描述 Description

The ATmegaET128 is a low-power CMOS 8-bit microcontroller based on the AVR? enhanced RISC architecture.? By executing powerful instructions in a single clock cycle, the ATmegaET128 achieves throughput close to 1 MIPS per MHz., and by combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic chip, the ATmegaET128 is a powerful microcontroller that provides a highly flexible and cost-effective solution for many embedded control applications.? The ATmegaET128 AVR is supported with a full suite of program and system development tools including:? C compilers, macro assemblers, program debugger/simulators, in-circuit emulators, and evaluation kits.
