Mesh Networking Module CTL3212

1. General Description

The Module (CTL3212) is a fully-integrated, pre-certified module, enabling rapid development of wireless mesh networking solutions.

Based on the Silicon Labs EFR32™ Mighty Gecko SoC, the CTL3212 combines an energyefficient, multi-protocol wireless SoC with a proven RF/antenna design and industry leading

wireless software stacks. This integration accelerates time-to-market and saves months of engineering effort and development costs.

The size of CTL3212 is 22x13x2.6mm.It integrated a 2.4GHz, IEEE 802.15.4-2003 compliant transceiver with a 32-bit network processor (ARM Cortex-M4 Processor) .It contains embedded FLASH and integrated RAM for program and data storage.

2. Applications

3. Features

 Complete ZigBee-ready module with integrated PCB antenna  Integrated IEEE 802.15.4 PHY and MAC layer  SPI /UART interface for communication and controlled by the Host using the EmberZNet Serial

Protocol (EZSP)

 On Board oscillator  High performance direct sequence spread spectrum (DSSS-OQPSK) RF transceiver  16 channels in the 2.4 GHz ISM band  On-chip regulator for 1.8-3.8V operation.  Three deep low power modes  32-bit ARM® Cortex™-M4 processor  512KB FLASH ROM and 64KB RAM(EFR32 internal memory)  +19dBm /+10dBm Max. transmission power  -99 dBm sensitivity (typ)  Small footprint: 22x13x2.6mm  Extremely low Deep Sleep Current.
