ATMEGA128-16AU

The ATMEGA128-16AU is an 8-bit AVR microcontroller based on the high-performance, low-power AVR RISC architecture. It features 128KB of in-system self-programmable Flash memory, 4KB EEPROM, and 4KB internal SRAM. The device operates at up to 16 MHz, delivering up to 16 MIPS throughput. It includes 53 general-purpose I/O lines, 32 general-purpose working registers, and a rich set of peripherals: two 8-bit timer/counters with separate prescalers and compare modes, two expanded 16-bit timer/counters, a real-time counter, two USARTs, a byte-oriented two-wire serial interface (I²C), an SPI serial interface, and an 8-channel 10-bit ADC with optional differential input and programmable gain. Additional features include brown-out detection, power-on reset, programmable watchdog timer, and an internal calibrated RC oscillator. The microcontroller supports JTAG interface for boundary-scan and on-chip debug, as well as QTouch capacitive touch sensing. It is supplied in a 64-pin TQFP package with a 14x14 mm body and is surface mountable. The operating voltage range is 4.5V to 5.5V, and it is rated for industrial temperature range from -40°C to +85°C. This microcontroller is suitable for a wide range of embedded applications requiring moderate memory and peripheral integration.
