ATTINY84A-SSUR

The ATTINY84A-SSUR is an 8-bit AVR microcontroller from Microchip Technology, part of the ATtiny84A family. It features a high-performance AVR RISC architecture with 120 instructions, most executed in a single clock cycle. The device includes 8KB of in-system self-programmable Flash memory, 512B of SRAM, and 512B of EEPROM with high endurance (10,000 write/erase cycles for Flash, 100,000 for EEPROM). It operates at speeds up to 20MHz and supports a wide supply voltage range of 1.8V to 5.5V.

Key peripherals include an 8-channel 10-bit ADC, two timer/counters with PWM, a universal serial interface (USI), brown-out detection, power-on reset, and an on-chip temperature sensor. The microcontroller also features debugWIRE for on-chip debugging and SPI for in-system programming. With 12 programmable I/O lines, it is suitable for a variety of embedded control applications.

The device is designed for industrial temperature ranges from -40°C to +85°C. It is available in a 14-pin SOIC package (0.154" width) for surface mount assembly. The internal calibrated oscillator eliminates the need for external clock components in many applications. Low power consumption modes (Idle, ADC Noise Reduction, Standby, Power-down) make it suitable for battery-powered designs.
