STLBC01 Bluetooth low energy controller Datasheet - production data Applications Watches VFQFPN 24L Fitness, wellness and sports Consumer medical Security/proximity Features Remote control Bluetooth specification v4.0 compliant master Remote sensing and slave BLE controller Home and industrial automation Bluetooth protocol stack for STM32L and Assisted living profiles provided separately Mobile phone peripherals Operating supply voltage from 1.9 to 3.6 V PC peripherals 13 mA maximum peak current allows standard coin cell battery usage Description Low power physical layer The STBLC01 is a very low power Bluetooth low Link layer with embedded security engine energy (BLE) controller compliant with Bluetooth UART and SPI available as HCI transport specification 4.0. The STBLC01 integrates a low layers power physical layer, a link layer with an SPI interface allows proprietary low power embedded security engine, a host controller mode to further reduce the power consumption interface (HCI), and a power management. The STBLC01 allows the meeting of the tight ISM 2.4 GHz frequency band advisable peak current requirements imposed by 1 Mbps on-air data rate the use of standard coin cell batteries, and even Wide spread and low cost 26 MHz Xtal in worst-case operating conditions 13 mA is the maximum current that is drawn from the input 200 differential impedance of antenna port voltage source. Yet ultra low power sleep modes Very small number of external discrete and very short transition time between operating components modes allow a very low average current Programmable output power from -18 dBm to consumption to be achieved, which results in +3 dBm longer battery life. The STBLC01 offers the possibility of interfacing with several external Digital RSSI microcontrollers using either UART or SPI as the Power management with integrated linear transport layer for HCI communications. regulator Battery level detector function to keep control Table 1.
