ATMEGA88PA-MUR

ATMEL  ATMEGA88PA-MUR  微控制器, 8位, 低功率高性能, ATmega, 20 MHz, 8 KB, 1 KB, 32 引脚, MLF

The is a high-performance picoPower 8-bit AVR RISC-based Microcontroller combines 8kB ISP flash memory with read-while-write capabilities, 512byte EEPROM, 1kB SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible timers/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 1MIPS per MHz, balancing power consumption and processing speed. The device is manufactured using Atmel"s high density nonvolatile memory technology. The on-chip ISP flash allows the program memory to be reprogrammed in-system through an SPI serial interface.
