It is a 5MHz 8051 compatible microcontroller core of Teridian's 71M6541D/71M6541F/71M6541G/71M6542F/71M6542G™ 4th generation single-phase metering SoC, low-power RTC with digital temperature compensation, flash memory, LCD driver. Our single-converter technology with 22-bit Δ-ΣADC, three or four analog inputs, digital temperature compensation, precision voltage reference, 32-bit calculation engine (CE) ® supports a wide range of metrology applications with minimal external components.
The 71M6541/2 device supports optional interfaces with Teridian's 71M6x01 series isolation sensors, providing BOM cost reduction, immunomagnetic tamper-proofing, and enhanced reliability. Other features include an SPI interface, advanced power management, ultra-low power operation in active and battery modes, 3/5KB shared RAM and 32/64/128KB flash memory for field programming with code and/or data instrumentation operation and drivability SEG driver pins during every six LCD segments. High processing and sampling rates combined with differential inputs provide a powerful metering platform for residential meters.
A complete set of code development tools, demonstration codes, reference designs, to meet all ANSI and IEC energy metering standards in the world rapid development and certification.
