Intel®PXA27x Processor Developer’s Kit - User’s Guide 7
Introduction and Startup 1
The Intel®PXA27x Processor Developer’s Kit (kit), constitutes a software-development kit based
on Intel®PXA270 Processor. This kit provides all of the system components necessary for
Microsoft Windows* CE, Symbian*, Palm*, Linux, and other full-featured, handheld operating
system.
Note: The kit comes with a factory installed the Intel®PXA270 Processor.
The Intel®PXA270 Processor is the third implementation of the Intel XScale®microarchitecture
family, featuring an improved LCD controller, expanded card interface, and more conservative
power management features. It is also the first processor in the family to include a baseband
interface, integrated SRAM, a camera capture interface, scalable core frequencies, USB On-the-Go
(OTG), full SDIO support, and an Intel coprocessor. The coprocessor extends the Intel XScale®
microarchitecture capabilities by adding MMX and SSE functionality and additional audio and
video processing operations.
1.1 System Overview
The kit provides access to most of the Intel®PXA270 Processor native input/output (I/O)
functions. The kit kit consists of:
•Intel®PXA27x Processor Developer’s Kit Main Board (main board), which contains
peripheral and expansion capability to aid in application software development
•Intel®PXA27x Processor Developer’s Kit Daughter Card (daughter card), which can either
dock with the main board or operate independently
•Intel®PXA27x Processor Card (processor card), which is a board to allow for field upgrades
to the kit system as new steppings of silicon arrive.
•Intel®PXA27x Processor Developer’s Kit Power Manager Integrated Circuit (Low DropOut)
Card (PMIC card) card, which supplies all the various power domains for the system
•Intel®PXA27x Processor Developer’s Kit UCB1400 Audio Module (audio module), which
allows for the changing of audio CODECs depending on system usage.
•AC-to-DC power supply
•Hinged, fold-out user-interface panel containing the following:
— LCD panel
— touch screen
— matrix keypad and scroll wheel
— microphone and speaker
— video camera
•Mounting chassis that integrates all kit components into a compact, accessible package

Hardware Description 2
This chapter describes the Intel®PXA27x Processor Developer’s Kit (kit) hardware.
•Section 2.1 — User-Interface Panel
•Section 2.2 — Intel® PXA27x Processor Developer’s Kit Main Board
The Intel®PXA27x Processor Developer’s Kit Main Board (main board) serves as the
docking station for an Intel®PXA27x Processor Developer’s Kit Daughter Card (daughter
card) to make it easier for you to develope many different types of applications. The main
board features peripheral devices, sockets for various expansion cards, extensive input/output
(I/O) capability, and user-interface aids.
•Section 2.3 — Intel® PXA27x Processor Developer’s Kit Daughter Card
The daughter card contains the Intel®PXA27x Processor Card (processor card), memory,
nominal I/O capability, and the required power circuitry Intel®PXA27x Processor
Developer’s Kit Power Manager Integrated Circuit (Low DropOut) Card (PMIC card) for two
modes of operation:
— When docked with the main board, the daughter card provides a complete development
and evaluation system.
— In self-contained (stand-alone) mode, the daughter card can boot and function
independently of the main board, although without the extensive I/O capability furnished
by the main board.
•Section 2.4 — Intel® PXA27x Processor Card
•Section 2.5 — Power Management
Figure 1 shows an overview of the kit.

Figure 1. Intel®PXA27x Processor Developer’s Kit Overview
Note: Figure 1 does not show the camera module.
The instructions in this chapter and in Chapter 3, “Programming Guide” provide enough details to
start operating with minimal effort. In most cases, however, the optimal use of a device requires
detailed reference to the device manufacturer’s data sheet. To locate this information, refer to
Table 1, “Supplemental Documentation” on page 8.
Using this kit effectively requires a sound knowledge of the Intel XScale®technology and the
Intel®Micro Signal Architecture baseband processor. Refer to the Intel®PXA27x Processor
Family Developer’s Manual for items related to the applications processor.
Note: Most of the switches on the main board are SPDT slide switches with one of the positions
identified by a DOT. Switch positions are thus indicated as DOT or NO DOT. The switches on the
daughter card are DIP switches and are indicated as ON or OFF.
2.1 User-Interface Panel
The user-interface panel, shown in Figure 1, contains the following items:
•LCD Panel
The liquid-crystal display panel is mounted on an adapter board, which slides in and out of the
user-interface panel for operation in either landscape or portrait orientation. (Figure 1 shows
the LCD Panel in landscape orientation.) There is a separate connector for each orientation.
The LCD Panel connects from J2 on the keypad card to J17 on the main board by a ribbon
cable. For more information, see Section 2.2.6.

Note: The “2” in J12 was inadvertently left off during the silkscreening of J12, causing it to appear as
“J1” in Circuit Revision 2.1 of the main board. J1 is the processor USB Client connector and is
located near the covered J4 USB host 0 connector, while J12 is a reserved USB Client connector,
and is located near the J13 USB On the Go (OTG) connector. While the J13 connector is visible,
the J13 silkscreening is covered with components and may be difficult to locate. Use Figure 4 to
locate these connectors.
