Apogee Semiconductor API016 Rad-Hard I/O Expander

Introduction

The Apogee Semiconductor API016 Rad-Hard I/O Expander is a cutting-edge component designed for robust and flexible I/O expansion in radiation-hardened environments. With its ability to handle varying supply voltages and support for both I2C and SPI interfaces, this device is ideal for applications in space and other high-radiation environments.

Part Description

The API016 I/O Expander features a unique architecture that supports two independent supply rails: VCCI for powering the serial interface logic and VCCP for the I/O ports. This design allows for seamless interfacing between low-voltage microcontrollers and higher-voltage peripherals. The device operates with voltage levels ranging from 1.4V to 5.5V and includes advanced features such as level translation, internal power-on reset, and fault detection. It is radiation-hardened against Single Event Effects (SEE) and is suitable for both Low Earth Orbit (LEO) and Geostationary Orbit (GEO) missions.
