Dingshenghe——What chip can the air pump use?

Air pumps are widely used. Products such as tires, basketballs, and SUP paddle boards all need air pumps to help inflate them to reach the gas standard for normal use. Personalized functions such as gas detection, automatic filling and stopping, and filling and discharging protection of the air pump replace the inaccuracy of manual monitoring, so that the inflation can be accurately measured and monitored, achieving fine numerical differences, and prolonging the service life of objects such as tires.
The composition of an air pump solution includes a variety of components, among which the chip occupies an important core position. So, what chip is used in the air pump solution?
First of all, the chip of the air pump solution must have ADC and MCU. ADC refers to an analog-to-digital converter, a converter chip that can help us convert analog signals into digital signals. For example, when the air pump inflates the tire, the air pressure sensor can monitor the value of the gas in the tire, but the data obtained at this time is an analog signal, and we cannot directly read the analog signal directly, just like blowing the tire head-on When there is a gust of wind, you can only feel the strength of the wind but cannot tell the wind level. What the air pressure sensor reads is such an analog signal. It needs an ADC chip to convert the analog signal into a digital visual display. It allows people to directly see the range of the gas value inside, and then judge whether we need to continue to inflate the tire.
The ADC chip CS1237 is a chip used in the air pump solution. It is a high-precision, low-power analog-to-digital conversion chip with a differential input channel, a built-in temperature sensor and a high-precision oscillator. MCU can communicate with CS1237 through 2-wire SPI interface SCLK, DRDY, and configure it, such as channel selection, PGA selection, output rate selection, etc.
The MCU chip is the core component of the air pump solution design, and its performance memory size and functions directly affect the function realization of the air pump solution. The MCU chip is as important as a computer CPU, without which the function of the air pump solution cannot be used normally. But before it is selected as an air pump solution, it is just a blank chip with a wafer package and pins. Its importance is that it can load software and drive other components to perform their functions after the software is injected. Just like our human brain, the brain controls the operation of the body's various limbs and internal organs. Therefore, in the selection of the MCU chip, it is necessary to select a memory and a programming memory that can meet the functions of the air pump solution.
The air pump solution MCU chip CSU8RP1185 is a high-performance single-chip microcomputer with 8-bit RISC architecture, which integrates 24Bit high-precision ADC and LCD display module. Peripheral devices of commonly used measurement systems only need 7 common capacitors. The chip realizes that the system calibration data can be saved in the OTP within the range of the working voltage (2.5~3.6V).
Of course, the chip of the air pump solution is not limited to one or two, and needs to be selected according to the specific situation. The main function of the chip is to complete calculations and process tasks. It has a very wide range of functions, not limited to the air pump solution, it exists in our daily life, and it is a very important existence in our smart life.
