The ATXMEGA16E5-AU is an 8-bit Microcontroller with 32-pin TQFP (Thin Quad Flat Pack) package from Microchip/Atmel. It operates within a wide voltage range of 1.6 to 3.6V and is specified for industrial temperature range (-40°C to +85°C). It is a low-power device with typical maximum power consumption of 1.5mA and can conduct operation at internal clock frequencies up to 32MHz. It has 16KB Flash, 1K SRAM, 128- byte EEPROM and integrated peripherals such as USART, SPI, TWI, USART, I2C, 10-bit A/D converter. The device supports multiple sleep modes with selectable power saving components. It follows AVR 8-bit instruction set architecture and comes with In-System Programmable (ISP) and In-Application Programmable (IAP) flash programming modes. It contains programmable brown-out detection, watchdog and clock tuning functions. It is compatible with various Atmel development tools for easy and cost effective development.
