The CC1352R device is a multiprotocol Sub-1 and 2.4-GHz wireless MCU targeting Wireless M-Bus, IEEE 802.15.4g, IPv6-enabled smart objects (6LoWPAN), Thread, Zigbee®, KNX RF, Wi-SUN®, Bluetooth® 5 low energy, and proprietary systems.
CC1352R is a member of the CC26xx and CC13xx family of cost-effective, ultra-low power, 2.4-GHz and Sub-1 GHz RF devices. Very low active RF and microcontroller (MCU) current, in addition to sub-µA sleep current with up to 80KB of RAM retention, provide excellent battery lifetime and allow operation on small coin-cell batteries and in energy-harvesting applications.
The CC1352R device combines a flexible, very low-power RF transceiver with a powerful 48-MHz Arm® Cortex®-M4F CPU in a platform supporting multiple physical layers and RF standards. A dedicated Radio Controller (Arm® Cortex®-M0) handles low-level RF protocol commands that are stored in ROM or RAM, thus ensuring ultra-low power and great flexibility. The low power consumption of the CC1352R device does not come at the expense of RF performance; the CC1352R device has excellent sensitivity and robustness (selectivity and blocking) performance.
The CC1352R device is a highly integrated, true single-chip solution incorporating a complete RF system and an on-chip DC/DC converter.
Sensors can be handled in a very low-power manner by a programmable, autonomous ultra-low power Sensor Controller CPU with 4KB of SRAM for program and data. The Sensor Controller, with its fast wake-up and ultra-low-power 2-MHz mode is designed for sampling, buffering, and processing both analog and digital sensor data; thus the MCU system can maximize sleep time and reduce active power.
The CC1352R device is part of the SimpleLink™ microcontroller (MCU) platform, which consists of Wi-Fi®, Bluetooth® low energy, Thread, Zigbee, Sub-1 GHz MCUs, and host MCUs, which all share a common, easy-to-use development environment with a single core software development kit (SDK) and rich tool set. A one-time integration of the SimpleLink platform enables you to add any combination of the portfolio’s devices into your design, allowing 100 percent code reuse when your design requirements change.

With the trend of better lighting homogeneity, high-current LEDs are often used in automotive front and rear lamps with lighting diffusers and light-guides. Meanwhile, in order to meet strict EMC and reliability requirements, linear LED drivers are popular in automotive applications. However, it is a challenge to deliver high current for linear LED drivers with integrated power transistors. The TPS92830-Q1 device is an advanced automotive-grade high-side constant-current linear LED controller for delivering high current using external N-channel MOSFETs. The device has a full set of features for automotive applications and is compatible with a wide selection of N-channel MOSFETs.
Each channel of the TPS92830-Q1 device sets the channel current independently by the sense-resistor value. An internal precision constant-current regulation loop senses the channel current by the voltage across the sense resistor and controls the gate voltage of the N-channel MOSFET accordingly. The device also integrates a two-stage charge pump for low-dropout operation. The charge-pump voltage is high enough to support a wide selection of N-channel MOSFETs. PWM dimming allows multiple
sources for flexibility—internal PWM generator, external PWM inputs, or power supply dimming. Various diagnostics and protection features specially designed for automotive applications help improve system robustness and ease of use. A one-fails–all-fail fault bus supports TPS92830-Q1 operation together with the TPS92630-Q1, TPS92638-Q1, and TPS9261x-Q1 family to fulfill various fault-handling requirements.
