4KB 2K x 16 FLASH AVR 8-Bit Microcontroller AVR® ATmega Series ATMEGA48A 32 Pin 20MHz 5V 32-TQFP
ATMEGA48A-AU Description
The ATMEGA48A-AU is a 8-bit high-performance AVR RISC-based Microcontroller combines 4kB 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 2-wire serial interface, SPI serial port, 6-channel 10-bit A/D converter, programmable watchdog timer with internal oscillator and five software selectable power saving modes. The device operates between 1.8 to 5.5V. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed. The AVR core combines a rich instruction set with 32 general purpose working registers.
