ATTINY84A-SSU

The ATTINY84A-SSU is an 8-bit AVR microcontroller from Microchip Technology, part of the ATtiny84A family. It features a high-performance, low-power AVR RISC architecture with 120 instructions, most executed in a single clock cycle. The device integrates 8KB of in-system self-programmable flash memory, 512 bytes of SRAM, and 512 bytes of EEPROM with high endurance (10,000 write/erase cycles for flash and 100,000 for EEPROM).

Key peripheral features include a 10-bit ADC with 8 single-ended channels and 12 differential pairs with programmable gain, two timer/counters with PWM, an on-chip analog comparator, a universal serial interface (USI), a watchdog timer, and an on-chip temperature sensor. The microcontroller supports brown-out detection, power-on reset, and multiple low-power sleep modes including Idle, ADC Noise Reduction, Standby, and Power-down.

The operating voltage range is 1.8V to 5.5V, and the maximum clock frequency is 20MHz at 4.5V-5.5V. The industrial temperature range spans -40°C to +85°C. The device is available in a 14-pin SOIC package with 12 programmable I/O lines and surface-mount mounting style.
