General description
The EM9301 is the first generation of low voltage and low power, fully integrated single-chip Bluetooth Low Energy (BLE) controller.

EM9301 features a low power physical layer, a link layer with an embedded security engine, a Host Controller Interface (HCI), and a powerful power management which allow operations using efficiently all type of batteries down to 0.8V. This feature is achieved thanks to the embedded high efficiency DC/DC up converter which provides the required voltage to the integrated low power RF core. Moreover, the DC/DC up converter is designed to support an external load current and can be used to supply low-power microcontrollers or sensor interfaces.

EM9301 can also be ordered without DC/DC converter, for all applications where a supplied voltage from a 3 V battery or any other source is available in the system. In this case, the bill of material is further reduced, since no additional coil for the DC/DC up converter is needed.

This BLE controller offers performances tailored for extremely low-power applications. Furthermore, the minimum amount of external components required makes the EM9301 suitable for applications where the form factor is a fundamental partner.

The EM9301 is designed to act as BLE master or slave according to the Bluetooth specification V 4.0. It can be controlled by any external microcontroller featuring BLE profiles and applications, through the standard BT HCI interface. UART and SPI interfaces are available as HCI transport layers. Moreover, during the intervals with no active BLE RF connection, the EM9301 features a proprietary low-power mode which can further reduce the power consumption.

With its high level of flexibility, the EM9301 is the best choice for a Bluetooth low energy companion chip.
