The Atmel® ATmega128A is an AVR® enhanced RISC-based low-power CMOS 8-bit microcontroller. The ATmega128A is close to 1MIPS per MHz because it can run powerful instructions in a single clock cycle. This lets system designers find the best balance between how much power the device uses and how fast it can process information.
The Atmel AVR core includes a full instruction set and 32 general-purpose working registers. The Arithmetic Logic Unit is connected to all 32 registers (ALU). As a result, a single instruction that executes in a single clock cycle can access two separate registers. The architecture is code-efficient and outperforms CISC microcontrollers in throughput by up to ten times.
The ATmega128A includes Real Time Counter (RTC), four flexible Timer/Counters with compare modes and PWM, a Real Time Counter (RTC), 128Kbytes of Read-While-Write In-System Programmable Flash, 4Kbytes EEPROM, 4Kbytes SRAM, 53 general purpose I/O lines, 32 general purpose working registers, 2 USARTs, and one byte-oriented Two-wire Serial Interface. IEEE std. Power-down mode preserves register values but stops all chip operations until the subsequent interrupt or hardware reset by freezing the oscillator. In Power-save mode, the asynchronous timer operates, allowing the user to maintain a timer base while the device is dormant.
Asynchronous Timer and ADC are the only I/O modules enabled by the ADC Noise Reduction option, which reduces switching noise during ADC conversions. The Crystal/Resonator Oscillator is in “Standby” mode while the gadget is dormant. The machine starts up more quickly and consumes less energy as a result. Running in extended standby is the primary oscillator and asynchronous timer. The device uses high-density nonvolatile memory from Atmel. The on-chip ISP Flash can reprogram the program memory in-system using an SPI serial interface, a conventional nonvolatile memory programmer, or an AVR core running On-chip Boot software.
The boot software can use any interface to download the application program to application Flash memory. Using Boot Flash software while upgrading Application Flash makes genuine read-while-writing work. A powerful microcontroller that may be utilized in various embedded control applications is the Atmel ATmega128A. It comprises an integrated In-System Self-Programmable Flash and an 8-bit RISC CPU. There is a full set of program and system development tools for the ATmega128A AVR. C compilers, macro assemblers, program debuggers/simulators, in-circuit emulators, and evaluation kits are some of these tools.
