RF-STAR Launched a Sub-1 GHz+2.4 G Dual-band Multi-protocol SMD Wireless Module Developed Based on CC1352R

PublishTime： 2021-12-22 Article Source：RF-STAR

CC1352r is a multi protocol sub-1 GHz and 2.4 GHz dual band wireless MCU. Unlike cc1352p, cc1352r has no power amplifier. The CC1352r device has very low active RF and micro controller (MCU) current, sleep current less than 1 μ A and up to 80Kb ram retention capacity protected by parity, which can provide excellent battery life and support long-term operation in energy collection applications relying on small button batteries.

The CC1352r device combines a flexible ultra-low power RF transceiver with a powerful 48 MHz arm ® cortex ® - m4f CPU. Low level RF protocol commands stored in ROM or RAM are processed by a dedicated radio controller (arm ® cortex ® - M0), thus ensuring ultra-low power consumption and excellent flexibility. The sensor controller with fast wake-up and ultra-low power consumption 2MHz mode is specially designed for sampling, caching and processing of analog and digital sensor data, so MCU system can maximize sleep time and reduce working power consumption.

RF-Star has now launched this excellent CC1352R module RF-TI1352B1, which is a sub-1 GHz+2.4 G dual-band multi-protocol SMD wireless module with a small size and IPEX generation antenna base independently developed based on CC1352R. Supports Sub 1-GHz and 2.4 GHz multi-protocols, including Thread, Zigbee, BLE5.0 and TI 15.4-Stack (Sub1-GHz).
