GD25Q127CFIGR

The GD25Q127CFIGR is GigaDevice’s 128-Mbit serial flash memory (8-pin package) with an SPI-compatible interface, designed for firmware storage and bootCode in embedded systems. Key points:
- Capacity and organization: 128 Mbit (16 MBytes); page size 256 bytes; sectors (4 KB) and blocks (64 KB) for erase.
- Interface and speed: SPI with Fast Read, plus dual/quad I/O modes for higher throughput; typical operation up to 104 MHz (QPI/ Quad modes enable higher data rates).
- Voltage and power: operates from 2.7–3.6 V; features Deep Power-Down and standby modes for low power.
- Commands and features: standard flash commands (Read, Fast Read, Page Program, Sector/Block/Chip Erase, Write Enable, Read/Write Status), hardware protection (WP, block protect).
- Package and temp: F = 8-pin SOP package; I = industrial temperature range; GR = RoHS compliant.
Common uses: firmware storage, boot devices, and code/data storage in microcontroller-based systems. For exact electrical specs and command set, consult the latest datasheet.
