ATMEGA1284-AU Description

Short technical summary and product information.

The ATMEGA1284-AU is a high-performance, low-power 8-bit AVR microcontroller from Microchip Technology featuring 128KB of self-programmable Flash memory, 16KB SRAM, and 4KB EEPROM. It operates at up to 20MHz providing 20MIPS throughput.

This microcontroller includes a rich set of peripherals such as two 8-bit and one 16-bit timer/counters, PWM channels, an 8-channel 10-bit ADC, and multiple serial communication interfaces (I²C, SPI, UART/USART). It also supports JTAG for boundary-scan and on-chip debug.

The device comes in a 44-pin TQFP package (10x10mm) with 32 general-purpose I/O pins. It operates over a wide voltage range of 1.8V to 5.5V and is specified for -40°C to +85°C temperature range. The internal oscillator simplifies design while the Brown-out Detect, Power-on Reset, and Watchdog Timer enhance system reliability.
