- With the addition of two new AFE types, for single-phase and multi-phase energy measurement of microchips
1~8 Channel MCP391X Product Family Lineup Completed

Seoul, November 6, 2014 – Microchip Technology (Korea Representative: Byung-Don Han), a global leader in microcontrollers, analog semiconductors, and flash-IP solutions, has launched the MCP391X energy measurement analog front-end (AFE) family of high-precision, 1 to 8-channel single-phase and poly-phase products.

The new MCP3919 and MCP3912 products incorporate 3-channel and 4-channel 24-bit delta-sigma analog-to-digital converter (ADC) capabilities, featuring industry-leading precision of 93.5 dB SINAD, -107 dB THD, and 112 dB SFDR, respectively, for accurate signal acquisition and superior end products. These channel counts are optimized for single-phase energy meters (3 channels) or single-phase 3-wire energy meters (4 channels) with neutral monitoring capabilities. This highly integrated new AFE also includes a low-drift voltage reference, a programmable gain amplifier, phase delay compensation, and a cycle redundancy check (CRC).

As energy metering infrastructure is upgraded globally, there is an increasing demand for AFE accuracy and integration for the development of modern smart meters. Developers of advanced power monitoring systems also require high accuracy and integration for applications in industrial, commercial, and consumer markets, such as server power supplies and power distribution units (PDUs), electronic circuit breakers, smart power strips, and other data acquisition products. Microchip's latest AFE enhances application performance through industry-leading accuracy, high integration, and a channel count optimized for single-phase energy measurement. In addition, the high accuracy of AFE
Production costs are reduced as energy meters can be calibrated using the bath.

Bryan J. Liddiard, Vice President of Marketing for Microchip’s Analog and Interface Products business unit, stated, "With this new energy measurement AFE, Microchip’s high-precision product family lineup is complete," adding, "Developers can now apply a single source to all single-phase or multi-phase applications."

Development support
Microchip announced two new tools to help develop energy systems using the latest AFE: the MCP3912 evaluation board (part number ADM00499) and the MCP3919 evaluation board (part number ADM00573).

supply
Both the MCP3912 and MCP3919 AFE are currently available for sample supply and mass production, and are provided in 28-pin QFN and SSOP packages in units of 5,000 each.
