SX1503I091TRT Description

Short technical summary and product information.

The Semtech SX1503I091TRT is a 16-channel General Purpose Input/Output (GPIO) expander designed for low-power handheld battery-powered equipment. It allows for serial expansion of I/O through a standard 400kHz I2C interface, providing additional control and monitoring capabilities when a microcontroller has insufficient ports.

 

This device supports an operating voltage range of 1.2V to 5.5V, with independent voltage operation for core and I/O banks. The I/O pins are 5.5V compatible and can sink up to 24mA. Key features include programmable pull-up/pull-down resistors, push-pull outputs, and mask-programmable interrupts with an open-drain active-low output. It also includes Power-On Reset (POR).

 

The SX1503I091TRT is housed in a compact 28-QFN-UT (4x4mm) package, suitable for surface mounting. It operates within a temperature range of -40°C to +85°C, making it suitable for various environmental conditions.
