EM9301

EM MICROELECTRONIC - MARIN SA EM9301 Single-Cell Battery Bluetooth Low Energy Controller Description The EM9301 is a low-voltage, low-power, fully-integrated, single-chip Bluetooth1 Low Energy (BLE) controller. It 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 allows operation using efficiently all kinds of batteries down to 1.9V. This feature provides the required voltage to the integrated low-power RF core. EM9301 can be ordered for all applications where a supply voltage from a typical 3V battery or from any other source is available in the system. 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 parameter. The EM9301 controller is designed to act as BLE master or slave according to the Bluetooth specification V4.1 (Declaration ID D025195). It can be controlled by any external microcontroller featuring BLE profiles and applications through the standard Bluetooth 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 SMAR...
