Intelligent, Fast and Accurate Analog

The ATtiny1627 family of AVR® microcontrollers (MCUs) is equipped with high-speed integrated analog, hardware-based Core Independent Peripherals (CIPs) and low-power performance for efficient real-time control and sensor node applications. For design flexibility and to optimize your board layout, this family of 4 KB to 32 KB Flash devices is available in SOIC, SSOP and VQFN packages ranging from 14 to 24 pins. These tinyAVR® MCUs are well suited for a wide range of industrial, consumer, appliance, automotive, sensor node and other applications. If your design is a closed-loop control system, the ATtiny1607 family is a great option. 

Enabling Reliable Sensor Interfaces in Harsh Environments


Designers of reliable sensor end node applications require an MCU that can quickly and accurately measure and convert signals in harsh environments while also using power efficiently. Featuring a 12-bit differential Analog-to-Digital Converter (ADC) and a Programmable Gain Amplifier (PGA) with up to 16x gain, the ATtiny1627 family enables measurement of smaller amplitude signals, reclaims signals from noisy environments and performs fast conversion of the signals.

The accurate and temperature-stable internal 20 MHz RC oscillator, Configurable Custom Logic (CCL), Event System and Core Independent Peripherals significantly reduce the need for external components. The small 3 × 3 mm 20-pin VQFN package option further reduces the PCB footprint, enabling you to create extremely compact and cost-efficient designs.

Getting Started


Take Your Idea from Concept to Prototype


The ATtiny1627 Curiosity Nano board is the ideal platform for rapid prototyping with these tinyAVR MCUs. This USB-powered kit features an on-board programmer/debugger that seamlessly integrates with the MPLAB® X Integrated Development Environments (IDE). 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.

Functional Safety Ready for Safety-Critical Applications


Our ATtiny3227 family for safety-critical applications targets both industrial and automotive products. We also offer the MPLAB XC8 Functional Safety Compiler License, which is a TÜV SÜD-certified compiler package that supports 8-bit PIC® and AVR MCUs. Our ATtiny3227 ISO 26262 and IEC 61508 functional safety packages come with documents such as FMEDA reports and safety manuals.
