Arm Cortex-M23 Based Microcontroller Supported with Secure Key Provisioning Solutions for Industrial Robots and Wearables

Microchip Technology Inc. has announced the release of a new microcontroller PIC32CM LS60 that combines a secure subsystem and Arm TrustZone technology in a single package and is designed to protect products and the end-user from remote or physical attacks on their smart home devices, smartphones, or tablet accessories, portable medical devices, wearables, connected appliances, and industrial robots. Moreover, it integrates an enhanced peripheral touch controller with the Driven Shield Plus feature that prevents false touches due to moisture and provides high immunity to noise to enable exceptional touch interfaces.

This device features core-independent SleepWalking peripherals and the Event System. These peripherals keep the MCU core in sleep mode for extended periods to reduce power consumption. It also comes with on-chip analog that includes operational amplifiers (op amps), digital-to-analog converters (DACs), and analog-to-digital converters (ADCs) that can be operated in sleep modes and interfaced with a variety of sensors. The PIC32CM LS60 is compatible with the MPLAB Data Visualizer and Power Debugger tools that can be used to monitor, analyze, and fine-tune power consumption numbers in real-time.

Features

• Arm Cortex-M23 CPU running at up to 48 MHz

• 512/256 KB Flash

• 16/8 KB Data Flash Write-While-Read (WWR) section for non-volatile data storage
