Planning to burn your EPROM programmer – here’s what you need to know!
EPROM
programmer which is also known as Erasable Programmable read-only memory is one
of the most used programmers used among newbie and professionals. Many times,
people with a passion to preserve ancient computer from the 1970s and 80s tend
to replace the failed masked ROM or EPROM.
By the end of
this discussion, some of the important factors that you need to know before
burning your EPROM will be discussed.
First, what are EPROMs?
EPROM stands for
Erasable-Programmable ROM where the ICs hold the code. Often times, the
auxiliary program such as an application, utility, or game can be loaded
immediately on startup. Also, the BASIC interpreter in old computers was
commonly provided by mask ROMs that have embedded code that can’t be changed.
On the other
hand, EPROM is ideal for replacing mask ROMs that have proven to be bad along
with additional applications and utilities and for general tinkering.
1. Voltages can differ: Basically, there are two important
voltages applied to EPROM. One of them is READ voltage that is applied to the
Vcc pin and is usually 5 volts which are used to read the data in the EPROM.
While the other voltage is the programming voltage which is used to burn data
in the EPROM and can vary depending on-chip type and manufacturer.
2. Not all 2716s are equal: It is important to note
that there are fundamental differences between the non-standard programmers and
standard instruments that are made by others. Moreover, you can go through the
explanations online and elaborate on them.
3. Beware of one time programmable EPROM: There are even EPROMprogrammers that are not erasable even though they have the same part number.
Make sure to check it thoroughly so that you get the UV-erasable version.
4.
Choosing a EPROM
programmer: Last, but not the least, choosing the right EPROM programmer is the
first rule to burn and learn how to handle them.
