IC Datasheet: 2732 EPROM

Programming of multiple MAs in parallel with the same data can be easily accomplished due to the simplicity of the programming requirements. F capacitor must be placed across GVpp and ground to suppress spu- rious voltage transients which may damage the device.

Except for the rating “Operating Temperature Range”, stresses eprmo those iisted in the Tabie “Absolute Maximum Ratings” may cause permanent damage to the device. A single 5V power supply is required in the read datasbeet. If the MA is to be exposed to these types of lighting conditions for extended pe- riods of time, it is suggested that opaque dstasheet be put over the MA window to prevent uninten- tional erasure. I need to program TMSA eprom with Willem 4x programmer…unfortunately,this programmer support only and A but only read….

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. All inputs are TTL level except for Vpp. The levels required for the address and data inputs are TTL.


The program pulse has a maximum width of 55ms. The integrated epom i. Some lamps have a filter on their tubes which should be removed before erasure.

Notify me of follow-up comments by email. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability.

Vcc must be applied simultaneously witti or before Vpp and removed simultaneously or after Vpp. Specifications mentioned in this publication are subject to change without notice. Program Inhibit Programming of multiple MAs in parallel with different data is also easily accomplished. Well, as luck would have it, most of the ancient pieces of equipment use EPROMs, and just this datasbeet is not supported by the common programmers, which support the ….

Vcc must be applied simultaneously witfi or before Vpp and removed simultaneously or after Vpp. The MA should be placed within 2. Learn how your comment data is processed.

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 dataaheet direct sunlight.

This publication supersedes and replaces all information previously supplied.

TMS 2532 EPROM adapter: one byte every 50 ms…..

The recommended erasure procedure for the MA is exposure to shortwave ultraviolet light which has a wavelength of A. SimonsDialogs — A wild collection of random thoughts, observations and learnings. The MA with its single 5V power supply and with an access time of ns, is ratasheet suited for applications where fast turn around and pattern experimentation one important requirements.


Your email address will not be published. The two line control function allows: The dafasheet lid allows the user to expose the chip to ultraviolet light to erase the bit pattern. Vcc must be applied simultaneously with or before Vpp and removed simultaneously or after Vpp.

This ensures that all deselected memory devices are in their low datashfet standby mode and that the output pins are only active when data is required from a particular memory device. Search the history of over billion web pages on the Internet. Chip Enable E is the power control and shojjid be used for device selection. However, SGS-THOMSON Microelectronics assumes no responsibility for tine consequences of use of such information nor for any infringement of patents or other rights of third parties which may result from its use.

Two Line Output Control Because MA’s are usually used in larger mem- ory arrays, this product features a 2 line control function which accommodates the use of multiple memory connection.
