Low-temperature self-adaptive chip and low-temperature self-adaptive method for chip

Abstract

The invention discloses a low-temperature self-adaptive chip and a low-temperature self-adaptive method for the chip. The low-temperature adaptive chip comprises: a temperature sensor used for acquiring the internal temperature of the chip in real time; a reset module which is connected with the temperature sensor and used for sending a corresponding reset level signal to a chip logic circuit according to the size relation between the internal temperature and a pre-stored chip low-temperature threshold value; a chip logic circuit which is connected with the reset module and is used for starting execution of logical operation or stopping execution of logical operation according to the reset level signal; and a clock module which is connected with the chip logic circuit and is used for sending a clock signal to the chip logic circuit and generating heat in the process of generating the clock signal through a crystal oscillator of the clock module. Therefore, the corresponding reset level signal is sent to the chip logic circuit according to the internal temperature of the chip, and the chip is preheated by using the clock module, so that the low-temperature self-adaption of the chip can be realized, and the performance of the chip is improved.

Description

technical field [0001] The invention relates to the field of chip technology, in particular to a low-temperature self-adaptive chip and a low-temperature self-adaptive method for the chip. Background technique [0002] The working temperature level of the chip refers to the natural environment temperature, that is, the climate temperature faced by the whole machine or the module for many years. Since the adaptability of the chip to the natural environment and the temperature of the working environment are different, the working temperature level of the chip limits the temperature of the chip. application range. Different grades of chips have different requirements for operating temperature. For example, commercial grade chips can work at 0°C-70°C, industrial grade chips can work at -40°C-85°C, and automotive-grade chips can work at -40°C-125°C. Military-grade chips can work in the temperature range of -55°C-125°C. If they work outside the operating temperature range, the ac...

[0002] The working temperature level of the chip refers to the natural environment temperature, that is, the climate temperature faced by the whole machine or the module for many years. Since the adaptability of the chip to the natural environment and the temperature of the working environment are different, the working temperature level of the chip limits the temperature of the chip. Application range

Different grades of chips have different requirements for operating temperature. For example, commercial grade chips can work at 0°C-70°C, industrial grade chips can work at -40°C-85°C, and automotive-grade chips can work at -40°C-125°C. Military-grade chips can work in the temperature range of -55°C-125°C. If they work outside the working temperature range, the accuracy of the chip will become very poor, or even fail to start, which will reduce the performance of the chip

In the prior art, for a chip in an abnormal state in a low-temperature environment, it needs to be powered off and restarted, and it is necessary to judge whether it can be restarted according to the external environment temperature, which reduces the user experience.
