2.2 Power Supply

The power supply circuit consists of the input-stage and three voltage-regulators. The regulators are switch-mode types (step-down).

Having the enables of the lower voltage supplies tied to the next higher voltage supply guarantees correct sequencing in the order required (5V0 → 3V3 → 1V2). Power-down/disconnect of powerdomains and/or -rails is not supported.

All regulators are supplied from the input-rail Vin_prot (filtered input voltage, no regulator-staggering).

SK-MB9EF120-002,-003

Hardware

UG-9E0010-11

- 10 - © Fujitsu Semiconductor Europe GmbH

Headers are connected to each voltage-rail to allow measuring the voltages. They should not be used to power custom electronics. Each stage provides a header connected to connect to the corresponding domain. Care must be taken when connecting to the 1V2-domain as noise on this rail will have much more impact on this rail due to the low absolute voltage.

2.2.1 Input Stage

The power-supply connector is a standard DC-plug for an AC-adapter. Allowed input voltage ranges from 9 to 12V, the adaptor should have a minimum power-rating of 12W (1A @ 12V).

After the power-switch, a reverse-voltage protection diode (D2) and an overvoltage protection device (D3) follow. The latter suppresses/damps high voltage surges from the AC-adaptor which would otherwise pass the following inductor and capacitors.

The inductor (L4) filters noise generated on-board, before it reaches the supply-cable which presents a good antenna for EMI. Filtering incoming noise is a bonus.

2.2.2 I/O Supplies

The 5V0 and 3V3 supplies are generated from the input-rail by two step-down switching regulators, each fixed to the desired output-voltage. As with all switching regulators, the designs are critical in terms of switching noise.

Each regulator provides up to 3A to its rail.

2.2.3 MCU Core supply

The 1V2 supply for the MCU core is generated by a switching regulator module which includes the inductor. It provides up to 3A to the rail.

2.2.4 Supply-Rail Monitor LEDs

Each supply-rail has its own LED-indicator. For the 1V2 rail, the LED is driven from the 3V3 rail, but switched from the 1V2 rail.

All three rails are monitored for drops by a system-voltage supervisor (U6).

2.2.5 Power distribution

The three stabilized voltages drive the various MCU power-domains either directly (single-voltage domains MCU_VDD, MCU_VDP3) or through a 3-pin jumper (dual-voltage domains VDP5, DVCC).

Additionally, there is a jumper before each domain's EMI-filter to allow injection of external supply or measuring the current-consumption of the domain.

2.3 Reset

Board-Reset can be generated by basically two sources. Both are connected to the system-reset which includes the microcontroller's reset-signal. Both sources can be disconnected from the resetnet by separate jumpers, thus excluding them from generating the reset-signal.

U6 generates the reset to the MCU and all other devices if one of the three system-voltages fails (System Voltage Supervisor). It also monitors a push-button, generating a short reset-pulse (~100µs) if this reset-button is pressed shortly. If the button is held pressed for some seconds, the reset-line will be permanently asserted until the button is released. Caution: the SVS monitors the on-board generated voltages, not the MCU power-domains. If any of the domains is supplied externally, it is left to the user to provide a proper reset signal.

The second source of reset is the debugging-connectors (JTAG or TRACE). This source can also be disconnected from the internal net.

A slight problem arises with the SVS output-signal having an internal current-source (pull-up) from the 3V3-domain. The MCU reset-input is located in the VDP5-domain, so an open-drain-driver (noninverting) is used which buffers the signal and has a pull-up resistor to VDP5 at the output, generating RST_X_VDP5.

SK-MB9EF120-002,-003

Hardware

UG-9E0010-11

RST_X_VDP5 also drives a LED which lights when the signal is active (low). On power-up or a press of the reset-button, the LED will flash according to the pulse generated by the system voltage supervisor. If the reset-button is pressed only for a short time, the pulse generated is too short to be noticed by the eye (but it is sufficient for the hardware). Holding down the button for >~4s, generates a permanent low-signal on reset until the button is released.

