GD25VQ80CSIGR

A: The GD25VQ80CSIGR is designed for high performance and low power consumption. The table below summarises its core specifications, drawn directly from manufacturer data and multiple distributor sources: Specification Value Memory Density 8 Mbit (1 Mbyte) Memory Organization 1M × 8 bits (1,048,576 × 8) Memory Technology NOR Flash Memory Interface SPI, Dual I/O, Quad I/O Max Clock Frequency 104 MHz Supply Voltage (VCC) 2.3 V to 3.6 V (2.3V min, 3.6V max) Write Cycle Time – Word 50 µs (max) Write Cycle Time – Page 3 ms (max) Active Read Current Not specified (refer to datasheet) Standby Current (Typical) 1 µA Deep Power‑Down Current 1 µA Erase Granularity Uniform 4KB sectors, 32KB/64KB blocks Endurance 100,000 program/erase cycles (minimum) Data Retention 20 years (minimum) Operating Temperature (Industrial) –40°C to +85°C Package Type 8‑pin SOP (SOIC‑8, 5.30 mm width) Moisture Sensitivity Level (MSL) 3 (168 hours) RoHS Status ROHS3 Compliant Additional features include: Uniform Sector Architecture: Flexible erase options with 4KB sectors and 32KB/64KB blocks, optimising memory management for both code and data storage. Low Power Consumption: Typical standby and deep power‑down current of just 1 µA, making the device ideal for battery‑powered and energy‑harvesting applications. Quad SPI Support: Quad I/O mode allows four bits of data to be transferred per clock cycle, achieving an effective data rate equivalent to 416 MHz when operating at 104 MHz. Hardware and Software Write Protection: Configurable block protection via status register bits and write enable latch (WEL), ensuring data integrity in mission‑critical systems.

A: The device uses a standard 4‑wire Serial Peripheral Interface (SPI) bus for communication, operating in either SPI Mode 0 (CPOL=0, CPHA=0) or Mode 3 (CPOL=1, CPHA=1) for maximum compatibility with a wide range of microcontrollers and SoCs. The interface consists of the following signals [6†L4]: Pin Signal Group Function /CS (Chip Select) Enables the device when driven low CLK (Serial Clock) Provides the clock signal for data transfer (up to 104 MHz) SI / IO0 Serial data input (I/O0 in Dual/Quad modes) SO / IO1 Serial data output (I/O1 in Dual/Quad modes) WP / IO2 Hardware write protect pin (I/O2 in Quad mode) HOLD / IO3 Pauses an ongoing serial communication without resetting the ongoing instruction (I/O3 in Quad mode) The device supports multiple flexible interface modes: Standard SPI (Single I/O) : Uses separate SI (data in) and SO (data out) pins for 1‑bit transfers. Dual SPI (Dual I/O) : The SI and SO pins become bidirectional I/O pins (IO0 and IO1) for 2‑bit per cycle transfers, effectively doubling the data rate. Quad SPI (Quad I/O) : All four I/O pins (IO0, IO1, IO2, IO3) are used for simultaneous data transfer, achieving 4‑bit per cycle throughput — equivalent to an effective data rate of 416 MHz when operating at 104 MHz. The Continuous Read Mode enables efficient memory access, allowing the host to execute code directly from the flash memory without copying it to RAM first (Execute‑In‑Place, XIP).

A: The GD25VQ80CSIGR is engineered for long‑term reliability in demanding embedded applications. Key specifications include [8†L12-L15]: Reliability Parameter Specification Program/Erase Endurance 100,000 cycles per sector (minimum) Data Retention 20 years (minimum) Write Cycle Time – Word 50 µs (max) Write Cycle Time – Page 3 ms (max) Operating Temperature –40°C to +85°C (industrial grade) Standby Current 1 µA (typical) Deep Power‑Down Current 1 µA (typical) These reliability figures meet industry‑standard requirements for NOR Flash technology. The device also includes hardware and software write protection features, a write enable latch (WEL) , and configurable block protection via status register bits, ensuring data integrity in mission‑critical systems.

A: The GD25VQ80CSIGR is well‑suited for a wide range of embedded applications requiring reliable, low‑power code and data storage with a simple, low‑pin‑count interface. Typical applications include: Firmware and boot code storage – Bootloaders, BIOS, and application code in embedded systems, supporting IAP (In‑Application Programming) and OTA (Over‑The‑Air) upgrades. Industrial control systems – PLCs, HMIs, data loggers, and factory automation equipment. Internet of Things (IoT) devices – Wi‑Fi modules, Bluetooth modules, smart home controllers, and sensor nodes. Consumer electronics – Smart TVs, set‑top boxes, digital cameras, gaming consoles, and smart speakers. Medical devices – Diagnostic equipment and patient monitors. Automotive electronics – Infotainment systems, navigation units, and OBD diagnostic devices (standard industrial grade). ⚠️ Important Lifecycle Information: The product lifecycle status for the GD25VQ80CSIGR is Active (in mass production). Multiple distributor sources confirm the Part Status as Active [1†L4-L9][6†L11][7†L8][8†L12]. DigiKey lists the component status as 在售 (In Stock/On Sale) [9†L7]. The manufacturer‘s standard package quantity is 2,000 units per reel (Tape & Reel packaging) [4†L6][5†L12], and the product is ROHS3 Compliant [6†L13][8†L6]. For new designs requiring an 8‑Mbit Serial NOR Flash with Quad I/O capabilities, industrial temperature range, and low power consumption, the GD25VQ80CSIGR remains an active, suitable choice. However, engineers are advised to verify current availability, pricing, and lead times directly with an authorised GigaDevice distributor (such as DigiKey, Mouser, or LCSC) before committing the part to a new high‑volume design.
