In 2016, Atmel was acquired by Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors. The company was a leading provider of microcontrollers, touch solutions, and other semiconductor products for various applications in the consumer, industrial, and automotive markets.Ītmel's products were known for their small form factor, low power consumption, and high performance. 0 - 8MHz 2.7V - 5.5V, 0 - 16MHz 4.5V - 5.5VĨ-bit Microcontroller with 64K/128K/256K Bytes In-System Programmable FlashĨ-bit Atmel Microcontroller with 64K/128K/256K Bytes In-System Programmable FlashĨ-bit Atmel Microcontroller with 64K 128K 256K Bytes In-System Programmable FlashĨ-bit Microcontroller with 16K Bytes In-System Programmable FlashĨ-bit Microcontroller with 4K Bytes In-System Programmable FlashĪtmel Corporation was an American semiconductor company that was founded in 1984.– Six Sleep Modes: Idle, ADC Noise Reduction, Power-save, Power-down, Standby, and Extended Standby – External and Internal Interrupt Sources – Power-on Reset and Programmable Brown-out Detection – Programmable Watchdog Timer with Separate On-chip Oscillator – Six/Twelve PWM Channels with Programmable Resolution from 2 to 16 Bits (ATmega1281/2561, ATmega640/1280/2560) – Real Time Counter with Separate Oscillator – Four 16-bit Timer/Counter with Separate Prescaler, Compare- and Capture Mode – Two 8-bit Timer/Counters with Separate Prescaler and Compare Mode – Programming of Flash, EEPROM, Fuses, and Lock Bits through the JTAG Interface – Boundary-scan Capabilities According to the JTAG Standard – Capacitive touch buttons, sliders and wheels Endurance: Up to 64Kbytes Optional External Memory Space.In-System Programming by On-chip Boot Program.– Optional Boot Code Section with Independent Lock Bits – Data retention: 20 years at 85C/ 100 years at 25C – 64K/128K/256KBytes of In-System Self-Programmable Flash High Endurance Non-volatile Memory Segments.– 32 × 8 General Purpose Working Registers – 135 Powerful Instructions – Most Single Clock Cycle Execution High Performance, Low Power Atmel® AVR® 8-Bit Microcontroller.By executing powerful instructions in a single cloc k cycle, the ATmega640/1280/1281/2560/2561 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. The ATmega640/1280/1281/2560/2561 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture.
