S25FL512SAGBHIC10

S25FL512SAGBHIC10 is a high-density serial NOR flash memory from the S25FL/SPI family (Spansion/Cypress) used to store firmware and data in embedded systems. It provides a Quad SPI interface and supports single/dual/quad IO, plus 4‑byte addressing to reach 64 MBytes.
Key points:
- Capacity/interface: 512 Mbit (64 MB); Quad SPI; 2.7–3.6 V supply; supports 4‑byte addressing.
- Memory organization: 256‑byte pages; sectors (typically 4 KB); blocks (e.g., 64 KB/256 KB); supports sector/block/Chip Erase and Page Program.
- Features: fast/continuous read, Deep Power-Down, protection and security features, standard and Quad I/O operation; requires enabling Quad mode via command.
- Uses: firmware/code storage and updates for MCUs/SoCs, data logging, boot flash.
- Package/grade: suffix indicates package type and temperature grade (industrial variants common).
For exact timings, command set, and package options, consult the datasheet.
