NXP NTM88 Pressure Sensor

NXP NTM88 Pressure Sensor
The NXP NTM88 pressure sensor is a complete, fully integrated tire pressure monitoring sensor solution in a single compact package. the NTM88 TPMS solution integrates an 8-bit microcontroller (MCU), pressure sensor, accelerometer, and RF transmitter. The device features low transmit power consumption, large customer memory size, and a choice of dual-axis or single-axis accelerometer architectures.
The NXP Semiconductors NTM88 pressure sensor is available in a compact 4.0mm x 4.0mm HQFN24 package with notched wettable flanks for visible solder joint inspection.
