#101910 - Huge RAM, why ? Responding to: ???'s previous message |
Jeff Corr said:
Well ultimately I liked the idea of using the SBC as a control for a robotic application, and the idea of tons of external ram makes it even more appealing; On my practice the needed amound of SRAM was typically enormeous overrated. Most projects can work inside 128 byte (I program always in C). And most today devices are 8052 derivates (256 bytes RAM) and some with additional internal XRAM (Atmel: 2kB). My biggest project was now updated in this way, that the P80C652 with external EPROM and SRAM was replaced by the P89C668 with already 8kB RAM internal. Now the board is cheaper and easier to maintenance with this single chip solution as the former tons of chip solution. Today I use no longer external connected SRAM/Flash for new projects. I select always only such derivates with the rigth amount of memory internal. Peter |

| Buy a devboard, they cost about $10. | 01/01/70 00:00 | |
if you build it... | 01/01/70 00:00 | |
