Microchip AVR® EB Microcontrollers (MCUs)

Featuring a robust and efficient core

Microchip’s AVR EB Microcontroller (MCU) family combines powerful Core Independent Peripherals (CIPs) with the robust and efficient AVR CPU core, making it capable of driving highly accurate systems, optimizing system performance and reducing BOM cost.

With a 12-bit differential Analog-to-Digital Converter (ADC) and high-speed analog comparators, the Microchip AVR EB MCUs can leverage the Event System (EVSYS), allowing for peripherals to interact with each other without CPU intervention. Advanced timer/counter modules make this product family a great fit for a variety of applications including motor control, predictive maintenance, home automation, industrial process control, automotive and Internet of Things (IoT).

The AVR EB family uses enhanced timer/counter modules to enable advanced waveform generation for power and motor drive applications. These MCUs have a Timer/Counter Type E (TCE) and a Timer/Counter Type F (TCF) at their disposal. The TCE is a 16-bit timer with four compare channels that allow it to trigger multiple events at different points and a high-resolution function that increases the resolution of the waveform generated up to eight times.

The TCF is a 24-bit timer/counter that can generate frequency at a high resolution while also running asynchronously from the peripheral clock, allowing for high-speed operation.When used in conjunction with the Waveform Extension (WEX) these MCUs enable extra functions for Timer/Counters in Waveform Generation (WG) modes. It generates complementary waveforms, controls dead-time, pattern generation and fault handling.

Hardware

Microchip features the AVR16EB32 Curiosity Nano board is the best platform for rapid prototyping with the EB Family of MCUs. This USB-powered kit features an on-board programmer/debugger that seamlessly integrates with MPLAB® X, Microchip Studio and IAR Embedded Workbench for AVR® Integrated Development Environments (IDEs). Its small form factor makes it excellent for breadboard soldering, or you can combine it with the Curiosity Nano Base for Click boards™, which features multiple mikroBUS™ sockets so you can easily add sensors, actuators or communications interfaces from Mikroelektronika’s extensive selection of Click boards.
