ATMEGA128 datasheet pdf download.

The ATmega128 is a low-power 8-bit microprocessor based on the AVR architecture, which has been improved to make it more suitable for use in small devices.

By executing strong instructions in a single clock cycle, the ATmega128 can achieve throughputs close to 1 MIPS per MHz.

This allows the system designer to balance power consumption and processing performance.

The design produced by using a CISC microcontroller is faster and more code-efficient than traditional microcontroller designs. The AVR microcontroller has an advanced RISC architecture, 133 powerful instructions, and 32 × 8 general-purpose working registers.

It also has peripheral control registers, which means that it can handle a lot of complex tasks with ease. This chip offers non-volatile program and data memories with a maximum capacity of 128 KB.

It also features a 2-cycle multiplier and read-while-write capabilities.  The chip has a 100,000 write/erase cycle endurance for its EEPROM, SRAM, and external memory.

JTAG (the IEEE standard for debugging) allows engineers to access and control the inputs and outputs of electronic systems. This chip has extensive debug capabilities, including boundary-scan capabilities in accordance with the JTAG standard.

It also has on-chip support for programming Flash, EEPROM, Fuses, and Lock Bits. Additionally, it has two 16-bit timer/counters, a real-time counter, and two 8-bit PWM channels.

There are also six PWM channels with programmable resolution from 2 to 16 bits. Additionally, the chip has an 8-channel, 10-bit analog-to-digital converter, an output compare modulator, and single-ended channels.

What is ATmega128?

The ATmega128 is a microcontroller that is used in many different kinds of devices.

It is a popular choice for devices that need high speed and low power consumption. The ATMEGA128-16AU is a high-performance, low-power 8-bit AVR RISC-based microcontroller that includes 4KB of EEPROM, an 8-channel 10-bit A/D converter, and a JTAG interface for on-chip debugging.

The device can handle throughput of up to 16 MIPS at 16MHz, and it runs between 4.5 to 5.5V.

ATmega128 User Manual

The ATmega128 is an 8-bit microcontroller based on the AVR enhanced RISC architecture. It is low-power and has a wide range of applications. The ATmega128 can achieve high performance by executing powerful instructions quickly. This allows the system designer to optimize power consumption versus processing speed. The AVR core has a wide range of instructions and 32 general purpose working registers.

All the registers are directly connected to the Arithmetic Logic Unit (ALU), so two registers can be accessed in one single instruction executed in one clock cycle.

The architecture results in more efficient code, which can achieve throughputs up to ten times faster than conventional microcontrollers.
