ConnectCore 9M 2443 & Wi-9M 2443 Hardware Reference
In addition to the on-module wired Ethernet interface, the ConnectCore Wi-9M 2443
module also provides an integrated 802.11a/b/g WLAN interface. The WLAN interface
is based on the Digi WM500ABG baseband processor and specifically designed for
embedded products with long-term product availability requirements.
The WM500ABG is connected to the S3C2443 processor via the external 16 bit data
bus and RCS4#. To write to the WM500ABG the software has to latch the most
significant word by writing at addr+1 and then write the LSW to adr. The onboard
logic provides a 32 bit cycle to the WM500ABG when addr is accessed. To read the
WM500ABG the software has to read at addr and then read the latched MSW at
addr+1.
The WLAN baseband controller can be reset through GPB3. When this signal is low,
the baseband controller is in reset mode. When high, the controller is active. The
interrupt signal connected to the baseband controller is EINT_15.
Note: Please use HIROSE U.FL-LP-N-2 extraction tool for removing an U.FL cable from
the ConnectCore Wi-9M 2443.
The 10-bit /10-channels CMOS ADC (Analog to Digital Converter) converts the analog
input signal into 10-bit binary digital codes at a maximum conversion rate of 500KSPS
with 2.5MHz A/D converter clock. A/D converter operates with on-chip sample-and-
hold function and power down mode is supported.
The touch screen Interface can control/select pads (ConnectCore 9M 2443, XP, XM,
YP, YM) of the Touch Screen for X, Y position conversion. The touch Screen Interface
provides Touch Screen Pads control logic and ADC interface logic with interrupt
generation.
