ATMEL 8-Bit AVR Microcontroller, 16K Flash, 44-Pin TQFP

The ATMEL 8-Bit AVR Microcontroller is a high-performance picoPower RISC-based device that combines 16kB ISP flash memory with read-while-write capabilities, 512B EEPROM, and 1kB SRAM. By executing powerful instructions in a single clock cycle, this microcontroller achieves throughputs approaching 1 MIPS per MHz, effectively balancing power consumption and processing speed.

This advanced RISC architecture features an on-chip 2-cycle multiplier and high-endurance, non-volatile memory segments. It includes 32 general purpose I/O lines, 32 general purpose working registers, a real time counter, and three flexible timer/counters with compare modes and PWM. Communication is supported through two USARTs, a byte-oriented 2-wire serial interface, and an SPI serial port.

Equipped with an 8-channel 10-bit A/D converter with an optional differential input stage and programmable gain, this device is highly versatile. It also features a programmable watchdog timer with an internal oscillator, and a JTAG (IEEE 1149.1 compliant) test interface for on-chip debugging and programming. QTouch® library support enables capacitive touch buttons, sliders, and wheels.

Designed for efficiency, it offers six software selectable power saving modes: Idle, ADC noise reduction, power-save, power-down, standby, and extended standby. The device operates between 1.8V and 5.5V, with power-on reset (POR) and programmable brown-out detection. The microcontroller weighs 2.188 grams and has dimensions of 43 mm in height, 33 mm in width, and 15 mm in depth.
