Description

20

REVP

Reverse Power Output Indicator. See the Reverse Power section. This pin can be configured to output a

range of alternative power quality signals (see the Alternative Output Functions section).

21

ZX_I

Current Channel Zero-Crossing Output Pin. See the Current Channel Zero Crossing section. This pin can be

configured to output a range of alternative power quality signals (see the Alternative Output Functions

section).

22

IRQ

Interrupt Output. See the ADE7953 Interrupts section.

23

CF1

Calibration Frequency Output 1.

24

CF2

Calibration Frequency Output 2.

25

SCLK

Serial Clock Input for the Serial Peripheral Interface. All serial communications are synchronized to the

clock (see the SPI Interface section). If using the I2C interface, this pin must be pulled high. If using the

UART interface, this pin must be pulled to ground.

26

MISO/SDA/Tx

Data Output for SPI Interface/Bidirectional Data Line for I2C Interface/Transmit Line for UART Interface.

27

MOSI/SCL/Rx

Data Input for SPI Interface/Serial Clock Input for I2C Interface/Receive Line for UART Interface.

28

CS

Chip Select for SPI Interface. This pin must be pulled high if using the I2C or UART interface.

EPAD

Exposed Pad. Create a similar pad on the PCB under the exposed pad. Solder the exposed pad to the pad

on the PCB to confer mechanical strength to the package. Do not connect the pads to AGND.
