MPXY8020A

MPXY8040A

The Freescale Semiconductor MPXY8000 series sensor is an 8-pin tire

monitoring sensor which is comprised of a variable capacitance pressure

sensing 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 Semiconductor remote keyless entry

(RKE) system to facilitate a low-cost, highly integrated system.

MPXY8040A:

OPTIMIZED FOR 500 kPa – 900 kPa

Detailed Description

The block diagram of the MPXY8000 series sensor is shown in Figure 1. The

pressure sensor is a capacitive transducer constructed using surface

micromachining, the temperature sensor is constructed using a diffused

resistor, and the interface circuit is integrated onto the same die as the sensors

using a standard silicon CMOS process.

SUPER SMALL OUTLINE PACKAGE

CASE 1352-03

The conditioning of the pressure signal begins with a capacitance to voltage

conversion (C to V) followed by a switched capacitor amplifier. This amplifier

has adjustable offset and gain trimming. The offset and gain are factory

calibrated, with calibration values stored in the EEPROM trim register. This

amplifier also has temperature compensation circuits for both sensitivity and

offset, which also are factory adjusted using the EEPROM trim register.

PIN ASSIGNMENT

The pressure is monitored by a voltage comparator, which compares the

measured value against an 8-bit threshold adjusted by a serial input. By

adjusting the threshold and monitoring the state of the OUT pin the external

device can check whether a low-pressure threshold has been crossed, or

perform up to 8-bit A/D conversions.

The temperature is measured by a diffused resistor with a positive

temperature coefficient driven by a current source, thereby creating a voltage.

The room temperature value of this voltage is factory calibrated using the

EEPROM trim register. A two-channel multiplexer can route either the pressure

or temperature signal to a sampling capacitor that is monitored by a voltage

comparator with variable threshold adjust, providing a digital output for

temperature.

8-pin Super Small Outline Package (SSOP)

An internal low frequency, low power 5.4 kHz oscillator with a 14-stage

divider provides a periodic pulse to the OUT pin (divide by 16384 for 3 seconds).

This pulse can be used to wake up an external MCU to begin an interface with

the device. An additional 10-stage divider will provide a pulse every 52 minutes

which can be used to reset an external MCU.
