ATMEGA88-20MU Description

Short technical summary and product information.

The ATMEGA88-20MU is an 8-bit AVR microcontroller from Microchip Technology, part of the ATmega88 family. It features 8KB of in-system self-programmable Flash memory, 1KB SRAM, and 512B EEPROM. Operating at up to 20 MHz, it delivers up to 20 MIPS throughput. The device includes 23 general-purpose I/O lines, an 8-channel 10-bit ADC, 6 PWM channels, and serial interfaces: SPI, I2C, and USART. It also integrates a brown-out detect/reset, power-on reset, and watchdog timer. The microcontroller operates over a supply voltage range of 2.7V to 5.5V and a temperature range of -40°C to 85°C. It is housed in a 32-pin VQFN package with exposed pad for surface-mount assembly, measuring 5x5 mm. This microcontroller is suitable for a wide range of embedded control applications requiring low power and high performance.
