Microchip Technology, Inc. Microcontrollers ATMEGA8U2-AU

The ATmega8U2-AU is an 8-bit microcontroller from Quarktwin Technology Ltd. that operates at a maximum frequency of 16 MHz and is designed for low power consumption. It features an advanced RISC architecture that allows for efficient execution of instructions, achieving up to 16 MIPS throughput. The microcontroller includes 8 KB of in-system self-programmable Flash memory, 512 bytes of EEPROM, and 512 bytes of SRAM, with a data retention of 20 years at 85¬8C and 100 years at 25¬8C. This device supports USB 2.0 full-speed device functionality, allowing for data transfer rates of 12 Mbit/s, and includes a dedicated 176 bytes of USB DPRAM for endpoint memory allocation. It has multiple programmable endpoints and supports various transfer types including bulk, interrupt, and isochronous transfers. The ATmega8U2-AU also features several peripheral components such as timers, a USART with SPI master mode, and an on-chip analog comparator. The microcontroller operates within a voltage range of 2.7V to 5.5V and is suitable for industrial applications with an operating temperature range of -40¬8C to +85¬8C. It is available in two package types: QFN32 and TQFP32, making it versatile for different design requirements.
