What the CC1312R does
The CC1312R is a multiprotocol Sub-1 GHz wireless microcontroller supporting IEEE 802.15.4g, 6LoWPAN, and MIOTY. It features a 48-MHz Arm Cortex-M4F processor, 352KB of flash memory, and an ultra-low power sensor controller. The device operates on a 1.8 V to 3.8 V supply with active mode RX current of 5.8 mA at 868 MHz and a maximum transmit power of +14 dBm. Standby current drops to 0.85 µA with full RAM retention. It supports industrial temperature grades up to 105°C. Typically used in smart meters, building automation, medical devices, and grid communications, the CC1312R enables long-range wireless sensor networks and connected peripherals with advanced cryptographic acceleration and flexible protocol stacks.
