4.1.2 System Temperature Compensation
In a production electricity meter, the 71M6533 and 71M6534 is not the only component contributing to
temperature dependency. A whole range of components (e.g. current transformers, resistor dividers,
power sources, filter capacitors) will contribute temperature effects.
Since the output of the on-chip temperature sensor is accessible to the MPU, temperature compensation
mechanisms with great flexibility are possible. MPU access to GAIN_ADJ permits a system-wide temperature
correction over the entire meter rather than local to the chip.
4.1.3 Temperature Compensation for the RTC
In order to obtain accurate readings from the RTC, the following calibration procedures are recommended:
1. At the time of meter calibration, the crystal oscillator may be calibrated using the RTCA_ADJ register in
I/O RAM to be as close to 32768 Hz as possible. The recommended procedure is to connect a high-
precision frequency counter to the TMUXOUT pin and select 0x11 for TMUX[4:0]. This will generate a
4-second pulse at TMUXOUT that can be used to trim RTCA_ADJ to the best value.
A wider trim range is achieved with the I/O RAM registers PREG[16:0] and QREG[1:0].
2. When the meter is in service, the MPU takes frequent temperature readings. If the temperature
characteristics of the crystal are known, the temperature readings can be used to modify the settings
for the I/O RAM registers PREG[16:0] and QREG[1:0] in order to keep the crystal frequency close to
32768 Hz.
3. After periods of operation under battery power, the temperature for the time the meter was not powered
can be estimated by averaging the temperatures before and after battery operation. Based on this,
the overall correction for the RTC time can be calculated and applied to the RTC after main power returns
to the meter.
4.2 Connecting LCDs
The 71M6533 and 71M6534 have an on-chip LCD controller capable of controlling static or multiplexed
LCDs. Figure 36 shows the basic connection for an LCD.
The following dedicated and multi-use pins can be assigned as LCD segments:
15 dedicated LCD segment pins: SEG0 to SEG2, SEG8, SEG12 to SEG18, SEG20 to SEG23.
9 dual-function pins: MUX_SYNC/SEG7, CKTEST/SEG19, E_RXTX/SEG9, E_TCLK/SEG10,
E_RST/SEG11, SEG3/PCLK, SEG4/PSDO, SEG5/PCSZ, SEG6/PSDI.
5 additional dual-function pins in the 71M6534: SEG51/E_TBUS0, SEG52/E_TBUS1,
SEG53/E_TBUS2, SEG54/E_TBUS3, SEG55/E_ISYNC
33 (71M6533) or 46 (71M6534) combined DIO and segment pins
o 71M6533: SEG24/DIO4 to SEG31/DIO11, SEG33/DIO13 to SEG41/DIO21, SEG43/DIO23 to
SEG47/DIO27, SEG49/DIO29, SEG50/DIO30, SEG61/DIO41, SEG63/DIO43 to
SEG65/DIO45, and SEG67/DIO47 to SEG71/DIO51.
o 71M6534: SEG24/DIO4 to SEG50/DIO30, SEG56/DIO36 to SEG59/DIO39, SEG61/DIO41 to
SEG75/DIO55.
