GENERAL DESCRIPTION
The 71M6515H is a high-accuracy analog front end
(AFE) IC that provides measurements for four-
quadrant 3-phase metering. The combination of a
21-bit sigma-delta A/D converter with a six-input
analog front end, a thermally compensated high pre-
cision reference and a compute engine results in
high accuracy and wide dynamic range. Patented
Single-Converter Technology™ reduces cross talk
and cost. This IC also provides RTC and battery
backup for time-of-use (TOU) metering.

Figure 1: Meter block diagram
As shown in the block diagram (Figure 1), the host
processor communicates with the 71M6515H
through a UART interface using the programmable
IRQZ interrupt. The 71M6515H calculates and accu-
mulates meter measurements for each accumulation
interval. A high-speed synchronous serial port (SSI)
is provided to facilitate high-end metering. Integrated
rectifying functions on the battery backup circuit
enable minimal external component usage and
minimum back-up current. Also, eight multi-purpose
pins are provided for control of peripherals.
