ATmega128L-8AU

Product Summary

The ATmega128L-8AU is an 8-bit Microcontroller. The ATmega128L-8AU is manufactured using Atmel’s high-density nonvolatile memory technology. The Onchip ISP Flash allows the program memory to be reprogrammed in-system through an SPI serial interface, by a conventional nonvolatile memory programmer, or by an On-chip Boot program running on the AVR core. The boot program can use any interface to download the application program in the application Flash memory. Software in the Boot Flash section will continue to run while the Application Flash section is updated, providing true Read-While-Write operation. By combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic chip, The ATmega128L-8AU is a powerful microcontroller that provides a highly flexible and cost effective solution to many embedded control applications.The ATmega128L-8AU 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.
