Microcontrollers Overview

The EFM32TG11B320F128GQ48-AR is a Silicon Labs ARM Cortex-M0+ microcontroller featuring 128 kB flash, 32 kB RAM, and a 48 MHz clock speed. It operates on a single 1.8 V to 3.8 V supply without an integrated DC-DC converter. The device includes a CAN bus controller, up to 37 GPIOs, and supports -40 °C to +85 °C temperature ranges. It utilizes a QFP48 package and offers ultra-low power modes with 37 µA/MHz active current.

Microcontrollers Feature Summary

Integrated CAN bus controller supporting version 2.0A and 2.0B protocols for reliable communication.
Robust capacitive sensing technology enabling wake-on-touch functionality for user interfaces.
Hardware cryptographic engine providing AES, ECC, SHA, and True Random Number Generator support.
Low energy analog peripherals including ADC, DAC, operational amplifiers, and segment LCD drivers.

Microcontrollers Applications

Smart energy meters
Industrial and factory automation systems
Home automation and security devices

Microcontrollers Procurement Notes

Verify the specific ordering suffix AR indicates tape and reel packaging configuration. Confirm the absence of the DC-DC converter in the B320 feature set matches system power requirements. Ensure the QFP48 package dimensions align with PCB layout constraints. Validate the -40 to +85 °C temperature grade against environmental operating conditions.

Microcontrollers Selection Notes

Select this variant when a CAN interface is required but an integrated DC-DC converter is unnecessary or externally managed. The QFP48 package provides a balance between pin count and footprint size. Consider the 128 kB flash capacity for application firmware complexity. Verify that the 37 available GPIOs meet the peripheral connection needs.

Microcontrollers Part Context

This component belongs to the EFM32 Tiny Gecko Series 1 family, designed for energy-efficient IoT applications. It builds upon previous generations by adding CAN bus capabilities and enhanced security features while maintaining ultra-low power consumption profiles suitable for battery-operated devices.
