Designed to enable the integration of ultra-low power communications in SoCs targeting wearables, IoT and other long battery life connected devices that need to be cost-sensitive, Imagination Technologies has announced the first members of its Ensigma Whisper flexible connectivity IP family.
ICs & Semiconductors
Programmable mixed-signal matrix ICs conserve power
The fourth generation of GreenPAK mixed-signal matrix ICs have been released by Silego. The GPAK4 family of NVM programmable CMIC devices enables designers to integrate system functions such as comparators, ADCs, logic, delays, counters, resets, power sequencing, voltage sensing, and interface circuits, while minimising component count, board space, and power consumption.
LDO regulator ICs meet extended battery needs
LDO regulator ICs from Toshiba are available in a small package and are suited to a variety of mobile devices that require extended battery lives and high-density board assembly, including wearable devices, smartphones, tablet PCs and portable games.
The 200mA output TCR2LN/LE/LF series features ultra-low quiescent bias current and low dropout voltage.
They are available in fixed output voltages between 0.8 and 3.6V and feature over-current protection and an auto-discharge option. Using a fine analogue IC process for advanced CMOS, they realise low bias current characteristics by reducing the bias current to 2µA (max) in comparison to the existing TCR2EN series.
The ICs are available now, in small SDFN4 (0.8 x 0.8 x 0.38mm) and general purpose SOT-553 and SOT-25 packages.

Compact pressure sensor IC operates over wide temperature range
Piezo-resistive pressure sensors from Rohm are claimed to have class-leading pressure accuracy and stable measurement at both low and high temperatures due to a built-in temperature correction function.
