    Cautions Note: Opening this product can result in voiding the warranty. The internal workings of this product can only be accessed by Intermec service personnel. Integrated circuits on the printed circuit board (PCB) in the computer are very sensitive to damage by electrostatic discharge (ESD). Prevent ESD by always wearing skin contact ground straps firmly attached to the equipment metal base assembly when working inside of the computer.

  • Page 51: Processor Core

    Chapter 4 — Theory of Operation Processor Core Processor The CK30 platform is built around the Intel PXA255 “Cotulla” XScale processor (U1). The low-end configurations of the CK30 (CK30AA and CK30BA) use a 200MHz version of the PXA250 for cost reasons. The high-end configuration (CK30CA) uses a 400MHz version of the part.

  • Page 52: Memory

    The same CAS-before-RAS refresh period of 8µs is used for both 128Mbit and 256Mbit SDRAM densities. In the current CK30 32MB and 64MB configurations, the SDRAM occupies partition 0 of the processor’s SDRAM space. Provision is made through not-installed AND gate U3 to support 128MB SDRAM using 512MB chips.

    The microcontroller is flash-based and can be reprogrammed in-system through the Debug port (P1) behind the SD slot door (see “PSC PIC” on page 96). While the CK30 is on, the PSC functions as a peripheral of the power management code running on the PXA255, accepting commands and returning data over the I2C bus.

    PXA255 (See “PSC 12C Syntax” on page 59). CK30 internal temperature is sensed by thermistor RT3, read through a PSC A/D, and sent to the OS over the I2C bus in response to I2C command.

It is adhesively attached to the top surface of the CK30 top cover and connects to the main PCB connector J11 through a hole in the top cover. This facilitates keypad replacement in the field.

  • Page 78: Wakeup Keys

    However, by routing one keypad row line (KEY_RET0) straight to PXA255 GPIO1 (as well as to the FPGA), the CK30 enables a small number of keys to serve as system wakeup keys. CK30 Handheld Computer Service Manual...

    A Mini PCI bridge is implemented in the FPGA as a high-bandwidth interface to support Ethernet and 802.11g cards. The bridge is based on “LogiCore” PCI interface IP from Xilinx, and on PCI bridge IP from NMI, Ltd. CK30 Handheld Computer Service Manual...

  • Page 82 The bridge provides round-robin arbitration among PCI slots. This feature is not used in the CK30, since it has only one PCI slot but may play a role in future products that may have two slots. A separate arbiter is provided to arbitrate between the PCI interface and the scanner interface also implemented in the FPGA.
  • Page 83 This provides a means for the CK30 Mini PCI bridge to signal that the PCI clock is stopped, and for Mini PCI cards to request the PCI clock stay on or be restarted. See Mini PCI Specification, Revision 1.0, for details.

    USB_5V (the 5V power supplied by the USB host) is used only to detect the presence of a USB host; it is not used to power any CK30 hardware. It is divided down to 3.3V levels by R157 and R160, and routed (as signal USB_WAKE) to PXA255 interrupt input GPIO19.

    DB9 cables supplying +5V, instead of RI, on DSub pin 9. U23 and its charge pumps are left on while the CK30 is on, but it draws very little current with no RS-232 device attached. It is shut off during Suspend by the DOCK_EN signal from HCR register U11.

  • Page 101: Storage Card (Sd Card)

    The SD card is powered through FET Q10. Software normally turns on power through control signal SD_PWR_EN* only when an SD card is detected in the slot while the CK30 is on. Software is responsible for shutting off SD power in a critical battery situation. If SD power is still on when the system suspends, it is shut off in hardware by the “Type 2”...

    Beeper CK30 audio tones are simple square wave tones generated by one of the PXA255’s 2 Pulse Width Modulators. Tone duration is software- controlled, based on OS timer ticks.

    FPGA_BEEP would drive the audio amplifier. So far, this feature has not been needed. Audio amplifier U19 can also be driven from audio codec U18. This feature is included to enable future CK30 versions with VoIP support, and is not currently installed. Debug Support...

    Debug Board J33, J34 and J35 are 3 high-density 40-pin SMT board-to-board connectors providing debug board access to the CK30 system bus and control signals. These connectors are not installed on production boards, and so are not intended as a field debug facility, but could be soldered onto a production board to help diagnose a field problem as a last resort.

    OS Image For the current release (version 1.01.01.0229), the only way to upgrade the OS image is to cold boot the CK30 with an SD card containing an image of the OS image. The Primary bootloader boots the system and looks for a new image file on an installed SD card.

    Chapter 4 — Theory of Operation AD1 1-Bay Communications Dock The AD1 charges a single CK30 battery while on the unit. It also provides a DB9 male connector for serial communications, an 8-pin RJ45 connector for 10/100 Ethernet communications, a Type-B USB connector for USB communications and a 26-pin JAE connector for interfacing with the CK30.

    CK30 recharges in less than five hours on the AD2. J7, J8, and J9 are the contacts by which the CK30 battery interfaces to the charging circuitry. The voltage divider formed by R90 and R91 is used to notify the BQ2954 that a battery has been inserted.

    AC1. AC2 4-Bay Charging Dock The AC2 can charge four CK30 units at the same time. The AC2 uses the same PCB as the AD2. The only difference is that all communications related circuitry has been removed. The only function of the AC2 is to charge the battery of up to four CK30s simultaneously.
