DFZM-E72xx
IEEE802.15.4 System-On-Chip ZigBee Module
HIS DOCUMENT describes the DFZM-E72xx ZigBee module hardware specification. The EM357
based modules provide cost effective, low power, and flexible platform to add ZigBee connectivity
for embedded devices for a variety of applications, such as wireless sensors and energy monitoring. It
combines 32-bit ARM Cortex-M3 processor, in-system programable flash memory, 12-KB RAM,
192KB flash memory and off module certified antenna options, and various RF front end options for end
customer range needs in order to provide a ZigBee and regulatory certified. The module has various
operating modes, making it highly suit for system where ultralow power consumption is required. Short
transition times between operating modes further ensure low energy consumption.
