Recently, Renesas Electronics launched the industry’s outstanding new Bluetooth chip — DA14533. This chip integrates a radio frequency transceiver, Arm® M0+ microcontroller, memory, peripherals, and security features into a compact system-on-chip (SoC) design. As the first device in Renesas’ low-power Bluetooth® SoC product family to achieve automotive-grade certification, the DA14533 features advanced power management capabilities that simplify system integration and reduce power consumption. With a certified Bluetooth Core Specification 5.3 software stack and extended temperature support, developers can quickly embark on diverse application development projects, including tire pressure monitoring, keyless entry, wireless sensors, and battery management systems.
Optimized Design for Superior Energy Efficiency
Based on Renesas’ leading position in low-power Bluetooth SoC (SmartBond Tiny product family) and the industry’s outstanding low-power technology, the new DA14533 incorporates the most advanced power management features in the industry: this product includes an integrated DC-DC buck converter that can precisely adjust the output voltage according to system requirements; under operational conditions, its system power consumption is significantly lower than that of competing products, requiring only 3.1mA during transmission and dropping to 2.5mA during reception; in sleep mode, the current is as low as 500nA. These power management and energy-saving features help significantly extend the lifespan of small battery-powered systems and easily meet the stringent power consumption requirements in tire pressure monitoring system task configurations.
AEC-Q100 Automotive Grade Certification with Latest Security Features
The DA14533, as a product compliant with AEC-Q100 Grade 2 standards, means it has passed rigorous testing to ensure exceptional quality and reliability in extreme automotive environments. Additionally, the product’s extended temperature range (-40 to +105°C) further guarantees reliable performance under harsh conditions, making it an ideal choice for systems in automotive, industrial, and other fields that demand high stability and durability. This product complies with Bluetooth Core Specification 5.3 and includes the latest security features to protect connected devices from various threats.

Chandana Pairla, VP of Connectivity Solutions Division at Renesas stated: “Our SmartBond Tiny SoC product family has achieved significant success in the industrial market, with over 100 million units shipped to date. This brand-new automotive-grade product will help the next generation of battery-powered automotive and industrial systems explore new frontiers in low-power Bluetooth applications, fully meeting the stringent requirements for high energy efficiency, compact size, and broader temperature adaptability in these applications.”

Reduce BOM, Lower Costs, and Simplify Development
Similar to other low-power Bluetooth SoC devices in the SmartBond Tiny product family, the DA14533 requires only six external components, providing a best-in-class engineering bill of materials (eBOM).
A single external crystal (XTAL) is used for both operational and sleep modes, eliminating the need for a separate oscillator for sleep mode. The ultra-compact design in a WFFCQFN 22-pin 3.5mm x 3.5mm package makes it the smallest automotive-grade low-power Bluetooth SoC on the market. Thanks to its compact design and simplified eBOM, this product can be seamlessly integrated into space-constrained systems, thereby reducing overall system costs and shortening time-to-market for customers.
