Development kits based on Arm Cortex-M23 target IoT

Distributor RS Components introduces Microchip microcontrollers and development kits for IoT and touch-control applications. The microcontrollers and kits are based around Microchip’s Arm Cortex-M23-based SAM L10 and SAM L11 family of 32-bit microprocessor and integrate Microchip’s picoPower technology.

The Microchip microcontrollers are suitable for applications as wide ranging as the IoT and security-in-home automation or smart agriculture, and ultra-low-power applications such as energy harvesting and other low-power industrial use. The devices are also suitable for capacitive touch control applications such as remote controls, automotive door handles or industrial keypads, adds RS Components.

The low-power SAM L10 and SAM L11 microcontrollers have a smaller code size compared to Arm Cortex M0+-based devices and have achieved an EEMBC ULPMark certified benchmark score of 405, which is more than 200% higher than the nearest competitor devices, claims RS Components.

The SAM L11 microcontrollers have a range of security features including Arm TrustZone, chip-level tamper detect, crypto-acceleration with AES128 and SHA256 encryption, secure boot and bootloader and secure key storage. TrustZone protects network nodes from remote software attacks, by partitioning the main processor into secured and non-secure zones for LoRA or SigFox low-power wireless nodes, or in access control, or in automated systems with connected thermostats, for example.

Both microcontroller families integrates capacitive-touch and picoPower technology, claimed to deliver both high performance and low-power consumption, improving battery life and lowering overall system cost. The microchips have a low active current of less than 25 microA per MHz and standby RAM retention of less than 0.6 microA. Off mode consumption is less than 100nA and wakeup times are 1.5 micro seconds from idle mode and 2.6 micro seconds from sleep mode.

Both are configured with a 32MHz Cortex-M23 microprocessor core with up to 64k flash memory and up to 16k SRAM. Key peripherals include enhanced PTC, 12-bit ADC, 10-bit DAC, op amps and Sercom serial interfaces. Package options include TQFP, QFN, WLCSP and SSOP. Temperature options include -40 to +85 degrees C and -40 to +125 degrees C.

RS is also stocking Microchip’s Xplained Pro development kits, based around the SAM L10 and SAM L11 microcontrollers.

The Microchip SAM L10 and SAM L11 MCUs and Xplained Pro kits are shipping now from RS in the EMEA and Asia Pacific regions.
