GD25Q80CWIGR

GD25Q80CWIGR is an 8-Mbit serial NOR flash memory from GigaDevice (GD25Q80C family). It provides non-volatile storage for microcontrollers and embedded systems.
Key points:
- Capacity and organization: 8 Mbit (1 Mbyte), organized for efficient read/write; 256-byte pages; sectors/blocks erase (typical sector sizes and a full-chip erase option).
- Interface: SPI-compatible, with options for higher throughput via dual/quad IO modes in supported configurations.
- Speed and addressing: designed for fast read operations; uses 3-byte addressing (with 4-byte addressing available in extended modes as needed).
- Power and reliability: operates from 2.7–3.6 V; features write enable/disable, status register, and protection mechanisms; power-down and deep power-down modes for low power.
- Package and availability: 8-pin package; RoHS-compliant; variant codes (like IGR) indicate packaging/temperature/grade specifics.
- Applications: boot flash, firmware/code storage, data logging, and other embedded storage needs.
Note: For exact electrical specs, timing, protocol modes, and pinout, consult the GD25Q80CWIGR datasheet.

Key features of GD25Q80CWIGR (8Mbit serial flash):
