hcla series miniature amplified low pressure sensors 8/15 e / 11629 / f www.first-sensor.com www.sensortechnics.com i2c bus introduction the hcla is capable to generate a digital output signal. the device runs a cyclic program, which will store a corrected pressure value with 12 bit resolution about every 250 s within the output registers of the internal asic. in order to use the sensor for digital signal readout, it should be connected to a bidirectional i2c-bus. according to the i2c-bus specification, the bus is controlled by a master device, which generates the clock signal, controls the bus access and generates start and stop conditions. the hcla is designed to work as a slave, hence it will only respond to requests from a master device. digital i2c interface the hcla complies with the following protocol (fig. 1): bus not busy : during idle periods both data line (sda) and clock line (scl) remain high. start condition (s) : high to low transition of sda line while clock (scl) is high is interpreted as start con- dition. start conditions are always generated by the master. each initial request for a pressure value has to begin with a start condition. stop condition (p) : low to high transition of sda line while clock (scl) is high determines stop condition. stop conditions are always generated by the master. more than one request for the current pressure value can be trans- mitted without generation of intermediate stop condition. data valid (d) : state of data line represents valid data when, after start condition, data line is stable for duration of high period of clock signal. data on line must be changed during low period of clock signal. there is one clock pulse per bit of data. acknowledge (a) : data is transferred in pieces of 8 bits (1 byte) on serial bus, msb first. after each byte receiving device ? whether master or slave ? is obliged to pull data line low as acknowledge for reception of data. master must generate an extra clock pulse for this pur- pose. when acknowledge is missed, slave transmitter becomes inactive. it is on master either to send last com- mand again or to generate stop condition in that case. slave address : the i2c-bus master-slave concept requires a unique address for each device. the hcla has a preconfigured slave address (1111000xb). by factory programming it is possible to define a secondary slave address additional to the general one. according to i2c specification 127 different addresses are available. the sensor will then listen to both slave addresses. after generating a start condition the master sends the address byte containing a 7 bit address followed by a data direction bit (r/w). a "0" indicates a transmission from master to slave (write), a "1" indicates a data request (read). data operation : the sensor starts to send 2 data bytes containing the current pressure value as a 15 bit information placed in the output registers. sda scl start condition data valid data allowed to change stop condition r/w read out of first pressure value read out of n pressure values (optional) s data byte 1 a data byte 2 slave address a 1 a p data byte 1 generated by master generated by slave s = start condition a = acknowledge p = stop condition data byte 1 = high byte (msb first) data byte 2 = low byte (lsb last) fig. 1: i2c bus protocol
