GD25D10CEIGR

GD25D10CEIGR is a 1‑Mbit serial flash memory from GigaDevice (GD25D10C), packaged in an 8‑pin device (EIGR variant). It stores code and data with an SPI interface, suitable for firmware storage, bootloaders, or small data logging.
Key points:
- Density and organisation: 1 Mbit (128 KB), accessed via 3-byte addressing for reads/writes.
- Interface: SPI-compatible, with standard read, fast read, write enable/disable, and erase commands.
- Erase/Program: Page program (commonly 256 bytes), sector/block/chip erase options.
- Voltage and temp: typically 2.7–3.6 V operation; industrial temperature range (-40°C to +85°C).
- Package: 8‑pin small outline package (SOP) in the EIGR variant.
Note: exact opcodes, timing, endurance, and voltage details are specified in the latest datasheet; verify the specifics for your design.

Equivalent parts (1 Mb SPI Serial Flash, 2.7–3.6V, 8-pin SOIC):
- Winbond: W25Q10BV / W25Q10D
- Macronix: MX25D10 / MX25L10
