2021年中国轮胎压力监测系统（TPMS）产业链及发展洞察

NTM88 devices are programmed by NXP at production only with trim coefficients. After an application is programmed in the NTM88, the firmware library version is stored in byte CODE F. Use the function TPMS_READ_ID to return the value. NXP does not program this byte at production so CODE F is empty when NTM88 devices are shipped.

This document describes the embedded firmware found in all derivatives of the FXTH87xx11 and FXTH87xx12 devices. The intended audience for this document is firmware architects, developers, coders and/ or testers working with the FXTH87xx11 and FXTH87xx12 devices. This document is divided into three sections: This introduction, a section describing global variables and standard formats used throughout the functions, and a third section describing each function.

The Kinetis family of microcontrollers include system security and flash protection features that can be used to protect code and data from unauthorized access or modification. This application note discusses usage of the security and flash protection features available on the Kinetis family processors. The chip security and flash protection features controlled using the flash configuration field will be covered in this application note.

In embedded systems, resources are often limited and getting the best possible performance out of those resources can be critical. Although the idea of performance and low power might seem contradictory, the ability to perform a task quickly and then enter a low power mode can lead to an overall reduction in system power consumption. Therefore, almost any system can benefit from efforts to improve performance.

Freescale’s FXTH87xx consist of complex system-on-chip products that contain a pressure sensor, a Radio Frequency (RF) transmitter, a Low Frequency (LF) receiver, an 8-bit S08 microcontroller (MCU), and may contain one or two axis accelerometers, all in one package. As with most S08 solutions, users must program the MCU with their program, but Freescale already ships low-level drivers, as well as compensation routines, within each part. In order to exploit these routines, the developer must be familiar not only with the MCU architecture, but also with the in-flash firmware. The aim of this document is to fast-track the learning curve of the latter part for someone that is already cognizant of the former.
