AN238 Tire Pressure Monitoring (TPM) System

www.DataSheet4U.com AN238 Tire Pressure Monitoring (TPM) System Authors: Ruan Lourens Microchip Technology Inc. Curtis Kell Kell Laboratories An auto-location system can dynamically detect the position of a specific sensor, which is useful when tires are rotated. The heart of the TPM system is the Sensor/Transmitter (S/TX) device and it is based on Microchip's rfPIC12F675. INTRODUCTION This document explains a typical tire pressure monitoring (TPM) system specifically intended for automotive u.

AN238 Features

* an internal RC oscillator, thereby reducing the external component count which, directly reduces module cost as well as circuit board size. Third, this device includes the RF transmitter circuitry, which again reduces external component count, cost and overall size of the circuit board. The rfPIC12F
