Renesas Electronics has developed an AI accelerator that performs convolutional neural network (CNN) processing at high speeds and low power. A test chip with this accelerator has achieved the power efficiency of 8.8Tera operations per second per W (TOPS/W), which is the industry’s highest class of power efficiency, reports Renesas. The accelerator is based on the processing-in-memory (PIM) architecture, in which multiply-and-accumulate (MAC) operations are performed in the memory circuit as data is read out from that memory.

Smart amplifier enriches sound at low power, says Maxim Integrated
Integrating speaker protection to deliver up to 2.5 times loudness and two octaves of bass with the lowest quiescent power consumption of around 24mW, the MAX98390 5.1W dynamic speaker management (DSM) smart amplifier is announced by Maxim Integrated Products.
Analog Devices integrates electrochemical and impedance measurement
The AD5940 is an electrochemical and impedance measurement front end released by Analog Devices that enables the next generation of vital sign monitoring devices and intelligent electrochemical sensors. The AD5940 incorporates both potentiostat and electrochemical impedance spectroscopy (EIS) functionality on a single chip, allowing for sensor measurement in both time and frequency domains.
Pushbutton smart switches save power
Torex Semiconductor has launched the XC6193 and XC6194 pushbutton load switches.
