ATMEGA1284P-PU Description

Short technical summary and product information.

The ATMEGA1284P-PU is a high-performance, low-power 8-bit AVR microcontroller based on the advanced RISC architecture. It features 128KB of in-system self-programmable Flash memory, 16KB of internal SRAM, and 4KB of EEPROM. The device can achieve up to 20MIPS throughput at 20MHz, with most instructions executing in a single clock cycle.

Key peripherals include two 8-bit and one 16-bit timer/counter with separate prescalers and compare modes, six PWM channels, an 8-channel 10-bit ADC, and an analog comparator. Connectivity options include I²C, SPI, and UART/USART interfaces. The microcontroller also features brown-out detection, power-on reset, and a watchdog timer. It operates from a supply voltage of 1.8V to 5.5V and is specified for the industrial temperature range of -40°C to 85°C.

The device is available in a 40-pin PDIP (plastic dual in-line package) for through-hole mounting, making it suitable for prototyping and applications requiring robust mechanical connections. It supports JTAG debugging and in-system programming via the on-chip boot program.
