Visão Geral
Description
- 128KB Flash, 8KB SRAM, and 2KB EEPROM.
- 32MHz max clock speed with efficient pipelined RISC architecture.
- USB 2.0 Full-Speed support with an on-chip transceiver.
- DMA controller for efficient data transfer.
- Advanced peripherals: 12-bit ADC, DAC, USART, SPI, I²C, and timers.
- 64-pin QFN (MH) package, suitable for compact designs.
Ideal for embedded applications requiring USB connectivity, real-time control, or low-power operation (1.6–3.6V range). Its robust feature set makes it suitable for industrial, consumer, and communication systems.
Equivalent
1. ATXMEGA128A3U-AU (TQFP package, same specs).
2. ATXMEGA128A4U-MH (similar, more flash).
3. ATXMEGA128A1U-MH (fewer peripherals).
4. SAM D21 (ARM-based, from Microchip).
5. STM32F0/F3 (ARM Cortex-M, STMicroelectronics).
Check pin compatibility and peripherals for exact replacements.
