Japanese electronics company Renesas has introduced a Bluetooth Low Energy module for low-power IoT applications. It provides multi-standard wireless communications supporting Bluetooth Low Energy 5 and IEEE802.15.4 standards.
The RYZ012 is the company’s first Bluetooth Low Energy 5 module. It integrates a 2.4GHz RF transceiver supporting the IEEE802.15.4 multi-standard wireless protocol, Bluetooth Low Energy, Bluetooth LE Mesh and Zigbee.
Power draw is 0.4µA during deep sleep without SRAM retention, so users can extend battery life. A battery monitor measures battery capacity and detects low power in battery-operated devices.
“The RYZ012 module complements our IoT connectivity, featuring ultra-low power in a small form factor, designed to target a wide range of IoT, connected home, asset tracking and cost-sensitive applications,” said Roger Wendelken, senior vice president at Renesas. “The RYZ012 teams with Renesas’ sensors to offer an end-to-end, device-to-cloud ecosystem.”
The module supports the 2.4GHz IoT standards without the requirement for an external DSP. This reduces the number of external components required and the overall cost in system integration.
It includes a 32bit microcontroller with an integrated 512kbyte flash memory and 64kbyte SRAM for application support. There are two versions, with and without an integrated antenna. This allows for implementation flexibility and the option for longer wireless range requirements.
The module will be certified for use in the USA, Canada, EU and Japan.
Samples of both versions are available now, with full product availability later this year.
