Redpine Signals Inc. has launched a multiprotocol wireless MCU that it claims is the lowest power in its class of device and one of the smallest.

The RS14100 supports Bluetooth 5, dual-band Wi-Fi (2.4 and 5GHz), 802.15.4/ZigBee/Thread and is based around a Cortex-M4F processor core and includes a Redpine-developed network security processor. The power consumption on standby either in Bluetooth or WiFi is less than 50microamps. The processor also includes high performance mode of 180MHz that consumes 32microamps/MHz and a low power mode that consumes 15microamps/MHz up to 32MHz.

This makes the RS14100 suitable for battery operated Internet of Things applications, according to Redpine. Typical applications could include security cameras, smart locks, video doorbells, fitness bands, industrial sensors and location tags.

The device is available as an SoC in chipscale packaging measuring 3.5mm by 3.5mm and 0.3mm deep or as a module with passives and RF circuitry measuring 4.6mm by 7.8mm and 1mm deep. The RS14100 features includes up to 4 MB of flash for applications.

Redpine has also launched the RS9116 wireless solution, featuring multi-protocol wireless connectivity. RS9116 will be available in both hosted (n-Link) and embedded (WiSeConnect) configurations. The RS9116 is similar to the RS14100 but does not have the Cortex-M4F core and will normally be run alongside a host processor or MCU. The network-security processor within the RS9116 can be used to run wireless protocols.

The WiSeConnect embedded modules provide a data throughput of over 90Mbps with integrated wireless stacks, wireless profiles as well as networking stack. n-Link hosted modules interface to processors running Linux, Android or Windows operating systems.

The R14100 is based on trusted execution environment architecture with the security processor separated from applications processor, PUF (Physically Unclonable Function) based root-of-trust, Suite-B Crypto HW accelerators, secure boot, secure firmware upgrade, secure XIP and secure peripherals. The RS14100 also supports a rich set of digital and analog peripherals including CAN, Ethernet, eMMC/SD Card, OpAmp, ADC, DAC and USB OTG.

The RS14100 and the RS9116 SoC and modules are implemented in 40nm CMOS and are sampling now with volume production starting in 2Q18.
