ATMEGA48A-MU

The ATMEGA48A-MU is a high-performance, low-power 8-bit microcontroller based on the AVR enhanced RISC architecture from Microchip Technology. It features 4KB of in-system self-programmable Flash program memory, 512 bytes of internal SRAM, and 256 bytes of EEPROM for robust data storage. The device operates at a maximum speed of 20 MHz, achieving up to 20 MIPS throughput.

This microcontroller includes a rich set of peripherals such as two 8-bit timers, one 16-bit timer, six PWM channels, and an 8-channel 10-bit ADC. It supports multiple serial communication protocols including I2C, SPI, and UART/USART, enabling seamless integration with sensors, displays, and other peripherals. The device also features a brown-out detect/reset, power-on reset, and a watchdog timer for reliable operation.

The ATMEGA48A-MU is housed in a 32-lead VQFN package with an exposed pad for improved thermal performance, and is designed for surface mount assembly. It operates over a wide voltage range of 1.8V to 5.5V and a temperature range of -40°C to +85°C, making it suitable for industrial and automotive environments. The internal oscillator eliminates the need for external clock components, simplifying board design.
