In this post, MiniTool will introduce EPROMs definition, details, and program.
There are different types ofROMin the market, such asEEPROMandflash memory.
Definition of EPROM
What is EPROM?
The EPROM, sometimes called EROM, is an abbreviation for erasable programmable read-only memory.
Thus, OTP versions of EPROMs and EPROM-based microcontrollers are manufactured.
When the wavelength is less than 400 nm, the EPROM starts to be erased.
Exposure time for Indoor fluorescent lighting of three years or sunlight of a week may cause erasure.
The EPROM has a limited but large number of erase cycles.
The surrounding silica dioxide accumulates damage in each cycle, making the chip unreliable after several cycles.
Compared with other forms of memory, EPROM programming speed is slower.
Even the dust in the package can prevent certain batteries from being erased.
At first, people thought that EPROM was too expensive for mass production and was limited to development.
Before these EEPROM and flash memory eras, some microcontrollers used an on-chip EPROM to store their programs.
Like EPROM chips, such microcontrollers had a windowed (expensive) version for debugging and program development.
The same chip was produced in an opaque OTP package (which is cheaper).
