DA14533

The DA14533 is a highly integrated, low-power Bluetooth 5.2 SoC from Renesas Electronics Corporation, designed for wireless connectivity in compact and battery-powered applications. It features an ARM Cortex-M0+ processor running at up to 48 MHz, providing efficient processing capabilities while maintaining ultra-low power consumption—ideal for wearable devices, IoT sensors, and smart home products. This SoC integrates a full-featured Bluetooth 5.2 radio compliant with the latest specifications, supporting extended range, high data rates (up to 2 Mbps), and improved coexistence with other wireless technologies. It also includes built-in memory with 512 KB of flash and 64 KB of SRAM, enabling standalone operation without external memory. The device supports multiple power modes—including active, sleep, and deep sleep—with current consumption as low as 1.5 µA in deep sleep, making it suitable for long-term battery life applications. The DA14533 offers extensive peripheral support, including UART, SPI, I2C, GPIOs, and a 12-bit ADC for analog signal acquisition. It also includes hardware acceleration for AES encryption and secure key storage, enhancing security for sensitive data transmission. A dedicated low-power timer and wake-up sources allow precise timing control and minimal power draw during idle states. Designed for ease of development, the DA14533 is supported by Renesas’ comprehensive software ecosystem, including the SmartSnippets™ SDK, which provides ready-to-use Bluetooth stack, drivers, and example projects. This accelerates time-to-market for developers building BLE-based solutions across consumer electronics, industrial monitoring, healthcare devices, and asset tracking systems. Its small 4 mm x 4 mm QFN package makes it ideal for space-constrained designs, while its robust performance ensures reliable operation in noisy RF environments. The chip’s flexibility allows it to function as a central or peripheral role in Bluetooth networks, supporting mesh networking when paired with compatible devices. With integrated power management and advanced low-power features, the DA14533 delivers a complete solution for modern wireless applications requiring high efficiency, scalability, and reliability.
