Freescale specifies the maximum allowed junction temperature of the processor to be limited to 105C, which translates to the following processor case temperatures: Processor Speed Max Ambient Temperature w/o Thermal Pad Max Case Temperature 454 MHz 59 C 84 C 360 MHz 68 C 88 C 261 MHz 69 C 88 C 64 MHz 99 C 102 C The ConnectCard for i.MX28 has been built to function up to 65C at full clock speed without a thermal pad attached (not included in the development kit) between the processor and the development board, and has been checked up to 75C with the thermal pad attached. There is a large ground area left open under the module on the development board under the module to accommodate the thermal pad. Bergquist makes thermal pad material in various thicknesses. The CCi.MX28 has been characterized using a combination of 2500S20 and 2000S40 pads from Bergquist. Designs using the ConnectCard for i.MX28 need to ensure that the rating maximums above are not exceeded in the application. Case temperature can be measured using an external probe on the center of the i.MX28 processor package, and the junction temperature can be monitored in software through an on-die temperature sensor provided in the i.MX processor. Because of the limitation above, active and/or passive thermal management may be required (thermal pad, airflow, clocking, etc.) like the Bergquist 2500s20 and 2000S40 thermal pads. For more information on thermal consideration with the i.MX28 processor see the Freescale i.MX28 data sheet. 31 Pin LCD, JTAG, and ETM Connector The module uses a 31 pin ZIF connector for the LCD, JTAG and ETM connections.

The configuration of the resources will depend on the system requirements, and some planning may be required to set up the available interfaces in a particular application. DC Power The ConnectCard for i.MX28 has 5V and Battery inputs: The 5V supply will have a maximum of 5.25V and a minimum operating voltage of 4.75V. This supply is assumed to come from a regulated supply with about 1A of current capability. The development board supply can generate up to 1.5A. The Battery voltage needs to be between 3.4 and 4.242V. If both 5V and Battery supplies are connected the module will automatically use the 5V supply. In addition, there is a +3.3V line coming out of the module which can be used to power external circuitry. This supply can be disabled in low power mode so that it can be used as a low power configuration signal. Thermal Considerations At high clock rates the i.MX28 will pull more current. The ConnectCard for i.MX28 has been built to function up to 65C at full clock speed with a thermal pad attached (not included in the development kit) between the processor and the development board. There is a large ground area left open under the module on the development board under the module to accommodate the thermal pad. Bergquist makes thermal pad material in various thicknesses. The CCi.MX28 has been characterized using a combination of 2500S20 and 2000S40 pads from Bergquist. Consult the Freescale data sheet for the i.MX28 for thermal requirements. System Boot The ConnectCard for i.MX28 boot process begins at Power On Reset when the hardware reset logic forces the ARM core to begin execution starting from the on-chip boot ROM. Boot ROM © 2013 Digi International, Inc. 19 Conn ectCor e™ for i.MX 28™ Ha rdwa re Re fe rence code uses the state of the internal register BOOT_MODE[1:0] as well as the state of various eFUSEs and/or GPIO settings to determine the boot flow behavior of the module. The following Boot modes are supported: Boot from FLASH Boot from SD Card Boot from USB Boot from JTAG Each mode is selected by applying the proper bit pattern to LCD_D00, LCD_D01, LCD_D02, LCD_D03, and LCD_D04. The default boot mode is FLASH. No internal eFUSEs have been set. For more information on boot modes, please refer to chapter 12 of the Freescale documentation. Audio System The audio system is using an SAIF interface configured as I2S. LCD System The LCD is available through a 31 pin ZIF connector on the top side of the module (see variants for availability). The development kit uses a cable from NICOMATIC (part number 050P331K0076-406406 ). The default LCD setting is for 18 bit color, and the development board is set up for this setting as well. A special 24 bit color option is available (not supported in current variant list) but will disconnect the JTAG functionality. Touch