GD25Q127CFIG is a state-of-the-art Quad-SPI memory device, built on a common Flash technology platform. With its advanced design, it comes with a wide range of features and advantages that make it well-suited for various applications.

The GD25Q127CFIG belongs to the family of embedded non-volatile memory products. It features a 1 Gbit (128Mb) capacity and two independent true Serial Peripheral Interface Bus (SPI bus) with dual-SPI and quad-SPI support. It is designed for use in applications that require data storage for lower power platforms and requires single-bit I/O operations to reduce transition time and improve system performance.

The device consists of two quad-SPI memory banks which can be used independently or configured in a combined dual-SPI mode. Each memory bank has a common command interface, address bus and data bus. It operates at 45MHz clock when using dual-SPI mode, with a maximum of 10MHz in Quad-SPI mode.

The device can operate in either master or slave mode, and supports a wide range of serial bus protocols, including QSPI, SPI, and Single Wire Peripheral (S-Wire) protocols. The device is also compatible with both synchronous or asynchronous data transfer modes. It supports four SPI read modes, including single, dual, quad and octo, as well as one write mode. It has a wide operating temperature range of -40°C to +85°C.

The GD25Q127CFIG also supports an extensive set of reliable data protection and security features. It supports a write enable (WE) pin for simple enable/disable control and has both address and data protection via the security registers. It has an internal programmable one-time programmable (OTP) register which can contain up to 8KB of custom data. It also has an erase protection to ensure that the data stored in the device is not accidentally erased. Additionally, it supports a secure counter which is used to store a unique ID and can be used to store system entropy.

In terms of memory layout, the device is organized into 16 blocks of 32 KB with a total storage capacity of 16MB. Each of the 16 blocks can be individually erased, programmed and read. The device also supports secondary memories such as 4KB EEPROM and 4KB protection registers.

Overall, the GD25Q127CFIG is a high-performance memory device designed for a wide range of applications. It can be used for data storage in a wide range of systems such as embedded systems, portable devices, home automation, wearable devices, and so on. Thanks to its advanced features and robust data protection capabilities, it is a perfect choice for low-power and performance-critical applications.
