Microcontrollers

Microcontrollers – whether 8, 16 or 32bit – are all around us: at home, at work, in our cars and in industrial systems. Reflecting this abundance, the market for microcontrollers is worth more than $16billion a year and growing strongly.

The market was once dominated by 8bit parts, but the price performance advantage of ARM based 32bit devices, along with the need to accommodate more complex software, is starting a move from 8bit to 32bit mcus. And this is accompanied by the appearance of multicore devices.

In this section, New Electronics brings you the latest on the microcontroller market.

Amazon Alexa technology brought to simple connected objects

The X-CUBE-AVS software package from STMicroelectronics enables Amazon’s Alexa Voice Service (AVS) to run on STM32 microcontrollers, allowing simple connected objects to support advanced conversational user interfaces with Cloud-based intelligence like automatic speech recognition and natural-language understanding.

NFC smart sensor IC

ams has introduced the AS39513, an NFC sensor tag and data logger IC for smart labels which will enable more efficient and accurate monitoring of the condition of assets such as food and healthcare products in storage and in transit.

ROHM announces first noise-tolerant op-amps

ROHM Semiconductor is now offering automotive-grade op-amps featuring superior noise immunity. With its BA8290xYxx-C series output voltage fluctuations are suppressed in all frequency bands to less than ±1%, compared to ±3.5% to ±10% with conventional products.

16bit MCU range expanded

Epson is shipping samples of the S1C17M2x family of low power 16bit MCUs with on-chip flash. According to the company, the MCU is suited to applications ranging from home appliances to factory automation.

Low cost, ultra low power MCUs

Texas Instruments has introduced what it says are its lowest-cost ultra-low-power MSP430 MCUs for sensing applications. The latest additions to the range are the MSP430FR2000 and MSP430FR2100, with 500byte and 1kbyte of memory, respectively, along with a new development kit (pictured).

Cypress’ PSoC 6 BLE Pioneer Kit now available

Cypress Semiconductor has released the PSoC 6 BLE Pioneer Kit and PSoC Creator Integrated Design Environment (IDE) software version 4.2 supporting designers to use the company’s PSoC 6 microcontroller (MCU) when developing IoT applications.
