 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-
