GENERAL DESCRIPTION

The ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/

1

ADE7569

integrate the Analog Devices, Inc., energy (ADE) metering IC analog front end and fixed function DSP solution with an enhanced 8052 MCU core, an RTC, an LCD driver, and all the peripherals to make an electronic energy meter with an LCD display in a single part.

The ADE measurement core includes active, reactive, and apparent energy calculations, as well as voltage and current rms measurements. This information is accessible for energy billing by using the built-in energy scalars. Many power line supervisory features such as SAG, peak, and zero crossing are included in the energy measurement DSP to simplify energy meter design.

FUNCTIONAL BLOCK DIAGRAMS

The microprocessor functionality includes a single-cycle 8052 core, a real-time clock with a power supply backup pin, an SPI

2

or I

C® interface, and a UART interface. The ready-to-use information from the ADE core reduces the program memory size requirement, making it easy to integrate complicated design into 16 kB of flash memory.

The ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/ ADE7569 also include a 108-/104-segment LCD driver. In the ADE7166/ADE7169/ADE7566/ADE7569, this driver generates voltages capable of driving LCDs up to 5 V.

In the ADE7166/ADE7169, this pin can be either an analog input when the LCD resistor driver is enabled or an analog output when the LCD charge pump is enabled. In the ADE7116/ADE7156, this pin is always an analog input. When this pin is an analog output, it should be decoupled with a 470 nF capacitor. When this pin is an analog input, it is internally connected to V

. A resistor should be connected between this pin and

16 LCDVP2

In the ADE7166/ADE7169, this pin can be either an analog input when the LCD resistor driver is enabled or an analog output when the LCD charge pump is enabled. In the ADE7116 and ADE7156, this pin is always an analog input. When this pin is an analog output, a 100 nF capacitor should be connected between this pin and LCDVP1. When this pin is an analog input, it is internally connected to LCDVP1 (see the LCD Driver section).

17 LCDVB

In the ADE7166/ADE7169, this pin can be either an analog input when the LCD resistor driver is enabled or an analog output when the LCD charge pump is enabled. In the ADE7116/ADE7156, this pin is always an analog input. When this pin is an analog output, it should be decoupled with a 470 nF capacitor. When this pin is an analog input, a resistor should be connected between this pin and LCDVC to generate an intermediate voltage for the LCD driver. In 1/3 bias LCD mode, another resistor must be connected between this pin and LCDVA to generate another intermediate voltage. In 1/2 bias LCD mode, LCDVB and LCDVA are internally connected (see the LCD Driver section).

TERMINOLOGY

Measurement Error

The error associated with the energy measurement made by the ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/ADE7569 is defined by the following formula:

Percentage Error =

⎛ ⎜

⎜ ⎝

Phase Error Between Channels

The digital integrator and the high-pass filter (HPF) in the current channel have a nonideal phase response. To offset this phase response and equalize the phase response between channels, two phase correction networks are placed in the current channel: one for the digital integrator and the other for the HPF. The phase correction networks correct the phase response of the corresponding component and ensure a phase match between current channel and voltage channel to within ±0.1° over a range of 45 Hz to 65 Hz with the digital integrator off. With the digital integrator on, the phase is corrected to within ±0.4° over a range of 45 Hz to 65 Hz.

Power Supply Rejection (PSR)

PSR quantifies the ADE7116/ADE7156/ADE7166/ADE7169/ ADE7566/ADE7569 measurement error as a percentage of reading when the power supplies are varied. For the ac PSR measurement, a reading at nominal supplies (3.3 V) is taken. A second reading is obtained with the same input signal levels when an ac (100 mV rms/120 Hz) signal is introduced onto the supplies. Any error introduced by this ac signal is expressed as a percentage of reading (see the Measurement Error definition).

−

EnergyTrue

⎞

EnergyTrueRegisterEnergy

⎟

⎟ ⎠

(1)

%100×

For the dc PSR measurement, a reading at nominal supplies (3.3 V) is taken. A second reading is obtained with the same input signal levels when the supplies are varied ±5%. Any error introduced is again expressed as a percentage of the reading.

ADC Offset Error

ADC offset error is the dc offset associated with the analog inputs to the ADCs. It means that, with the analog inputs connected to AGND, the ADCs still see a dc analog input signal. The magnitude of the offset depends on the gain and input range selection (see the Typi ca l Per f o r ma n c e Characteristics section). However, when HPF1 is switched on, the offset is removed from the current channel, and the power calculation is not affected by this offset. The offsets can be removed by performing an offset calibration (see the Analog Inputs section).

Gain Error

Gain error is the difference between the measured ADC output code (minus the offset) and the ideal output code (see the Current Channel ADC section and Voltage Channel ADC section). It is measured for each of the gain settings on the current channel (1, 2, 4, 8, and 16). The difference is expressed as a percentage of the ideal code.

and manages power supply failures. The power management functionalities can be accessed directly through the 8052 SFRs (see Tabl e 16 ).

Writing to the Interrupt Pins Configuration SFR (INTPR, Address 0xFF)

To protect the RTC from runaway code, a key must be written to the key SFR (KYREG, Address 0xC1) to obtain write access to INTPR. KYREG (see Table 126) should be set to 0xEA to unlock this SFR and reset to 0 after a timekeeping register is written to. The RTC registers can be written using the following 8052 assembly code:

MOV KYREG, #0EAh MOV INTPR, #080h
