Figure 2 Tire module circuit The tire module circuit uses FREESCALE's intelligent embedded sensor MPXY8300. This series of sensors integrates the company's low-power S08 core, contains 512 bytes of RAM and 16 KB Flash, and also integrates low-power capacitive pressure and temperature Sensor and single-channel low-frequency input interface. Its RF transmission supports two carrier frequencies of 315 MHz and 434 MHz, and can be programmed to make the register be amplitude shift keying (ASK) or frequency shift keying (FSK) modulation. It also integrates the charge pump function. When the battery voltage is low, it can increase the power supply voltage of the RF transmission part, so that it can still achieve a certain RF transmission intensity. MPXY8300 is a system-on-chip (SOC) that integrates a pressure and temperature sensor, an 8-bit microcontroller (MCU), an RF transmitter, and a dual-axis (XY) accelerator all on one chip. MPXY8300 Pressure measurement range: 100 ~ 800 kPa for cars, 100 ~ 1 400 kPa for trucks, and temperature measurement range: -40 ~ 125 ℃.
