1.3.2 Main Board
1.3.2.1 CPU : Intel PXA255, 300MHz
The PXA255 applications processors provide high integration, high performance and low power consumption for
portable handheld and handset devices. These applications processors incorporate Intel’s XScaleTM
Microarchitecture based on the ARM* V5TE architecture. The applications processor’s memory interface supports
a variety of memory types that allow flexibility in design requirements. Hooks for connection to two companion
chips permit glueless connection to external devices. An integrated LCD display controller provides support for
displays, and permits 1, 2 and 4 bit grayscale and 8 or 16 bit color pixels. A 256-byte palette RAM provides
flexibility in color mapping. A rich set of serial devices as well as general system resources provide enough
compute and connectivity capability for many applications. For details on the programming model and theory of
operation of each of these units, refer to the Intel® PXA255 and PXA210 Applications Processors Developer's
Manual.

1.3.2.5 Audio Amplifier : TI TPA0253
Description
The TPA0253 is a 1-W mono bridge-tied-load (BTL) amplifier designed to drive speakers with as low as 8Ω
impedance. The mono signal is created by summing left and right inputs internally. The amplifier can be
reconfigured on-the-fly to drive two stereo single-ended (SE) signals into head phones. This makes the device ideal
for use in small notebook computers, PDAs, digital personal audio players, anyplace a mono speaker and stereo
head phones are required. From a 5V supply, the TPA0253 can delivery 1W of power into a 8Ω speaker.
The gain of the input stage is set by the user-selected input resistor and a 50kΩ internal feedback resistor (AC=RF/RI). The power stage is internally configured with a gain of –1.25V/V in SE mode, and –2.5V/V in BTL mode.
Thus, the overall gain of the amplifier is 62.5kΩ/RI in SE mode and 125kΩ/RI in BTL mode. The input terminals
are high-impedance CMOS inputs, and can be used as summing nodes. The TPA0253 is available in the 10-pin
thermally-enhanced MSOP package (DGQ) and operates over an ambient temperature range of -40 ºC to 85 ºC .
Features :
Ideal for Notebook Computers, PDA , and Other Small Portable Audio Devices

1.3.2.7 UART Transceiver : SIPEX SP3243E
Description
The SP3223E and 3243E products are RS-232 transceiver solutions intended for portable of hand-held applications
such as notebook and palmtop computers. The SP3223E and 3243E use an internal high-efficiency, charge-pump
power supply that requires only 0.1mF capacitors in 3.3V operation. This charge pump and Sipex’s driver
architecture allow the SP3223E/3243E series to deliver compliant RS-232 performance from a single power supply
ranging from +3.3V to +5.0V. The SP3223E is a 2-driver/2-receiver, and the SP3243E is a 3-driver/5-receiver
device ideal for laptop/notebook computer and PDA applications.
The SP3243E includes one complementary receiver that remains alert to monitor an external device’s Ring Indicate
signal while the device is shutdown. The Auto-Online feature allows the device to automatically “wake-up” during
a shutdown state when an RS-232 cable is connected and a connected peripheral is turned on. Otherwise, the device
automatically shuts itself down drawing less than 1mA.
Features :
Meets true EIA/TIA-232-F standards from a +3.0V to +5.5V power supply
Interoperable with EIA/TIA-232 and adheres to EIA/TIA-562 down to a +2.7V power source
Auto-Online circuitry automatically wakes up from a 1mA shutdown
