Microchip Releases Arm Cortex-M23 Based Microcontroller

Microchip Technology has announces the release of a microcontroller (MCU) to combine a secure subsystem and Arm TrustZone technology in a single package. The PIC32CM LS60, which integrates Microchip’s Trust Platform secure subsystem, makes it easier to develop end products using one microcontroller rather than two or more semiconductor chips. Now, designers can go to one trusted source to find a 32-bit MCU that is designed to protect products and the end user from remote or physical attacks on their smart home devices, smartphone or tablet accessories, portable medical devices, wearables, connected appliances and industrial robots.

“With its integration of Arm TrustZone technology and Microchip’s secure subsystem in one package, the PIC32CM LS60 is an offering that the market hasn’t seen before,” said Rod Drake vice president of Microchip Technology’s 32-bit MCU business unit. “We believe this MCU’s security, ease of use and low power operation will be a powerful shift in implementing advanced security technology in IoT applications.”

With the increased adoption of touch capabilities in waterproof wearables and modern appliances, embedded designers are challenged with developing touch interfaces that work well in noisy and moist environments. The PIC32CM LS60 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.

In addition, the device features core-independent SleepWalking peripherals and the Event SystemThese 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. This makes it easier for customers to develop low-power applications and release extended-battery-life products to market faster.

In addition to the PIC32CM LS60 secure variant, a PIC32CM LE00 general-purpose variant and a PIC32CM LS00 Arm TrustZone technology variant (without secure subsystem) are also available. The PIC32CM5164LS60, PIC32CM5164LS00 and PIC32CM5164LE00 are available today in 10,000 units for the 100-pin TQFP package and are priced at $5.48, $4.33 and $4.18, respectively.
