Electricity Meter
Electricity Meters measure the kilowatt hours consumed, the power factor
of the load and the time of the electricity consumption to support multi-
rate metering. The communications system in these meters requires
reliability and range, which Silicon Labs provides with its EZRadioPRO
embedded wireless transceivers, C8051F900 MCUs, Si84xx digital
isolators and CP2400 LCD Controllers.

EZMac
®
Embedded Media Access Control Software
EZMac
®
media access control module is developed in C code for use with
our ISM transceiver products and MCUs to create very low cost mesh
networks. EZMac software provides designers a simplified interface to the
physical radio layer that manages signal delivery and associated packets
from the transmitter to the receiver and between nodes.
• Supports ISM band transceivers
• Internal baud rate generator
• 16 byte payload per packet
ELECTRICITY METER
• Dedicated crystal oscillator for exact timing
Utility
• DQD (data quality detector) for FSK fast frequency hopping
Communication Subsystem

The Wireless Development Suite
(WDS) provides developers a
comprehensive toolset to quickly
and easily create and deploy
efficient, robust and low-cost
wireless applications. WDS can
be used for demonstrating part
capabilities, testing performance,
and prototyping application
examples, with little or no
RF design and measurement
experience.
