ATTINY44A-MFR Description

Short technical summary and product information.

The ATTINY44A-MFR is an 8-bit AVR microcontroller manufactured by Atmel. It is based on the AVR core and is designed for embedded control applications requiring low power and compact size. The device is supplied in a 20-WFQFN exposed pad package (20-QFN-EP 4x4 mm) for surface mount assembly.

 

The MCU features 4KB of in-system programmable flash memory, 256 bytes of SRAM, and 256 bytes of EEPROM. It operates at speeds up to 20MHz and provides 12 general-purpose I/O pins. Connectivity is supported through a Universal Serial Interface (USI). Integrated peripherals include a brown-out detect/reset, power-on reset, pulse-width modulation (PWM), temperature sensor, and watchdog timer. For analog interfacing, the device includes an 8-channel 10-bit analog-to-digital converter.

 

The operating voltage range is 1.8V to 5.5V, allowing flexible power supply designs. It is specified for an ambient temperature range of -40°C to +125°C, making it suitable for harsh environments. An internal oscillator is available to reduce external component count.

 

The combination of the 10-bit ADC, PWM, and temperature sensor supports sensing and control functions. The small package and low-voltage operation enable compact, low-power designs for portable and embedded applications.
