Microchip Technology, Inc. Microcontrollers ATMEGA168PB-AU

The ATmega48PB is an 8-bit microcontroller from the AVR family, operating at a maximum speed of 20 MHz. It features 4 KB of in-system programmable Flash memory, 512 bytes of SRAM, and 256 bytes of EEPROM. The device supports a wide operating voltage range of 1.8V to 5.5V and is rated for a temperature range of -40¬8C to 105¬8C. This microcontroller includes 27 programmable I/O lines and offers various peripheral features such as two 8-bit timer/counters, a 16-bit timer/counter, an 8-channel 10-bit ADC, and multiple communication interfaces including USART, SPI, and I¬=C. It also supports capacitive touch sensing through the Atmel QTouch library, making it suitable for applications requiring touch input. The ATmega48PB is designed for low power consumption, with active mode consumption at 0.35 mA and power-down mode at just 0.23 ¬µA. It is packaged in a 32-lead TQFP format, making it suitable for compact designs. The microcontroller is RoHS compliant, ensuring it meets environmental standards.
