2.2 Clocking
The Kinetis MCUs start up from an internal digitally controlled oscillator (DCO). Software can enable
one, two, or three external oscillators if desired. Two of the external oscillators provide clocks to the
Multipurpose Clock Generator (MCG) module and can range from 32.768 KHz up to a 32 MHz crystal or
ceramic resonator. The external oscillator for the Real Time Clock (RTC) module accepts a 32.768 kHz
crystal.
The EXTAL0 and EXTAL1 pins of the main external oscillators can also be driven directly from an
external clock source. The TWR-K70F120M features a 50 MHz on-board clock oscillator connected to
EXTAL0 as seen in sheet 4 of the schematics. However, when the K70 Ethernet MAC is operating in
RMII mode, synchronization of the MCU input clock and the 50 MHz RMII transfer clock is important.
In this mode, the MCU input clock must be kept in phase with the 50 MHz clock supplied to the
external PHY. Therefore, the TWR-K70F120M provides the option (see jumper description in Table 5)
to select the clock input to the MCU from 1) the on-board 50MHz source or 2) an external clock from
the CLKIN0 pin on the Primary Connector. When the K70 is operating in Ethernet RMII mode, the
Tower peripheral module implementing the RMII PHY device should drive a 50 MHz clock on the
CLKIN0 signal that is kept in phase with the clock supplied to the RMII PHY. Refer to section 2.13
“Ethernet” for more information.
The TWR-K70F120M also includes a 12MHz crystal connected to EXTAL1/XTAL1.
2.3 System Power
In stand-alone operation, the main power source for the TWR-K70F120M module is derived from the
5.0V input from either the USB mini-B connector, J13, or the debug header, J11, when a shunt is placed
on jumper J12. A low-dropout regulator provides a 3.3V supply from the 5.0V input voltage. Refer to
sheet 6 of the TWR-K70F120M schematics for more details.
When installed into a Tower System, the TWR-K70F120M can be powered from either an on-board
source or from another source in the assembled Tower System. If both the on-board and off-board
sources are available, the TWR-K70F120M will default to the off-board source.
The 3.3V power supplied to the MCU is routed through two jumpers, J8 and J20. J8 can be supplies
VDD to the processor and also VDD_INT as long as J20 is installed. J20 supplies VDD_INT to the
processor. The jumper shunts can be removed to allow for either 1) alternate MCU supply voltages to
be injected or 2) the measurement of power consumed by the MCU.

2.3.1 RTC VBAT
The Real Time Clock (RTC) module on the K70 has two modes of operation, system power-up and
system power-down. During system power-down, the RTC is powered from the backup power supply,
VBAT. The TWR-K70F120M provides a battery holder for a coin cell battery that can be used as the
VBAT supply. The holder can accept common 20mm diameter 3V lithium coin cell batteries (e.g. 2032,
2025). Refer to the description J17 in Table 5 “TWR-K70F120M Jumper Table” for more information.
2.4 Debug Interface
There are two debug interface options provided: the on-board OSJTAG circuit and an external Cortex
Debug+ETM connector.
2.4.1 OSJTAG
An on-board MC9S08JM60 based Open Source JTAG (OSJTAG) circuit provides a JTAG debug interface
to the K70FN1M0. A standard USB A male to Mini-B male cable (provided) can be used for debugging
via the USB connector, J13. The OSJTAG interface also provides a USB to serial bridge. Drivers for the
OSJTAG interface are provided in the P&E Micro Kinetis Tower Toolkit (available on the included DVD).
2.4.2 Cortex Debug+ETM Connector
The Cortex Debug+ETM connector is a 20-pin (0.05") connector providing access to the SWD, SWV,
JTAG, cJTAG, EzPort and ETM trace (4-bit) signals available on the K70 device. The pinout and K70 pin
connections to the debug connector, J11, is shown in Table 1Table 1.
NOTE: The TRACE_CLKOUT signal is not connected to the debug connector by default. In order to use
trace functionality R137 should be populated and R138 and R11 should be removed.

the TWR-K70F120M. Refer to Table 6 “I/O Connectors and Pin Usage Table” and Table 7 “TWRK70F120M Primary Connector Pinout” for more information.
2.5 Graphical LCD Interface
The K70FN1M0 processor includes an on-chip graphical LCD controller module. The module is not used
directly on the TWR-K70F120M board, but the LCD signals are routed to the Secondary connector,
allowing the connection to an external LCD or additional circuitry on a Tower peripheral module.
The TWR-LCD-RGB will provide an LCD panel and all required external circuitry so that it can interface
directly to the TWR-K70F120M. This is an easy way to evaluate the graphical LCD module on the K70
processor.
2.6 DDR2 Memory
The TWR-K70F120M includes 1Gb of DDR2 memory (MT47H64M16HR-25). The board also includes a
DDR regulator that provides the main 1.8V supply for the memory and the processors SDRAM pads as
well as VTT and VREF voltages.
2.7 NAND Flash
The TWR-K70F120M includes 2Gb of SLC NAND flash memory (MT29F2G15ABAEAWP). The data lines
used for the NAND flash are shared between the NAND flash controller and the FlexBus interface.
Internal arbitration logic in the processor allows for dynamic sharing between the NAND flash and
FlexBus interfaces.
2.8 Infrared Port
An infrared transmit and receive interface is implemented on the board. The CMT_IRO pin directly
drives an infrared diode. The receiver uses an infrared phototransistor connected to an on-chip analog
comparator through a low-pass filter. Internal to the K70 device, the output of the analog comparator
can be routed to a UART module for easier processing of the incoming data stream.
2.9 Accelerometer

