PALCE Chips

Hi,

I usually just use GAL's and write in wincupl. For what I use them for
they work fine. PALCE chips, I've found an affordable programmer, the
TOP 3000 that can write to them. However, I am not sure if I can continue
to use wincupl or if I need to learn how to use PALASM.
Anyone know programming language works with what chips?

regards

As I recall, PALCE chips were functionally the same as their GAL equivalents. I think the jedec files are compatible

I'm 99% sure I used PALCE chips at some point, and if so I would definitely have used CUPL/WINCUPL

Some part numbers would help.

WinCUPL supports the mainstream 16V8 / 22v10, which covers most parts up to 10 macrocells. WinCUPL runs fine here in Win100 in command line mode.

Then, you have ATF750, with 20 macrocells, and ATF2500 and ATF1502/4/8 parts.
The ATF1502/4/8 use JTAG ISP, so are easier to use, and most users 'skip over' the ATF750 & ATF2500, which have more sparse programmer support.
ATF750 is useful if you have an existing 22V10 footprint that needs a bit more logic packed in.

It's a whole series of chips. I've managed to get hold of the software for the top
Programmer from 2022, but to get the 2023 edition you need to register on a Chinese
Website.

The 22V10 all have the same logic fuses, some have an extra optional 64 bits of user signature, and some Atmel parts have a power down bit.

Atmel's CUPL info says this

Table 10-1. Compiler Mode Selection
PAL Mode   (5828 Fuses)      GAL Mode    (5892 Fuses)    Power-down Mode(1) (5893 Fuses)
WINCUPL    P22V10 P22V10LCC  G22V10 G22V10LCC            G22V10CP    G22V10CPLCC
