GR5526 Series
GR5526

The Goodix GR5526 family is a single-mode, low-power Bluetooth 5.3 System-on-Chip (SoC). It can be configured as a Broadcaster, an Observer, a Central, a Peripheral, and supports the combination of all the above roles, making it an ideal choice for Internet of Things (IoT), LE Audio, and smart wearable devices. In addition, it supports Bluetooth Low Energy (Bluetooth LE) Direction Finding: angle of arrival (AoA) and angle of departure (AoD), as well as LE Isochronous Channels.

Based on ARM? Cortex?-M4F CPU core, the GR5526 series integrates Bluetooth 5.3 Protocol Stack, a 2.4 GHz RF transceiver, on-chip programmable Flash memory, RAM, and multiple peripherals. GR5526 delivers a feature-rich display and graphics solution by providing the option of graphics acceleration (GPU + DC) and system-in-package (SiP) pseudostatic RAM (PSRAM) to accommodate display while still leaving plenty of resource for wearable schemes.
