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.

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.

Microchip launches MCU families

Microchip has launched the SAM D5x and SAM E5x MCU families. Both 32bit MCU families are said to provide extensive connectivity interfaces and robust hardware-based security for a variety of applications.

MCUs feature on chip digital filter

STMicroelectronics has begun volume production of its STM32L45x MCU range. According to the company, devices in the STM32L451, STM32L452, and STM32L462 lines integrate a digital filter for Sigma-Delta modulators, enabling audio capabilities such as noise cancellation or sound localisation on an inexpensive microcontroller.

SiP blends MCU and sub GHz radio

The SAM R30 from Microchip is a system in package (SiP) device integrating a SAM L21 microcontroller alongside an IEEE802.15.4 sub GHz. According to the supplier, the SiP delivers design flexibility and proven reliability, making it suitable for connected home, smart city and industrial applications.

Bluetooth low energy portfolio expanded

Delivering more available memory, Bluetooth 5-ready hardware, automotive qualification and an ultra-small wafer-chip-scale package option, the CC2640R2F and CC2640R2F-Q1 have been added to Texas Instruments’ scalable SimpleLink Bluetooth low energy CC264x wireless MCU family.
