MC1321x 評估套件 (EVK)
This manual provides a detailed hardware description of the MC1321xEVK which consists of a 13213-Network Coordinator Board (13213-NCB) and a 13213-Sensor Reference Board (13213-SRB).
The functionality of the 13213-NCB and 13213-SRB boards is very similar. The primary difference between the two boards revolves around the peripheral circuits, not in the reference design itself.
The 13213-NCB and 13213-SRB provide all the necessary components to evaluate and use the MC1321x solution. The 13213-NCB and the 13213-SRB are built around the Freescale MC1321x family. The MC1321x family is Freescale’s second-generation ZigBee platform which incorporates a low power 2.4 GHz radio frequency transceiver and an 8-bit microcontroller into a single 9x9x1 mm 71-pin LGA package.
The 13213-NCB and the 13213-SRB are compliant with the following standards:
? FCC standard 47 CFR, part 15, section 15.247
? ETSI EN 300-328-1
? ETSI EN 300-328-2
