The CC1312R device is a
Sub-1 GHz wireless MCU targeting Wireless M-Bus, IEEE
802.15.4g, IPv6-enabled smart objects (6LoWPAN),
Zigbee®, KNX RF,
Wi-SUN®, and proprietary
CC1312R 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 CC1312R 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 CC1312R device does not come at
the expense of RF performance; the CC1312R device has excellent sensitivity
and robustness (selectivity and blocking) performance.
The CC1312R 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 CC1312R 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. For more information, visit
