Looking for the right 8051 to use on your next project ?

Computer Solutions has added a powerful self selection search capability to their Micro-Search web-based 8051 microcontroller database, allowing users to specify in detail those features they require in a micro.

MicroSearch, which now includes details of more than 1,000 chips from over

55 manufacturers, allows customised searching for features such as number of I/O pins, number of timers, power consumption, speed and special interfaces supported. As a result, users can match the right micro to their exact needs.

The Self Search Micro-Search reporting facility uses a feature selection form that enables the user to specify the parameters to be displayed in the final report and any requirements on which microcontrollers are to be included.

For example, the user may only be interested in microcontrollers with three external interrupts, more than ten I/O bits and more than 8 Mbyte of flash program space. He might also wish to know their idling power and what packages are available. Once these requirements are entered, the search facility automatically identifies devices that meet the criteria and prints a detailed report.

Micro-Search is part of Comsol's 'Embedded Information Zone', a growing reference directory for designers which can be accessed at

Actually it doesn't. I tried to find 8051 variants with greater than 256 byte stack capability and there was no way to select this.

are there any?

Yes, see the other 8051 thread where someone mentioned a Dallas part with a

10 bit SP and 1K stack memory.

Thanks..

I am also looking for the perfect 8051. But you just can never get everything you want. I noticed that none of the Dallas parts have I2C. A comprehensive site would be handy..

Well,

looking for I2C I would try Philips LPC900.

Looking for higher end 51s with 64k+ memory I would try ARM ;-)

Yes, in exactly the same sense that a frog is derived from cheese.

Yes.. I currently have 3 projects with the LPC932. I need a faster device with more flash than the LPCs can do.

Is the ARM a 51 derivative. ?I know a lot of folks use them but I haven't had one in a project yet.

haven't

that's what I thought. .. well not exactly.

Look on the Keil web site. They have an 8051 search tool. Look carefully for the I2C (trademark Philips) You have to pay to use it. So some companies rename it. (TWI I think)

Agreed, the LPC900 is a very nice family.

For even more speed and memory, but still 8 bits (& cheap), look at the AVR family (especially ATMega types) from Atmel. Not 8051, but worth a look.

Thanks. That's good info.

look.

Yes I have a project with the AVr. But the tools were so bad (Avrstudio).

I use avrgcc. Rowley's IDE is also nice.

SM(System Mangement)Bus is one.

Careful, SMBus != I2C. Same basic protocol, different drive characteristics.

Reply to
larwe

Hmm... Thanks for the update. The datasheet for the (Silicon Labs) micro I'm using describes the SMBus as I2C 'Compatible', but after looking here:

I can see that it is definitely not fully compliant.

How different ? [maybe that's to be more clearly 'not the same bus' ?]
