Description
Technical field
The utility model relates to the burning device of four EEPROM of a kind of burning simultaneously.
Background technology
EEPROM (Electrically Erasable Programmable Read-Only Memory), EEPROM (Electrically Erasable Programmable Read Only Memo) is the storage chip that data are not lost after a kind of power down.EEPROM can on computers or wipe existing information, reprogramming on the specialized equipment.Produce the professional cd-rom recorder-Taiwan of many uses in electronics industry and grind instrument, Lip river, river, Taiwan; Need mount wiring board, after powering on, complete machine be carried out the ISP burning.Professional cd-rom recorder price height, input cost is big, and online ISP burning efficient is low, influenced greatly by periphery circuit.
Summary of the invention
In view of above-mentioned defective, the purpose of this utility model provides the burning device of four EEPROM of a kind of burning simultaneously, and its circuit structure is simple, and is with low cost.
The utility model is realized by the following technical solutions: the burning device of four EEPROM of a kind of burning simultaneously, comprise the PC, writing card and the power supply that are provided with burning program, it is characterized in that: the LPT output terminal of described PC connects by the input end of writing card, described writing card is provided with four groups of 74LS05 phase inverters, described four groups of 74LS05 phase inverters are connected with the EEPROM that treats burning respectively, and described power supply is the each several part power supply of device.
The utility model sees through computer parallel port and comes Simulation with I IC communication, drives by 74LS05, simultaneously four EEPROM is read and write, and has characteristics such as high-level efficiency, low cost, stay in grade.And the state of every burning IC of the visual interface reflection of the utility model employing computing machine, and can very count umber of defectives to burning and add up, so that the operator judges the burning result intuitively.
Description of drawings
Fig. 1 is a structural representation block diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, the utility model provides the burning device of four EEPROM of a kind of burning simultaneously, comprise the PC, writing card and the power supply that are provided with burning program, it is characterized in that: the LPT output terminal of described PC connects by the input end of writing card, described writing card is provided with four groups of 74LS05 phase inverters, described four groups of 74LS05 phase inverters are connected with the EEPROM that treats burning respectively, and described power supply is the each several part power supply of device.
Described EEPROM model comprises 24C01,24C02,24C04,24C16,24C32 and 24C64.
The utility model sees through the parallel port Simulation with I IC communication of computing machine with the core of computing machine as native system, drives by 74LS05 monomer I C is carried out burning, and the situation of burning is reflected on the computer monitor strictly according to the facts accurately.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
