Product Overview
The Goodix GR533x series is a Bluetooth Low Energy (Bluetooth LE) 5.3 System-on-Chip (SoC), suitable for IoT applications, 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, with a maximum TX power of +15 dBm, an RX sensitivity of -99 dBm in Bluetooth LE 1 Mbps mode, achieving an overall link budget of up to 114 dB.
With two main power supply schemes (DC-DC and system LDO), the GR533x offers flexible options to achieve a balance between low power consumption and economical BOM.
GR533x devices are offered in QFN32, QFN48, and BGA45 packages. The following table lists the detailed package configurations.
