SLDS171 – NOVEMBER 2009
System Configuration/Programming
See the "Baud Rate Settings" table (Table 21).
Programming Voltage
Internally generated programming voltage
Only active during the write mode
The programming voltage can be monitored at PROGV pin.
15-ms sec timer / internal undervoltage comparator to guarantee required programming time and voltage
level. (12.5 V, 15 ms + system response time > 20 ms)
Temperature Sensor
Output data linearly proportional to temperature.
Internal Oscillator
2.458 MHz
External resistor is used for current reference
10 k
Sensor Output
Input signal from sensor is analog/digitally processed and output 10-bit word via DIO
Linear region: output is linear to the sensor input. Clamp region: output is at the clamp value.
Output and DIAG data can be requested every 100 ms.
Refer to Data format communications between microprocessor to IC Mode selection (microprocessor
→ IC)
chart.
Data Transfer Format
See Table 16.
Data Output Request (Sensor vs Calibration Mode)
Sensor Mode
1. Receive sensor position ID
2. Output pressure or temperature + DIAG + MODE information
Calibration Mode
A data access mode can be selected by setting ACSUNT
Bank Mode (ACSUNT = 1)
1. Receive sensor position ID + command
2. Receive Bank address
3. Available output is: 1. Sensor output + diagnostics, 2. Temperature, 3. ADC output, 4. Configuration baud
rate, 5. Sensor ID + Position ID, 6. Over-pressure setting, 7. Calibration setting, 8 Temperature data, 9.
Over-pressure setting history, 10. Calibration history, 11. Mode data
Field Mode (ACSUNT = 0)
1. Receive sensor position ID + Command
2. Receive Field address
3. Available output is: 1. Sensor + diagnostics, 2. Temperature, 3. ADC output, 4. Mode data
