Bluetooth 5.3 SoC reduces power consumption in automotive applications

Mouser Electronics, Inc. now stocks the DA14533 Bluetooth 5.3 SoC from Renesas Electronics. Featuring advanced power management capabilities, the Bluetooth SoC simplifies integration, decreases power consumption, and lengthens the operational life of small-capacity, battery-powered systems. The SoC is automotive-qualified and appropriate for applications including tyre pressure monitoring (TPMS), keyless entry, onboard diagnostics (OBD), industrial automation, and telematics.

The SoC includes a 2.4GHz transceiver, an Arm Cortex-M0+ MCU, a wide range of peripherals, and the latest security features. It features 64kB RAM, 160kB ROM, and 12kB of one-time programmable (OTP) memory. An integrated low IQ buck converter accurately adjusts the output voltage according to system requirements and remains active in sleep buck mode. The SoC reduces the engineering bill of materials (eBOM) and simplifies development, requiring only six external components and featuring a single external oscillator (XTAL) for both active and sleep modes. Delivered in a WFFCQFN 22-pin 3.5mm x 3.5mm package, the device is one of the smallest automotive Bluetooth SoCs on the market and an excellent choice for space-constrained systems. The SoC is also AEC-Q100 Grade 2 automotive-qualified with an operating temperature range of -40C to +105C, ensuring reliable performance in harsh automotive and industrial environments. The SoC operates with coin-cell batteries and features built-in AES encryption and decryption, TRNG, and debug capabilities.

The company offers DA14533 development tools to evaluate the device's performance. The DA14533-00RNDEVKT-P pro-development kit includes a pro-motherboard, which provides a USB port to supply power and for interfacing with a PC running the evaluation software. The pro kit also consists of a pro-daughterboard with a pre-mounted DA14533 SoC and an embedded antenna. The pro-daughterboard is also sold separately as DA14533-00RNDB-P for users who already have the pro-motherboard.
