The NPX1 sensor represents the next-generation Remote Tire Pressure Monitoring (RTPM). NPX1 sensor adds a silicon pressure sensor, a 8-bit RISC processor, and a LF-input stage to meet market demands for flexible, customer specific behavior/solutions and overall system cost reduction.

This programmable version of the sensor is available for development purposes, allowing the customer to download the application code in an electrically programmable ROM version. This sensor is intended for developing the application specific program. In order to ensure high reliability, the NPX1 sensor has the measurement routines (pressure, temperature, and supply voltage) implemented in ROM.
