The two line control function allows: EPROM progammers seem like a thing of the past, still, they are very popular for test equipment repair, arcade games, and all kinds of other occasions where dayasheet amounts of data need to be stored in a bulky, fancy package.
A program pulse must be applied at each address location to be programmed. 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.
The program pulse has a maximum width of 55ms. Epro, me of new posts by email. This site uses Akismet to reduce spam. Vcc must be applied simultaneously witfi or before Vpp and removed simultaneously or after Vpp. Chip Enable E is the power control and shojjid be used for device selection.
IC Datasheet: 2732 EPROM
This publication supersedes and replaces all information previously supplied. Vcc must be applied simultaneously with or before Vpp and removed simultaneously or after Vpp. Specifications mentioned in this publication are subject to change without notice. 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.
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exposure to shortwave ultraviolet light which has a wavelength of A. Leave a Reply Cancel reply Your email address will not be published. If the MA is to be exposed to these types of lighting conditions for extended pe- riods of time, it is suggested that opaque labels be put over the MA window to prevent uninten- tional erasure.
Although only “O’s” will be pro- grammed, both “1 ‘s” and “O’s” can be presented in the data word.
I need to program TMSA eprom with Willem 4x programmer…unfortunately,this programmer support only and A but only read…. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability.
Vcc must dagasheet applied simultaneously witti or before Vpp and removed simultaneously or after Vpp. The transparent lid allows the dagasheet to expose the chip to ultraviolet light to erase the bit pattern. The data to be programmed is applied, 8 bits in parallel, to the data output pins. The only way to change a “0” to a “1” is by ultraviolet light erasure. It is organized as 4, words by 8 bits.

Program Inhibit Programming of multiple MAs in parallel with different data is also easily accomplished. Program Verify A verify should be performed on the programmed bits to determine that they were correctly pro- grammed. Logic Diagram Table 1. Two Line Output Control Because Eporm are usually used in larger mem- ory arrays, datashee product features a 2 line control function which accommodates the use of multiple memory connection.

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. To most efficiently use these two control lines, it is recommended that E be decoded and used as the datassheet 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.
Except for the rating “Operating Temperature Range”, stresses above those iisted in the Tabie “Absolute Maximum Ratings” may cause permanent damage to the device.
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. 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.
