Data on line must be changed during LOW period of clock signal. There is one clock pulse per bit of data. 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 µs 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. 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 purpose. When acknowledge is missed, slave transmitter becomes inactive. It is on master either to send last command again or to generate STOP condition in that case. 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 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). 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 condition. 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 transmitted without generation of intermediate STOP condition. 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. SCL SDA START condition Data valid 1 S Slave Address R/W A Data allowed to change Data Byte 1 A STOP condition Data Byte 2 Read out of first pressure value generated by master generated by slave A Data Byte 1 P Read out of n pressure values (optional) S = START condition Data Byte 1 = High Byte (MSB first) A = Acknowledge Data Byte 2 = Low Byte (LSB last) P = STOP condition Fig. 1: I²C bus protocol E / 11629 / F 8/15 www.first-sensor.com www.sensortechnics.com HCLA Series Miniature amplified low pressure sensors I²C Interface Parameters Parameter Symbol Input high level Input low level Output low level Pull-up resistor Load capacitance @ SDA Input capacitance @ SDA/SCL SCL clock frequency Bus free time between STOP and START condition Hold time (repeated) START condition, to first clock pulse LOW period of SCL HIGH period of SCL Setup time repeated START condition Data hold time Data setup time Rise time of both SDA and SCL Fall time of both SDA and SCL Setup time for STOP condition Min.
