DIGITAL OUTPUT Solid State Pressure SensorCCD Series - Model 54D FEATURES • DIP or SMD Package • Calibrated Span and Offset • Multi-order Temperature compensation • OWI, I2C or SPI Interface • 3V or 5V Supply • Customized Configuration upon request DESCRIPTION The Series CCD Model 54D is a smart pressure transducer with digital output via 1-wire serial, I2C or SPI interface. Digital compensation of sensor offset, sensitivity, temperature drift and nonlinearity is accomplished in factory via an internal DSP running a correction algorithm with calibration coefficients stored in on-chip EEPROM. A variety of characteristic configuration, including accuracy, sampling rate, temperature compensated range are available to provide simple and ready-to-use solution for a wide rage of application. It can be operated in supply voltage of 2.7 to 5.5 V, and can be extended to 30V with an external JFET. The Series CCD is available for pressure range from 0.15 psi to 150 psi. Special configuration as low as 2.5 mbar is also applicable. Please contact factory for detail. Competitive sensor & power supply solutions worldwide PEWATRON

Communication Interface Manchester codes by a transition at the cell boundary are used to represent the binary values of pressure and temperature. Bit Encoding Data Cell 50% duty cycle used to set up strobe time Read Operation There are two modes (DPT digital pressure output with temperature, and DTO digital pressure out only) available for the output of transducer. For DPO mode, the transducer first transmits the high byte of pressure data followed by the low byte. The pressure data is 14-bits in resolution, so the upper two bits of the high byte are always zero padded. There is a half...

Timing The baud rate (transmission frequency) of the Manchester coded bit stream is determined during factory calibration and depends on the update rate and thus response time that the customer specifies for the transducer. If no response time is specified by the customer the default response time of 5ms (200Hz) will be selected. There are a total of 4 different update rates listed below. Using the two faster update rates will result in the baud rate being 32kHz and the two slower update rates will result in the baud rate being set to 8kHz. Hints for Writing Firmware: The Baud rates (8kHz...
