The The TMP103 resets the serial interface if SCL is held master must issue an acknowledge for each byte low for 30ms (typ). The TMP103 releases the bus if it read in order to read all of the TMP103 devices on is pulled low and waits for a START condition. To the bus; see Figure 15. If the master does not avoid activating the timeout function, it is necessary acknowledge each byte of data, the TMP103s stop to maintain a communication speed of at least 1kHz sending subsequent data for any remaining devices. for SCL operating frequency. Up to eight TMP103 devices can be on the same bus and respond to MDA commands; see Table 9. MULTIPLE DEVICE ACCESS NOTE: If the bus contains an incomplete sequence of The TMP103 supports Multiple Device Access TMP103 device addresses, the master must transmit (MDA), which allows the master to communicate with all required dummy bytes for the missing device multiple TMP103 devices on the same bus interface address to allow for normal MDA read operation. For with one interface transaction. MDA commands example, if the TMP103A, TMP103B, and TMP103D consist of an MDA read address (00000001) and an devices are on the bus, the master must transmit an MDA write address (00000000). The device MDA read address followed by four bytes and four acknowledges the MDA address and responds to the acknowledges in order to complete the MDA read command accordingly. In order for MDA to function transaction. correctly, different product versions of the TMP103 must be used in the system; see Table 9. NOISE Multiple Device Access Write The TMP103 is a very low-power device and The master transmits an MDA write address followed generates very low noise on the supply bus. Applying by the pointer address of the register to be accessed; an RC filter to the V+ pin of the TMP103 can further see Table 2. Following the pointer, all of the TMP103 reduce any noise the TMP103 might propagate to devices on the bus acknowledge and wait for the next other components. RF in Figure 10 should be less byte of data to be written to the addressed registers. than 5k Ω and CF should be greater than 10nF. When the data byte is received by the TMP103 devices, they store and acknowledge the transmitted byte. The TMP103s store the same data on all devices on the bus in one transaction; see Figure 14. Multiple Device Access Read Note that before an MDA read transaction can begin, the master must first send an MDA write transaction in order to set the appropriate pointer address of the register to be accessed, as stated in the previous section. The master can then transmit an MDA read address followed by a read byte for each TMP103 used on the bus. For example, if a TMP103A and TMP103B are used on the same bus and an MDA read address is sent, the address must be followed Figure 10. Noise Reduction by two bytes of data and two master acknowledges. Copyright © 2011, Texas Instruments Incorporated Submit Documentation Feedback 11 Product Folder Link(s): TMP103 |
