Single-Phase
AC Power Measurement IC
DATA SHEET
DS_6613_018
DESCRIPTION
The Teridian™ 78M6613 is a highly integrated IC for
simplified implementation of single-phase AC power
measurement into power supplies, smart appliances, and
other applications with embedded AC load monitoring and
control. It is packaged in a small, 5mm x 5mm, 32-pin QFN
package for optimal space savings.
At the measurement interface, the device provides four
analog inputs for interfacing to voltage and current sensors.
Voltages from the sensors are fed to our Single Converter
Technology® that uses a 22-bit delta-sigma ADC,
independent 32-bit compute engine (CE), digital
temperature compensation, and precision voltage
references to provide better than 0.5% power measurement
accuracy over a wide 2000:1 dynamic range.
The integrated MPU core and 32 KB of flash memory
provides a flexible means of configuration, post-processing,
data formatting, and interfacing to any host processor
through the UART interface and/or DIO pins. Complete
application firmware is available and can be preloaded into
the IC during manufacturing test. Alternatively, a complete
array of ICE, development tools, and programming libraries
are available to allow customization for each application.

Hardware Description
Hardware Overview
The Teridian 78M6613 single-chip measurement unit integrates all primary functional blocks required to
embed solid-state AC power and energy measurement. Included on chip are:
An analog front end (AFE)
An independent digital computation engine (CE)
An 8051-compatible microprocessor (MPU) which executes one instruction per clock cycle (80515)
A voltage reference
A temperature sensor
RAM and Flash memory
A variety of I/O pins
Current sensor technologies supported include Current Transformers (CT) and Resistive Shunts.
In a typical application, the 32-bit compute engine (CE) of the 78M6613 sequentially processes the
samples from the voltage inputs on pins A0, A1, A2, A3 and performs calculations to measure active
2
2
energy (Wh), reactive energy (VARh), A h, and V h for four-quadrant measurement. These
measurements are then accessed by the MPU, processed further and output using the peripheral
interfaces available to the MPU.
In addition to the temperature-trimmed ultra-precision voltage reference, the on-chip digital temperature
compensation mechanism includes a temperature sensor and associated controls for correction of
unwanted temperature effects on measurement. Temperature dependent external components such as
crystal oscillator, current transformers (CTs), and their corresponding signal conditioning circuits can be
characterized and their correction factors can be programmed to produce measurements with
exceptional accuracy over the industrial temperature range, if desired.
A block diagram of the IC is shown in
Figure 1.
A detailed description of various functional blocks
