Abstract
The utility model is applicable to the chip technical field, which provides a flash memory chip. In the utility model, the flash memory chip is provided with 52 pins and has extra 4 pins than the traditional flash memory chip. The 52 pin include user-defined function pins which can be flexibly connected with fixing function pins according to the need of the user to define function or are not used. Therefore, compared with the traditional flash memory chip, the utility model has higher adaptability and can meet the various requirements of the user.
Description
Technical field
The utility model belongs to the chip technology field, relates in particular to a kind of flash chip.
Background technology
Flash memory belongs to new-type storer, is used for replacing traditional magnetic disk to carry transmission information, and it has, and volume is little, capacity is big, fireballing characteristics, does not need electric power to keep the information of preservation.It is mainly used in various digital equipments, as digital camera, MP3 player, USB flash disk, mobile phone, handheld device (as PSP) etc.
The outline packages that existing flash chip adopts is fixed, and as shown in Figure 1, packing forms is TSOP48, i.e. 48 pins, physical dimension is 12 * 20 * 1.2mm, still, along with the development of technology, the packing forms of this flash chip can not satisfy many-sided demand of user.
The utility model content
The purpose of this utility model is to provide a kind of flash chip, and it is single to be intended to solve existing flash chip packing forms, can not satisfy the problem of many-sided demand of user.
The utility model is to realize like this; a kind of flash chip; described flash chip comprises 52 pins; described 52 pins comprise the fixed function pin; described fixed function pin comprises: at least one command latch enable end pin; at least one address latch Enable Pin pin; at least one reads the Enable Pin pin; at least one writes the Enable Pin pin; at least one write-protect end pin; at least one power end pin; at least one ground end pin; at least eight data I/O end pins; at least one chip enable end pin and at least one preparation/busy output terminal pin; also comprise at least one custom feature pin in described 52 pins; arbitrary pin in the described custom feature pin optionally is connected with arbitrary pin in the described fixed function pin, or the arbitrary pin in the custom feature pin is unsettled.
In the said structure, the package dimension of described flash chip is 14 * 22 * 1.4mm.
In the utility model, flash chip is provided with 52 pins, have more 4 pins with respect to existing flash chip, comprise the custom feature pin in these 52 pins, the custom feature pin can be connected with the fixed function pin neatly according to user's needs, to define its function, perhaps the custom feature pin is unsettled, therefore the flash chip that provides of the utility model is compared with existing flash chip, and adaptability is greatly improved, and can satisfy the many-sided demand of user.

Fig. 2 is the external structure synoptic diagram of the flash chip that provides of the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 2 shows the external structure of the flash chip that the utility model embodiment provides.
The package dimension of the flash chip that the utility model provides is 14 * 22 * 1.4mm; flash chip comprises 52 pins; 52 pins comprise the fixed function pin; the fixed function pin comprises: at least one command latch enable end pin; at least one address latch Enable Pin pin; at least one reads the Enable Pin pin; at least one writes the Enable Pin pin; at least one write-protect end pin; at least one power end pin; at least one ground end pin; at least eight data I/O end pins; at least one chip enable end pin and at least one preparation/busy output terminal pin; also comprise at least one custom feature pin in 52 pins; arbitrary pin in the custom feature pin optionally is connected with arbitrary pin in the fixed function pin, or the arbitrary pin in the custom feature pin is unsettled.The order that pin is arranged among the utility model embodiment does not limit, can be according to user's needs and the technology arrangement conveniently and arbitrarily of making flash chip.
In the utility model embodiment, flash chip is provided with 52 pins, have more 4 pins with respect to existing flash chip, comprise the custom feature pin in these 52 pins, the custom feature pin can be connected with the fixed function pin neatly according to user's needs, to define its function, perhaps the custom feature pin is unsettled, therefore the flash chip that provides of the utility model is compared with existing flash chip, and adaptability is greatly improved, and can satisfy the many-sided demand of user.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
