ATXMEGA16E5-M4UR – ATMEL

The ATXMEGA16E5-M4UR is a low-power, high-performance 8/16-bit microcontroller based on the AVR enhanced RISC architecture. Fabricated on a low-power process, it features 16KB of in-system self-programmable Flash memory, 2KB of SRAM, and a 512-byte EEPROM. The device operates at a maximum frequency of 32MHz and is supplied in a 32-pin UQFN (Ultra Quad Flat No-leads) package, providing a small footprint suitable for space-constrained applications. Peripheral features include a 12-bit ADC, multiple timers/counters with PWM capabilities, USART, SPI, and I2C interfaces. The M4UR variant indicates a specific temperature range and packaging configuration, typically for industrial applications. The device supports a wide voltage range and incorporates power-saving modes to minimize power consumption in battery-powered or energy-harvesting systems.
