The TMS2532 was a 32768- bit electrically programmable read- only memory ( EPROM), manufactured by the Texas Instruments Corporation.
Intel simply used the same pinout as it' s 2716 and added an extra addressing pin, thus the 2732. TI again decided to use a different pinout and to differentiate itself from the Intel 2732, it named it the TMS- 2532. So to answer your question, NO, 27 are NOT programmed the same way and are not interchangeable without some board modifications. Virtually ALL eprom burners will do 2732, but some of the cheaper ones will not do 2532.

As for programming voltages, all early Eproms need 25V. Chips ending with an " A" ( like 2732A or TMS- 2532A ) need 21V.
