The Freescale MPXY8040A is an 8-pin tire pressure monitoring sensor which is comprised of a variable capacitance pressure sensor element, a temperature sensing element, and an interface circuit (with a wake-up feature) all on a single chip. It is housed in a Super Small Outline Package (SSOP), which includes a media protection filter. Specifically designed for the low power consumption requirements of tire pressure monitoring systems, it can combine with a Freescale remote keyless entry (RKE) system to facilitate a low-cost highly integrated system.
