ATMEGA128-16AUR

The ATMEGA128-16AUR is an 8-bit AVR microcontroller from Microchip Technology based on the high-performance AVR RISC architecture. It features 128KB of in-system self-programmable Flash memory, 4KB SRAM, and 4KB EEPROM, with endurance of 10,000 write/erase cycles for Flash and 100,000 for EEPROM. The device operates at a maximum clock frequency of 16MHz, delivering up to 16 MIPS throughput.

On-chip peripherals include two 8-bit and two 16-bit timer/counters with separate prescalers, an 8-channel 10-bit ADC, dual programmable USARTs, a master/slave SPI interface, and a byte-oriented two-wire serial interface (I2C). It also provides up to 53 general-purpose I/O pins, a programmable watchdog timer, an on-chip analog comparator, and support for JTAG debugging and boundary-scan. The microcontroller includes a brown-out detection circuit, power-on reset, and an internal calibrated RC oscillator.

The device is supplied in a 64-TQFP (14x14mm) surface-mount package and operates over a supply voltage range of 4.5V to 5.5V and a temperature range of -40°C to 85°C. It is suitable for a wide range of embedded control applications including industrial automation, automotive systems, and IoT devices.
