The ATMEGA48A-AU is an 8-bit microcontroller based on the AVR enhanced RISC architecture from Microchip Technology. It features 4KB of in-system self-programmable flash memory, 512 bytes of SRAM, and 256 bytes of EEPROM. The device operates at a maximum clock frequency of 20MHz, delivering up to 20 MIPS throughput. It supports a wide supply voltage range of 1.8V to 5.5V, with full speed operation at 4.5V to 5.5V for 20MHz.
This microcontroller integrates a rich set of peripherals including two 8-bit timers, one 16-bit timer, six PWM channels, an 8-channel 10-bit ADC, and multiple serial interfaces (I²C, SPI, USART). It also features brown-out detection, power-on reset, watchdog timer, and internal oscillator. The device includes six sleep modes to optimize power consumption, with typical power-down current as low as 0.1µA.
The ATMEGA48A-AU is well-suited for a variety of embedded applications such as industrial control, sensor interfaces, and consumer electronics. Its low-power operation and high-performance make it ideal for battery-powered devices.
The microcontroller is available in a 32-lead TQFP package (7x7mm) with a 0.80mm pitch and is surface mountable. It operates over an industrial temperature range of -40°C to 85°C.
