Infineon opens up Apple ‘find my’ network with secure wireless chips, microcontrollers
Infineon Technologies has added support for the Apple Find My network accessory to its development kit.
The support in the ModusToolbox allows the AIROC CYW20829, PSOC 63 Bluetooth microcontroller (MCU), AIROC CYW5591x Wi-Fi/BT connected MCU and AIROC CYW5551x to use the Bluetooth technology. This allows developers to easily access the Find My network.
This network is made up of over a billion Apple devices that provides an easy, secure way to locate compatible personal items using the Find My app on iPhone, iPad, Mac, or using the Find Items app on Apple Watch.
This was previously accessible only to items that had an Apple AirTag attached. Anyone could purchase an Apple AirTag and attach it to something of value. The AirTag sends out a secure Bluetooth signal that nearby Apple devices in the Find My network can detect. These devices then anonymously transmit the location of the AirTag to iCloud, allowing the user to use the Find My app on their iPhone, which would show it on a map.
Apple’s Find My network accessory program has opened the network to third-party device manufacturers to build products to use the service. Infineon sees the Find My functionality being added to e-bikes, power tools and fitness trackers as well as key fobs, smart watches, voice recorders and smart glasses without the need for the tags.
“Apple Find My opens up a completely new feature for all Bluetooth IoT devices – the ability to locate them with your iPhone, iPad, Mac, or Apple Watch. We are excited to be part of this program with our Bluetooth and Wi-Fi connected MCUs,” said Shantanu Bhalerao, VP of Wireless Product Line at Infineon.
The CYW20829 MCU integrates a 96MHz ARM Cortex-M33 MCU and a secondary ARM Cortex-M33 dedicated for the Bluetooth controller. CYW20829 comes with 256 KB of application SRAM, an XIP capable Quad SPI interface to allow a flexible selection of external Flash, and a diverse range of peripherals, including CAN FD, PDM, I2S, ADC, timers.
The PSOC 63 MCU with AIROC Bluetooth Low Energy (LE) has dual-core 150MHz ARM Cortex-M4 and 100MHz M0+ core for AI/ML Edge applications with programmable analog front ends, CAPSENSE touch sensing user interface, and Bluetooth LE radio. The PSOC 63 supports configurable MCU peripherals with 84 programmable GPIOs and six overvoltage-tolerant capable pins, making it suitable for a wide range of IoT applications.
The CYW5591x WiFi/BT controller supports single/dual/tri-band Wi-Fi 6E, Bluetooth Low-Energy 5.4 with ARM TrustZone, PSA Level 2 certifiable and matter support. The device is optimized for IoT including smart home, industrial, and portable devices, and can be used by itself or to offload connectivity from a host processor. The CYW5551x is aimed at smart home, wearables, and small form-factor applications with a cost-effective balance of wireless and power for IoT connectivity.
The AIROC devices have a common software framework across Android, Linux, RTOS platforms and are pre-integrated with the ModusToolbox software and tools.
