The ATXMEGA256D3-AUR is a cutting-edge microcontroller unit (MCU) from Microchip Technology, renowned for its high performance and low power consumption. This 8/16-bit MCU is built on the innovative AVR® XMEGA® D3 family, designed to meet the needs of sophisticated and power-sensitive applications in the industrial, consumer, automotive, and communication markets.
With a maximum CPU frequency of 32MHz, the ATXMEGA256D3-AUR provides a powerful blend of speed and efficiency. It boasts a substantial 256KB of in-system self-programmable flash, along with 16KB of SRAM and 4KB of EEPROM, ensuring ample space for complex applications and data storage. The device operates at a voltage range of 1.6V to 3.6V, which enables flexible power management and contributes to its energy-efficient operation.
This MCU features an array of integrated peripherals, including eight-channel event system, four 16-bit timers/counters with capture, compare, and PWM capability, two USARTs, two Two-Wire Interfaces (TWIs), two Serial Peripheral Interfaces (SPIs), and 16-channel, 12-bit analog-to-digital converters (ADCs) with optional differential input and programmable gain. Additionally, the ATXMEGA256D3-AUR has a 2-channel, 12-bit digital-to-analog converter (DAC), and analog comparators with a window mode function, broadening its application potential.
The device supports a full-speed USB device and embedded host, which is a testament to its connectivity capabilities. The USB interface underlines the MCU's readiness for modern communication requirements. Safety and reliability are also prioritized, as evidenced by the inclusion of a power-on reset, programmable brown-out detection, and an internal temperature sensor.
The ATXMEGA256D3-AUR is available in a 64-pin TQFP (Thin Quad Flat Package) and is characterized for operation from -40°C to 85°C, making it suitable for use in harsh environments. Its robust feature set, combined with extensive interrupt capabilities and low power options such as power-down, standby, and extended standby modes, make the ATXMEGA256D3-AUR an excellent choice for designers looking to optimize both performance and power efficiency in their next project.