screen functionality is supported by connecting LRADC2-5. There are multiple SPI ports available to communicate with a SPI touch screen controller (the development board uses SSP1). PWM0,1,3,4,5 and 6 are available to use for backlight control (the development board uses PWM0). GPIO In general any of the modules digital pins can be set as a GPIO. There are 3 available states for any GPIO-- low, high , and high impedance. Each of the GPIO pins is capable of functioning on either at 1.8 or 3.3V as well as an interrupt/trigger pin. Each individual GPIO can be dynamically programmed at any time to be in either: High-impedance (for input, three-state, or open-drain applications); Low; High; or Controlled by one of the three selectable i.MX28 peripheral module interfaces. The state of any GPIO pin can be read at any time regardless of its configuration. Analog pins may not be set as GPIO. The following functions cannot be used for GPIO functions: Ethernet USB LRADC (although muxed functions can be used) HSADC One Wire (Technically it could be by controlling the I2C line) JTAG © 2013 Digi International, Inc. 20 Conn ectCor e™ for i.MX 28™ Ha rdwa re Re fe rence PSWITCH RESET DC connections (5V, Battery, and GND) Interfaces 1- Wire The ConnectCard for i.MX28 provides a 1-wire interface to communicate with 1-wire devices such as EEPROMs, secure memory and sensors. The required protocol for accessing the generic 1-wire device is defined by Maxim. The Maxim DS2482-100 interface is used for 1Wire communication. The 1-wire interface uses a strong 3.3V pull-up. ADCs and Touc h Scr een The ConnectCard for i.MX28 provides both Low-Resolution ADC's (LRADC) and a High speed ADC (HSADC). In either case, the ADC's have 12 bit resolution and an absolute accuracy of 1.3%. LRADC's can operate with up to 3.3V inputs, with an absolute accuracy of 1.3%. In addition to ADC functions, LRADC 2-6 can also be used for touch screen control (2-5 are used on the development board for touch screen control). There are 16 ADC channels available, the channel assignments are shown in the table below: ADC Channel Number 0-6 Assignment LRADC0-6 measure the voltage on the seven application-dependant LRADC pins. LRADC2-6 can be used for 4/5-wire touch screen control. LRADC6 can be used for a wiper of 5-wire touch screen controller and external temperature sensing, but they cannot be enabled at the same time in hardware configuration. Dedicated to measuring the battery voltage. 8, 9 Dedicated to measuring the internal die temperature. 10 Dedicated to measuring the internal 3.3V rail, and for calibrating the voltage levels measured on the auxiliary channels. 11 Reserved input for analog testing. 12 Dedicated to measuring the internal 1.8V rail. 13 Dedicated to measuring the internal 1.5V rail. 14 Dedicated to measuring the band gap reference voltage and can be used to calibrate out a portion of the LRADC measurement error. In most cases the band gap reference error dominates the total LRADC error, and this calibration is not helpful. 15 Dedicated to measuring the 5V supply to detect possible issues with the 5V rail dropping. © 2013 Digi International, Inc. 21 Conn ectCor e™ for i.MX 28™ Ha rdwa re Re fe rence The HSADC is capable of measuring up to 2Msps, and can be used in conjunction with the PWM's to generate signals for external devices like a linear image scanner sensor. The HSADC can be triggered to start the conversion of an analog source in three modes: Trigger by Software Trigger signal generated by the PWM block Trigger by an input pin from an external source CAN The ConnectCard for i.MX28 includes two FlexCAN2 controllers which are compatible with the CAN 2.0B protocol specification. The CAN Protocol Interface (CPI) manages the serial communication on the CAN bus, requesting RAM access for receiving and transmitting message frames, validating received messages and performing error handling. The Message Buffer Management (MBM) handles Message Buffer selection for reception and transmission, taking care of arbitration and ID matching algorithms. The CAN bus can operate up to 1Mbps The FlexCAN2 controllers require additional hardware, an example of this circuitry can be found on the development board. Ethernet The ConnectCard for i.MX28 provides up to two 10/100 Mbps Ethernet connections (see variants table for number of Ethernet connections). The MAC and PHY are on the module, and the Magnetics