1323x-Modular Reference Board
3.1 1323x-MRB Overview
The 1323x-Modular Reference Board (1323x-MRB) is an IEEE 802.15.4 compliant evaluation board
based on the Freescale MC1323x device. The 1323x-MRB provides a platform to evaluate the MC1323x
device, develop software and applications, and demonstrate IEEE 802.15.4 based networking capabilities.
The core device is accompanied by the 32 MHz reference oscillator crystal, RF circuitry including
antenna, and supporting circuitry.
This basic board is intended as the core module for MC1323x evaluation and application development and
can be used in the following modes:
• Simple standalone evaluation platform
• Daughtercard to the other MC1323x Development Platform boards (1323x-RCM or 1323x-REM)
• Daughtercard to an application specific motherboard.
