The CC2620 device is a wireless MCU targeting ZigBee® RF4CE remote control applications, both controller and target node. The device is a member of the CC26xx family of cost-effective, ultralow power, 2.4-GHz RF devices. Very low active RF and MCU current and low-power mode current consumption provide excellent battery lifetime and allow for operation on small coin cell batteries and in energy-harvesting applications. The CC2620 device contains a 32-bit ARM Cortex-M3 processor that runs at 48 MHz as the main processor and a rich peripheral feature set that includes a unique ultralow power sensor controller. This sensor controller is ideal for interfacing external sensors and for collecting analog and digital data autonomously while the rest of the system is in sleep mode. Thus, the CC2620 device is ideal for ZigBee RF4CE remote controls with features like voice, motion, RF-IR hybrid remotes, and qwerty keyboards and STB/target nodes with capacitive touch. The IEEE 802.15.4 MAC is embedded into ROM and runs partly on an ARM Cortex-M0 processor. This architecture improves overall system performance and power consumption and frees up flash memory for the application. Software stack support for this device includes: ZigBee RF4CE stack (RemoTI) which is available free of charge from www.ti.com.
