ATMEGA8A-PU Description

Short technical summary and product information.

The ATMEGA8A-PU is a low-power 8-bit AVR microcontroller based on the AVR RISC architecture. It achieves up to 16 MIPS throughput at 16 MHz, allowing efficient power consumption versus processing speed trade-offs.

 

Memory includes 8KB of self-programmable Flash, 1KB SRAM, and 512 bytes EEPROM with high endurance (10,000 Flash / 100,000 EEPROM write/erase cycles). Peripherals include two 8-bit timers, one 16-bit timer, three PWM channels, a 6-channel 10-bit ADC, USART, SPI, I2C, an analog comparator, and a watchdog timer.

 

The device operates from 2.7V to 5.5V and over -40°C to +85°C temperature range. It is housed in a through-hole 28-pin PDIP package (0.300" width), suitable for prototyping and industrial environments.
