ATMEGA128 in ATmega Family
The ATMEGA128 is a mature, 8-bit RISC microcontroller family originally developed by Atmel and now produced by Microchip Technology. Known for its reliability and extensive I/O capabilities, it features 128KB of in-system programmable flash and a wide operating voltage. It is frequently selected for industrial control systems and legacy embedded platforms requiring a stable architecture with high pin counts and robust peripheral sets, including dual USARTs and an 8-channel, 10-bit ADC.
Variants in This Sub-Family
Variants within the ATMEGA128 sub-family primarily differ by clock frequency ratings, voltage ranges, and package types. The standard ATMEGA128 typically supports up to 16MHz at 4.5V to 5.5V, while the 'L' variants (ATMEGA128L) are optimized for lower voltage operation, typically 2.7V to 5.5V, with a reduced maximum clock speed of 8MHz. Packaging options include 64-lead TQFP and MLF configurations for various assembly requirements.
