3 Hardware description
The TWR-K65F180M is a Tower MCU Module featuring the K65FN2M0VMI18 – an ARM
®
Cortex
®
-M4F based MCU with 2 MB on-chip flash, 256 KB on-chip SRAM, SDRAM controller and
dual USB controllers in a 169 pin MAPBGA package. It has a maximum core operating frequency of
180 MHz. It is intended for use in the Freescale Tower System but can operate as a stand-alone module.
An on-board debug circuit, OPENSDA, provides the SWD debug interface and power supply input
through a single USB mini-AB connector. The following sections describe the hardware in more detail.
This figure shows a block diagram for the TWR-K65F180M.
