logic and spare bits stored per 512-byte sector. No additional latency is added, and corrected data is delivered transparently to the host interface.
