MPXY8300B6U

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 interr...
