Digital pressure sensor’s ASIC lowers current consumption

A low current consumption model has been added to the HSPPAD series of digital pressure sensors for integration into smartphones, tablets and wearable devices. The HSPPAD042A has been developed in response to the need smartphones, tablets and wearable electronics using different kinds of software and applications which demand higher performance while increasing the power requirement. Sensors need to be not only power-efficient but also more compact given the higher number of parts integrated, says the company.

Magnetic sensor reduces power consumption and processing time

Designed for portable devices, the MMC3630KJ, is a small, BGA package, magnetometer, from Memsic. The magnetometer integrates a monolithic, three-axis AMR sensor and signal conditioning ASIC and is based on the company’s proprietary technology. The BGA package measures 1.2 x 1.2 x 0.5mm. It has a range of ±30G range, and more than five times better noise level compared to other technologies, says the company. With 600Hz magnetic sensing bandwidth, the magnetometer provides better than 10 accuracy in eCompass applications. The design also has drastically lower system level power consumption and processing time, claims the company. There is also a self-degaussing feature, which can eliminate the output drift due to temperature change and residual magnetic from ambient magnetic field. The series also includes an interruption feature, which can be used for motion detection and data acquisition ready notifications to lower system-level power consumption.

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.
