Page 4: Hardware Description
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. -
Page 5: Clocking
EXTAL0 and XTAL0 pins. System power In standalone operation, the main power source for the TWR-K65F180M is derived from the 5.0 V input from either the USB mini-B connector, J7, or the debugger header, J18, when a shunt is placed on jumper J21. -

J9. See sheet 5 of the TWR-K65F180M Schematics (document TWR-K65F180M-SCH) for further details. When installed into a Tower System, the TWR-K65F180M can be powered from either an on-board power source or from another power source in the assembled Tower System. If both the on-board and off-board power sources are available, the TWR-K65F180M will default to the off-board power source. -
Page 7: Cortex Debug Connector
The K65 device features a multi-function external bus interface called the FlexBus interface controller. This is capable of interfacing with slave-only devices. The FlexBus interface is not used directly on the TWR-K65F180M. Instead, a subset of the FlexBus is connected to the Primary Connector so that the “Error! Reference source external bus can access devices on Tower peripheral modules. -
Page 8: Sdram
SDRAM The TWR-K65F180M board contains 64 Mb SDRAM (32-bit width) which is connected to the K65 SDRAM controller. The SDRAM signals are multiplexed with Flexbus signals. See the K65 Family Reference Manual (document K65P169M180SF5RMV2) “Flexbus signal multiplexing” section and “SDRAM SDR signal multiplexing” section on how to use the Flexbus and SDRAM in multiplexed mode. -

3.11 General Purpose Tower Plug-in (TWRPI) socket The TWR-K65F180M features two sockets (J11 and J12) that can accept a variety of different Tower Plug-in modules featuring sensors, RF transceivers, and more. The General Purpose TWRPI socket provides access to I C, SPI, IRQs, GPIOs, timers, analog conversion signals, TWRPI ID signals, reset, and voltage supplies. -

Page 11: Ethernet And 1588
The K65FN2M0VMI18 features a 10/100 Mbps Ethernet MAC with MII and RMII interfaces. The TWR-K65F180M routes RMII interface signals from the K65 MCU to the primary elevator connector which enables a connection to an external Ethernet PHY that can be found on some Tower peripheral modules. - Page 12 Table 4.
