Maxim Integrated MAX7328AWE I/O Expander

The MAX7328AWE is a versatile and robust I/O expander from Maxim Integrated, designed to enhance the interface options of microcontrollers and microprocessors in a wide range of applications. This powerful component allows for the expansion of I/O ports through a simple two-wire I²C-compatible serial interface, making it an ideal solution for systems with limited GPIOs.

Key Features

• Port Expander: Offers 8 push-pull or open-drain I/O ports that can be used for input, output, or as interrupt inputs.
• Serial Interface: Utilizes a two-wire, I²C-compatible serial interface with 3 address pins, allowing up to 8 devices on the same bus.
• Flexible Configuration: Each I/O port can be individually configured, providing flexibility for various application requirements.
• Wide Operating Voltage: Supports a broad range of supply voltages from 2.5V to 5.5V, making it suitable for both 3.3V and 5V systems.
• Interrupt Output: Features an interrupt output which can be configured to alert the host controller when input states change, reducing the need for constant polling.
• Low Power Consumption: Designed for power-sensitive applications with low standby current, contributing to overall energy efficiency.

Applications

The MAX7328AWE is highly adaptable and can be used in a variety of application areas including:

• Industrial control systems
• Server management
• Portable devices
• Automotive applications
• Home automation and smart appliances

Package and Reliability

This I/O expander is offered in a compact 16-pin WLP (Wafer-Level Package) or a 16-pin TSSOP (Thin Shrink Small Outline Package), providing options for space-constrained designs. Additionally, the MAX7328AWE is designed with Maxim Integrated's commitment to reliability and quality, ensuring stable performance across its operational temperature range of -40°C to +85°C.

With its combination of flexibility, ease of use, and Maxim Integrated's reputation for high-quality semiconductors, the MAX7328AWE is a smart choice for expanding I/O capabilities in your next project.
