Description
GD25LD20CEIGR is a GigaDevice 2‑Mbit serial SPI flash memory. It stores firmware and data in embedded systems and comes in an 8‑pin RoHS package. Key points:
- Density: 2 Mbit (256 KB)
- Interface: Standard SPI (with options for fast read)
- Features: Read/fast read, write enable/disable, page program, sector/block/chip erase, and status register access
- Power: typically operates from a low supply (e.g., around 2.7–3.6 V; variants exist for different temp ranges)
- Packaging: 8‑pin package (suffix indicates RoHS/commercial/industrial options)
- Common uses: boot code storage, configuration data, firmware updates, data logging
The “CEIGR” suffix mainly encodes the package, temperature range, and RoHS/industrial options. For exact electrical specs, timing, erase sizes, endurance, and pinout details, consult the GD25LD20CEIGR datasheet from GigaDevice.
