Folks, I would like to use the 8051 derivate MAXIM DS89C4xx in one of my experiments regaring motor controlling but I am worried about the on-chip debugging capabilites. I could not find any material on this topic. Does anybody know whether the DS89C4xx series support debugging or not? Any other known 8051 derivate which features on-chip debugging and which offers an evaluation bo...

I am looking for a circuit simulation software, so that I can make a circuit using ds89c430 microcontroller, simulate/check and then purchase the parts and make a kit. Can you please let me know, which circuit simulation software is good, and supports 8051 microcontrollers. Better if open source / free circuit simulation software.

Released under GPL2: An 8051-8052 2 pass assembler for the Linux OS. http://panteltje.com/panteltje/newsflex/a52-2.0.tgz This is a very simple assembler, and has less features then all the big macro ones. But it has one feature all other ones do not have as far as I know: It can generate binary output in MCS-52 BASIC data statements. this makes writing inline asm easy in MCS-BASIC. For ex...

Watch this space (if you're interested). Partisanship and nepotism definitely encouraged on this one... I'm going to be unloading a boatload of electronic parts and equipment very soon. CHEAP. As in, a $50 steak dinner and you pick up the shipping. Ideal purchaser, and my strong preference: An EE or similar student. I'll inventory it all this weekend. It's mostly 8051-derivatives dev...

Hi All, Ok, going crazy (short trip, I know...) A few months ago, I saw an article that included information on delta sigma DACs, inlcuding some code the author had written, I belive for an 8051, to implement one in software. So, now that I finally want to try it out, I can't find it anywhere. Anyone know what magazine or have a link to that article? I thought it was in EDN, but can't f...


8051F020 series, 5V tolerant input schematic?

Folks, Got a Silicon Labs 8051Fxxx with 5V-tolerant ports. In the abs max it says 5.8V is the limit. Well, if one uses the typical diode against the 5V rail it could go slightly above 6V in case of a really big jolt. Since this 8051 does not have a 5V supply but just VDD (which hangs on 3.3V in this case) there can't be any parasitic substrate diodes dumping into a rail. Does anyone kno...

I've never used an 8051/8052, but have used other uCs. I have an 8052 comp= atible chip in a commercial product that has a defective pin, and I'm tryin= g to figure out if I could possibly read the firmware from it and replace i= t. In other words, is it code protected. The original is made by Winbond, now Nuvoton, part w78e052c40dl. It would = be nice if I could figure out if it's code ...

Any rules of thumb about sending a 9600 baud UARTsignal ,from an 8051 through a telecom type V90 audio transformer, (LT spice K L1 L2 1 @ 4mH Rs = 10R) I only need about 8 bytes of data, and LTspice seems to need a square wave for about a millisecond before it settles down. So a long sync word of 010101 etc then a start byte? I'll pad the sig down to 100mV or so martin

Does anyone know if there is an alternative device similar to the Atmel FPSLIC (AVR +FPGA)? I would like something like an 8051 derivative that has some built in configurable programmable logic. The Atmel parts are nice, but overkill for my application. They are also somewhat expensive. My requirements are a bit loose at the moment and I'm searching for a slick approach to a floppy emul...

Hi all, I want to log the number of pulse from a device and store the count in a non volatile memory. I am going to use 89c52 microcontroller. The problem is I will log the data for a long time , so the internal memory is not sufficient. How can I add a non volatile external memory to micro 89c52 in hardware. What is the procedure to send data to the addresses of this external memory? Th...
