2 Hardware Description
The TWR-K40X256 is a Tower Controller Module featuring the MK40X256VMD100—an ARM Cortex-
M4 based microcontroller with segment LCD and USB 2.0 full-speed OTG controllers in a 144 MAPBGA
package with a maximum core operating frequency of 100MHz. It is intended for use in the Freescale
Tower System but can operate stand-alone. An on-board debug circuit, OSJTAG, provides a JTAG
debug interface and a power supply input through a single USB mini-AB connector. Figure 5 shows a
block diagram of the TWR-K40X256. The following sections describe the hardware in more detail.
