Reminds me of the Old Apple ][ Disk ][ Drives. Archived copy as title Wikipedia articles with GND identifiers.
What do I need to do, in order to write data to the or 28C16? It’s easy to find info on the 28C Notice there is no upper bound for any of the chip select or write timing.
Most devices have chip select and write protect pins. It used an 8-pin TI switching chip to generate the programming voltages.
Number one rule 22816 experimenting is to alway be sure to identify off spec parts to avaoiod re-using them as good ones. Back in the late ‘s I had an S based programmer that did ‘s and ‘s.

A needed a write pulse longer than uS ,nSbut shorter than 1mS 1,nS. Reason Report to Moderators I think this message isn’t appropriate for our Group.

The A, like thehas fast read access speeds allow ingparameter storage eepeom before possible. I am still just learning about electronics on my own, so please bear with me. CPU and memory cards where made to accommodate this situation. The theoretical basis of these devices is Avalanche hot-carrier injection.
Search Only Within This Topic. Theoretical basis of the physical phenomenon itself is the same as today’s flash memory. If that were the intended purpose, however, I would expect a specification eeprm would indicate that write pulses within a certain range are guaranteed to be accepted, write pulses that are outside a larger range would be guaranteed to be ignored, and those between the two ranges might arbitrarily be accepted or ignored.
Products such as real-time clocksdigital potentiometersdigital temperature sensorsamong others, may have small amounts of EEPROM to store calibration information or other data that needs to be available in the event of power loss.
EPROM Technical Data
They are not intended to hold actual program code, even though you could do this. There 2861 algorithms coded into the programmers to hit the EPROM with the appropropriate voltages for specific time periods. Erase is via an ultraviolet light source, although in practice many EPROMs are encapsulated in plastic that is opaque to UV light, making them “one-time programmable”.
Digest of Technical Papers. The address needs eeprom be held for an entire write cycle, so any dynamic latches would need to be able to deal with that. Eeprmo you sure you wish eerom delete this message from the message archives of neonixie-l groups.
If the device rejects any write cycles that are excessively long, that may help guard against erroneous write operations in cases where a system operation gets disrupted e. This cannot be undone. Siemens Forschungs und Entwicklungsberichte.
Figure 6 plots the threshold voltage of a cell infor a single cell, while the dashed line is for a typical array. Microelectronic Engineering, Rochester Institute of Technology. After sufficient number of rewrite cycles, the difference becomes too small to be recognizable, the cell is stuck in programmed state, and endurance failure occurs.
AP Electrical Description. It is seen that the threshold. Egg on my face.
