Infineon Targets Energy-Efficient Bluetooth 5.4 Low Energy Applications with Its Latest AIROC Chips
New parts target everything from Bluetooth Low Energy mice and headsets to wireless battery management — and more.
Embedded electronics specialist Infineon has launched a new range in its AIROC family, the AIROC CYW20829 Bluetooth Low Energy microcontroller (MCU), offering two Arm cores and Bluetooth 5.4 Low Energy connectivity — and with a variant, dubbed CYW89829, rated suitable for automotive projects.
"Infineon offers one of the industry’s broadest portfolios of IoT [Internet of Things] solutions," claims Infineon's Shantanu Bhalerao of the company's latest launch. "Our Bluetooth solutions offer robust connectivity and the latest features. "Our automotive AIROC CYW89829 Bluetooth LE MCU and versatile AIROC Bluetooth CYW20829 LE MCU deliver ultra-low power and a high degree of integration for a better user experience across various applications in automotive, industrial, and consumer markets."
The new chips, brought to our attention by CNX Software, are split into two key families: the CYW20829 family, currently in production, targets everything from Bluetooth mice to remote controls, gaming accessories, Bluetooth Low Energy (BLE) Audio products, and asset tracking projects; the CYW89829 family, sampling now, targets wireless battery management systems and automotive applications where reliability is key.
In both cases, the chips include two Arm Cortex-M33 processor cores — one for applications, running at 48MHz or 96MHz, and a 48MHz core dedicated to running the Bluetooth Low Energy stack. There's 256kB of static RAM (SRAM) on board but no flash memory in the CYW20829 range, with the chips relying instead on quad-SPI connectivity to an external flash module and supporting execute-in-place (XIP).
The radio stack supports the Bluetooth 5.4 Low Energy standard, including both angle-of-arrival and angle-of-departure (AoA and AoD) location tracking and up to 16 simultaneous connections of which four can be peripherals. There are three serial communication blocks that can be configured as I2C, SPI, or UART, two PDM audio channels and one I2S bus, and up to 32 general-purpose input/output (GPIO) pins with pulse-width modulation (PWM) support, a 12-bit sigma-delta analog to digital converter (ADC), 16-channel direct memory access (DMA), and a hardware true random number generator (TRNG) with cryptographic coprocessor.
