voltage reference, low drop voltage regulator. The
digital part is composed of a system control,
oscillator, hard wired DSP and interface for
calibration and configuration.
The calibration and configuration are done by
OTP cells, that can be programmed through a
serial interface. The configured bits are used for
testing, configuration and calibration purposes.
From two

output signals coming from the
analog section, a DSP unit computes the amount
of consumed active energy. The active energy is
available as a pulse frequency output and directly
driven by a stepper counter. In the STPM1X an
output signal with pulse frequency proportional to
energy is generated. This signal is used in the
calibration phase of the energy meter application
allowing a very easy approach. When the device
is fully configured and calibrated, a dedicated bit
of OTP block can be written permanently in order
to prevent accidental entry into test mode or
changing any configuration bit.
TSSOP20
Description
The STPM1x family is designed for effective
measurement of active energy in a power line
system using a Rogowski Coil, Current
Transformer and Shunt sensors. This device is
specifically designed to provide all the necessary
features to implement a single phase energy
meter without any other active component. The
STPM1x device family consists, essentially, of two
parts: the analog part and the digital part. The
former, is composed of a preamplifier and first
