How to program car computer more horsepower eeprom

Since the quartz glass window required for erasing the chip with UV-C light is a big part of the production costs for the chip, this chip is available with and without this window. Without the window, the chip cannot be erased using UV-C light.

After programming an erasable eprom with UV-C light, the glass window should be closed with a sticker so no sunlight can enter. Sunlight also contains components of UV-C light and can eventually erase data from the eprom. Since individual bytes can be erased without erasing everything, these individual bytes can be overwritten, in effect.

In this process, 64, or bytes at once are loaded into the memory chip and programmed simultaneously as a block. This clearly shortens programming times. These chips can be erased electrically - completely or by the block - and some - like the AT28C Reasons include, for instance, that the Flash eproms, even the ones with a small amount of memory space, are only available in housings with 32 or more pins.

A 28F with 32 pins is therefore not pin compatible to a 27C with 28 pins and the same memory capacity. This means that only one bit at a time can be accessed, and the accessed address must be communicated bit by bit as well, but it has the major advantage that the serial EEPROM comes with a small 8-pin housing.

These chips are therefore popular when space or accessing cables are to be saved and no large amounts of data or high speeds are required. These memory devices can be written to very quickly in this case, it is generally referred to as writing, not burning and each byte can be overwritten just as quickly and easily, i.

The disadvantage of this technology is that the chips lose their memory space when the power supply is cut off. These chips have the major advantages of the RAM chips very high speed and easy overwriting of existing data and retain their data when power is cut off. This can be achieved in two ways: The first group removes the disadvantage of the original RAMS with a built-in battery that protects the memory space from losing its data when the power is cut off.

According to the manufacturer, the battery lasts for ten years according to type. The advantages of fast RAM access and easy overwriting remain. These chips are put into many devices as "mini-PC's" and guide, for instance, printers, heaters, microwaves, alarm clocks etc.. With these chips, erasure takes place by exposure to intensive ultraviolet light in the area of nm wavelength.

Since UV-C light is very dangerous to the eyes and also carcinogenous, these chips are erased in special eprom erasure devices.

These only allow the light to be turned on after the housing is closed. When the housing is opened, the light is immediately switched off. JavaScript seems to be disabled in your browser. You must have JavaScript enabled in your browser to utilize the functionality of this website.
