In partnership with X-FAB Silicon Foundries SE, Chinese automotive electronics chip design company AutoChips Inc. announced it has initiated the volume production of an advanced Tire Pressure Monitoring System (TPMS) chipset.

Fully designed in-house by AutoChips, the automotive-grade AC5111 chipset is being manufactured at X-FAB’s state-of-the-art MEMS facility, in Erfurt, Germany. The MEMS-based chipset has already received orders in the tens of thousands of pieces, the two companies claim.

Studies have shown that 70% of highway traffic accidents in China are caused by tire punctures. When the air pressure of the tire is 10% lower than the normal value, its lifespan is reduced by 15% to 20%, and vehicle fuel consumption per kWh increases by 260ml. Based on these figures, China’s Standardization Administration has made it mandatory for all vehicles built from January 2020 onwards to incorporate TPMS technology.
The AC5111 chipset integrates six functional elements - including an enhanced low power consumption microcontroller, a pressure sensor, temperature sensor and an accelerometer, as well as Radio Frequency (RF) and Low Frequency (LF) functions. It is China’s first self-designed, full-feature, single-chip TPMS solution to reach mass production.
AutoChips’ next-generation TPMS chipset is already under development, along with a series of other product innovations.
