Whitepaper: Lower your power consumption for battery-operated smart devices
As the number of connected smart home devices grows, striking the right balance between battery-life and the customer experience is tough for device makers. This problem gets more complicated as customers look for new ways to retrofit their homes with IoT devices without power cabling.
These challenges leave device makers in search of new ways to make their battery-operated smart home products more power-efficient at all levels, while still enabling the devices to quickly respond to customer needs. Wireless design choices can either enhance or hurt customers’ user experience.
This white paper identifies the top issues and considerations for connected smart home battery-operated devices. Using a case study of an Internet Protocol (IP) camera design, we will examine design principles that can be applied for lowering power consumption on battery-operated smart home applications significantly. These same design principles also could be applied to other applications such as smart doorbells, smart door locks, and smart thermostats.
AIROC™ CYW43022: Ultra-low-power solution for IoT applications needing long battery life
AIROC™ CYW43022 1x1 dual-band (2.4/5 GHz) Wi-Fi 5 (802.11ac) + Bluetooth® 5.4 is an ultra-low-power connectivity device designed to address IoT designs needing minimal power consumption and compact size. Applications such as wearables, IP cameras, and smart door locks are ideally suited for CYW43022 with its low transmit/receive power and optimized Deep Sleep mode. An embedded Bluetooth® stack and Wi-Fi networking offloads allow CYW43022 to save system-level power by handling Bluetooth® and Wi-Fi connectivity activity without the involvement of a host processor.
AIROC™ CYW43022 supports Linux, Android, and RTOS designs, with the ability to pair with Infineon’s ultra-low-power, flexible, and secure PSoC™ 6 MCUs within ModusToolbox™ software and tools as well as third-party A-Class and M-Class MCUs.
Key Benefits:
- Ultra-low-power for applications maximizes battery life
- Embedded Bluetooth® stack and Wi-Fi network offloads
- Optional internal 32-kHz low-power oscillator saves power and BOM costs
- Dual-band (2.4/5 GHz) helps manage congestion
- +20dBm Bluetooth® transmit power for applications with limited antennas
- Built on market-proven wireless IP – maximum interoperability
- Supports concurrent Wi-Fi and Bluetooth® connectivity use cases and coexistence
- Reduction in development time with Wi-Fi software enablement for RTOS, Linux, and Android designs with multiple hosts supported
- Rapid time-to-market with multiple partner modules integrating AIROC™ CYW43022 with full global certifications, reference platforms, and more
- Direct access to online application support engineers in the Infineon Developer Community
Applications:
- Smart home - IP cameras, smart doorbells, smart door locks, smart thermostats
- Wearables - Smart watches, fitness trackers, AR glasses
- Smart medical/healthcare - Blood pressure monitors, portable medical monitors
Modules and EVKs:
For faster time-to-market, Infineon works with proven module partners to develop module based solutions. The Murata Type 2GF is a small and high performance module based on the AIROC™ CYW43022 combo chipset which supports Wi-Fi 802.11a/b/g/n/ac + Bluetooth® 5.4 BR/EDR/LE up to 78Mbps PHY data rate on Wi-fi and 3Mbps PHY data rate on Bluetooth®. 2Mbps LE PHY is also supported. The WLAN section supports SDIO v2.0 SDR25 interface and the Bluetooth® section supports high-speed 4-wire UART interface and PCM for audio data.
To begin evaluation, Embedded Artists offers the 2GF M.2 module evaluation board (EAR00497) designed for evaluation, integration, and ease-of-use, making it even easier to integrate certified modules into your next design. This board is ideal for the measurement of wireless performance and for development.
