Can I do MOVX to external serial SRAM? The operation of the MOVX instruction is clearly defined in the 80C51 family programmer’s guide and instruction set document - which is chapter 2 of the so-called "bible" for the 8051: Chapter 1 - 80C51 Family Architecture: http://www.nxp.com/acrobat_d...ARCH_1.pdf Chapter 2 - 80C51 Family Programmer’s Guide and Instruction Set: http://www.nxp.com/acrobat_d...UIDE_1.pdf Chapter 3 - 80C51 Family Hardware Description: http://www.nxp.com/acrobat_d...WARE_1.pdf See also: http://www.8052.com/faqs/120112 |

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

| why? | Stefan KAnev | 01/06/10 12:39 |
| 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 |
| Link? | Andy Neil | 01/07/10 05:44 |
| links | Stefan KAnev | 01/07/10 06:17 |
| 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 |
