2.2 Signal Definitions of H1 (10-Pin Connector Socket)

Table 2-1 lists the pinout for the 10-pin connector socket used to communicate between the INA233EVM and the SM-USB-DIG. It should be noted that the INA233EVM only uses the necessary I2C communication lines (pins 1 and 3) and the VS and GND pins (pin 6 and pin 8) to issue commands to the INA233 chip.

Table 2-1 Signal Definition of J4 on INA233EVM Board
Pin on J4 Signal Description
1 I2C_SCL I2C Clock Signal (SCL)
2 CTRL/MEAS4 GPIO: Control Output or Measure Input
3 I2C_SDA1 I2C Data Signal (SDA)
4 CTRL/MEAS5 GPIO: Control Output or Measure Input
5 SPI_DOUT1 SPI Data Output (PICO)
6 VDUT Switchable DUT Power Supply: +3.3 V, +5 V, Hi-Z (Disconnected)(1)
7 SPI_CLK SPI Clock Signal (SCLK)
8 GND Power Return (GND)
9 SPI_CS1 SPI Chip Select Signal ( CS)
10 SPI_DIN1 SPI Data Input (POCI)
(1) When VDUT is Hi-Z, all digital I/O are Hi-Z as well.
