TWR-K70F120M Block Diagram 2.1 K70FN1M0 Microcontroller The TWR-K70F120M module features the MK70FN1M0VMJ12. The K70 microcontroller family is part of the Kinetis portfolio of devices built around an ARM Cortex-M4 core. Refer to the K70 Family Product Brief and the K70 Family Reference Manual for comprehensive information on the MK70FN1M0VMJ12 device. The key features are listed here: 32-bit ARM Cortex-M4 core with DSP instructions 120MHz maximum core operating frequency 256 MAPBGA, 17mm x 17mm, 1.0mm pitch package 1.71V – 3.6V operating voltage input range 1 Mbyte of program flash, 128 Kbytes of static RAM DDR controller supporting DDR1, LPDDR1, and DDR2 memory NAND flash controller External bus interface Power management controller with 10 different power modes Multi-purpose clock generator with PLL and FLL operation modes 16-bit SAR ADC, 12-bit DAC High-speed analog comparator with 6-bit DAC Programmable voltage reference USB high-speed OTG controller USB full-speed/low-speed OTG/Host/Device controller with device charge detect 10/100 Mbps Ethernet MAC TWR-K70F120M Tower Module User's Manual Page 9 of 25 SPI, I2C (w/ SMBUS support), UART (w/ ISO7816, CEA709.1-B (LON), and IrDA support), CAN, I2S SD Host Controller (SDHC) GPIO with pin interrupt support, DMA request capability, digital glitch filtering Capacitive touch sensing inputs (TSI) Debug interfaces: JTAG, cJTAG, SWD Trace: TPIO, FPB, DWT, ITM, ETM, ETB 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. TWR-K70F120M Tower Module User's Manual Page 10 of 25 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. Table 1.

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 An MMA8451Q digital accelerometer is connected to the K70 MCU through an I2C interface and a GPIO/IRQ signal. Refer to Table 6 “I/O Connectors and Pin Usage Table” for connection details. 2.10 Potentiometer, Pushbuttons, LEDs The TWR-K70F120M features two pushbutton switches connected to GPIO/interrupt signals, one pushbutton connected to the master reset signal, four capacitive touch pad electrodes, four usercontrollable LEDs, and a potentiometer connected to an ADC input signal. Refer to Table 6 “I/O Connectors and Pin Usage Table” for information about which port pins are connected to these features. TWR-K70F120M Tower Module User's Manual Page 12 of 25 2.11 General Purpose Tower Plug-in (TWRPI) Socket The TWR-K70F120M features a socket 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 I2C, SPI, IRQs, GPIOs, timers, analog conversion signals, TWRPI ID signals, reset, and voltage supplies. The pinout for the TWRPI Socket is defined in Table 2. Refer to Table 6 “I/O Connectors and Pin Usage Table” for the specific K70 pin connections to the General Purpose TWRPI socket. Table 2.

Each TSI pin implements the capacitive measurement of an electrode. The TWR-K70F120M provides two methods for evaluating the TSI module. There are four individual electrodes on-board the TWR-K70F120M 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. The pinout for the Touch TWRPI socket is defined in Table 3. Refer to Table 6 “I/O Connectors and Pin Usage Table” for the specific K70 pin connections to the Touch TWRPI socket. TWR-K70F120M Tower Module User's Manual Page 13 of 25 Table 3.

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. Table 4.

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. Note: In order to use the USB module in true OTG mode, VREGIN must be powered before the USB cable is plugged in. By default the board does not support this. The board can be modified by removing the jumper on J1, then directly connecting P5V_ELEV (or another 5V net that will be active during testing) to pin1 of J1 so that VREGIN has a 5V supply independent of the USB port on the TWR-SER board. 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 TWR-K70F120M Tower Module User's Manual Page 15 of 25 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. 3 Jumper Table There are several jumpers on the TWR-K70F120M that provide configuration selection and signal isolation. Refer to the following table for details. The default installed jumper settings are shown in bold with asterisks. Table 5.

Connect VDD and VDD_INT rails together Isolate MCU VDD_INT from power supply (allows for external supply or power measurements) 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. Table 6.
