External RAM of 89S51 is complicated! Like Richard says, that's the way it is with the 8051 Architecture - if you don't find it acceptable, then you will need to switch to a different Architecture! (but you will undoubtedly find that other architectures have their own foibles!) Is there any microcontroller which is has huge internal RAM in it? Depends what you mean by "internal". The DATA and IDATA address spaces[1] sizes are fixed by the 8051 Architecture, but there are plenty of chips with large amounts of on-chip XDATA - See: http://www.keil.com/dd/search_parm.asp [1]: I'm using the terms DATA, IDATA, and XDATA as used by Keil: http://www.keil.com/support/m...atamem.htm http://www.keil.com/support/m...atamem.htm |

Yes, but they handle it the same as external RAM  | Richard Erlacher | 01/05/10 22:38 |

| It's Not Really So Complicated--And.... | Marty McLeod | 01/06/10 16:25 |
| someone recently posted a link to a 805x with 64kB of RAM | Richard Erlacher | 01/06/10 16:34 |
| Proper methodology can't really bound the memory requirement | Per Westermark | 01/06/10 17:56 |
That's My Point | Marty McLeod | 01/13/10 20:21 |
| RAM expansion need not be complicated! | Valentin Angelovski | 01/06/10 18:37 |
| MOVX problem | Trangga Findanugroho | 01/06/10 22:20 |
| No | Per Westermark | 01/06/10 22:29 |
| unless you have external glue logic | Andy Neil | 01/07/10 01:46 |
| Yes | Per Westermark | 01/07/10 03:06 |
| "bible" time! | Andy Neil | 01/07/10 01:53 |
| There are much larger SPI memories | Richard Erlacher | 01/07/10 01:39 |
| Look at Wiz chip | JecksonS Ben | 01/07/10 05:14 |

| How does that compare with ordering from outside? | Richard Erlacher | 01/12/10 08:13 |
