AW95124FOR: A 24-bit I2C GPIO Expansion Chip Enabling Thinner and Lighter Foldable Phones

In today's rapidly evolving technological landscape, foldable phones stand out as one of the most groundbreaking innovations in the smartphone industry. Their blend of cutting-edge technology and stylish design has attracted significant investment from major industry players. Brands like vivo and Samsung have launched their own foldable phone masterpieces, showcasing the immense potential and vast growth prospects of this niche market. The innovative design concept of foldable phones not only reshapes the phone's appearance but also offers an unprecedentedly wide screen view and possibilities for innovative applications, quickly establishing them as a new favorite in the smartphone market. However, in the pursuit of the ultimate user experience, achieving thinner and lighter designs remains a critical challenge for the development of foldable phones.

To address this industry pain point, AW (All Winner) Electronics has launched its groundbreaking 24-bit I2C GPIO expansion chip, the AW95124FOR, injecting powerful impetus into the drive for thinner and lighter foldable phones. This chip significantly reduces the number of cross-board traces between the mainboard and sub-board of foldable phones, effectively reducing the overall thickness and ultimately enabling a thinner and lighter body design.

The core functionality of the AW95124FOR lies in its 24-bit I2C GPIO expansion capability and support for bidirectional level shifting between 1.08V and 3.6V. This feature allows the chip to efficiently save main control I/O resources, greatly simplifying system layout and wiring complexity, and effectively reducing system costs. Its applications extend beyond the mobile phone arena, encompassing diverse scenarios such as speakers and industrial internet of things (IoT), demonstrating its exceptional versatility and adaptability.

Detailed Product Features:

The AW95124FOR boasts several key features, making it an ideal choice for a thinner and lighter foldable phone solution:

• 24-bit GPIO Expansion: The AW95124FOR supports up to 24-bit GPIO expansion, crucial for applications requiring monitoring or control of numerous peripherals. These 24 GPIO bits can be flexibly divided into different groups, allocated to the main controller or co-processor for I/O expansion, significantly enhancing system scalability. In foldable phone applications, this feature can drastically reduce the number of cross-board traces, lower wiring complexity, and ultimately reduce system costs.

• 1.08V~3.6V Bidirectional Level Shifting: The AW95124FOR supports a wide range of 1.08V~3.6V level shifting, perfectly meeting the stringent requirements of advanced platforms like Qualcomm for 1.2V I/O levels. This bidirectional level shifting capability readily adapts to the conversion needs of different voltage domains. For example, the I2C side can operate at 1.2V, while the GPIO side can operate at 1.8V, effectively saving a level-shifting chip and further simplifying system design and reducing costs.

• Small Package, Thin Profile: The AW95124FOR uses a compact 2.6mm x 2.6mm package with a maximum thickness of only 0.6mm. This small package size is ideal for applications with stringent PCB space requirements, such as foldable phones, effectively helping manufacturers achieve thinner and lighter product designs and enhance product competitiveness.

• I2C-Only Reset Support: The AW95124FOR supports resetting the I2C interface independently. During the reset process, the GPIO side's state remains unaffected, significantly improving the reliability of the I2C module and the robustness of the entire system, enhancing system stability and anti-interference capabilities.

Summary of Product Advantages:

The core advantages of the AW95124FOR lie in its efficient GPIO expansion capability, wide-range level shifting support, compact package size, and reliable I2C reset mechanism. These advantages combine to make it an indispensable component in the drive for thinner and lighter foldable phones. Specifically, the main advantages of the AW95124FOR are:

• High Number of GPIO Expansion Lines: Up to 24-bit GPIO expansion lines provide ample expansion space for the system, meeting various complex interface requirements.

• Bidirectional Level Shifting: Supports 1.08V~3.6V bidirectional level shifting, effectively simplifying system design and reducing costs.

• Small Size and Thin Package: The compact package size and thin profile save valuable PCB space, providing strong support for thinner and lighter phone designs.

• Enhanced System Reliability: Support for I2C-only reset enhances I2C module reliability and ensures stable system operation.
