GD25LQ80EE2GR

GD25LQ80EE2GR is a GigaDevice serial flash memory part. Here’s a concise intro:
- Density and purpose: 8 Mbit (1 MB) non-volatile flash memory for firmware and data storage.
- Interface: SPI-compatible, with support for Quad SPI (QPI) modes for higher throughput.
- Organization and access: 1,048,576 x 8 bits; 256-byte pages; standard Read, Fast Read, and Quad/SPI reads; Page Program (256 bytes), Sector (4 KB), Block (32 KB/64 KB), and Chip Erase.
- Features: Deep power-down, hardware reset, write protection options, status register with busy flag, and security features.
- Endurance and retention: typical program/erase endurance in the 10^4–10^5 cycle range with long data retention.
- Voltage and package: Designed for low-voltage operation (commonly 2.7–3.6 V); available in RoHS-compliant 8-pin packages.
- Applications: Boot memory, firmware storage for microcontrollers, and other embedded storage needs requiring compact, fast non-volatile memory.
Note: exact timings, voltages, and command set should be confirmed from the official GD25LQ80EE2GR datasheet and JEDEC standard documentation.

Here are the key features of GD25LQ80EE2GR (8 Mbit serial flash):
