STPM11/12/13/14  
Single phase energy metering IC with pulsed output  
and digital calibration  
Feature summary  
Ripple free active energy pulsed output  
Direct stepper counter drivers  
Shunt, current transformer, Rogowsky coil  
sensors  
Live and neutral monitoring (STPM13/14)  
TSSOP20  
Easy and fast digital calibration at only one  
load point  
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.  
No-load, negative power and tamper indicators  
Integrated linear VREGS  
RC (STPM11/13) or crystal oscillator  
(STPM12/14)  
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.  
Support 50÷60 HZ - IEC62052-11, IEC62053-  
2X specification  
Less than 0.1% error  
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  
order ∑∆ A/D converter blocks, band gap
