ARM® Cortex™-M4 architecture with USB 2.0 full-speed OTG controller and 10/100 Mbps Ethernet MAC. The TWR-K60N512 is available as a stand-alone product or as a kit (TWR-K60N512-KIT) with the Tower Elevator Modules (TWR-ELEV) and the Tower Serial Module (TWR-SER). The TWR-K60N512 can also be combined with other Freescale Tower peripheral modules to create development platforms for a wide variety of applications.
TWR-SER – Serial module including USB host/device/OTG, Ethernet, CAN, RS232 and RS485 1.2 Features Figure 2 and Figure 3 show the TWR-K60N512 with some of the key features called out. The following list summarizes the features of the TWR-K60N512 Tower MCU Module:...

Callouts on back side of the TWR-K60N512 1.3 Getting Started Follow the Quick Start Guide found printed in the TWR-K60N512 box or the interactive DVD for the list of recommended steps for getting started. There are also lab walk-through guides available on the tool support page for the TWR-K60N512: http://www.freescale.com/TWR-K60N512.
USB mini-AB connector. Figure 4 shows a block diagram of the TWR-K60N512. The following sections describe the hardware in more detail. Tower Elevator Expansion Connectors 5.0V 3.3V SDHC, I S, SPI, I...
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.
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.
PTA7/FTM0_CH4/TRACE_D3 Note: Many of the trace signals connected to the debug connector are also connected elsewhere on the TWR-K60N512. Refer to Table 6 “I/O Connectors and Pin Usage Table” and Table 7 “TWR-K60N512 Primary Connector Pinout” for more information. 2.5 Infrared Port An infrared transmit and receive interface is implemented as shown in Figure 5 below.
Each TSI pin implements the capacitive measurement of an electrode. The TWR-K60N512 provides two methods for evaluating the TSI module. There are four individual electrodes on-board the TWR-K60N512 that simulate pushbuttons. Additionally, twelve TSI signals are connected to a Touch Tower Plug-in (TWRPI) socket that can accept Touch TWRPI daughter cards that may feature keypads, rotary dials, sliders, etc.
Reset 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.
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 Connector, allowing the connection to external USB connectors or additional circuitry on a Tower peripheral module.
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.
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.
