PLEASE HELP ME FIND INFO ON A CHIP I'D LIKE TO USE

UFO Joe 20 years ago

Can anyone please help me to find a datasheet, or at least pinouts for the Texas Instrument TSP5220CNL voice synthesis chip.

Or where I might find them. I have checked Datasheets.or.uk, Datasheetarchive.com, Alldatasheet.com, Chipdocs.com, Datasheets4u.com, Datasheetcatalog.com and Chipcatalog.com without any success. I also tried the Texas Instrument website.

It was used in vintage arcade machines, the TI/44a computers, the Speak 'n Spell, etc.

Also does anyone know of any EXTERNAL voice synthesizer boxes that ran on PCs using the serial port that used the TSP5220 chip?

Any help would be greatly appreciated.

Thanks in advance!

Google is your friend. Search for TSP5220 yields this as top result:

Lots of pictures of a device that uses RS-232 to communicate with a PC or anything else. Chips are socketed and the board looks simple enough to maybe reverse engineer, with the right equipment (logic analyzer).

Thank you very much for the quick reply.

Are you sure the TSP5220CNL is the same as the TMS5220? What are the differences?

Thank you >

I don't know. Perhaps not. The web page

formatting link

claims to list all known old Texas Instruments Speech ICs. The TSP5220 isn't mentioned there at all, so I thought it was a typo.

Sorry for the confusion.
