Présentation

Description

GD25LQ64CSIGR is a 64‑Mbit serial flash memory from GigaDevice. It uses SPI (standard, Dual, and Quad I/O modes) and comes in an 8‑pin package (IGR suffix indicates RoHS lead‑free packaging). Operating voltage is typically 2.7–3.6 V. It supports high‑speed read and Quad I/O read, as well as page program writes and erase commands (sector/block/chip erase). It includes a Write Enable Latch, status register, and a deep power‑down mode for low power. Endurance is typical of serial flash (program/erase cycles), making it suitable for firmware/code storage, boot ROM, and data storage in MCUs, microprocessors, and SoCs. For exact timing, command set, pinout, and electrical characteristics, refer to the GD25LQ64CSIGR datasheet.

Pinout

- Pin count: 8 pins (SOP-8/SOIC-8).
- Function: 64 Mbit serial NOR flash memory with SPI interface (non-volatile storage for code/data). Uses standard SPI read/write/erase commands.
- Typical pinout (orientation may vary):
1 = CS#,
2 = DO (MISO),
3 = WP#,
4 = GND,
5 = DI (MOSI),
6 = CLK,
7 = VCC,
8 = HOLD#.
Note: WP# and HOLD# can be tied high if not used.

Manufacturer

- Manufacturer: GigaDevice Semiconductor Inc. (GigaDevice)
- What kind of company: A fabless semiconductor company based in Beijing, China, specializing in flash memory and microcontroller products; designs memory ICs (e.g., NOR serial flash) and outsources fabrication to foundries.

Application

Applications of GD25LQ64CSIGR (64‑Mbit serial flash):
- External program/firmware memory for MCUs/MPUs; boot code and firmware updates
- Data storage and logging in IoT, wearables, and industrial equipment
- Parameter/config storage in automotive and industrial controllers
- Firmware images for consumer electronics and networking gear
- Field upgrades and secure firmware deployment via SPI/QSPI interfaces
- Cache or scratchpad memory in MCUs requiring fast random reads
These uses leverage its QPI/dual/quad SPI interfaces for high‑performance non-volatile storage.

Package

GD25LQ64CSIGR uses an 8-pin SOIC package (SOP-8).
