EPROM and EEPROM Programmers

It claims that it is "pin compatible with existing ROMs and EPROMs (8K, 16K, 32K and 64K), but that does not include the 2732, and their reference to 32K and 64K was only in regard to ROMs. The TMS2532 is most definitely *not* pin compatible with 2732, and attempting to program a 2532 as a 2732 will likely damage it. They aren't read-compatible either, but damage is far less likely to occur when attempting to read a 2532 as a 2732 (or vice versa). pin TMS2532 2732 --- ------- -------- 18 A11 CE* 20 PD/PGM* OE*/Vpp 21 Vpp A11 As with the earlier TMS2716, which was not compatible with the Intel 2716 or anyone else's, TI tried to second-guess what the standard pinout for the 2732 would be, and failed. At least they anticipated this possibility and referred to their part as the 2532; if it had matched, they could later have dual-marked it 2532 and 2732.
