STPM34TR Description

The STPM34TR is a high-precision Analog Front End (AFE) for DC and AC energy measurement, with great accuracy down to extremely low current, as seen in stand-by appliances. The STPM34TR metering ic has a high level of system integration and allows for on-chip power quality monitoring.
Up to four independent 24 bit 2nd order ADCs with PGA are included in the STPM34TR IC. The STPM34TR includes an inbuilt DSP for calculating "turn-key" energy parameters. Built-in temperature corrected dual voltage references and programmable double LED output for active and reactive energy pulse creation.


STPM34TR Features

<0.1% error over 5000: 1 dynamic range
<0.5% error over 10000: 1 dynamic range
Exceeds 50-60 Hz EN 50470-x, IEC 62053-2x, ANSI12.2x standard requirements for AC watt meters
Reactive power accuracy:
<0.1% error over 2000:1 dynamic range
Dual mode apparent energy calculation
Instantaneous and averaged power
RMS and instantaneous voltage and current
Under and overvoltage detection (sag and swell) and monitoring
Overcurrent detection and monitoring
UART and SPI serial interface with programmable CRC polynomial verification
Programmable LED and interrupt outputs
Four independent 24-bit 2ndorder sigma-delta ADCs
Two programmable gain chopper stabilized low-noise and low-offset amplifiers
Bandwidth 3.6 kHz @ -3 dB
Vccsupply range 3.3 V±10%
Supply current Icc4 mA (STPM32)
Input clock frequency 16 MHz, Xtal or external source
Twin precision voltage reference: 1.18 V with independent programmable TC, 10 ppm/°C typ.
Internal low drop regulator @ 3 V (typ.)
QFN packages
Operating temperature -40 °C~+85 °C
