Signetics make the 68070. It is roughly a 68000 clone with some on board goodies like DMA, serial ports, and some other things.

It only has one accumulator which it must share for both normal stuff + address calculations. Some of the instructions with the fancier addressing modes approach 1/2 the speed of a 68k. Another 68k clone that uses the same core as Moto (2nd source) and is cmos and has 3 uarts, 3 timers, bus timing features + general I/O (like centronics support) but no DMA is made by Toshiba - TMP68301. regards, -- George Scolaro george@wombat.bungi.com [37 20 51 N / 122 03 07 W]

They've got timers, dmas, async and synchronous communications ports and protocols, all built into the chips. I believe the two announced parts are the 68302 and the 68332.

Check 'em out! >-- I just picked up my 68332 evaluation board this afternoon and got it running. It looks like it'll be a pretty good platform for evaluating the part. One problem I've noticed alread though, is that the internally generated chip selects for the on-board RAM use the pins that have the alternative functions ~BG, ~BR and ~BGACK. My first anticipated use for this thing was to try to interface it with the NCR 53C700 SCSI chip - which should become a bus-master for maximum speed. The documentation seems to indicate that you can work around this by adding additional off-board RAM and then disabling (wasting!) 32K x 16 worth of 35 nS static RAM! (And the documentation for making changes to the board are sketchy.) Does anyone from Motorola read this group? I would be delighted to find that I'm incorrect. -- |---------------------------------------------------------------| | // Wayne D.

The 68070 is manufactured by Philips, but in the USA it is sold by Signetics (a division of North American Philips Corp.). I have both the data sheet and User's manual in front of me as I type this, and the main name on the data sheet is Philips (every page) but the back cover belongs exclusively to Signetics. The only mention of Philips on the back is in small letters stating that Signetics is owned by Philips. Everybody is right about who makes the 68070 (unless you said Intel :-) -dave
