What Is IC Programming?

The manufacturer bought the above-mentioned various recordable ICs from the semiconductor manufacturer. The data area is blank. Before the assembly, the latest version of the control program and data are written with the IC writer. This is a more important than IC test. The process is generally performed by the final electronic product manufacturer, and it is also an area rarely discussed.

IC burning

The burning was approved. The English name of the writer is PROGRAMMER. Some people call it WRITER. Earlier some people called it BURNER. This kind of machine is used to program [PROGRAM]. CELL [cell] data, resulting in different functions, most of the previous ICs were fixed-function ICs [DEDICATED ID], so designers designing a circuit board must use a variety of fixed-function ICs, Manufacturers need to prepare many types of ICs. Since the emergence of programmable ICs, designers only need to prepare one type of IC and then burn it into ICs with different functions. The preparer only needs to purchase one type of IC. The preparation is convenient. But you need to prepare a writer to burn it

When referring to the writer, most people think that the CD-RW is only understood by the electronics engineer. The IC writer used in factories and R & D units is another electronic product that has developed earlier and is more professional.

Early recordable ICs were mainly EPROMs that could remove data from ultraviolet rays, and the amount was not large. In recent years, various programmable ICs such as EEPROM, Flash, Nand Flash, Nor Flash, PLD, CPLD, and other highly integrated ICs have come out one after another. Various information, communication, home appliances, and handheld electronic products have been Significant improvements have been made in power saving and reliability, thanks in part to advances in programmable ICs.

The integration and popularization of recordable ICs is getting higher and higher, and the production capacity requirements of IC writers are becoming higher and higher. In addition, China has become the world's electronic product manufacturing factory, and it is bound to be the most demanded area for the writer. Among them, the MCU and Flash (more than 128M) two types of major IC programming are the strategic focus of writer development.

MCU class programmable IC

MCUs can be programmed with ICs. At present, there are many single-chip controllers (SINGLE MCUs) on the market that can be used to write data once or multiple times through the supporting writer. MCUs that can only be programmed once are called OTPMCUs (English: ONE TIME PROGRAMBLE MCU), while the MTP MCUs (English: MULTI TIME PROGRAMBLE MCU) are MCUs that can be programmed multiple times.

OTP MCUs are usually burned in by the manufacturer through a matching writer before product assembly. Once such ICs are burned, the burned data cannot be changed again.

MTP MCUs are different from OTP MCUs. This type of IC can be programmed and erased multiple times through the supporting writer. Some built-in FLASH MCUs can even be programmed no less than 100,000 times.

Memory Class Burnable IC

Memory ICs can be programmed: There are many types, such as EPROM, EEPROM, NOR FLASH, SPROM, NAND FLASH, etc.

EPROM, NOR FLASH, EEPROM, and SPROM are mainly used to store our data or programs. We have become commonplace. Compared with NAND FLASH manufacturers, it can be said that manufacturers are almost everywhere, and there are quite a few universal burners on the market. The writer can program data into these ICs.

NAND FLASH is only produced by several manufacturers such as Samsung and is currently widely used in U disk, MP3, MP4, ELA and electronic dictionaries.

IC programming universal writer

For most EPROM, EEPROM, NOR FLASH, SPROM, the universal writer can meet the requirements of data programming, and some high-end writers even support some well-known brands of OTP or MTP chips, such as Heluo's Some writers can program OTP and MTP of MICROCHIP, EMC and other manufacturers.

IC programming writer

Each OTP and MTP manufacturer has its own writer for the corresponding chip. In addition, some manufacturers and individuals make special writers for individual or part of EPROM, EEPROM, NOR FLASH, to meet production or other needs.

IC programming online programming

Some systems need to be modified or upgraded automatically or manually during operation, which requires online programming. For example, digital electronic dictionaries currently on the market, manufacturers usually provide automatic network upgrade services. When consumers need to update their learning content or upgrade the system after a period of use, they can manually upgrade the product through a computer.
