Product details
Overview
S25FL256LAGNFV010 from Infineon is a 256-Mbit (32-MB) serial NOR flash memory with Quad SPI interface, 133 MHz clock frequency, and 1.8 V core supply voltage. It supports XIP (execute-in-place), dual/quad I/O protocols, and sector-erase architecture for embedded code storage in microcontroller-based systems.
For engineers reviewing the S25FL256LAGNFV010 datasheet, S25FL256LAGNFV010 pinout, S25FL256LAGNFV010 application, or S25FL256LAGNFV010 equivalent, key selection criteria include read latency, erase granularity, write protection scheme, and industrial temperature range compliance.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O mode, enabling up to 532 MB/s effective throughput. It features a 64-byte page programming buffer, uniform 4-KB sector erase capability, and hardware-controlled write protection via WP# pin and status register bits.
The memory array is organized as 512 pages per sector × 512 sectors, supporting both volatile and non-volatile configuration registers. Erase suspend/resume and deep power-down modes are supported for system-level power management in battery-sensitive applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY15B104QN-SXIT | 4-Mbit density, FRAM technology, unlimited endurance, 20 MHz max clock | Lower density, no XIP, suited for frequent small-data logging not code storage | Select only when byte-level write endurance and zero write latency outweigh capacity and speed needs |
| MX25L25645GZC-13G | Same 256-Mbit density, 133 MHz, but 3.3 V supply and no deep power-down mode | Requires separate LDO for 3.3 V rail; unsuitable for ultra-low-power battery operation | Prefer when existing 3.3 V system infrastructure eliminates need for additional voltage translation |
Compared with CY15B104QN-SXIT and MX25L25645GZC-13G, the S25FL256LAGNFV010 uniquely balances high-density code storage, industrial temperature resilience, and sub-10 µA deep power-down-making it optimal for resource-constrained, field-upgradable embedded systems.

FAQ
What is the maximum data transfer rate achievable with S25FL256LAGNFV010 in Quad SPI mode?
In Quad SPI read mode at 133 MHz clock frequency, the device achieves an effective throughput of 532 MB/s (133 MHz × 4 bits). This assumes continuous burst reads with no command/address overhead and proper PCB layout minimizing signal skew across IO0–IO3 lines. Real-world sustained rates depend on host controller capabilities and bus contention.
Does S25FL256LAGNFV010 support execute-in-place (XIP) operation?
Yes, the device supports XIP mode via Quad SPI interface, allowing the host MCU to directly fetch and execute instructions from flash without loading into RAM. XIP requires host QSPI controller compatibility with continuous read commands and proper cache coherency handling for modified data sections.
How is hardware write protection implemented on this part?
Hardware write protection uses the dedicated WP# pin, which when pulled low disables all program and erase operations. Additionally, software-controlled protection is available via status register bits (SRWD, BP0–BP3) to lock individual 4 KB sectors or the entire memory array, providing layered security against accidental or malicious writes.
Is S25FL256LAGNFV010 compliant with AEC-Q100 for automotive use?
No, S25FL256LAGNFV010 is rated for industrial temperature range (−40°C to +105°C) but is not AEC-Q100 qualified. For automotive applications requiring AEC-Q100 Grade 2 or 3 certification, Infineon offers the pin-compatible S25FL256SAGMFV010 variant, which undergoes additional stress testing and lot-level qualification.
