System Plus Consulting is proud to publish the reverse costing report of the MEMS Tire Pressure Monitoring System (TPMS) MPXY8300A supplied by Freescale Semiconductor. Based on a complete teardown process the report provides an estimation of the production cost as well as the selling price of the circuit.

This Freescale MPXY8300A TPMS component is used in cars, trucks or buses to detect under-inflated or over-inflated tires. It uses a Multi-Chip Package containing 4 separate dies : 2 capacitive MEMS devices (pressure sensor, 2-axis accelerometer with X and Z axis) and 2 Integrated Circuits (8-bit microcontroller, radio frequency transmitter).

This report provides complete teardown and cost estimation of the component with :

  • Material analysis
  • Schematic assembly description
  • Manufacturing Process Flow
  • In-depth economical analysis
  • Manufacturing cost breakdown
  • Selling price estimation
