NXP SSTUM32865ET: Ultra-Low Power, High-Performance I2C-bus Fm+ 20-bit GPIO Expander

The NXP SSTUM32865ET is a state-of-the-art, high-performance I<sup>2C-bus Fm+ 20-bit GPIO expander designed to provide additional GPIOs with enhanced capabilities for microcontrollers and microprocessors in a wide range of applications. This device is particularly well-suited for battery-operated and power-sensitive applications due to its ultra-low power consumption.

Featuring 20 I/O ports that can be independently configured as either inputs or outputs, the SSTUM32865ET offers a flexible solution for system designers looking to expand the I/O capabilities of their designs without increasing the footprint. Each I/O port is equipped with high-current drive capability and includes robust ESD protection, ensuring reliable operation in harsh electrical environments.

The device operates over a wide voltage range from 1.65V to 5.5V, making it compatible with most logic levels and allowing for easy integration into a variety of systems. The SSTUM32865ET supports the Fast-mode Plus (Fm+) I<sup>2C-bus interface, which allows for higher data transfer speeds of up to 1 Mbit/s, enhancing system performance and responsiveness.

Additional features of the NXP SSTUM32865ET include an integrated power-on reset circuit, which ensures that all I/Os are initialized to a known state upon power-up. The device also offers an interrupt output feature that can be configured to alert the host controller when input levels change, thereby reducing the need for continuous polling and further conserving system power.

For ease of use, the SSTUM32865ET is available in a TSSOP24 package, which is suitable for automated assembly processes and space-constrained applications. The robust design and industry-standard packaging make this GPIO expander an excellent choice for expanding I/O capabilities in automotive control units, industrial automation, mobile devices, and any other system that requires additional I/Os without compromising on power efficiency or performance.

In summary, the NXP SSTUM32865ET combines ultra-low power consumption with high-speed I<sup>2C interface and a versatile I/O expansion capability, making it an ideal choice for designers who need to enhance the functionality of their systems while maintaining power efficiency and reliability.
