ATMEGA88A-MU

The ATMEGA88A-MU is an 8-bit AVR microcontroller from Microchip Technology, part of the AVR ATmega series. Built on an advanced RISC architecture, it executes instructions in a single clock cycle and achieves throughput up to 20 MIPS at 20 MHz. The device includes 8KB of in-system programmable Flash memory, 1KB of SRAM, and 512 bytes of EEPROM, along with 23 general-purpose I/O lines.

The microcontroller operates from a 1.8V to 5.5V supply and over a -40°C to 85°C temperature range. It provides an 8-channel 10-bit ADC, I²C, SPI, and UART/USART interfaces, as well as on-chip peripherals such as timers, PWM, watchdog timer, brown-out detection, and power-on reset. Flash endurance is rated at 10,000 write/erase cycles and EEPROM at 100,000 cycles, with data retention of 100 years at 25°C.

The ATMEGA88A-MU is supplied in a 32-VQFN (5x5mm) surface-mount package with an exposed pad. Its low-power modes, including 0.1µA power-down current, make it suitable for battery-powered and IoT designs. Typical applications include consumer electronics, industrial control, automotive modules, medical devices, and embedded systems.
