4.2 Functional Description
The 1323x-RCM is a host motherboard for the 1323x-MRB. The two-board combination provides a
powerful evaluation and development platform for the MC13233. Figure 4-2 shows a simple block
diagram. The 4-layer board provides a flexible power supply, 36 pushbutton matrix, 128x32 LCD,
Touchpad sensor, 3-axis accelerometer, four indicator LEDs, buzzer, and a USB <> UART serial port.
As the board name implies this platform is useful to develop an RF remote control application for a DTV,
entertainment console, or similar function. The 1323x-MRB provides the RF node and an IR transmitter
is available to support legacy IR protocol remote controls. The rich set of peripherals of the 1323x-RCM
allows a user to develop a remote control ranging from a simple input device to a higher end unit with
display.
