ATMEGA2560-16U SMD Microcontroller

 The device achieves a throughput of 16 MIPS at 16 MHz and operates between 4.5-5.5 volts.

ATMEGA2560-16AU is the same Micro-controller that is used in Arduino Mega. SO you what to develop your own Arduino mega or develop a product based on Arduino Mega but you want to make a customized pcb then you will definitely require this IC. 

The high-performance, low-power Atmel 8-bit AVR RISC-based microcontroller combines 256KB ISP flash memory, 8KB SRAM, 4KB EEPROM, 86 general purpose I/O lines, 32 general purpose working registers, real time counter, six flexible timer/counters with compare modes, PWM, 4 USARTs, byte oriented 2-wire serial interface, 16-channel 10-bit A/D converter, and a JTAG interface for on-chip debugging.

By executing powerful instructions in a single clock cycle, the device achieves a throughput approaching 1 MIPS per MHz, balancing power consumption and processing speed.
