ATMEGA48PA-MU Description

Short technical summary and product information.

The ATMEGA48PA-MU is a high-performance, low-power 8-bit AVR microcontroller from Microchip Technology. It features 4KB of in-system self-programmable Flash program memory, 512B of internal SRAM, and 256B of EEPROM with high endurance of 10,000 write/erase cycles for Flash and 100,000 for EEPROM. The device operates at speeds up to 20MHz, delivering up to 20 MIPS throughput.

 

This microcontroller includes a rich set of peripherals: two 8-bit timers, one 16-bit timer, six PWM channels, an 8-channel 10-bit ADC, and serial communication interfaces including I²C, SPI, and USART. It also features a brown-out detect/reset, power-on reset, and a watchdog timer. The operating voltage range is 1.8V to 5.5V, and it is rated for an industrial temperature range of -40°C to 85°C.

 

The ATMEGA48PA-MU is supplied in a 32-VFQFN exposed pad package (32-VQFN 5x5mm) for surface mount assembly. It is part of the ATmega48A/PA/88A/PA/168A/PA/328/P family, offering a scalable memory and feature set for embedded control applications.
