Energy-measurement Analog Front Ends offer high accuracy and integration for  single-phase smart meters and power monitoring
Two new AFEs complete Microchip's MCP391X family, which spans 1 to 8channel mem!ers for sin"lephase an# polyphase ener"y meas$rement 
New Delhi, 6 November !"# $NA%DA&' ()*+   Microchip Technology Inc., a leading provider of
microcontroller, mixed-signal, analog and Flash-IP solutions, has announced the completion of its high-
accuracy, 1-8 channel, single and poly-phase MP!"1# energy-measurement Analog Front End $ AFE % 
family. The ne& ()+./"/ and ()+./" mem'ers integrate three and four channels of ()-'it, delta-sigma
 *nalog-to-+igital onversion $*+%, respectively, &ith industry-leading accuracy of "!. d I/*+, -10 d
T2+ and 11( d F+3 for precise signal ac4uisition and higher-performing end products. These are the
optimal num'ers of channels for single-phase energy meters &ith neutral monitoring $!-channel%5 or single-
phase, three-&ire energy meters $)-channel%. The high level of integration on the ne& *F6s also includes a
lo&-drift voltage reference, programma'le gain amplifiers, phase-delay compensation and cycle redundancy
chec7 $3%.
 *s the energy-metering infrastructure is 'eing upgraded &orld&ide, designers are demanding
increased *F6 accuracy and integration to develop the latest generation of smart meters. These features are
also re4uired 'y the designers of advanced po&er-monitoring systems for applications such as server po&er
supplies and po&er distri'ution units, electronic circuit 'rea7ers, smart po&er strips and other data-
ac4uisition products in the industrial, commercial and consumer mar7ets. Microchips ne&est *F6s improve
application performance &ith their industry-leading accuracy, high integration and optimal num'er of
channels for single-phase energy measurement. *dditionally, the high *F6 accuracy facilitates energy-meter
cali'ration, &hich reduces production costs.
9These ne& energy-measurement *F6s complete our high-accuracy family,9 said ryan :. ;iddiard,
mar7eting vice president of Microchips *nalog and Interface Products +ivision. 9/o& designers have a
single source for any single-phase or poly-phase application.9
Development support
Microchip also announced t&o ne& tools to aid in the development of energy systems using these
latest *F6s, the ()+./" Evaluation 0oard $part < *+M00)""% and ()+./"/ Evaluation 0oard $part <
 *+M00!%.
Availability
The ()+./" and ()+./"/  *F6s are 'oth availa'le today for sampling and volume production,
each in ,000-unit 4uantities. oth *F6s are offered in (8-pin =F/ and >P pac7ages.
