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.

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.

Low power 16bit MCU family launched

The PIC24 GA7 family of microcontrollers from Microchip is said to feature the lowest cost 256kbyte 16bit MCU currently available and suggests the parts will find application in IoT sensor nodes, portable medical devices and industrial control.

Socionext makes 24-core ARM server processor

Socionext, a supplier of SoC-based solutions, has introduced a new ARM-based multi-core processor. The ‘SC2A11A’ SoC Integrates 24 cores of ARM Cortex-A53 on a single die, and is intended to address the needs of growing applications such as data centre servers for online service providers and edge computing in IoT (Internet of Things) systems.

Microchip launches 8bit AVR MCUs with CIPs

A new generation of 8bit tinyAVR microcontrollers has been introduced by Microchip. The four devices range from 14 to 24 pins and are claimed to be the first tinyAVR MCUs to feature core independent peripherals. The devices will be supported by START, an online tool for the graphical configuration of embedded software projects.

MCU has built in memory LCD controller

Seiko Epson is sampling the S1C31D01, an energy efficient 32bit microcontroller based on the ARM Cortex-M0+ core. According to the company, the S1C31D01 is the first MCU to have a built in memory LCD controller.

Low cost 32bit MCU rapid prototyping boards

Two low cost rapid prototyping boards for 32bit applications have been launched by Microchip. The PIC32MX and PIC32MZ Curiosity Boards are said to include an integrated programmer debugger and to be fully incorporated into the company’s MPLAB X Integrated Development Environment.

Microcontrollers complete with core independent peripherals

The PIC18F K40 family of MCUs from Microchip consists of 10 devices ranging from 16 to 128kbyte of flash with package options covering 28 to 64 pins. The 8bit MCUs are claimed to be the first PIC18 product family to offer core independent peripherals (CIPs). The devices are suited for a broad range of applications and market segments, including touch sensing, industrial control, consumer, automotive and the IoT.

Lowest power, cost-effective PIC32 family with core independent peripherals

Microchip Technology has announced the company’s lowest power and most cost-effective family of 32-bit PIC32 microcontrollers (MCUs). The Microchip PIC32MM family is claimed to bridge the gap between the company’s PIC24F XLP and PIC32MX families. The family is said to be the first PIC32 to feature core independent peripherals, designed to offload the CPU for lower power and lower system design. The PIC32MM devices are supported by the Microchip MPLAB Code Configurator (MCC) to help simplify and accelerate designs.

16bit MCU for hand held card readers

Epson is sampling the S1C17M10, a low power 16bit microcontroller with 16kbyte of flash and 4kbyte of ROM. The device is said to halve operating current while quadrupling operating speed in hand held card reader tokens.
