Description

A kind of novel cd-rom recorder

Technical field

The utility model relates to a kind of novel cd-rom recorder.

Background technology

All electronic chips all will pass through the test macro analysis, and all have the chip (such as OTP, Flash, E2PROM) that needs programming all will just have corresponding function behind the programmable device write-in program, are referred to as test or programming here.It is manually greatly that present test or programming have, and in order to enhance productivity, a common manual operations member can operate several tests or programmable device simultaneously.The operator operates simultaneously several tests or during programming system, can have artificial error, does not press the startup button such as some unit, centre, does not perhaps take away and other maloperation of causing etc.Existing test or programmable device can not realize picking and placeing detection, and a close friend's prompting interface just can't be provided to the operator, also just can not stop this artificial error.

The utility model content

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of low cost, high reliability are provided, and has a novel cd-rom recorder that automatic detection chip picks and places.

The technical scheme that the utility model adopts is: the utility model comprises housing, in described housing, be provided with the main control chip circuit, voltage detecting circuit, empty sheet testing circuit, the burning circuit, external communication interface and storage unit, be provided with the test chip socket at described housing, described voltage detecting circuit, described empty sheet testing circuit, described burning circuit, described storage unit, described external communication interface and described test chip socket all are electrically connected with described main control chip circuit, comprise that also chip picks and places testing circuit, described chip picks and places testing circuit and is electrically connected with described main control chip circuit.

Described chip picks and places testing circuit and forms by being arranged on the testing circuit I that is examined on the chip and the testing circuit II that is arranged on the described main control chip circuit, and described testing circuit I links to each other with described testing circuit II.

Be examined chip and adopt the non-mode that powers on, the mode that relies on its chip pin internal circuit that signal lines is dragged down determines whether chip places.

The beneficial effects of the utility model are: because the utility model comprises housing, in described housing, be provided with the main control chip circuit, voltage detecting circuit, empty sheet testing circuit, the burning circuit, external communication interface and storage unit, be provided with the test chip socket at described housing, described voltage detecting circuit, described empty sheet testing circuit, described burning circuit, described storage unit, described external communication interface and described test chip socket all are electrically connected with described main control chip circuit, comprise that also chip picks and places testing circuit, described chip picks and places testing circuit and is electrically connected with described main control chip circuit, so, the utility model picks and places the setting of testing circuit by described chip, by detecting the level height of IO mouth, determine whether test chip inserts or whether take out, and can detect easily whether test chip is arranged in the socket.

Because whether described cd-rom recorder can intelligent decision have chip to put into socket, so, cd-rom recorder can carry out various operations according to these condition intelligent ground of whether putting into, in addition, after burning finished, cd-rom recorder provided an obvious acousto-optic combination indication to operating personnel, allows the operator know exactly whether test chip inserts or whether take out, make things convenient for staff's operation and management, avoid occurring some maloperations.

Described cd-rom recorder is because what adopt is detection to the chip internal circuit, disobey outer signal enabling, do not power on to target yet, therefore described burning neither can damage being examined chip, can effectively detect chip again puts into, realized easily automatic burning, from another point of view, not only saved client's burning cost but also improved system reliability.

Description of drawings

Fig. 1 is that easy structure of the present utility model connects block diagram;

Fig. 2 is the simple and easy schematic diagram that described chip picks and places testing circuit.

Embodiment

As shown in Figure 1, in the present embodiment, the utility model comprises housing, in described housing, be provided with main control chip circuit, voltage detecting circuit, empty sheet testing circuit, burning circuit, communication interface and storage unit, be provided with the test chip socket at described housing, described voltage detecting circuit, described empty sheet testing circuit, described burning circuit, described storage unit, described external communication interface and described test chip socket all are electrically connected with described main control chip circuit.Comprise that also chip picks and places testing circuit, described chip picks and places testing circuit and is electrically connected with described main control chip circuit.

Described chip picks and places testing circuit and forms by being arranged on the testing circuit I that is examined on the chip and the testing circuit II that is arranged on the described main control chip circuit, and described testing circuit I links to each other when chip is inserted with described testing circuit II.As shown in Figure 2, the testing circuit I is comprised of two ESD diodes and a resistance, and is in parallel with described resistance after described two ESD diodes series connection, an end ground connection wherein, and another termination power, this circuit is present in chip under test inside, need not the outside and redesigns.The detection IO mouth that is connected the main control chip of governor circuit between described two ESD diodes by the chip I/O mouth with described testing circuit II.

The utility model carries out when work according to the following steps: main control chip detects IO and is made as pull-up resistor or externally adds suitable pull-up resistor; Cut off the power supply to chip; Sampling Detection IO discontinuously if the IO level that detects is continuously height, illustrates test chip socket chipless or loose contact continuously; Sampling Detection IO discontinuously is low if the IO level that detects is continuously continuously, illustrates that the test chip socket has chip.

This cd-rom recorder comprises following to the process that chip carries out burning: the IO initialization is carried out in master control; Whether detection chip is put into; Voltage detecting; Empty sheet detects; Burning/recording chip; Checking data; Detection chip is taken out and is processed.

The chip detecting method that the utility model cd-rom recorder has just can be realized at various general IC seats, and peripheral circuit is simple, realizes easily.

The utility model can be applicable to the chip manufacturing field.
