ATMEGA88-20AU Description

Short technical summary and product information.

The ATMEGA88-20AU is an 8-bit AVR microcontroller from Microchip Technology, based on the enhanced RISC architecture. The core executes most instructions in a single clock cycle at a maximum speed of 20MHz. It provides 8KB of in-system self-programmable Flash program memory, 1KB of SRAM, and 512 bytes of EEPROM.

 

The device includes 23 programmable I/O lines and a set of peripherals such as brown-out detection, power-on reset, PWM, and watchdog timer. For communication, it offers I2C, SPI, and UART/USART interfaces. An internal oscillator is built in, and an 8-channel 10-bit ADC supports analog signal acquisition. The operating supply voltage ranges from 2.7V to 5.5V.

 

The microcontroller is housed in a 32-TQFP (7x7 mm) surface-mount package, suitable for compact circuit boards. It is rated for an operating temperature range of -40°C to +85°C, making it applicable across industrial and consumer environments.