and Jack need to be provided external to the module. The connections from the module are differential pairs for the TX and RX ports. In variants with 1 Ethernet 2 USB ports are provided. USB The ConnectCard for i.MX28 includes up to two high-speed Universal Serial Bus (USB) version 2.0 controllers and integrated USB Transceiver Macrocell Interface (UTMI) PHYs. The i.MX28 device interface can be attached to USB 2.0 hosts and hubs running in the USB 2.0 high-speed mode at 480 Mbps. It can be attached to USB 2.0 full-speed interfaces at 12 Mbps. Note that a dual-device configuration is not supported. The USB controllers and integrated PHYs support high-speed Host modes for peer-to-peer file interchange. The USB controller can also be configured as a high-speed host. Each USB is a dynamically configured port that can support up to seven RX and seven TX endpoints besides EP0, each of which may be configured for bulk, interrupt, or isochronous transfers. USB0 is a high speed, OTG-capable universal serial bus. The ConnectCard for i.MX28 can operate as a host controller that can support eight endpoints: one control, one bulk-out, one bulk-in, and five flexible endpoints. Further, it can negotiate with another OTG system to be either the host or the device in a peer connection. Note that USB1 is a host-only USB port. Variants with two USB ports have only one Ethernet port, as noted in the Ethernet section above. © 2013 Digi International, Inc. 22 Conn ectCor e™ for i.MX 28™ Ha rdwa re Re fe rence I2C The ConnectCard for i.MX28 contains 2 two-wire SMB/I2C bus interfaces. Each interface can act as a slave or a master on the SMB. The I2C interfaces are multiplexed with the DUART, and I2C0 is used for the DUART on the development board, and no termination resistors are on the module for this interface. I2C1 is used to run the 1-wire interface, and 2.2K ohm termination resistors are located on the module. The supply voltage of these resistors is 3.3V. The I2C bus is a standard two-wire serial interface for connecting the ConnectCard for i.MX28 to peripheral devices or host controllers. The I2C buss operates at a standard speed of up to 100Kbps and a fast speed of up to 400Kbps. The ConnectCard for i.MX28 can act as either master of slave on the I2C bus. This module is also capable of supporting multi-master configurations. The device address of the 1-wire bridge is 00, and cannot be used by other I2C devices connected to the I2C1 bus. SAI F (A u di o) The ConnectCard for i.MX28 includes a Serial Audio Interface (SAIF) configured as an I2S intervace. It is capable of transmitting and receiving in 16 or 24 bit audio, by connecting to an audio codec. A possible example circuit is shown in the development board schematics. A U A R Ts a n d D U A R T Up to four application UARTs (AUART), and 1 debug (console) DUART are available on the ConnectCard for i.MX28 module. The AUARTs are capable of running up to 3.25 Mbps, while the DUART is capable of speeds up to 115Kbps. Variants using the i.MX287 include flow control on all application UARTs. Through the DUART the CPU reads and writes data and control/status information through the APBX interface. The DUART does the serial to parallel conversions on data received from a peripheral device and the parallel to serial conversion on data transmitted to the peripheral device. The buffer size for the DUART is 32 bytes. Flow control is not included for the debug UART. P u l s e W i dt h M o d u l a t o r ( P W M ) The ConnectCard for i.MX28 module provides access to PWM0 through PWM6. The PWMs can be used in place of GPIO pins to control such things as LED Brightness, HSADC, and LCD backlight control. Independent output control of each phase allows 0, 1, or high-impedance to be independently selected for the active and inactive phases. Individual outputs can be run in lock step with guaranteed non-overlapping portions for differential drive applications. S y n c h ro n o u s S e r i a l P o r t s ( S P I , a n d S D ) The three available Synchronous Serial Ports on the ConnectCard for i.MX28 module can support SPI master and Slave modes up to 52MHz speeds. In addition SSP0 is capable of SD card functions including booting. Real Time Clock (RTC) The real-time clock (RTC) and alarm share a one-second pulse time domain. The watchdog reset and millisecond counter run on a one-millisecond time domain. The RTC, alarm, and © 2013 Digi