#122651 - Help selecting a 8052 |
I have been developing with a Atmel at89c51ac3. I am running it at 33.3 mhz (Osc) and I have X2 mode enabled. It's in a PLCC 52 package. But...
It not fast enough. The datasheet says it will run at 30 Mhz in x2 mode. So I am already overclocking. Atmel does not have any other fasters chips in the PLCC 42 ot 52 package. I like this chip because of the ISP UART option and 1k or so XRAM. I already have some firmware mostly written. And since I don't have a surface mount soldering iron, it needs to be in a PLCC package. I did look thru the Chips matrix on this site. I found some SiLabs Chips that would work good except there not PLCC. I found other chips that looked good but I can not find a source of small qtys. Any Ideas. Does this mean I need to goto AVR or ARM... My rought calculation are (6 clocks cycles per inst divide 33mhz is about 5.5 million inst per second). I figuare it need to be triple that. |

why not use some shift registers? | 01/01/70 00:00 | |
you need the speed | 01/01/70 00:00 | |
That's PLCC-44, isn't it? | 01/01/70 00:00 | |
