2.2 Clocking
The Kinetis MCUs start up from an internal digitally controlled oscillator (DCO). Software can enable
one or two external oscillators if desired. The external oscillator for the Multipurpose Clock Generator
(MCG) module 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 EXTAL pin of the main external oscillator can also be driven directly from an external clock source.
The TWR-K60N512 features a 50 MHz on-board clock oscillator as seen in sheet 4 of the schematics.
However, when the K60 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-K60N512 provides
the option (see description for J6 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 K60 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 2.10 “Ethernet” for more information.
2.3 System Power
In stand-alone operation, the main power source for the TWR-K60N512 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 5 of the TWR-K60N512 schematics for more details.
When installed into a Tower System, the TWR-K60N512 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-K60N512 will default to the off-board source.
The 3.3V power supplied to the MCU is routed through a jumper, J8. The jumper shunt 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 K60 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-K60N512 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 J9 in Table 5 “TWR-K60N512 Jumper Table” for more information.

2.10 Ethernet
The K60N512 features a 10/100 Mbps Ethernet MAC with MII and RMII interfaces. The TWR-K60N512
routes the RMII interface signals from the K60 MCU to the Primary Connector, allowing the connection
to an external Ethernet PHY device on a Tower peripheral module.
When the K60 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-K60N512 provides the option (see description
for J6 in 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-K60N512-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-K60N512.
Table 4. Ethernet operation jumper settings
2.11 USB
The K60N512 features a USB full-speed/low-speed OTG/Host/Device controller with built-in
transceiver. The TWR-K60N512 routes the USB D+ and D- signals from the K60 MCU to the Primary

4 Input/Output Connectors and Pin Usage Table
The following table provides details on which K60N512 pins are using to communicate with the LEDs,
switches, and other I/O interfaces onboard the TWR-K60N512.
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-K60N512 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-K60N512 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.
