What is the use of MAX7128?

[Kelvin]

Hi, there:

I saw some boards with a EPM7128SLC84...which I found can only implement a
simple 8-bit multiplier...
For example, http://www.fpga.com.cn/solution/jx002b.htm ...

Is there any market for such tiny FPGA chips? What are they?

The salient feature in non-volatility not capacity.
Some logic has to work immediately at powerup.
Maybe some glue to boot a cpu or to control the loading of fpgas.

Well, #1 is that it's a CPLD. #2 is that a 128-macrocell CPLD was
certainly sufficient for me to use as the controller for a audio
digital delay. I2S in, I2S out, SRAM controller, digital input level
meter, the works.

Not every design needs that multi-million-gate thousand-ball
thousand-dollar FPGA, ya know. Betcha that brands A, L and X sell
more of the small/midsize CPLDs than they do of the
super-big/super-fast devices.

anyway, some chinese laboratories are selling EPM7128SLC84 boards for
50US$...targetting
the college students there...It looks impressive but I don't know how it
competes with other board...
