ATMEGA644P-20AU More Information

ATmega644PA 8-bit AVR® Microcontrollers: Microchip ATmega644PA 8-bit AVR® CMOS Microcontrollers are low-power, and based on the AVR® enhanced RISC architecture. The Atmel ATmega644PA is a powerful 8-bit microcontroller, that offers excellent flexibility and cost effective solution to a wide range of embedded control applications. The ATmega644PA produces throughputs close to 1MIPS per MHz, by using up to 131 powerful instructions in a single clock cycle. Using this process, the designer can optimize the ATmega644PA for power consumption versus processing speed. The 32x8 general-purpose working registers with an extensive instruction set are combined in the Atmel AVR® core. The 32 general-purpose working registers are directly connected to the Arithmetic Logic Unit (ALU). This allows two independent registers to be accessed in a single instruction and executed in one clock cycle to achieve throughputs up to ten times faster than conventional CISC microcontrollers.Learn More

picoPower AVR® MCUs: Microchip AVR® microcontrollers are low-power, high-performance, and can handle demanding 8-bit applications. With a single cycle instruction RISC CPU, innovative picoPower® technology, and a rich feature set, the AVR architecture ensures fast code execution combined with the lowest possible power consumption. With picoPower technology, AVR MCUs feature true 1.8V supply voltage, minimized leakage current, sleeping BOD, ultra-low-power 32kHz crystal oscillator, digital input disable registers, clock gating, and flash sampling.

Ethernet of Everything: Microchip Ethernet of Everything is a quick and easy networking of "things" that can be controlled or connected. Common products that are easily connected and provide intelligent control through the Ethernet of Everything include garage openers, home appliances, HVAC systems, lighting and an unlimited lineup of other products. From the simplest environmental sensor to processing intensive devices, Microchip's 8-bit and 32-bit microcontrollers enable these applications, using lightweight stacks and a broad mix of smart peripherals. These devices work independently of the core and require little to no CPU intervention. Microchip's Ethernet of Everything has development support that helps build upon an established networking foundation. The age of digital building enables Microchip's Ethernet of Everything to provide improved system performance, reduced latency, as well as ease of installation and scaling. This also includes the option to incorporate Power of Ethernet (PoE) for single line power and communications.Learn More
