#172204 - It's Not Really So Complicated--And.... Responding to: Trangga Findanugroho's previous message |
It's not really that complicated, relatively speaking. As the post above suggested, you need to remember that it is because it is based on the old 8051 architecture. Yes, you CAN get large internal memory, but based on what constraints? What is the correct part for your application? What are your clearly defined requirements for hardware and software? 32K (or less!) RAM is more than enough in some larger applications. Even 8K or whatever is sufficient when applied properly and when you've clearly defined your design requirements and are using proper software programming methodology. We ran a whole board successully with one Silicon Lab. 8051 w/ 4K XRAM. |

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

| 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 |
| Link? | Andy Neil | 01/07/10 05:44 |

| Overkill? | Andy Neil | 01/07/10 07:28 |
| and expensive? | Andy Neil | 01/08/10 02:44 |
| When at electronics store | JecksonS Ben | 01/12/10 06:19 |
| Which one? | Andy Neil | 01/12/10 07:06 |
| How does that compare with ordering from outside? | Richard Erlacher | 01/12/10 08:13 |
| I've always had to do that! | Andy Neil | 01/12/10 09:20 |
