5 / 26 page Test Point Headers TP1 to TP4 10-Pin SM-DIG Connector I C Interface 2 TMP102 J1 4 www.ti.com TMP102EVM Hardware Setup 2.1 Theory of Operation for TMP102 Hardware The TMP102EVM only requires the two-wire I 2C lines (SDA and SCLK) and V DUT/GND to supply a constant 3.3 V and power return, as shown in Figure 3. The TMP102EVM also has test points to monitor these signal lines and ground, in case users may want to use their own signals or verify successful I 2C communications. Figure 3. TMP102EVM Board Block Diagram 2.2 Signal Definitions of H1 (10-Pin Male Connector Socket) Table 3 shows the pinout for the 10-pin connector socket used to communicate between the TMP102EVM and the SM-USB-DIG. It should be noted that the TMP102EVM uses only the necessary I 2C communication lines (pins 1 and 3) and the V DUT and GND (pins 6 and 8, respectively) to issue commands to the TMP102 sensors. Table 3. Signal Definition of H1 on TMP102EVM Board Pin on U1 Signal Description 1 I2C_SCL I 2C Clock Signal (SCL) 2 CTRL/MEAS4 GPIO: Control Output or Measure Input 3 I2C_SDA1 I 2C Data Signal (SDA) 4 CTRL/MEAS5 GPIO: Control Output or Measure Input 5 SPI_DOUT1 SPI Data Output (MOSI) 6 V DUT 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 (MISO) (1) When V DUT is Hi-Z, all digital I/O are Hi-Z as well. 5 SBOU114 – August 2011 TMP102EVM Evaluation Board and Software Tutorial Submit Documentation Feedback Copyright © 2011, Texas Instruments Incorporated |
