Embodiment Construction

[0023] The present invention will be further described below in conjunction with embodiments and accompanying drawings.

[0024] Please see figure 1 A programmer 9 of the present invention includes a main control chip 1, a FLASH data storage module 2, an operating state display module 6, a function selection switch 4, a communication interface module 3 with an upper computer 8, and a gap between the programmer and the chip 7 to be programmed. The programming interface module 5.

[0025] In the programmer 9 of the present invention, the main control chip 1 is connected with the FLASH data storage module 2 by using a port to expand the RAM memory, and can directly perform read and write access to the FLASH. The data stored in the FLASH data storage module 2 includes three parts: ① user programming data; ② user configuration parameter data; ③ readback data of the chip to be operated. Among them, the user configuration parameter data includes the storage start address, end addre...

Abstract

The invention discloses a programmer and a programming method thereof. The programmer comprises a main control chip, a FLASH data storage module, an operating state display module, a functional selection switch, a communication interface module of an upper computer and a programming interface module between the programmer and a chip to be programmed, wherein the main control chip is connected with the FLASH data storage module, the operating state display module and the functional selection switch respectively; the communication interface module is connected with the upper computer and the main control chip; and the programming interface module is connected with the main control chip and the chip to be programmed. The programmer can support an on-line operation mode and an off-line operation mode.

Description

technical field [0001] The invention belongs to the technical field of memory programming, and in particular relates to a memory programmer and a programming method thereof. Background technique [0002] In the field of consumer electronics, the products developed based on MCU have accounted for the vast majority. They are widely used in various occasions, such as calculators, remote controls, voice coding, home appliance control and various toy circuits. The product life cycle is long and the market Broad prospects. The MCU chips and EEPROM products independently developed by Sike are mainly used in the development of handheld consumer electronics products. The main problem at present is that there is no programming tool for OTP ROM and EEPROM inside the chip to complete the development of the system solution. At present, there is no ready-made programmer tool in the market or in the company for programming the OTP chip and EEPROM independently developed by China Resource...