2.4 MCU Clocks

2.4.1 Main Clock

The MCU is clocked using its internal 4MHz crystal oscillator with Q1 as reference. As this is the main clock reference, it controls all timing of the microcontroller when selected.

2.4.2 Sub-Clock (Real-Time Clock Oscillator)

Q2 is a 32.768kHz crystal connected to the microcontroller's real-time clock oscillator. This clock is used to track time, while the other crystal oscillator is disabled.

2.5 On-Board Peripherals

The board provides two interfaces for external communication and two flash-devices for data-storage.

2.5.1 UART/USB-Serial Interface

Two port-signals (P0_45, P0_47) are connected to a USB-Serial converter chip (FT232R from FTDI). The ports can be controlled by USART0, thus allowing a serial interface between the MCU and a PC.

For the FT232R, drivers exist for all major operating systems (OSX, Linux, Windows) wither built-in (Linux) or for download (Windows). They provide a standard serial interface (“COM-port”/”ttyUSB”) to the applications, so any terminal program can be used to transmit data between the MCU and a PC.

The interface does not provide hardware-handshake, thus it is left to the software to provide some kind of flow-control and/or resynchronization, if necessary.

There is one LED per direction (RX, TX) signalling data-transmission. The two ports can be disconnected from the converter by two jumpers, freeing them for other usage

(the two signals are also available on the B2B connector CN1). The FT232R is powered from the USB-connector, making its operation independent on the power-

status of the board. However, as the supply of the serial interface I/O lines is powered from VDP5, the voltages here always match the requirements of the connected port-signals.

2.5.2 CAN-Bus Interface

Two ports from the MCU (P0_20, P0_21) are connected to a CAN-Bus transceiver. The CAN-bus itself is connected to a standard D-sub connector. The two signals are also RX and TX of the internal CAN0-controller.

As with the UART, jumpers are available for each port to disconnect them from the interface, freeing them for use from the B2B connector CN1.

2.5.3 Serial Flashes

There are two serial flash devices Spansion S25FL129P. One is connected to the MCU's HSSPI-port. It provides data-storage for applications. The second flash is of the same type, but connects to the GFXSPI-port which can be accessed by the graphics-controller without CPU intervention. The actual device chosen supports Quad-SPI mode at up to 80MHz, resulting in a max. data rate of 40MB/s.

2.6 Expansion Connectors

2.6.1 Board-to-Board (B2B) Connectors

On the bottom-side, there are two connectors (CN1, CN2). All MCU ports are available here, along with power-supply and additional control-signals like reset.

Layout and placement of the SK-MB9EF120-002,-003 allow to plug a Fujitsu Multi-I/O board (ADAFCR4-MULTIIO-001) under the board, providing direct access to the ports via standard-raster headers along with other features.

Alternatively, a custom PCB can be connected.

2.7 Debugging Facilities

The Starter-kit provides a JTAG-Interface on a 20-pin 2.54mm (0.1in) IDC-header for debugging. The header uses the standard ARM configuration.

The second facility consists of two ARM-standard trace-connectors (X3, X4). While they can be used together providing a 32-bit trace-port, the first (X3) can also be used solely with up to 16 trace-lines. Having the JTAG-signals also available on X3, debugging does not require further connections.

Only one connector-set may be used at the same time: either X2 or X3/X4, because some signals are shared between them. Debugging requires a conforming interface-adapter and corresponding software on the host system.

Installation

UG-9E0010-11

3 Installation

3.1 First Contact

After opening the box, please check first if all parts are included. If any parts are missing, ask your vendor.

The kit includes electrostatic sensitive devices. Unpacking should be done in an anti-static environment.

After removing the packing-material, check all parts and especially the PCB for damages. Also check the jumper-settings before initial powering up the board.

