78M6610+PSU Data Sheet
1.3
Analog Front-End and Conversion
250 ????
The Analog Front-End (AFE) of the 78M6610+PSU includes an input multiplexer, delta-sigma A/D
converter, bias current references, voltage references, temperature sensor, and several voltage fault
comparators.
Delta-Sigma A/D Converter
A second-order delta-sigma converter digitizes the analog inputs. The converted data is then processed
through an FIR filter.
Voltage Reference
The device includes an on-chip precision bandgap voltage reference that incorporates auto-zero
techniques as well as production trims to minimize errors caused by component mismatch and drift. The
voltage reference is digitally compensated over temperature.
Die Temperature Measurement
The device includes an on-chip die temperature sensor used for digital compensation of the voltage
reference. It is also used to report temperature information to the user.
Voltage and Current Inputs
The external voltage and current sensors are connected to differential voltage input pins. The full-scale
signal level that can be applied to the voltage input pins is V 3P3A ±250 mV. Considering a sinusoidal
waveform, the maximum RMS voltage is:
VrmsMAX = √ 2 = 176.78mV
Although the voltage input is differential, a common-mode voltage of less than ±25 mV is recommended
in order to utilize the available dynamic range.
Temperature Inputs
ATEMP1 and ATEMP2 are single-ended inputs that allow temperature measurement through an external
sensing element (NTC, RTD etc.). The temperature measurement is generally used to monitor heat-sink
or exhaust air operating conditions. TEMP2 is only available with the 24-pin package option.
1.4
24-Bit Energy Measurement Processor (EMP)
The 78M6610+PSU integrates a dedicated 24-bit signal processor that performs all the digital signal
processing necessary for energy measurement, alarm generation, calibration, compensation, etc. Refer
to Section 2 for a description of functionality and operations.
1.5
Flash and RAM
The 78M6610+PSU includes 8KB of on-chip flash memory. The flash memory primarily contains program
code, but also stores coefficients, calibration data, and configuration settings. The 78M6610+PSU
includes 1.5KB of on-chip RAM which contains the values of input and output registers and is utilized by
the FW for its operations.
1.6
Communication Peripherals
The 78M6610+PSU includes three communication interface options: UART, SPI, and I C.
2
Since the I/O pins are shared, only one mode is supported at a time. Two pins are sampled at power-on
or reset to determine which interface will be active.
