ATTINY44A-SSNR Description

Short technical summary and product information.

The ATTINY44A-SSNR is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. It features 4KB of in-system self-programmable Flash memory, 256 bytes of SRAM, and 256 bytes of EEPROM. The device operates at a maximum frequency of 20MHz and supports a supply voltage range of 1.8V to 5.5V. With 12 general-purpose I/O lines, it includes an 8-channel 10-bit ADC, internal oscillator, and peripherals such as brown-out detection, power-on reset, PWM, watchdog timer, and temperature sensor. The microcontroller is available in a 14-pin SOIC package (14-SOIC, 0.154" width) for surface mount assembly. It is suitable for a wide range of embedded control applications requiring low power consumption and high performance.
