The GD25Q128ESIGR is a 128Mbit (16MB) SPI NOR Flash introduced by GigaDevice, featuring an SOP-8 package. It supports standard/dual/quad SPI, emphasizing high speed, low power consumption, and high reliability, widely used in embedded systems, consumer electronics, and industrial control.Capacity: 128Mbit (16MB), 16M×8-bit. Interface: Standard SPI (133MHz), Dual SPI (266Mbit/s), Quad SPI/QPI (532Mbit/s). Voltage: 2.7V–3.6V (Industrial Grade). Temperature: -40°C to +85°C. Read/Write: Page (256B) Program 500μs; 4KB Sector Erase 60ms; Full Chip Erase 200ms. Reliability: Endurance ≥100K cycles; Data Retention 20 years. Power Consumption: Standby 3μA; Deep Power-Down <1μA. Package: SOP-8 (208mil), Surface Mount.

Key Features High-Speed Transfer: Supports 133MHz clock, quad QPI mode throughput up to 532Mbit/s, read access time as low as 7ns. Flexible Memory Architecture: Uniform sectors (4KB), blocks (32KB/64KB), supports page program, sector/block/chip erase. Security Protection: Hardware/software write protection, OTP (One-Time Programmable) area, 64-bit unique ID to prevent data tampering. Low-Power Design: Suitable for battery-powered devices, deep power-down mode current <1μA. Compatible Replacement: Pin-compatible with mainstream SPI Flash, direct replacement for W25Q128JV, etc., simplifying upgrades.
