GENERAL DESCRIPTION
The 71M6515H is a high-accuracy analog front-end
(AFE) IC that provides measurements for 3-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-precision
reference, and a compute engine results in high
accuracy and wide dynamic range. Our 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 multipurpose
pins are provided for control of peripherals.
