1 Product Description

1.1 Overview
The SP30T Tire Pressure Monitoring (TPM) Sensor represents Infineon’s high pressure range TPM sensor for SUV
and Truck application. The SP30T combines a high pressure range with a high level of integration by including a
microcontroller and LF-input stage to meet market demands for flexible, customer specific solutions and overall
system cost reduction.

The sensor design is based upon Infineon’s proprietary and patented solutions for high reliability measurements in
harsh automotive environments, with a predictable and stable quality in high volume applications.

The SP30T measures pressures up to 1600kPa, temperature, supply voltage and acceleration (optional), and by
integrating these functions with an ASIC in one package, Infineon has developed the ideal product for high pressure
TPM applications.

1.2 Features
• Integrated Sensors
o High pressure range
o Acceleration
o Temperature
o Voltage
• Integrated Peripherals
o Microcontroller
o On board EEPROM
o GPIOs
o ADC for signal conditioning
o 2x LF Receiver for triggering
• Measurement Ranges
o Pressure Sensor 100 to 1600 kPa
o Temperature Sensor -40 to +125°C
o Supply Voltage Sensor 2.1 to 3.6 V
o Acceleration Sensor -12 to 115 g
