490pcs EM MICROELECTRONIC EM9301V02LF24D+ Bluetooth low energy controller

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. EM9301 can be for all applications where a supply voltage from a typical 3V battery or from any other source is available in the system with a small bill of material..
This BLE controller offers performances tailored for extremely lowpower 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 SMART 1 product.
