ATtiny1627 Product Family
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 16 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.
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.
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 MPLAB® X, Microchip Studio and IAR Embedded Workbench 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.
Tools to Speed Up Your Development
Our intuitive, web-based graphical configuration tools will significantly reduce your development time. Offering an easy-to-use interface, MPLAB Code Configurator (MCC) and Atmel START generate easy-to-use C code to help you get started quickly with your design. MCC is fully integrated into MPLAB X IDE so you can quickly and easily select and configure peripherals for your project. With just a few clicks, the online Atmel START generates a project that can be imported into both MPLAB X and Atmel Studio IDEs and can be easily modified at any time.
Functional Safety Ready for Safety-Critical Applications
The ATtiny1627 family is recommended for safety critical applications targeting both industrial and automotive products (IEC 61508 and ISO 26262). 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® microcontrollers. Documents such as FMEDA reports and safety manuals are available on request. Safety-certified development tools are also available for this product. Please contact your local Microchip sales office or your distributor for more information.
Building Blocks for Real-Time Control and Sensor Applications
The on-chip 12-bit, 375 ksps differential Analog-to-Digital Converter (ADC) features selectable internal voltage references with minimal temperature drift. Use the hardware averaging and oversampling to improve noise suppression and accuracy for analog inputs. Averaging and threshold detection enable the MCU to remain asleep for longer periods, significantly reducing power consumption.
The Programmable Gain Amplifier (PGA) supports up to 16x gain making it possible to retrieve small signals in noisy environments.
The on-board Analog Comparator can be connected to other peripherals through the Event System to trigger autonomous operation in those peripherals, which is ideal for real-time control and closed-loop operations.
