ATMEGA1284 in ATmega Family
The ATMEGA1284 is a high-performance, low-power 8-bit microcontroller family based on the Microchip (formerly Atmel) AVR RISC architecture. It serves as a significant memory expansion over the standard ATmega328P, offering 128KB of Flash and a generous 16KB of SRAM. Engineered for applications requiring extensive data buffering or larger software stacks, it maintains the ease of use associated with the AVR ecosystem while providing the resources needed for more complex embedded tasks.
Variants in This Sub-Family
The ATMEGA1284 sub-family includes several variants distinguished primarily by their power consumption and physical packaging. The 'P' suffix, as in the ATMEGA1284P, denotes PicoPower technology, which significantly reduces current draw in sleep modes. Packaging options range from the hobbyist-friendly 40-pin PDIP to space-saving 44-lead TQFP and VQFN surface-mount footprints. Standard variants support up to 20MHz, while certain low-voltage 'V' versions operate at lower frequencies for battery-powered efficiency.