International, Inc. 23 Conn ectCor e™ for i.MX 28™ Ha rdwa re Re fe rence persistent bits use persistent storage and reside in a special power domain (crystal domain) that remains powered up even when the rest of the chip is in its powered-down state. The ConnectCard for i.MX28 development board does not include a backup battery, so the RTC will not be maintained through power cycles. Liquid Crystal Display (LCD) Some versions of the ConnectCard for i.MX28 includes an LCD connector that is separate from the edge connector. Smart LCDs are available in a range of sizes and capabilities, from simple text-only displays to WVGA, 16/18/24 bpp color TFT panels. This device supports displays that support moving pictures and require the RGB interface mode (called DOTCLK interface in this document). Wi-Fi and Bluetooth The ConnectCard for i.MX28 is available with an Qualcom-Atheros 802.11 a b g n and BT4.0 interfaces. Wi-Fi data rates up to 150 Mbps (5GHz n-mode) are possible. For variants without BT a diversity antenna (using the 2 u.FL ports) is utilized for the 2.4GHz band. For variants with BT a single u.FL antenna connection for both bands is used. The module is built with coexistence in mind and handles the BT coexistence internally. Cellular coexistence filtering is onboard to aid in designing systems susceptible to cellular interference. A mini access point mode is available in the Wi-Fi with up to 5 clients. This mode is limited to non DFS channels. The channels available are shown below: US and Canada - 2.4 GHz band, 5.8, 5.15-5.25 GHz only EU - 2.4 GHz band only Japan - 2.4 GHz band only Embedded Trace Macrocell The ConnectCard for i.MX28 includes a stand-alone ARM CoreSight Embedded Trace Macrocell, ETM9CSSingle, which provides a instruction trace and a data trace for the ARM9 microprocessor. This function is available on the same connector as the LCD, and many of the pins are shared with the LCD controller. This feature is disabled by default. To enable Embedded Trace Macrocell, external hardware is needed to set LCD_D05 to high during reset (rever to the i.MX28 boot mode configuration). Re se t The reset pin on the module is low asserted. A low pulse will reset the module. There is an internal pull up resistor to 3.3V, so no external pull up resistor is needed. Re cov ery and Powe r The power pin is used to turn the ConnectCard for i.MX28 module on when only the battery supply is connected. This is done by connecting about 1V to the pin for 100ms. The power pin is also used to place the module in recovery mode. This is done by placing 3.3V on the pin for more than 5 seconds. The sb_loader can then be used to boot the part through the USB OTG (USB0) interface. © 2013 Digi International, Inc. 24 Conn ectCor e for i.M X53 NAND FLASH The ConnectCard for i.MX28 module includes either 128MB or 256MB of NAND FLASH from the Micron Technologies MT29F series.

One 5V regulator is set up to power the module from the 9VDC to 30VDC wall adaptor, the other 5V regulator is a buck boost regulator to power the USBs. The 4.2V regulator is set up to power the module through the BATT port. The 3.3V regulator powers both the development board and the XBee if so equipped. The development board has an ON/OFF switch, SW1. The power switch SW1 can switch both 9V-30VDC input power supply and 12VDC coming out of the optional PoE module (Digi P/N DG-ACC-POE). However, if a power plug is present on the DC power jack, PoE is disabled. The 5V and BATT module supplies can also come from an external jack. For the 5V external jack the voltage range is 4.75DC to 5.25VCD. For the external BATT supply the allowable range is 3.4VDC to 4.2VDC. The module will not auto boot from the BATT supply, but will from the 5V supply. If operating form only the BATT supply the POWER BUTTON will need to be pressed to turn the module on. The 3.3V board supply and XBee supply along with the 5V USB supply are powered from either the 5V or BATT module supplies, with the 5V supply being the primary and the BATT supply being the secondary supply. The module can be connected to both the 5V and BATT supply at the same time. When connected to both supplies the module will draw its power form the 5V supply, as will the board, USB, and XBee. © 2013 Digi International, Inc. 32 Conn ectCor e™ for i.MX 28™ Ha rdwa re Re fe rence Power over Ethernet (PoE) - IEEE802.3af PoE is only available through ENET0 on the development board.
