ATMEGA48PA-PU Description

Short technical summary and product information.

The ATMEGA48PA-PU is a high-performance, low-power 8-bit AVR microcontroller from Microchip Technology. It features 4KB of in-system self-programmable Flash memory, 512B of SRAM, and 256B of EEPROM. Operating at up to 20MHz, it delivers up to 20 MIPS throughput. It supports a wide supply voltage range of 1.8V to 5.5V and operates from -40°C to +85°C.

 

The microcontroller includes 23 I/O pins, a 6-channel 10-bit ADC, 6 PWM channels, three timers/counters, and serial interfaces including I2C, SPI, and USART. It also features brown-out detection, power-on reset, and a watchdog timer. Housed in a 28-pin PDIP package with through-hole mounting, it is suitable for breadboard prototyping and industrial applications.
