Microchip ATtiny3217 Product Family

Demonstrating Microchip’s commitment to supporting the strong legacy of the AVR® family of 8-bit microcontrollers (MCUs), this tinyAVR® family expands the performance of the latest generation of AVR MCUs. These devices incorporate several features including Core Independent Peripherals, a Peripheral Touch Controller (PTC) and a Peripheral Event System. These devices are also supported by Atmel START, an intuitive, online graphical configuration tool for embedded projects that allows you to configure drivers and software for your device.

tinyAVR devices offer an unrivalled combination of miniaturization, processing power, analog performance and system-level integration. The tinyAVR MCU is the most compact, feature-rich device in the AVR family.

Event System

The Event System allows peripherals to communicate directly with each other without involving the CPU or bus resources. The Event System is network independent of the traditional data bus paths. This means different triggers at the peripheral level can result in an event, such as a timer tick triggering a reaction in another peripheral. The Event System has six independent channels and offers a fixed latency of two cycles. Since there is no jitter, it is 100% deterministic method and a perfect fit for real-time applications. No events are lost, and they are handled at a peripheral level in two cycles, even if the CPU is performing a non-maskable interrupt.
