The Microchip Technology ATMEGA640-16AUR is an 8-bit AVR microcontroller. It operates at a speed of 16MHz, with a 64KB Flash memory for storing programs and data. The device also comes with 4KB of EEPROM and 8KB of RAM. It has 100 pins in a TQFP (Thin Quad Flat Package) 14x14mm package, providing 86 general - purpose I/O lines. The operating voltage range is from 2.7V to 5.5V, and it can work in a temperature range of - 40°C to +85°C.
ATMEGA640-16AUR Features
This chip features an advanced RISC architecture, which allows it to execute powerful instructions in a single clock cycle, achieving a throughput of 16 MIPS at 16MHz. It has high - endurance non - volatile memory segments. There are six flexible timer/counters with compare modes and PWM (Pulse Width Modulation) capabilities. It supports multiple communication interfaces such as I²C, SPI, UART/USART, and also has a JTAG (IEEE standard 1149.1 compliant) interface for on - chip debugging. Additionally, it offers power - on reset and programmable brown - out detection, an internal calibrated oscillator, as well as external and internal interrupt sources. It supports various sleep modes like idle, adc noise reduction, power - save, power - down, standby and extended standby, which helps in achieving ultra - low power consumption, for example, only 0.1 μA at 1.8V in power - down mode.
ATMEGA640-16AUR Applications
Due to its rich features and capabilities, the ATMEGA640-16AUR can be widely used in various applications.
