DESCRIPTION
The SAMES SA2005P provides a single chip active energy
metering solution for three phase mechanical counter-based
meter designs.
Th SA2005P does not require any external trim-pots or resistor
ladders for meter calibration. Calibration and meter
configuration information is stored on a small external
EEPROM.
Meter setup stored on the EEPROM includes various metering
direction modes (total sum, absolute sum, positive or negative
energy) phase calibration data, rated metering conditions,
LED pulse rate, counter pulse width, counter resolution and
creep current.
A programmable rate pulse output is available for meter
calibration purposes. Per phase voltage fail and voltage
sequence faults as well as energy direction indication are
available as LED outputs. Programmable dividers enable
various mechanical counter or stepper motor counter
resolutions.
A precision oscillator, that replaces an external crystal, is
integrated on chip. A voltage reference is integrated on chip.
The SA2005P integrated circuit is available in 24-pin dual in
line plastic (DIP-24) and small outline (SOIC-24) package
options.

PIN DESCRIPTION
PIN Designation Description
20
GND
Analog Ground. The voltage to this pin should be mid-way between VDD and VSS.
6 VDD Positive supply voltage. Typically +5V if a current transformer is used for current sensing.
18 VSS Negative supply voltage. Typically 0V if a current transformer is used for current sensing.
21, 24, IVN1, IVN2, Voltage sense inputs. The current into the A/D converter should be set at 14µARMS at nominal mains

voltage. The voltage sense input saturates at an input current of ±25µA peak.
23, 22,
2, 1,
5, 4
IIN1, IIP1,
IIN2, IIP2,
IIN3, IIP3
Inputs for current sensors. The termination resistor voltage from each current transformer is
converted to a current of 16µARMS at rated conditions. The current sense input saturates at an input
current of ±25µA peak.
19 VREF This pin provides the connection for the reference current setting resistor. A 24kW resistor
connected to VSS sets the optimum operating condition.
8 SCL Serial clock output. This output is used to strobe data from the external EEPROM.
9
SDA
Serial data. Send and receive data from an external EEPROM.
17
TEST
Test input. For normal operation connect this pin to VSS.
10 LED Calibration LED output. Refer to section Led Output (LED) for the pulse rate output options.
11, 12 MON, MOP Motor pulse outputs. These outputs can be used to drive an impulse counter or stepper motor directly.
13 PH / DIR
7 RLOAD
14, 15, PH1, PH2,

Triggers a data reload from the external EEPROM.
Multiplexed LED drivers for direction and mains fail indication.
