DESCRIPTION
The SAMES SA9122E Single Phase
unidirectional active Power/Energy metering
integrated circuit includes a seperate on-
chip 64 segment Liquid Crystal Display driver.
The power/energy metering circuit generates
a pulse rate output, proportional to the power
consumption, while the LCD driver is
programmable via a serial interface.
The method of power calculation takes the
power factor into account. Energy consump-
tion is determined by the power measurement
being integrated over time.
The LCD driver is capable of driving 8 decimal
digits (7 segment) and 8 announciators on a
4 track multiplexed backplane display.
This innovative combination energy metering/
LCD display driver integrated circuit has
been designed to provide meter designers
with flexibility in the choice of the μ-controller
employed, and is ideally suited for applica-
tions such as residential municipal metering
and factory energy metering and control.
The SA9122E integrated circuit is available
in both 40 pin dual-in-line plastic (DIP-40), as
well as 44 pin plastic leaded chip carrier
(PLCC-44) package types.
