The board requires power and I 2C™ communication with the SM-USB-DIG. This configuration allows the TMP104EVM software to communicate with the SM-USB-DIG and the TMP104 Test Board. In addition, test points allow for application-specific connections to be used on the TMP104 Test Board. Figure 3. TMP104EVM 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 TMP104EVM and the SM-USB-DIG. It should be noted that the TMP104EVM 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 TMP104. Table 3. H1 Signal Definition for TMP104EVM Pin on U1 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 (MOSI) Switchable DUT power supply: +3.3 V, +5 V, 6 VDUT 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. 4 TMP104EVM Evaluation Board and Software Tutorial SBOU118 – October 2011 Submit Documentation Feedback Copyright © 2011, Texas Instruments Incorporated |
