The SmartConnect BTLC1000 from Microchip Technology is an ultra-low-power Bluetooth Smart (BLE 4.1) system-on-a-chip (SoC) with Integrated microcontroller (MCU), transceiver, modem, MAC, PA, TR switch, and power management unit (PMU). It can be used as a BLE link controller or data pump with external host MCU. When combined with external memory, it can also function as a standalone applications processor with embedded BLE connectivity. The qualified Bluetooth Smart protocol stack is stored in dedicated ROM and includes L2CAP service layer protocol, security manager, attribute protocol (ATT), generic attribute profile (GATT), and the generic access profile (GAP). Additionally, application profiles such as proximity, thermometer, heart rate, blood pressure, and many others are supported and included in the protocol stack.

The need for very few external components minimizes the total system solution cost. The BTLC1000 can be powered by several different battery types, ranging from coin-cell, AA, and AAA batteries to Lithium polymer batteries, without the need for external power management circuitry (V_BAT range = 1.8 V to 4.3 V). The BTLC1000 provides a cost-effective solution for many Bluetooth Smart based applications by integrating the BLE radio and baseband with an Arm Cortex-M0-based microcontroller. The rich feature set of the ATBTLC1000 makes it suitable for use in any Bluetooth, low-power, IoT application.
