    Regardless of the calibration procedure used, parameters (calibration constants) will result that will have to be applied to the 71M6521 chip in order to make the chip apply the modified gains and phase shifts necessary for accurate operation. Table 1-11 shows the names of the calibration constants, their function, and their location in the CE RAM.

The 6521BE Demo Code does not need these parameters, since it does not display voltage and current RMS values on the LCD. If necessary, the user can derive the values for register variables that depend on VMAX and IMAX by multi- plying the count in the registers with the LSB values given in Table 1-17.

  • Page 53: Calibration Procedures

    It is essential for a valid meter calibration to have the voltage stabilized a few seconds before the current is applied. This enables the Demo Code to initialize the 71M6521 and to stabilize the PLLs and filters in the CE. This method of operation is consistent with meter applications in the field as well as with metering standards.

    The calibration procedures described below should be followed after interfacing the voltage and current sensors to the 71M6521 chip. When properly interfaced, the V3P3 power supply is connected to the meter neutral and is the DC reference for each input. Each voltage and current waveform, as seen by the 6521, is scaled to be less than 250mV (peak).

A pull-up resistor of roughly 3kΩ to V3P3 should be used for the DI/DO signals, and the CS pin should be pulled down with a resistor to prevent that the three-wire device is selected on power-up, before the 71M6521 can establish a stable signal for CS.

These pins allow the TFP-2 to reset the 71M6521 chip after a flash erase operation using the watchdog- timeout mechanism, allowing flash memory parts with the SECURE bit set (see the data sheet for more information) to be erased and reprogrammed.

    71M6521 Demo Board User’s Manual D6521T4A10: FEATURES 3.4.1 D6521T4A10 FEATURE SUMMARY The features added to the D6521T4A10 Demo Board are: Circuitry was added that supports features required for the India market. J14 was removed. The 6-pin header J15 is the only programming connector available on the board. An adapter that enables the transition from the AMP/Tyco connector used for the ADM51 ICE or for the TFP2 programmer to the 6-pin header J15 is supplied with the Demo Kit.

    71M6521 Demo Board User’s Manual 3.4.2 D6521T4A10 FEATURES FOR THE INDIA MARKET Several India-specific features were added to the D6521T4A10 Demo Board to support the detection of tamper attempts. These features are: A 2-pin header (TP1) is provided that allows the connection of a “neutral-missing” transformer. This transformer normally provides enough output voltage and current to supply the Demo Board in case the main AC supply is disconnected.
