EM9305V01 BLUETOOTH® MODULE
USER MANUAL

DESCRIPTION

The EMREF9305QFN EM9305 Bluetooth® low energy module is a small size module embedding the EM9305 Bluetooth® low energy chip in QFN package from EM Microelectronic. It has an efficient PCB antenna and one of the lowest power consumption available.
The EM9305 is a tiny, ultra-low power and high performance Bluetooth 5.3 low energy chip. Its highly flexible architecture allows it to act as a companion IC to any ASIC or MCU-based product, or as a complete System-on-Chip (SoC). Its flexibility also allows it to be used with other protocols such as 802.15.4 MAC (ZigBee and Thread), BLE-mesh or other compatible proprietary protocols. Custom applications can execute on an efficient 32-bit ARC processor from a 512kB flash using a cache and DMA to optimize power consumption. DSP and floating-point units can be exploited to implement advanced audio and tracking algorithms.

CLASS B DEVICE NOTICE

NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or televi sion reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
