ATMEGA48A-MMH Description

Short technical summary and product information.

The ATMEGA48A-MMH is an 8-bit AVR microcontroller from Microchip Technology, part of the ATmega family. It features a high-performance RISC architecture with 131 instructions, most executed in a single clock cycle. The device offers 4KB of in-system self-programmable Flash memory, 512B of SRAM, and 256B of EEPROM with high endurance (10,000 Flash/100,000 EEPROM write/erase cycles) and data retention of up to 100 years at 25°C.

 

Key peripherals include two 8-bit and one 16-bit timer/counter, six PWM channels, an 8-channel 10-bit ADC (on VQFN package), and serial interfaces: I²C, SPI, and UART/USART. The microcontroller operates from 1.8V to 5.5V and at clock speeds up to 20 MHz, delivering up to 20 MIPS throughput. It is suitable for a wide range of embedded applications requiring low power consumption and high performance.

 

The device is supplied in a 28-VQFN (4x4 mm) surface-mount package with 23 general-purpose I/O lines. It includes internal oscillator, brown-out detection, power-on reset, and watchdog timer. The operating temperature range is -40°C to 85°C.
