ATMEGA48PA-AU - ATMEL Function Overview

The ATMEGA48PA-AU is a 8-bit high-performance picoPower 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.
Advanced RISC architecture - On-chip 2-cycle multiplier
High endurance, non-volatile memory segments
QTouch® library support - Capacitive touch buttons, sliders and wheels
Peripheral features - Real time counter with separate oscillator
Power-on reset (POR) and programmable brown-out detection
Internal calibrated oscillator
External and internal interrupt sources
Six sleep modes - Idle, ADC noise reduction, power-save, power-down, standby and extended standby
-40 to +85°C Industrial operating temperature range