3.2 Engage

To power-up the board, first change the slider-switch (S1) to the “off”-position. Then connect the ACadapter to the AC-line. Connect the DC-plug to the board (X1), then turn on the slider-switch.

The AC-adaptor must provide 9-12V/12W DC. The positive (+) supply must be on the inner tip, while the negative supply (-/GND) is on the outer ring. The power-input includes reversepolarity protection for an unlimited time and a protection against surges from the AC-adapter. The latter must not be used as a voltage-regulator!

3.3 Lifesigns

After powering-up by turning on the power switch S1, the LED indicators for the supply-rails should turn on without noticeable delay.

Additionally, the reset-LED flashes once, signalling release of the reset-signal by the voltage monitor. If no LED lights op, turn off the power switch and check the polarity of the supply. If this is ok, or if

some power-LEDs are missing, flicker or show otherwise strange behaviour, check the power-rails for shorts to GND and each other before retrying.

If the reset-LED flashes from time to time (maybe with a constant frequency), check if the powersupply used can satisfy the current requirements and measure the voltages on the power-rails. Most times this occurs; one or multiple power-rails are at the edge of the SVS' trigger-level and drop below, eg. if more current is drawn by a device.

Use HDR1-3 and 6 to measure voltages. Never short these Headers!

4 Configuration and Test-Points

4.1 Jumpers

The SK-MB9EF120-002,-003 provides multiple options to access signals and configure its properties. For this, it has two variants of jumpers:

(regular) Jumpers consist of two or three pin-headers and a small cap. They can be changed

without extra tools. They are used where changes are likely to occur. Wide jumpers use a 2.54mm raster, while small jumpers use 2.00mm . The former are used for power-connections where also measuring may be required, while the latter are sole configuration jumpers.

solder-jumpers change more basic options, the vast majority of applications do not require

changing them from their defaults. A solder-jumper is either a single 0R0 resistor or two resistors of which only one may be placed. For the latter, a shared pad is often used to avoid placing both resistors accidentally.

On wide jumpers, the cap can be replaced by an ampere meter to measure current. However, care must be taken to avoid inducing noise into the connected cables. Alternatively, if the cap is removed, external power can be feed into the corresponding domain. Caution: do not back-drive current into

the supply-rails. Check the schematics before connecting an external power-supply to a jumper's output pin (the pin which drives the power-domain). Double-check before powering up!

DVCC, AVCC5 and VDP5 (see further description below) must be set to the same voltage-rail when zero point detection (ZPD) on any of the SMC ports is to be used. Check the datasheet for further requirements on the combination of voltages.

When using external supplies, the allowed voltages specified in the datasheet must be observed. This also applies to the ports driven by the domains.

The crystal testpoints TP5 and 6 are very sensitive to noise and load-factors, especially capacitive loads can change the frequency dramatically. If possible, the clocks should be measured indirectly using a high-speed timer or SYSC_CKOT.

4.4 Status Display

For user information, there are four LEDs on the board. Each power-rail (the supply generated onboard), is monitored by a single LED.

In addition, the reset-LED shows the status of the reset-line. For the default configuration and no external reset (JTAG, button or from a plugged-under PCB), this is the status of the system-voltage supervisor (SVS). It will be lit if any voltage-rail is out of its allowed limits.

top O/P-2/3

The two B2B connectors provide all MCU ports, power supplies and control-signals.

5.1 B2B Connectors (CN1, CN2)

These two connectors provide all signals to a plug-under board like the Multi-IO-Board. Signals include all MCU ports as well as reset and power supplies from the SK-board.

Signals are always routed to these connectors, even if they are used on the SK-MB9EF120-002,-003 themselves. When using a signal on a plug-under board which is also connected to an on-board peripheral or connector, it must be disconnected from the on-board resource by pulling the corresponding jumper. Some signals can be disconnected separately, while other signals are disconnected as a whole function-block.

Fitting mates for the other board are SAMTEC QTH type connectors.
