ATMEGA168A-AU Description

Short technical summary and product information.

The ATMEGA168A-AU is a high-performance, low-power 8-bit AVR microcontroller from Atmel. It features 16KB of in-system self-programmable Flash memory, 1KB SRAM, and 512 bytes EEPROM, with endurance of 10,000 write/erase cycles for Flash and 100,000 for EEPROM. Data retention is rated at 20 years at 85°C and 100 years at 25°C.

 

The device operates over a supply voltage range of 1.8V to 5.5V and can run at up to 20MHz, delivering up to 20 MIPS throughput. It includes 23 general-purpose I/O lines, an 8-channel 10-bit ADC, and peripherals such as two 8-bit timers, one 16-bit timer, PWM channels, and a real-time counter. Connectivity options include I²C, SPI, and UART/USART interfaces.

 

The microcontroller is available in a 32-TQFP surface-mount package with dimensions of 7x7mm. It supports an internal oscillator and includes features like brown-out detection, power-on reset, and watchdog timer. The operating temperature range is -40°C to 85°C.
