TDK Semi Intros 71M6513H Power Meter System-on-Chip

TDK Semiconductor Corp. (Irvine, CA), a leader in mixed-signal communication semiconductors, unveiled its system-on-chip for industrial poly-phase power meters. The new TDK 71M6513H integrates a 21-bit, delta-sigma-delta converter; a 32-bit compute engine; MCU, RTC and LCD drivers; and ultra-precision voltage reference, and provides better than 0.1% accuracy with only a few low-cost, external components.

The 71M6513H can perform many standard and custom functions, including active energy, apparent energy, voltage rms, current rms, as well as waveform samples data for optional external processing. It consumes less than 30 mW in mission and 13 µW in battery modes, and it includes 64 KB of MCU program/data storage, 7KB RAM, RTC, 5 V LCD boost, 2+ UARTs, and an I2C interface.

Pricing for the new 71M6513H power meter IC starts at $4.95 in 10,000-unit quantities. The device can be produced in FLASH and ROM versions and is now available for sampling in a 100-pin epLQFP package.
