The ATMEGA88-20PU belongs to the AVR ATmega series of microcontrollers and is designed for high-performance and low-power embedded applications.

It uses a RISC architecture with 131 instructions, most executing in a single clock cycle, enabling throughput of up to 20 MIPS at 20 MHz. The device integrates Flash memory, SRAM, EEPROM, timers, ADC, and communication peripherals, making it suitable for stand-alone embedded designs

PIC18F67J60 is an 8-bit microcontroller from Microchip Technology that integrates a full Ethernet controller (MAC + PHY) on the chip. This makes it suitable for embedded networking applications without needing an external Ethernet controller IC.

It belongs to the PIC18 family and is commonly used in industrial automation, IoT devices, embedded web servers, and networked sensors

The PIC18F67J60 combines a high-performance PIC18 microcontroller core with an IEEE-802.3 compliant Ethernet interface, allowing designers to create devices that communicate directly over Ethernet networks.

The microcontroller also integrates memory, peripherals, ADC modules, communication interfaces, and power-management features, reducing the need for additional components in embedded network designs

The TL084CN is a high-performance quad operational amplifier with JFET input stages and bipolar output stages. It contains four independent op-amps in a single package, designed for low noise, high input impedance, and fast response. These characteristics make it suitable for audio amplification, signal conditioning, filters, and instrumentation circuits.

JFET inputs provide very low input bias current and high input impedance, which helps minimize loading on sensitive circuits.
