GR533x Series
GR533x Series

The Goodix GR533x series is a Bluetooth Low Energy (Bluetooth LE) 5.3 System-on-Chip (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 excellent RF performance, with a maximum of +15 dBm TX power, -99 dBm RX sensitivity, and a maximum of 114 dB link budget in Bluetooth LE 1 Mbps mode.

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.

Notes:
[1] 1M-PHY, 2M-PHY, and Long Range are supported by default.  [2] GR5332 is now using the same Starter Kit as GR5331, so the +15dBm TX power and -99 dBm@1 Mbps RX sensitivity features are not supported on the Starter Kit.
