ATTINY84A-MU Description

Short technical summary and product information.

The ATTINY84A-MU is a high-performance, low-power 8-bit AVR microcontroller from Microchip Technology, part of the ATtiny series. It features 8KB of in-system self-programmable Flash memory, 512 bytes of SRAM, and 512 bytes of EEPROM, providing a balanced memory architecture for embedded applications.

Operating at a maximum speed of 20 MHz and with a supply voltage range of 1.8V to 5.5V, this microcontroller is designed for flexible power management. It includes 12 programmable I/O lines, an 8-channel 10-bit ADC with differential input pairs and programmable gain, and peripherals such as brown-out detection, power-on reset, PWM, a temperature sensor, and a watchdog timer.

The device is housed in a compact 20-WFQFN exposed pad package (20-QFN-EP, 4x4 mm) for surface mount assembly. It supports the Universal Serial Interface (USI) for connectivity and includes an internal oscillator. With an industrial temperature range of -40°C to +85°C, it is suitable for demanding environments.
