CS5464
1. OVERVIEW
The CS5464 is a CMOS monolithic power measurement device with a computation engine and an ener-
gy-to-frequency pulse output. The CS5464 combines two programmable gain amplifiers, three ∆Σ ana-
log-to-digital converters (ADCs), system calibration, and a computation engine on a single chip.
The CS5464 is designed for power measurement applications and is optimized to interface to a cur-
rent-sense resistor or transformer for current measurement, and to a resistive divider or potential trans-
former for voltage measurement. The current channels provide programmable gains to accommodate
various input levels from a multitude of sensing elements. The second current channel is designated for
tamper detection support in applications where required. With a single +5 V supply on VA+/AGND, the
CS5464’s three input channels can accommodate common mode plus signal levels between
(AGND - 0.25 V) and VA+.
The CS5464 also is equipped with a computation engine that calculates instantaneous power, IRMS,
VRMS, apparent power, active (real) power, reactive power, and power factor. Additional features of the
CS5464 include line frequency, current and voltage sag detection, zero-cross detection, positive-only ac-
cumulation mode, and three programmable pulse output pins. To facilitate communication to a micropro-
cessor, the CS5464 includes a simple three-wire serial interface which is SPI™ and Microwire™
compatible. The CS5464 provides three outputs for energy registration. Pins E1, E2, and E3 are designed
to interface to a microprocessor.

SWITCHING CHARACTERISTICS
• Min / Max characteristics and specifications are guaranteed over all Recommended Operating Conditions.
• Typical characteristics and specifications are measured at nominal supply voltages and TA = 25 °C.
• VA+ = 5 V ±5% VD+ = 3.3 V ±5% or 5 V ±5%; AGND = DGND = 0 V. All voltages with respect to 0 V.
• Logic Levels: Logic 0 = 0 V, Logic 1 = VD+.
