ATMEGA128A in ATmega Family
The ATMEGA128A is a high-performance, low-power 8-bit microcontroller family based on the Microchip (formerly Atmel) AVR enhanced RISC architecture. Known for its 128KB of programmable flash memory and 4KB of EEPROM, it executes powerful instructions in a single clock cycle. This allows the device to achieve throughputs approaching 1 MIPS per MHz, effectively balancing power consumption and processing speed for engineers building robust, legacy-compatible embedded systems and industrial control units.
Variants in This Sub-Family
Variants within the ATMEGA128A sub-family primarily differ in package type, including TQFP and MLF footprints, and industrial temperature grading. While the core 16MHz performance and 128KB flash remain consistent across the sub-family, specific order codes like the ATMEGA128A-ANR indicate specialized packaging options such as tape-and-reel for automated assembly and 'Green' environmental compliance standards for modern RoHS manufacturing requirements.
