1323x-Modular Reference Board
1323x Development Hardware Reference Manual, Rev. 1.0
Freescale Semiconductor 3-5
3.2 Functional Description
The 1323x-MRB is built around Freescale’s MC1323x 48-pin LGA IEEE 802.15.4 platform. Figure 3-2
shows a simple block diagram. This board is intended as a simple evaluation platform and as a building
block for application development. The 4-layer board provides the MC1323x with its required RF
circuitry, 32 Mhz reference oscillator crystal, and power supply bypassing. The layout for this base level
functionality can be used as a reference layout by the user target board.
In additional to the base MC1323x functionality, the 1323x-MRB provides features to assist in debug, an
IR blaster, a 2 Mbit serial FLASH, reset button, simple power manager, and expansion connectors for the
GPIO. In the following sections, refer to:
• Figure 3-1 for location of connectors and features
• Figure 3-3 for the functional blocks
• Figure 3-11 for the board schematic
