ATmega88

The ATmega88 is an 8-bit AVR microcontroller developed by Atmel, now Microchip Technology. It is part of the AVR family, known for its RISC architecture and in-system programmable Flash memory. The ATmega88 features a single-cycle 8-bit RISC processor, a wide range of peripherals, and low power consumption.

Key features of the ATmega88 include 8 KB of self-programmable Flash memory for program storage, 1 KB of SRAM for data storage, and 512 bytes of EEPROM for non-volatile data storage. It operates at frequencies up to 20 MHz and typically consumes very little power, making it suitable for battery-powered applications.

The ATmega88 offers several integrated peripherals. These include three flexible timer/counters, a programmable USART for serial communication, an SPI serial interface, and a two-wire serial interface (I2C compatible). It also includes an 8-channel, 10-bit Analog-to-Digital Converter (ADC) for interfacing with analog sensors. The device is available in various packages, such as PDIP, TQFP, and QFN, allowing for flexibility in circuit board design.

The ATmega88 is widely used in embedded systems, hobbyist projects, and educational platforms due to its balance of features, performance, and cost-effectiveness. Its ease of use and extensive community support further contribute to its popularity. It can be programmed using the Atmel Studio integrated development environment (IDE) or other compatible tools, supporting C and Assembly languages.
