For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: comprise main control chip, communication interface, cable, target FLASH chip; It is characterized in that: also comprise the SD card; The SD card is electrically connected with main control chip, communication interface successively, and communication interface is connected with target FLASH chip through cable.Effect is: data storage does not need computer and upper computer software in the SD card, realizes the portable data programming.
Further, said main control chip is based on the high-speed chip of Cortex-M3 kernel.Wherein, main control chip comprises the SD card controller, and the SD card is electrically connected with the SD card controller of main control chip.Said main control chip satisfies small size, low-power consumption, the simple requirement of technical scheme.Simultaneously can also satisfy the mass data processing capacity.
Further, said portable serial FLASH programming device based on the SD card also comprises man-machine friendship equipment, and the human-computer interaction device comprises switch, pilot lamp, hummer, and the human-computer interaction device is electrically connected with main control chip.
Further, said switch is electrically connected with main control chip.
Further, said pilot lamp is electrically connected with main control chip, shows performed duty.
Further, said hummer is electrically connected with main control chip.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, have the following advantages:
(1) accelerates burn writing speed, improved production efficiency; The burn writing speed of the utility model is accelerated to 16% of former burn writing speed at least, and the time that is equivalent to programming 2MB data is no more than 20 seconds;
(2) not in the control of needs through computing machine, programming chip has one by one been simplified the programming operation when having simplified device structure again;
(3) only carrying the SD card through plate can Update Information through computer at any time;
(4) dwindled the volume of equipment, be easy to carry;
(5) more convenient to operate, only need to push the button and just can accomplish programming;
