1. Gener
al Description
The GTI-ATM2022-X module is an extreme low-power Bluetooth® 5 system-on-a-chip (SoC) solution. This innovative
module design is based on the extremely low power Atmosic M2 Series Bluetooth wireless platform. The GTI-
ATM2022-X design incorporates several innovative features that have a dramatic impact on extending the battery life
of edge-of-network connected IoT products. This Bluetooth SIG certified Bluetooth Low Energy SoC integrates a
Bluetooth 5.0 compliant radio with an ARM® Cortex® M0 application processor, 128 KB, 512 KB or 1MB embedded
Flash, 128 KB Random Access Memory (RAM), 256 KB Read-Only Memory (ROM), 4 KB One-Time-Programmable
(OTP) memory, and state-of-the-art power management.
The extremely low power ATM2 series SoC with 900uA active Rx and 2.4 mA active Tx full system power and has
been designed to extend battery life for the Internet-of-Things (IoT) applications. Support for low duty cycle operation
allows systems to run for significantly longer time periods without battery replacement
