AUTOMOTIVE TPMS
ICs for Tire-pressure Monitoring Systems
Atmel
offers highly integrated circuits for battery-powered sensor-gauge and base-station applications in
®
tire pressure monitoring systems (TPMS). The TPMS product portfolio includes a low-power Flash-micro-
controller RF-transmitter IC family to be used along with separate capacitive pressure or motion sensors,
plus a broad range of standalone RF-transmitter and LF-receiver ICs that can be combined with sepa-
rate microcontroller or smart sensor devices. These TPMS ICs are suitable for temperatures up to 125°C
(extended storage temperatures up to 175°C), and they provide outstanding low current consumption,
which helps the sensor gauges achieve 10-year longevity.
The TPMS portfolio also includes an innovative transparent RF receiver IC family with very fast switch-
ing times between RKE and TPMS signals. These ICs are capable of covering all physical functions
needed for combined TPMS/RKE systems. The polling mode and bit-check functions are carried out by
the fi rmware in a separate microcontroller device such as Atmel's LIN multichip module ATA6612 with
integrated AVR

- Page 2 About TPMS TPMS systems help to avoid accidents by warning the driver about status of the tires. TPMS is a vehicle- embedded system, which detects the tire pressure by analyzing the difference between the wheel speeds (indirect method) or by measuring both temperature and pressure (direct method).
