SoC
V9801S/V9811S
Ultralow Power 1-Phase Energy Metering SoC
The V9811S and V9801S are single-phase energy metering SoC chips, featuring very low power dissipation and
high performance. They integrate the analog front end (AFE), Vango proprietary metering technology VMA
(Vango Metering Architecture), enhanced 8052 MCU core, real-time clock (RTC), Flash memory, LCD driver and
WDT. They are ideally suitable for single-phase multi-functional energy meter applications. Both devices are
RoHS compliant.
To improve the reliability, Vango proprietary VMA uses dedicated hardwired circuits instead of software to
process signals for active and reactive power and energy, apparent power and RMS calculations. The metering
accuracy exceeds the requirements of IEC standards. The VMA supports RMS and power gain calibrations,
power offset correction and phase compensation. The calibration can be speeded up when low current is
applied.
To ensure the system stability, the V9801S and V9811S supervise the crystal oscillator and replace it with the
integrated RC oscillator when the crystal stops running. Both devices can generate interrupt when leakage is
detected in the external capacitors for the reference voltage generation circuit. Both devices provide
configurable wakeup with reset.

V9271/V9281
1-Phase Energy Metering AFE with UART Interface
The V9281 and V9271 are high accuracy, single-phase energy metering AFE chips, featuring ultralow power
dissipation and high performance. Both devices are RoHS compliant.
Both the V9281 and V9271 support 3 analog inputs, 2 for current and 1 for voltage. The V9281 has additional
3 analog inputs: 1 pair of differential inputs suitable for magnetic field measurement and 2 single-end inputs
for DC signal measurement. Both devices incorporate 3 oversampling Σ/Δ ADCs, the reference circuit, and
Vango proprietary metering technology VMA (Vango Metering Architecture) which uses dedicated hardwired
circuits instead of software to process signals for total (fundamental and harmonic) and fundamental-only
active and reactive power and energy and RMS calculations. The metering accuracy exceeds the requirements
of IEC standards. The VMA supports RMS and power gain calibrations, power offset correction and phase
compensation. The calibration can be speeded up when low current is applied.
Both the V9281 and V9271 integrate Vango patented UART interface (vUART) that enables them to
communicate with isolated MCU using only 2 opto-couplers rather than typical 4 opto-couplers, which reduces
the system cost significantly.

V9260
Ultralow Power 1-Phase Power Measurement AFE
The V9260 is a high accuracy, single-phase power measurement AFE chip, featuring the world’s lowest power
dissipation. This device is RoHS compliant.
The V9260 supports 2 analog inputs for current and voltage. The device incorporates 2 oversampling Σ/Δ
ADCs, the reference circuit, and Vango proprietary metering technology VMA (Vango Metering Architecture)
which uses dedicated hardwired circuits instead of software to process signals for total (fundamental and
harmonic) and fundamental-only active and reactive power and RMS calculations. The metering accuracy
exceeds the requirements of IEC standards. The VMA supports RMS and power gain calibrations, power offset
correction and phase compensation.
The V9260 integrates Vango patented UART interface (vUART) that enables it to communicate with isolated
MCU using only 2 opto-couplers rather than typical 4 opto-couplers, which reduces the system cost
significantly.
The low power feature of the V9260 enables it to be used with a capacitor divider power supply network
featuring higher reliability and lower cost. Employing the V9260 together with shunt resistors, a 3-phase
energy meter can have better performance and lower cost due to the absence of current transformers.

Vango Product Brief
AFE
V9203
3-Phase Energy Metering AFE
The V9203 is a high accuracy, 3-phase energy metering AFE chip. Its active energy metering dynamic range is
world’s widest, 10000:1, with metering error less than 0.1%. This device is RoHS compliant.
The V9203 has 7 analog inputs, 3 for phase current, 1 for neutral current, and 3 for phase voltage. It
incorporates 7 oversampling Σ/Δ ADCs, the reference circuit, and Vango proprietary metering technology VMA
(Vango Metering Architecture) which uses dedicated hardwired circuits instead of software to process signals
for total (fundamental and harmonic) and fundamental-only active, reactive and apparent power and energy
and RMS calculations of each phase and on the overall system. The metering accuracy exceeds the
requirements of IEC standards. The VMA supports RMS and power gain calibrations and offset corrections, and
phase compensation in segments. The digital integrators in the current paths enable easy use of the Rogowski
coil sensors for current analog inputs.
The V9203 has an SPI interface to communicate with the MCU and a serial interface for direct access to ADC
outputs. The device incorporates 4 pins to output pulses proportional to energy, 3 voltage direction pins to
help detect the phase sequence, and 2 interrupt pins to indicate that the enabled interrupt events have
occurred.
The V9203 incorporates circuits to supervise power quality, such as zero-crossing, current detection, line
voltage period measurement, phase angle measurement and neutral current mismatch detection.

RS-485
V6601
Polarity Self Adaptive RS-485 Transceiver
with Internal Pull-Up and Pull-Down Resistors
The V6601 is an RS-485 transceiver featuring half-duplex, low power dissipation, reduced-slew-rate, polarity
detection and self-adaption, and compliant with EIA/TIA-485 protocol. This device is RoHS compliant.
The V6601 integrates one driver and one receiver, both enabled independently. When both driver and receiver
outputs are disabled, the device outputs high impedance. The V6601 has high driving capability, which allows
up to 256 drivers on the bus. The driver features reduced-slew-rate, which can minimize EMI and reduce
reflections caused by improperly terminated cables, and guarantee error-free data transition with data rate up
to 500kbps.
The supply voltage range for the V6601 is 4.5~5.5V. In the shutdown mode, the supply current is less than
1μA.
The V6601 is protected from faults due to shorted or open receiver input, over-thermal, over-current, and
overvoltage, and it features polarity detection and self-adaption, which can eradicate connection failure due
to mis-wiring.
