S25FL512SAGBHIC13

S25FL512SAGBHIC13 is a 512‑Mbit serial NOR flash memory (SPI) from the S25FL512S family (Cypress/Spansion). It is used to store firmware and other non‑volatile data in embedded systems, often as boot or update storage.
Key points:
- Capacity and interface: 64 MB of storage accessible over a serial SPI interface; supports standard SPI and higher‑speed I/O modes (Dual/Quad I/O, and QPI in applicable variants). Uses 4‑byte addressing for addresses beyond 16 MB.
- Memory organization: typically organized into sectors/blocks (e.g., 4 KB sectors; larger blocks); supports page programming (commonly 256 bytes) and block/sector erase.
- Features: fast read, security and protection features (block/region protection, status/config registers), and XIP (execute in place) capabilities in suitable systems.
- Electrical/physical: nominal Vcc ≈ 2.7–3.6 V (variant/grade dependent); packaging and temperature range vary by suffix (HIC13 identifies the exact variant).
- Applications: code storage, boot ROM, firmware updates.
Note: The SAGBHIC13 suffix specifies the exact variant, voltage/temperature range, and packaging; consult the datasheet for exact specs.

Equivalent 512-Mbit SPI NOR flash parts (pin-compatible, 3.0V class) include:
- Macronix MX25L51245G
- Winbond W25Q512JV
- Gigadevice GD25Q512B
- ISSI IS25LP512D
Note: check exact voltage, timing, package, and die revisions for direct drop-in compatibility.
