Texas Instruments' CC1352P 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 including the TI 15.4-Stack. The device contains a +20 dBm integrated high-power amplifier with best-in-class efficiency for long-range applications.
The CC1352P device is a member of the SimpleLink MCU platform of cost-effective, ultra-low power, 2.4 GHz and sub-1 GHz RF devices. Ultra-low active RF and MCU currents, in addition to sub-µA sleep current with up to 80 KB of parity protected RAM retention, provide excellent battery lifetime and allow operation on small coin-cell batteries and in energy-harvesting applications.
The CC1352P device combines a flexible, ultra-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 to ensure ultra-low-power and great flexibility. The low power consumption of the MCU does not come at the expense of RF performance thanks to its excellent sensitivity and robustness (selectivity and blocking) performance. The flexible radio in the CC1352P enables concurrent time-multiplexed multi-protocol and multi-band operation through the dynamic multi-protocol manager (DMM) driver.
The CC1352P device is a highly integrated, true single-chip solution that incorporates a complete RF system and an on-chip DC/DC converter. Sensors can be handled in an ultra-low-power manner by a programmable, autonomous ultra-low-power sensor controller CPU with 4 KB of SRAM for program and data. The sensor controller, offers fast wake-up and ultra-low-power 2 MHz mode that is designed for sampling, buffering, and processing analog and digital sensor data to maximize sleep time and to reduce active power.
