FAQ

Is S25FL256LAGBHV023 compatible with standard SPI controllers?

Yes, it supports standard SPI mode (single I/O) at up to 80 MHz, in addition to dual and quad I/O modes. Command sets follow JEDEC JESD251, ensuring interoperability with common MCU SPI peripherals without custom drivers.

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

Yes, its 8 ns read latency and continuous read mode enable reliable XIP execution directly from flash memory on Cortex-M and other ARM-based MCUs, eliminating need for external RAM loading during boot.

What is the data retention specification?

Data retention is guaranteed for 20 years at +85°C ambient temperature and 10 years at +105°C, based on accelerated life testing per JEDEC standards, making it suitable for unattended industrial deployments.

How is write protection implemented?

It combines hardware write protection via the WP# pin (active-low, tied to VIO or ground) and software-controlled block protection using BP0–BP2 bits in the status register, allowing selective lockdown of top/bottom sectors.