2.13 Ethernet
The K70FN1M0 features a 10/100 Mbps Ethernet MAC with MII and RMII interfaces. The TWRK70F120M routes the RMII interface signals from the K70 MCU to the Primary Connector, allowing the
connection to an external Ethernet PHY device on a Tower peripheral module.
When the K70 Ethernet MAC is operating in RMII mode, synchronization of the MCU clock and the 50
MHz RMII transfer clock is important. The MCU input clock must be kept in phase with the 50 MHz
clock supplied to the external PHY. Therefore, the TWR-K70F120M provides the option (see jumper
descriptions Table 5) to clock the MCU from an external clock from the CLKIN0 pin on the Primary
Connector. The Tower peripheral module implementing the RMII PHY device should drive a 50 MHz
clock on the CLKIN0 pin that is kept in phase with the clock supplied to the RMII PHY.
The TWR-SER module that comes as part of the TWR-K70F120M-KIT provides a 10/100 Ethernet PHY
that can operate in either MII or RMII mode. By default the PHY is boot strapped to operate in MII
mode; therefore jumper configuration changes may be required. Table 4 shows the settings for proper
interoperability between the Ethernet interface on the TWR-SER and the TWR-K70F120M.

2.14 USB
The K70FN1M0 features two different USB modules--a USB full-speed/low-speed OTG/Host/Device
controller with built-in transceiver and a high-speed OTG/Host/Device controller that requires a
external ULPI PHY.
2.14.1 FS/LS USB
The TWR-K70F120M routes the USB D+ and D- signals from the K70 MCU to the Primary Connector,
allowing the connection to external USB connectors or additional circuitry on a Tower peripheral
module.
The TWR-SER module included as part of the TWR-K70F120M-KIT provides a USB OTG/Host/Device
interface with a mini-AB USB connector. There are many configuration options that can be selected to
evaluate different USB modes of operation. By default, the TWR-SER is configured for USB Device
operation. Please refer to the documentation included with the TWR-SER for more information on the
configuration options.
2.14.2 HS USB
The TWR-K70F120M routes the ULPI interface signals for the high-speed USB module to the Secondary
Connector allowing the connection to an external ULPI PHY or additional circuitry on a Tower
peripheral module.
The TWR-SER2 module includes a ULPI PHY that can be used with the TWR-K70F120M in order to
evaluate the high-speed USB functionality. The TWR-SER2 is not included as part of the TWRK70F120M-KIT, but the boards can be ordered individually from Freescale.
2.15 Secure Digital Card Slot
A Micro-Secure Digital (SD) card slot is available on the TWR-K70F120M connected to the SD Host
Controller (SDHC) signals of the K70 MCU. This slot will accept micro-SD memory cards. Refer to Table
6 “I/O Connectors and Pin Usage Table” for the SDHC signal connection details.
2.16 External Bus Interface – FlexBus
The K70 device features a multi-function external bus interface called the FlexBus interface controller
capable of interfacing to slave-only devices. The FlexBus interface is not used directly on the TWRK70F120M. Instead, a subset of the FlexBus is connected to the Primary Connector so that the external
bus can access devices on Tower peripheral modules. Refer to Table 7 “TWR-K70F120M Primary
Connector Pinout” and sheet 8 of the TWR-K70F120M schematics for more details.

4 Input/Output Connectors and Pin Usage Table
The following table provides details on which K70FN1M0 pins are used to communicate with the LEDs,
switches, and other I/O interfaces onboard the TWR-K70F120M.
Note: Some port pins are used in multiple interfaces on-board and many are potentially connected to
off-board resources via the Primary and Secondary Connectors. Take care to avoid attempted
simultaneous usage of mutually exclusive features.

5 Tower Elevator Connections
The TWR-K70F120M features two expansion card-edge connectors that interface to the Primary and
Secondary Elevator boards in a Tower system. The Primary Connector (comprised of sides A and B) is
utilized by the TWR-K70F120M while the Secondary Connector (comprised of sides C and D) only
makes connections to the GND pins. Table 7 provides the pinout for the Primary Connector.
