Problems solved by technology

[0004] In the existing technology, in the first solution, if the chip to be programmed is short-circuited, it will cause damage to the programmer
[0005] The disadvantage of the second solution is that on the one hand, some chips, especially those that have been programmed, should not be powered on for too long, otherwise they will enter the normal working state, so that they can be programmed
On the other hand, prolonging the time in this way will greatly affect the efficiency

Embodiment Construction

[0057] In order to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.

[0058] In view of the above-mentioned MCU chip programming process, in some cases, it is necessary to program on the PCB board that has been soldered with components, and the components on the PCB, especially the capacitor at the power supply end, will greatly affect the power-on and power-off. electricity time. The present invention adopts a system and method for realizing the self-adaptive control of chip power-on time in the programmer, and uses software to realize the on and off of the hardware power supply, and to discharge the power supply and the ground when the power is off, and through continuous Adjust the power-on time required before entering the programming sequence when programming the MCU chip, automatically obtain the power-on time and power-off time required for programming the chip, and im...

Abstract

The invention relates to a system and a method of realizing self-adaptive control of a power-up time of a chip in a programmer. The system includes a chip connection element, an operation element, a control element and a power-up control circuit. The power-up control circuit is connected with the chip, which is to be burned, through the chip connection element. The control element is connected with the chip connection element, the operation element and the power-up control circuit at the same time. According to the system and the method of adopting the structure and realizing self-adaptive control of the power-up time of the chip in the programmer, the controllability for the power-up time can be realized, the one power-up time which can enable the chip to be normally burned is obtained in a time adjustment process, a discharging circuit is used to then carry out quick discharging in a power-off process, thus a short-circuit protection function of the programmer is not impacted, and a discharging time is greatly reduced. The system and the method can be used to burn chips with various power-up time requirements in a case of protecting the programmer without carrying out different time modification for different PCBs or removing capacitors on the PCBs, and have a more extensive application range.

Description

technical field [0001] The invention relates to the field of control design, in particular to the design of self-adaptive control of chip power-on time in a programmer, and specifically refers to a system and method for realizing self-adaptive control of chip power-on time in a programmer. Background technique [0002] When using MCU products, the chips will be programmed in batches using the programmer provided by the MCU chip design company. When the MCU chip is programmed, the programmer will first power on the MCU chip, and then enter the corresponding programming sequence to complete the programming of the MCU chip. If the MCU chip has been soldered on the PCB board, the power supply terminal of the PCB will generally have a capacitor connected to it. This capacitor and the resistor on the programmer form an RC circuit. There will be a charging process that cannot be omitted, and the power-on time will be reduced. Delay, when the power supply voltage does not reach the...
