Microchip’s ATTINY1627 family of AVR microcontrollers (MCUs) combines integrated, high-speed analog, hardware-based core independent peripherals (CIPs), and low-power performance for efficient real-time control and sensor node applications. For design flexibility and board layout optimization, this family of 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 space-constrained applications including industrial, consumer, appliance, automotive, and sensor node applications.
