Embodiment

[0019] In this example, the model of the control chip of the control system is MST718, and the chip model of the FLASH memory is Pm25lv040. MST718 is connected to Pm25lv040 through serial data input terminal (SI), serial data output terminal (SO), serial clock signal terminal (SCK), chip enable control terminal (CE), and write protection status setting terminal (WP). As shown in Figure 1

[0020] Pm25lv040 has a total of 512K×8BIT storage space, divided into 8 blocks (BLOCK), each block is divided into 64 sector groups, each sector group is composed of 16 adjacent sectors (Sector), see the table below :

Abstract

The invention discloses a storing method of controlled system and data and program, which is characterized by the following: comprising controlled chip and externally hung FLASH memory; connecting the controlled chip to the FLASH memory; storing the data and the program of the controlled system in the different sector of the FLASH memory. This invention also discloses a storing method of data and program of the controlled system, which comprises the following steps: a, writing the data and program of the controlled system into the FLASH memory; storing the data and program in different sector; b, activating read / write register of the FLASH memory with the controlled chip; realizing read / writer operation. This invention can simplify system designing, producing and conditioning flow process of the electronic device.

Description

technical field [0001] The invention relates to an electronic equipment control system, in particular to a control system and a method for storing data and programs thereof. Background technique [0002] At present, in order to improve the cost performance of the chip, most of the newly developed single-chip microcomputer chips have greatly compressed the internal program ROM, which leads to the need for external memory to store the data and programs of the electronic equipment control system. Compared with the chip developer, the cost of the chip has been reduced, but the development cost of the electronic equipment has not changed, because the internal ROM for storing the program is canceled for the chip, and the program of the electronic equipment control system is stored in the external FLASH In the memory, because the data of the control system stored in the FLASH memory is easily lost after power failure, the initialization data of the control system is stored in the e...
