It should be possible, at least worth to try-there seem to be multiple versions of the willem programmers, so it is a matter of luck. Two Line Output Control Because MA’s are usually used in larger mem- ory dxtasheet, this product features a 2 line control function which accommodates the use of multiple memory connection.

Notify me of follow-up comments by email. All inputs are TTL level except for Vpp. Output Enable G is the output control and should be used to gate data to the output pins, inde- pendent of device selection. Full text of ” IC Datashset The MA should be placed within 2.

Inputs of the paralleled MAs may be con- nected together when they are programmed with the same data.

To most efficiently use these two control lines, it is recommended that Datashedt 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.

I need to program TMSA eprom with Willem 4x programmer…unfortunately,this programmer eatasheet only and A but only read…. A new pattern can be then written to the clerice by following the programming procedure.

The two line control function allows: A high level E input inhibits the other MAs from being pro- grammed. Leave a Reply Cancel reply Your email address will not be published.

EPROM Technical Data

Except for the rating “Operating Temperature Range”, stresses above those iisted in the Tabie “Absolute Maximum Ratings” may cause permanent damage to the device.

Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. Vcc must be applied simultaneously witfi or before Vpp and removed simultaneously or after Vpp. Logic Diagram Table 1. 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.

F capacitor must be placed across GVpp and ground to suppress spu- rious voltage transients which may damage the device. Program Inhibit Programming of multiple MAs in parallel with different data is also easily accomplished. This publication supersedes and replaces all information previously supplied. The recommended erasure procedure for the MA is exposure to shortwave ultraviolet light which has a wavelength of A. It is organized as 4, words by 8 bits. Specifications mentioned in this publication are subject to change without notice.

Chip Enable E is the power control and shojjid be used for device selection. A single 5V power supply is required in the read mode.

Your email address will not be published. Notify me of new posts by email. The data to be programmed is applied, 8 bits in parallel, to the data output pins. Any location can be programmed at anytime – either individually, sequentially, or dataseet random.

Program Verify A verify should be performed on the programmed bits to determine that they were correctly pro- grammed. Data is introduced by selectively programming “O’s” into the desired bit locations.

Search the history of over billion web pages on the Internet. It should be noted that sunlight and certain types of fluorescent lamps have wave- lengths in the A range. The only way to change a “0” to a “1” is by ultraviolet light erasure.
