ATMEGA128A-AU
Microchip TechnologyATMEGA128A-AU is an 8-bit AVR microcontroller from Microchip Technology running at 16 MHz, with 128 KB of in-system programmable Flash, 4 KB of SRAM and 4 KB of EEPROM, and 53 general-purpose I/O lines, operating from 2.7 V to 5.5 V in a TQFP-64 package rated from -40 C to +85 C. It is the largest memory and I/O configuration of the classic megaAVR family, so it gives long-lived industrial, instrumentation and control designs generous room for firmware growth while keeping parameter data in on-chip EEPROM instead of an external memory. Selection advice: the AU suffix identifies the TQFP-64 tray-packed industrial-grade order code; because the same device family is sold in several packages and grades, match the complete ATMEGA128A-AU string against your BOM and confirm the packing format with your assembly process. Parameters verified against Microchip Technology documentation.
