9 / 23 page TMP103 www.ti.com SBOS545A – FEBRUARY 2011 – REVISED MARCH 2011 Table 7. THIGH Register ONE-SHOT (M1 = '0', M0 = '1') D7 D6 D5 D4 D3 D2 D1 D0 The TMP103 features a One-Shot Temperature H7 H6 H5 H4 H3 H2 H1 H0 Measurement mode. When the device is in Shutdown mode, writing a '01' to bits M1 and M0 starts a single temperature conversion. During the conversion, bits Table 8. TLOW Register M1 and M0 read '01'. The device returns to the D7 D6 D5 D4 D3 D2 D1 D0 shutdown state at the completion of the single L7 L6 L5 L4 L3 L2 L1 L0 conversion. After the conversion, bits M1 and M0 read '00'. This feature is useful for reducing power consumption in the TMP103 when continuous BUS OVERVIEW temperature monitoring is not required. The device that initiates the transfer is called a As a result of the short conversion time, the TMP103 master, and the devices controlled by the master are can achieve a higher conversion rate. A single slaves. The bus must be controlled by a master conversion typically takes 26ms and a read can take device that generates the serial clock (SCL), controls place in less than 20 μs. When using One-Shot mode, the bus access, and generates the START and STOP 30 or more conversions per second are possible. conditions. To address a specific device, a START condition is CONTINUOUS CONVERSION MODE (M1 = '1') initiated, indicated by pulling the data line (SDA) from When the TMP103 is in Continuous Conversion mode a high to low logic level while SCL is high. All slaves (M1 = '1'), a single conversion is performed at a rate on the bus shift in the slave address byte on the determined by the conversion rate bits, CR1 and CR0 rising edge of the clock, with the last bit indicating (in the Configuration Register). The TMP103 whether a read or write operation is intended. During performs a single conversion and then powers down the ninth clock pulse, the slave being addressed and waits for the appropriate delay set by CR1 and responds to the master by generating an CR0. See Table 6 for CR1 and CR0 settings. Acknowledge and pulling SDA low. Data transfer is then initiated and sent over eight TEMPERATURE LIMIT REGISTERS clock pulses followed by an Acknowledge Bit. During The THIGH and TLOW registers are used to store the data transfer, SDA must remain stable while SCL is temperature limit thresholds for the TMP103 high, because any change in SDA while SCL is high watchdog function. At the end of each temperature is interpreted as a START or STOP signal. measurement, the TMP103 compares the Once all data have been transferred, the master temperature results to each of these limits. If the generates a STOP condition indicated by pulling SDA temperature result is greater than the THIGH limit, then from low to high, while SCL is high. the FH bit in the configuration register is set to '1'. If the temperature result is less than the TLOW limit, then SERIAL INTERFACE the FL bit in the configuration register is set to '1'; see Figure 8. The TMP103 operates as a slave device only on the two-wire bus and SMBus. Connections to the bus are Table 7 and Table 8 describe the format for the THIGH made via the open-drain I/O lines SDA and SCL. The and TLOW registers. Power-up reset values for THIGH SDA and SCL pins feature integrated spike and TLOW are: THIGH = +60°C and TLOW = –10°C. The suppression filters and Schmitt triggers to minimize format of the data for THIGH and TLOW is the same as the effects of input spikes and bus noise. The for the Temperature Register. TMP103 supports the transmission protocol for both fast (1kHz to 400kHz) and high-speed (1kHz to 3.4MHz) modes. All data bytes are transmitted MSB first.
