The Goodix GR533x series is a comprehensive-performance Bluetooth LE 5.3 SoC designed for various applications such as smart home, health care, smart trackers, and IoT modules, supporting Bluetooth Mesh networking protocols.
Based on Arm® Cortex®-M4F CPU core running at 64 MHz, the GR533x integrates a 2.4 GHz RF transceiver, Bluetooth LE 5.3 protocol stack, 512 KB on-chip Flash memory, 96 KB system SRAM, and a rich set of peripherals. It provides outstanding RF performance, featuring a maximum TX power of +15 dBm, an RX sensitivity of -99 dBm in Bluetooth LE 1 Mbps mode, achieving a total link budget of up to 114 dB.
With two main power supply schemes (DC-DC and SYS_LDO), the GR533x offers flexible options to achieve a balance between low power consumption and economical BOM.
