A single 5V power supply is required in the read mode. Notify me of new posts by email. Well, as luck would have it, most of the ancient pieces of equipment use EPROMs, and just this kind is not supported by the common programmers, which support the …. Programming of multiple MAs in parallel with the same data can be easily accomplished due to the simplicity of the programming requirements.

EPROM progammers seem like a thing of the past, still, they are very popular for test equipment repair, arcade games, and adtasheet kinds of other occasions where small amounts of data need to be stored in a bulky, fancy package.

I need to program TMSA eprom with Willem 4x programmer…unfortunately,this programmer support only and A but only read….

EPROM Technical Data

If the MA is to be exposed to these types of lighting conditions datassheet extended pe- riods of time, it is suggested that opaque labels be put over the MA window to prevent uninten- tional erasure. Program Verify A verify should be performed on the programmed bits to determine that they were correctly pro- grammed. The program pulse has a maximum width of 55ms. The MA should be placed within 2.

Although only “O’s” will be pro- grammed, both “1 ‘s” and “O’s” can be presented in the data word. A high level E input inhibits the other MAs from being pro- grammed. Any location can be programmed at anytime – either individually, sequentially, or at random. Your email address will not be published. When the address and data erom stable, a 50ms, active low, TTL program pulse is applied to the Epprom input.

Search the history of over billion web pages on the Internet. The MA with its single 5V power supply and with an access time of ns, is ideal suited for applications where fast turn around and pattern experimentation one important requirements. This publication supersedes and replaces all information previously supplied.

Specifications mentioned in this publication are subject to change without notice. Vcc must be applied simultaneously witti or before Vpp and removed simultaneously or after Vpp.

All inputs are TTL level except for Vpp. Chip Enable E is the power control and shojjid be used for device selection. Notify me of follow-up comments by email. It should be noted that sunlight and certain types of fluorescent lamps have wave- lengths in the A range. SimonsDialogs — A wild collection of random thoughts, observations and learnings.

To most efficiently use these two control lines, it is recommended that E be decoded and used as the primary device selecting function, while G should be made a common connecti on to all devices in the array and connected to the READ line from the system control bus.

Vcc must be applied simultaneously with or before Vpp and removed simultaneously or after Vpp. Learn how your comment data is processed.

Logic Diagram Table 1. The only way to change a “0” to a “1” is by ultraviolet light erasure. Program Inhibit Programming of multiple MAs in parallel with different data is also easily accomplished. The data to be programmed is applied, 8 bits in parallel, to the data output pins. Inputs of the epron MAs may be con- nected together when they are programmed with eatasheet same data.

This ensures that all deselected memory devices are in their low power standby mode and that the output pins are only active when data is required from a particular memory device. This site uses Akismet to reduce spam.

Research shows that constant exposure to room level fluorescent lighting could erase a typical MA in approxi- mately 3 years, while it would take approximately 1 week to cause erasure when exposed to the direct sunlight. These are stress ratings oniy and operation of the device at these or any other conditions above those indicated in the Operating sections of this specification is not implied.
