ATMEGA8-16AU

The ATmega8-16AU is a high-performance 8-bit AVR microcontroller from Microchip Technology based on the AVR enhanced RISC architecture. It executes 130 powerful instructions in a single clock cycle, achieving up to 16 MIPS throughput at 16 MHz. The device features 8 KB of in-system self-programmable Flash memory, 1 KB of internal SRAM, and 512 bytes of EEPROM with high endurance (10,000 Flash write/erase cycles and 100,000 EEPROM cycles). Data retention is rated at 20 years at 85°C and 100 years at 25°C.

Peripheral features include two 8-bit timer/counters with separate prescaler and compare mode, one 16-bit timer/counter with capture mode, three PWM channels, an 8-channel 10-bit ADC, a byte-oriented two-wire serial interface (I2C), a programmable serial USART, a master/slave SPI interface, a programmable watchdog timer, and an on-chip analog comparator. Special microcontroller features include power-on reset, programmable brown-out detection, an internal calibrated RC oscillator, and five sleep modes (Idle, ADC Noise Reduction, Power-save, Power-down, and Standby).

The ATmega8-16AU operates from a supply voltage of 4.5V to 5.5V and is specified over the industrial temperature range of -40°C to 85°C. Typical power consumption at 4 MHz and 3V is 3.6 mA in active mode, 1.0 mA in idle mode, and 0.5 µA in power-down mode. The device is packaged in a 32-lead TQFP (7x7 mm) for surface mount assembly.
