Just looking at the HCR software disassembly, the 2532/2564/2716/2732 parts (all 24 pin devices) share common programming code which uses a single 50ms pulse. That's much longer than allowed by the WS57C43C and may well cause damage. So I don't think it will be possible to program these with the original HCR software.From the data sheet (attached) they require "VCC = 6.25 V ± 0.25 V, VPP = 12.75 ± 0.25 V" and "tPW Program Pulse Width 100 to 200 μs" to program them. I wonder if the 2732 settings (having manually selected the 12.5V programming voltage) are just not right. I also include the data sheet for the NMOS 2732 for comparison.
I am no expert at the fine details of the specifications, so can anyone help here?
