Freescale analog ICs are manufactured using the SMARTMOS process, a combinational BiCMOS
manufacturing flow that integrates precision analog, power functions and dense CMOS logic together on a
single cost-effective die. All power channels are integrated using LFet45V technology.

Accessory Interface Board
The eXtreme Switch Gen4 Evaluation board may be used with the KITUSBSPIDGLEVME interface dongle
(shown below), which provides a USB-to-SPI interface. This small board makes use of the USB and SPI ports
built into Freescale’s MC68HC908JW32 microcontroller. The main function provided by this dongle is to allow
Freescale evaluation boards that have an SPI port to communicate with a PC through its USB port.
