ATmega48A-AU SMD Microcontroller

Atmega48A-AU SMD Microcontroller in TQFP32 package

ATmega48 microcontroller comes in TQDP32 package. ATmega48 microcontroller is a high performance Microchip 8-bit AVR® RISC-based picoPower® microcontroller combines 4 KB ISP Flash memory, 256B EEPROM, 512B SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible timer/counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented Two-Wire serial interface, SPI serial port, 6-channel 10-bit A/D converter (8-channels in TQFP and QFN/MLF packages), programmable watchdog timer with internal oscillator, and five software selectable power saving modes. The device operates between 1.8-5.5 volts.

By executing powerful instructions in a single clock cycle, ATmega48A-AU microcontroller achieves throughputs approaching one MIPS per MHz, balancing power consumption and processing speed.
