Abstract

A program burner comprises a memory device, an MCU (microprogrammed control unit) and a voltage comparator, wherein the memory device is electrically connected with MCU which automatically copies updated burn object codes in the memory device into the MCU internal memory for storage; the burn object codes stored in the MCU internal memory are burned into an IC (integrated circuit) chip of object codes to be burned through a communication protocol; after the burning is finished, programs are run, and the voltage comparator is used for comparing a voltage value generated by an interior circuit of the IC chip of the object codes to be burned with an assigned voltage value of the voltage comparator: if the voltage of the IC chip of the object codes to be burned is equal to the assigned voltage value, the burning succeeds, and the chip is complete and can be normally operated; otherwise, reburning is required. The program burner has the advantages of convenience in burn object code updating and capabilities of improving production efficiency and reducing production cost, and can automatically determine whether the chip is normal or not after the burn object codes are burned into the IC chip of the object codes to be burned and the like.

Description

Programmer

Technical field

The utility model relates to a kind of programmer.

Background technology

Progress along with science and technology, IC chip with speed faster, larger capacity, more pin, lower operating voltage is produced, for the quick and huge change of semiconductor industry, people are except absorbing at any time new message, develop better product, produce outside more more valuable commodity the better programmer of the performance that also will select.

So-called programmer is actually one the instrument of programmable integrated circuit data writing, and programmer is mainly used in the programming (or claiming to write with a brush dipped in Chinese ink) of the chip of single-chip microcomputer (containing embedded), storer (containing BIOS) and so on.The pattern of programmer is varied, and programmer can divide universal type cd-rom recorder, yield production type cd-rom recorder, tailored version cd-rom recorder on function.Programmer is by the demand of using, can be divided into research and development with and volume production with two large types.

Existing various programmer after the IC chip, can not judge whether chip can work with burning program, need to detect the IC chip that burning is good with different devices, has reduced production efficiency, has increased production cost.

The utility model content

The purpose of this utility model is for the problems referred to above, and providing a kind of to society can be burnt to the burning object code after burning object code IC chip by automatic decision, the programmer whether the IC chip works.

the technical solution of the utility model is: design a kind of programmer, comprise: the memory storage that stores the burning object code, MCU and voltage comparator, described memory storage is electrically connected by communication interface and described MCU, when the described burning object code that described MCU stores in described memory storage being detected has renewal, automatically described burning object code is copied into depositing to described MCU internal memory, the described burning object code that leaves described MCU internal memory in is burnt to by communications protocol to be treated in burning object code IC chip, described voltage comparator treats that to described the magnitude of voltage that produces in burning object code IC chip and the assigned voltage value in described voltage comparator compare, described assigned voltage value is the described magnitude of voltage that program operation internal circuit produces after the described burning object code of burning object code IC chip success burning, describedly treat that the voltage in burning object code IC chip equates with described assigned voltage value, burning success, chip is normal, describedly treat that voltage and described assigned voltage value in burning object code IC chip are unequal, need burning again, still unequal repeatedly, chip is abnormal.

As to improvement of the present utility model, also comprise hummer, described hummer and described voltage comparator are electrically connected.

As to improvement of the present utility model, described hummer replaces with pilot lamp, and described pilot lamp and described voltage comparator are electrically connected.

As to improvement of the present utility model, described memory storage is portable hard drive, USB flash disk, storage card, CD or floppy disk.

As to improvement of the present utility model, described communication interface is USB interface, JTAC interface or com interface.

As to improvement of the present utility model, described communications protocol is I2C, ISP or serial port communicating protocol.

As to improvement of the present utility model, described voltage comparator is the no-voltage comparer, have the zero-crossing comparator of hysteretic characteristic, hysteresis voltage comparator or window voltage comparator.

As to improvement of the present utility model, the LED light source of described pilot lamp is red, yellow, blue, green or white.

The utlity model has the burning object code upgrades conveniently, has improved production efficiency, has reduced production cost, can the burning object code be burnt to after burning object code IC chip automatic decision the advantage whether the IC chip works.

Description of drawings
