Tổng quan
Description
GD25LQ40EEIGR is a GigaDevice 4-Mbit serial (SPI) flash memory. It’s used to store code or data in embedded systems.
Key points:
- Capacity: 4 Mbit (512 KB) non-volatile flash.
- Interface: Serial SPI (classic mode; some variants also support Quad I/O for higher throughput).
- Addressing: 3-byte addressing (typical for ≤ 8 Mbit devices).
- Pages/sectors: 256-byte pages; erase blocks of 4K/32K/64K; chip erase supported.
- Voltage: operates on a single supply around 2.7–3.6 V.
- Features: Write Enable Latch, status/config registers, block protection, deep power-down, wake/auto‑sleep modes.
- Package/grade: 8-pin package; suffix indicates RoHS-compliant packaging and temperature grade (industrial/extended), as per datasheet.
Applications: boot memory, configuration storage, data logging in microcontroller systems. For exact electrical characteristics, timing, and package details, consult the GD25LQ40E datasheet corresponding to the -GR variant.
