Product Overview

The Goodix GR5525 series is a single-mode, low-power Bluetooth 5.3 System-on-Chip (SoC). It can be configured as a Broadcaster, an Observer, a Central, and a Peripheral and supports the combination of all the above roles, making it an ideal choice for Internet of Things (IoT) and smart wearable devices.

Based on Arm® Cortex®-M4F CPU core running at 96 MHz, the GR5525 integrates a 2.4 GHz RF transceiver, Bluetooth LE 5.3 protocol stack, on-chip programmable Flash memory, 256 KB system SRAM, and a rich set of peripherals, enhanced I2C/UART port number for sensor applications, as well as expanded I/O functionality. The GR5525 MCU enhances QSPI interface to support external RAM (PSRAM) to accommodate display while still leaving plenty of space for wearable schemes.

GR5525 series are offered in both QFN68 and QFN56 packages. The table below lists the detailed package configurations.
