ATMEGA48-20MU Description

Short technical summary and product information.

The ATMEGA48-20MU is a low-power, high-performance 8-bit AVR microcontroller from Microchip Technology based on the enhanced RISC architecture. It executes powerful instructions in a single clock cycle, achieving throughputs close to 1 MIPS per MHz. The device features 4KB of in-system self-programmable Flash memory, 512B of internal SRAM, and 256B of EEPROM with high endurance (10,000 write/erase cycles for Flash, 100,000 for EEPROM).

 

This microcontroller operates at a supply voltage range of 2.7V to 5.5V and at a maximum speed of 20MHz, delivering up to 20 MIPS throughput. It includes 23 general-purpose I/O lines and a rich set of peripherals: two 8-bit timers, one 16-bit timer, six PWM channels, an 8-channel 10-bit ADC, and programmable watchdog timer. Connectivity options include I²C, SPI, and UART/USART interfaces.

 

The ATMEGA48-20MU is offered in a 32-VFQFN exposed pad package (supplier device package 32-VQFN 5x5mm) for surface-mount assembly. It is specified for an industrial temperature range of -40°C to +85°C, making it suitable for a wide variety of embedded control applications.
