i want to design a small system of 5402 but i have a problem on extending flash and sram i am not very sure the logic relation between dsp and flash is that right? /PS || /MSTRB connect with SRAM 's /CE pin R//W connect with SRAM 's /OE pin through a NOT gate R//W connect with SRAM 's /WE pin /DS || /MSTRB connect with SROM 's /CE pin R//W connect with SROM 's /OE pin through a NOT gate R//W connect with SROM 's /WE pin thanks for your watching |

Hi /PS is the program memopry chip select signal and /DS is Data memory chip select signal if u are loading ur code in FLASH then it should have the PS and not DS. similarly if u are storing ur data in SRAM then it should have DS. you can directly connect /PS to /CE of FLASH. regards vinodh -----Original Message----- From: dance007_0 [mailto:] Sent: Tuesday, February 17, 2004 8:17 AM To: Subject: [c54x] HELP! how to extend flash and sram i want to design a small system of 5402 but i have a problem on extending flash and sram i am not very sure the logic relation between dsp and flash is that right? /PS || /MSTRB connect with SRAM 's /CE pin R//W connect with SRAM 's /OE pin through a NOT gate R//W connect with SRAM 's /WE pin /DS || /MSTRB connect with SROM 's /CE pin R//W connect with SROM 's /OE pin through a NOT gate R//W connect with SROM 's /WE pin thanks for your watching _____________________________________ Note: If you do a simple "reply" with your email client, only the author of this message will receive your answer.
