2001-2012 microchip technology inc. 3.0 detailed description 3.1 functional description the tc74 acquires and converts temperature information from its onboard solid-state sensor with a resolution of 1c. it stores the data in an internal register which is then read through the serial port. the system interface is a slave smbus/i 2 c port, through which temperature data can be read at any time. eight smbus/i 2 c addresses are programmable for the tc74, which allows for a multi-sensor configuration. also, there is low power standby mode when temperature acquisition is suspended. 3.1.1 standby mode the host is allowed, by the tc74, to put it into a low power (i dd = 5 a, typical) standby mode. in this mode, the a/d converter is halted and the temperature data registers are frozen. the smbus/i 2 c port, though, operates normally. standby mode is enabled by setting the shdn bit in the config register. table 3-1 summarizes this operation. table 3-1: standby mode operation 3.1.2 smbus/i 2 c slave address the tc74 is internally programmed to have a default smbus/i 2 c address value of 1001 101b . seven other addresses are available by custom order (contact microchip technology inc. 3.2 serial port operation the serial clock input (sclk) and bidirectional data port (sda) form a 2-wire bidirectional serial port for pro- gramming and interrogating the tc74. the conventions used in this bus architecture are listed in table 3-2. table 3-2: serial bus conventions all transfers take place under the control of a host, usu- ally a cpu or microcontroller, acting as the master. this host provides the clock signal for all transfers. the tc74 always operates as a slave. the serial protocol is illustrated in figure 3-1. all data transfers have two phases and all bytes are transferred msb first. accesses are initiated by a start condition, followed by a device address byte and one or more data bytes. the device address byte includes a read/write selec- tion bit. each access must be terminated by a stop condition. a convention called acknowledge (ack) confirms receipt of each byte. note that sda can change only during periods when sclk is low (sda changes while sclk is high are reserved for start and stop conditions). shdn bit operating mode 0 normal 1 standby term explanation transmitter the device sending data to the bus. receiver the device receiving data from the bus. master the device which controls the bus initi- ating transfers (start), generating the clock and terminating transfers (stop). slave the device addressed by the master. start a unique condition signaling the begin- ning of a transfer indicated by sda falling (high-low) while sclk is high. stop a unique condition signaling the end of a transfer indicated by sda rising (low- high) while sclk is high. ack a receiver acknowledges the receipt of each byte with this unique condition. the receiver drives sda low during sclk high of the ack clock-pulse. the master provides the clock pulse for the ack cycle. busy communication is not possible because the bus is in use. not busy when the bus is idle, both sda and sclk will remain high. data valid the state of sda must remain stable during the high period of sclk in order for a data bit to be considered valid. sda only changes state while sclk is low during normal data transfers (see start and stop conditions). downloaded from: http:/// ? 2001-2012 microchip technology inc. ds21462d-page 7 tc74 figure 3-1: smbus/i 2 c protocols. 3.3 start condition (s) the tc74 continuously monitors the sda and sclk lines for a start condition (a high-to-low transition of sda while sclk is high) and will not respond until this condition is met. 3.4 address byte immediately following the start condition, the host must transmit the address byte to the tc74. the states of a2, a1 and a0 determine the smbus/i 2 c address for the tc74. the 7-bit address transmitted in the serial bit stream must match for the tc74 to respond with an acknowledge (indicating the tc74 is on the bus and ready to accept data). the 8-bit in the address byte is a read/write bit. this bit is a 1 for a read operation or 0 for a write operation. during the first phase of any transfer, this bit will be set = 0, indicating that the command byte is being written. 3.5 acknowledge (ack) acknowledge (ack) provides a positive handshake between the host and the tc74. the host releases sda after transmitting 8 bits. the host then generates a ninth clock cycle to allow the tc74 to pull the sda line low. this action acknowledges that the tc74 successfully received the previous 8 bits of data or address. 3.6 data byte after a successful ack of the address byte, the host must transmit the data byte to be written, or clock-in the data to be read (see the appropriate timing diagrams). ack will be generated upon a successful write of a data byte into the tc74. 3.7 stop condition (p) communications must be terminated by a stop condition (a low-to-high transition of sda while sclk is high). the stop condition must be communicated by the transmitter to the tc74. refer to figure 1-1, timing diagrams, for serial bus timing. s address wr ack command ack data ack p 8 bits 7 bits 8 bits slave address command byte: selects which register you are writing to. data byte: data goes into the register set by the command byte. write byte format read byte format s address wr ack command ack s address rd ack data nack p 7 bits 8 bits 7 bits 8 bits slave address command byte: selects which register you are reading from. slave address: repeated due to change in data- flow direction. data byte: reads from the register set by the command byte. receive byte format s address rd ack data nack p 7 bits 8 bits data byte: reads data from the register commanded by the last read byte or write byte transmission. s = start condition p = stop condition shaded = slave transmission downloaded from: http:/// tc74 ds21462d-page 8 ?
