RSL15 - ultra-low-power Bluetooth LE connectivity

For wireless telemetry and short-range links, onsemi’s RSL15 is a secure Arm Cortex-M33 Bluetooth Low Energy 5.2 wireless MCU - the industry’s lowest-power flash-based secure BLE device. Built-in direction finding and nanoamp-class sleep currents let battery-powered drone nodes locate one another precisely and stay dormant between transmissions, extending flight and sensor runtime.

• Bluetooth LE 5.2 with Angle of Arrival (AoA) and Angle of Departure (AoD) for direction finding and localization
• Ultra-low standby power: ~36 nA sleep (GPIO wakeup) and ~81 nA (RTC timer wakeup) at 3 V
• Smart Sense mode keeps sensors and the ADC active at nanoamp-level system power (continuous ADC ≈ 186 nA)
• Long Range (Coded PHY), 2 Mbit high-speed PHY, and up to 10 simultaneous connections
• Secure by design with Arm TrustZone and CryptoCell-312, secure boot, and root of trust<

Signal Conditioning

onsemi rounds out the signal chain with a broad portfolio of operational amplifiers, current-sense and instrumentation amplifiers, high-speed comparators, and LDO regulators for conditioning sensor and telemetry signals - offering low offset voltage, low noise, high common-mode rejection, and low-quiescent-current options well suited to battery-powered designs. Its Treo analog and mixed-signal platform advances these devices for battery-specific applications: built on a 65 nm Bipolar-CMOS-DMOS (BCD) process, Treo combines bipolar precision, CMOS control, and DMOS power handling on a single die, spans the industry’s widest 1–90 V supply range, and drives lower quiescent current and smaller system size - so amplifiers, comparators, and LDOs deliver precise, efficient conditioning while maximizing battery life.

NCV7192 takes that conditioning right to the sensing element: it is a bridge signal conditioning interface that amplifies a resistive bridge’s differential output with programmable gain and offset, uses an integrated DSP to correct bridge nonlinearity and temperature drift, and reports the result as a digital SENT message or a ratiometric analog signal. A second channel measures an external NTC so medium temperature travels alongside the pressure or force reading, while on-chip EEPROM - programmable through the output pin - holds calibration coefficients and customer data. Built-in diagnostics and protection against shorts, overvoltage, and reverse voltage make it suitable for safety-related sensing such as pressure, load, and flow measurement across the aircraft.
