GlobalScale launches Energy Harvesting Bluetooth LE 5.3 module

2 mins read

GlobalScale, an IoT solutions provider, and Atmosic Technologies, a specialist in extreme-low-power wireless communication platforms, are making available a new Bluetooth 5.3 module with integrated energy harvesting capabilities.

GlobalScale has chosen the ATM3330e, which is part of Atmosic’s ATM33/e series of SoCs, as the core silicon used in the newest member of the RistrettoBin family of Bluetooth LE modules.

The module, the GTI-ATM3330e, builds on the success of GlobalScale's earlier Atmosic-based ATM2 module. It has a more powerful Arm Cortex-M33F microcontroller than its predecessor, with additional RAM (128KB) and support for the Bluetooth 5.3 standard and energy harvesting.

The module supports four harvesting methods: photovoltaic (light), motion, thermal, and radio frequency (RF). The integrated power management unit is designed to source energy primarily from harvested sources and save excess harvested energy to any storage element implemented into a customer design. The module supports several energy storage configurations to extend the life of standard batteries or work with a rechargeable battery. The module can even allow devices to operate battery-free with capacitor storage.

“With its high levels of integration and energy harvesting functionality, the ATM33-based module enables GlobalScale’s customers to make products that use a single battery for the life of their product,” said Bryan Cheng, VP for Sales & Marketing at GlobalScale Technologies. “Atmosic’s energy harvesting technology also makes it possible for devices to operate without any battery at all.”

Key features of the ATM3330e module:

  • Bluetooth Low-Energy 5.3 compliant
  • 64 MHz Arm Cortex-M33F MCU
  • 64 KB ROM, 128 KB RAM, 512 KB NVM
  • Wide 1.1 – 4.2v input voltage support
  • Supports RF, photovoltaic, thermal, mechanical, and other energy harvesting sources
  • Support external energy storage interface supports a variety of storage options
  • Support I2C (2), I2S, SPI (2), UART (2), PWM (8), 31 GPIOs
  • Supports quad SPI
  • Supports 11-bit application ADC, 4 external, 5 internal channels, up to 2 Msps
  • Supports two mono or one stereo digital microphone input (PDM)
  • Support 8 x 20 keyboard matrix controller (KSM)
  • Supports quadrature decoder (QDEC)
  • Supports SWD for interactive debugging

“With the introduction of fully certified modules based on the ATM33 series SoC, sustainability is a real and viable option for IoT developers of all applications and project volumes,” said Dylan Ko, Director of Product Marketing at Atmosic Technologies. “Partners such as GlobalScale bring fantastic time-to-market and value-add through their custom design service capabilities, which in turn help reduce the ever-increasing toxic side effects of battery use in the IoT.”

To support customers developing their applications with the GTIM333E module, GlobalScale offers a full-featured development kit (GTI-ATM3330E-DEV) that provides a host of peripherals including an LTE-M1/GNSS module, temperature sensor, and a 3-axis accelerometer for developers creating a broad range of IoT projects.
