Hardware details
Metering IC U1
The programmable single-phase energy metering IC STPM01BTR (package: TSSOP20) is
interfaced to a microcontroller using a 3-wire SPI interface. Active energy, apparent energy,
instantaneous voltage, and instantaneous current values are obtained from the STPM
metering IC. Auto-calibration is implemented to calibrate the STPM.
Clocking Y1
A 4.194 MHz crystal is used as the clock generator input for the metering IC. For more
details about auto-calibration, please refer to
Microcontroller U2
The microcontroller STM8l152C6 (package: LQFP48, 32K Flash, 2KB RAM, 48-pin) is
responsible for all the data management and power management tasks. MCU consumes
very lower power and has an in-built RTC for date and time management.
LED D10
LED D10 is the pulse out LED for cumulative energy. This is used for testing the energy
meter energy calculation accuracy.
Switch SW1 and SW2
Switch SW1 is the reset switch for the microcontroller. Switch SW2 is the case tamper
switch which is used to detect case tampering of energy meter solution.
For more details, refer to
Jumper J2
Table 1.
Clocking Y2
A 32.768 kHz crystal is used as the clock input for LSE (low speed external) for the
microcontroller RTC block. The microcontroller core is clocked by a HSI (high speed
internal) clock.
