Overview
Freescale Semiconductor Product Specification MPXY8300 Rev 4, 05/2009 Tire Pressure Monitor Sensor Product Specification The MPXY8300 Series is a 20-pin sensor for use in applications that monitor tire pressure and temperature.
It contains the pressure, temperature and 2-axis accelerometer sensors, a microcontroller, and an RF output all within a single package.
The MPXY8300 Series is comprised of the following functions all within the same package.
Features • • • • • • Pressure sensor with signal interface to ADC10 Temperature sensor with signal interface to ADC10 Z- and X-axis accelerometers with signal interface to ADC10 Voltage reference measured by ADC10 4-channel, 10-bit analog-to-digital converter 8-bit MCU – S08 Core with SIM, interrupt and debug/monitor – 512 RAM – 8K FLASH (in addition to 8K providing factory firmware and trim data) – 32-byte, low power, parameter registers Internal 315/434 MHz RF transmitter – External crystal oscillator – PLL-based output with fractional-n divider – ASK and FSK modulation capability – Programmable data rate generator – Manchester or bi-phase data encoding – 128-bit RF data buffer with RTS/CTS handshake – Direct access to RF transmitter from MCU for unique formats – Supply voltage charge pump to compensate for cold batteries with selectable charge times (30, 60, 120 and 240 msec) Differential input LF detector/decoder 4 GPIO pins with optional pull-ups/pull-downs and wake-up interrupt Real Time Interrupt driven by LFO with interrupt intervals of 8, 16, 32, 64, 128, 256, 512 or 1024 msec Low power wake-up timer and periodic reset driven by LFO Watchdog time-out with selectable times and clock sources 2-channel general purpose timer/PWM module (TPM1) Internal oscillators – MCU bus clock of 0.
5, 1, 2 and 4 MHz (1, 2, 4 and 8 MHz HFO) – Charge pump clock of 10 MHz – Low frequency, low power time clock (LFO) with 1 msec period – Medium frequency, LFR decoder and sensor clock (MFO) of 8 μsec period Low voltage detection Norma...
