Overview

The HS6621Cx family is a single-mode, low-power Bluetooth 5.1 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, the HS6621C integrates Bluetooth 5.1 protocol stacks, a 2.4 GHz RF transceiver, programmable Flash memory, RAM, and multiple peripherals.
HS6621Cx series includes HS6621CG, HS6621CQ, and HS6621CM.
