MCUs and expansion for IoT

Renesas Electronics has expanded its Synergy Platform. The platform was designed to accelerate time to market, reduce total cost of ownership, and remove obstacles engineers face when designing devices for the IoT.

The expansion includes the launch of the S124 group of Synergy micro-controllers (MCUs) with low power operating characteristics and precise analog signal acquisition/generation capabilities ideal for sensor applications. In support of these MCUs is an updated version of the Synergy Software Package (SSP) and the e2 studio Integrated Solution Development Environment (ISDE) tool. The SSP and e2 studio tool also incorporate further enhancements adding capabilities for networking, industrial automation, power management, and automated configuration.

Synergy MCUs in the S124 group are based on Renesas' proprietary technology consuming just 70,3 µA per MHz of MCU clock speed. These MCUs carry 14-bit analog-to-digital converters, 12-bit digital-to-analog converters, and low power comparators.

User interface applications are supported with more than 30 channels of capacitive touch sensing inputs. The connectivity is expanded by USB-FS and CAN interfaces, plus safety and security are assisted with on-chip support for SRAM parity checking, a NIST-compliant True Random Number Generator (TRNG), and AES-256 cryptography with chaining. MCU packages measure 4 mm x 4 mm for space-constrained end-products. Possible applications include edge-node IoT sensors, home appliance control, and point-of-sale terminals.

Development support for the MCUs and the DK-S124 development kit is provided in SSP version 1.1.0 and e2 studio version 5.0. The SSP v1.1.0 has specific optimizations for the ThreadX real-time operating system (RTOS) and the USBX communication stack to work within the S124 MCU's smaller memory sizes.

SSP v1.1.0 also includes enhancements for IPv6 networking and services for connected devices, BSD-compatible socket layer support, support for SSI audio, and CAN communications, plus several additions to the application framework.

The Synergy Platform expansion continues globally with the addition of five Verified Software Add-on (VSA) products from Europe and Japan to be available on in spring 2016. VSA software from third-parties are verified by Renesas to be SSP-compatible. Global VSA partners address specialized functions in the areas of home and industrial automation including Echonet, CANopen, and BACnet, plus secure communications, and cloud services.
