ATMEGA88-20AUR

The ATMEGA88-20AUR is a high-performance, low-power 8bit AVR RISC-based microcontroller combines 8kB ISP flash memory, 1kB SRAM, 512byte EEPROM, an 8-channel/10-bit A/D converter and debugWIRE for on-chip debugging. The device supports a throughput of 20MIPS at 20MHz and operates between 2.7 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 high density non-volatile memory technology. The on-chip ISP flash allows the program memory to be reprogrammed in-system through an SPI serial interface, by a conventional non-volatile memory programmer, or by an on-chip boot program running on the AVR core. The boot program can use any interface to download the application program in the application flash memory.
