ON Semiconductor announces a tonic for SiP

17 September 2014

A semi-customisable, power-efficient SiP enables miniature sensing systems for portable, mobile medical, health applications.

In response to evolving product demands within the portable medical market, ON Semiconductor has introduced Struix.

The semi-customisable System-in-Package (SiP) is for precision sensing and monitoring in a variety of mobile medical electronics including glucose monitors, heart rate monitors and electrocardiogram analysers.
Die stacking technology is used to integrate a custom-designed analogue front-end on top of a 32bit ASSP (the ULPMC10). By using standard and customisable components, the SiP offers medical device manufacturers the flexibility to create medical sensor interface applications while improving time-to-market and cost-effectiveness, according to the company.
The ULPMC10 microcontroller processes signals using a 32bit ARM Cortex-M3 core capable of running up to frequencies of 30MHz. It incorporates 512kbyte on-chip Flash memory and 24kbyte SRAM to store critical program and user data. Designed to improve battery life in portable devices, ULPMC10 places minimal dynamic and static power demands, says the company. Through on-chip charge pump-based power conversion and regulation, the microcontroller can operate at a current consumption of less than 200 µA/MHz. While in standby mode, current consumption remains below 500nA, a critical parameter for low-duty cycle medical devices.
The microcontroller also includes a12bit ADC with three multiplexed inputs, a real-time clock, a phase-locked-loop, and a temperature sensor. There is also a suite  of development add-ins for IAR Systems to support the ULPMC10 microcontroller, including CMSIS based software interfaces.
