32bit flash microcontrollers double battery life

Based on the ARM Cortex-M0+ processor, the S1C31W74 microcontroller is sampling. This is Epson’s first in a new series of energy-efficient microcontrollers with integrated 32bit flash memory.
According to the company, the combination of the energy-efficient ARM Cortex-M0+ processor, and the company’s own low leak process and circuit technology helps to enable powerful microcontrollers with modest power requirements, thus extending battery life.
The S1C31W74 consumes only 900nA in RTC mode and 150µA/MHz in run mode, and can operate up to two times longer on battery power than one of the company’s original core 32bit flash microcontrollers. This energy efficiency is a step closer, says the company, to realising smart watches that do not require recharging and IoT terminals for environmental monitoring applications, where power consumption is a critical factor.
The microcontroller is a single chip, housed in a 1mm thick VFBGA8HX-181 package. The IC includes an LCD driver that can directly display up to 2,304 dots, a USB 2.0 full-speed device controller, 512kbytes of flash memory, and 128kbytes of RAM. It is also offered as a bare chip.
An optional evaluation kit includes an evaluation board, debug probe and an IDE, based on IAR Embedded Workbench for ARM.
The microcontrollers are sampling now, with volume production scheduled for July 2016.

Sensor can speed time to market for integrated modules

System designers can speed time to market for wearable and healthcare products, says Maxim Integrated Products, with the MAX30102 pulse oximeter and heart rate integrated sensor module. The integrated pulse oximetry and heart rate monitor module integrates red and IR LEDs to modulate LED pulses for oxygen saturation (SpO2) and heart rate measurements.

Imec and Cloudtag collaborate on frictionless, next-gen tracker

More lifestyle coaching than mere wearable devices, Cloudtag has launched its Cloudtag Track frictionless, wearable device, developed in collaboration with imec, the nanoelectronics research centre.
The fitness tracker combines fitness and health monitoring with design, it says, for fitness and the care, cure and prevention cycle by providing immediate access to medical data and personalised feedback.
imec developed algorithms for the medical technology company’s wearable sensor devices that enable accurate monitoring of physiological parameters. Cloudtag Track is its first wearable multi-sensor device. It is light and small, yet integrates a proprietary algorithm that retrieves physiological parameters with what the company claims is “an exceptionally high level of accuracy”. The algorithm recognises activity, measures energy expenditure, heart rate and other physiological data.
