The ATTINY44A-MMH is a low-power, high-performance 8-bit AVR microcontroller from Microchip Technology. It features 4KB of in-system self-programmable Flash memory, 256 bytes of SRAM, and 256 bytes of EEPROM with high endurance ratings of 10,000 and 100,000 write/erase cycles respectively. Data retention is rated at 20 years at 85°C and 100 years at 25°C.
Operating from 1.8V to 5.5V, this MCU can run at up to 20 MHz at higher voltages. It includes a 10-bit ADC with 8 single-ended channels, a Universal Serial Interface (USI), two timer/counters with PWM, an on-chip temperature sensor, and a watchdog timer. Power consumption is minimal with 210 µA typical active current at 1.8V and 1 MHz, and only 0.1 µA in power-down mode.
The device is housed in a 20-VFQFN exposed pad package (20-VQFN 3x3mm) for surface mount assembly. It offers 12 I/O pins and supports internal oscillators, brown-out detection, and power-on reset. This microcontroller is suitable for a wide range of embedded control applications requiring low power and a compact footprint.
The operating voltage range is 1.8V to 5.5V.
It comes in a 20-VFQFN Exposed Pad package, also known as 20-VQFN (3x3mm).
The operating temperature range is -40°C to 85°C.
The RoHS status is listed as RoHS3 Compliant, but this is unverified and should be confirmed.
It has 4KB of Flash program memory.
The maximum clock speed is 20 MHz at 4.5V-5.5V, 10 MHz at 2.7V-5.5V, and 4 MHz at 1.8V-5.5V.
Yes, it has a 10-bit ADC with 8 single-ended channels.
