Résistance thermique d'un boîtier Pentium

ftp://download.intel.com/design/pentium4/datashts/29864307.pdf datasheet des Pentium IV ici : Intel était plus loquace pour les versions précédentes; la température de l'air aspiré par le ventilateur type ne doit pas dépasser 40°C (43°C pour les moins rapides) pour les pires conditions de charge du processeur. Comme la température max du processeur est fixée à 75°C, tu peux calculer que l'ensemble doit avoir une résistance thermique de l'ordre de 0,7 K/W. Heureusement, en cas de surchauffe, le processeur s'auto-protège en ralentissant certaines de ses horloges.

Il existe toujours des microcontrôleurs compatible 80186 par exemple le NEC V25, AMD avait aussi quelques microcontrôleurs dans la famille 186 (maintenant obsolète). Ces microcontrôleurs délicats (chercher "locater" pour plus d'info). Mais bon à environ 8 MHz ça ne pédale pas très vite pour envoyer les pixels... Et puis la segmentation du x86 n'est pas toujours évidente.

The µFlashTCP packs a 386 DOS computer and 10Base-T Ethernet onto a board slightly larger than a credit card. This is an ideal platform for bridging existing equipment to Ethernet networks. PC compatible serial ports and bit I/O make system integration a snap. The µFlashTCP is also a good choice for new embedded designs requiring network connectivity. The powerful processor, NE2000 compatible Ethernet, and DOS operating system allow design and debugging in a familiar environment.

The µFlashTCP Development Kit (99-0029) includes µFlashTCP with 512KRam/512KFlash, Connector Kit, Ethernet Cables, 110 VAC Adapter, Users Manual, and Borland C/C++ V4.52 Compiler. (220Vin to 110V transformer (70-0006) available.)

Also included are sample programs and source code for the TCP/IP stack and web server that can be compiled with the Borland C/C++ package.


http://www.tern.com/ ... manufacturer and designer of 16/32-bit x86 embedded solutions ... This site is your guide to all of TERN's various hardware and software solutions! Here you can find descriptions of new TERN products, detailed pricing information, and answers to your nagging technical questions. The menu you find near the top of every page can be used to easily navigate this site. Please contact us with any concerns or problems you might have.

TERN controllers are designed for embedded systems that require high performance, PC-compatibility, compactness, low power consumption, and high reliability at a low cost. They can be integrated into an OEM product as a processor core omponent. They also can be used to build a smart sensor, or as a node in a distributed microprocessor systems. By building your product around TERN controllers, you reduce the time from design to market introduction, cut development costs, minimize technical risks, and deliver a more reliable product.Our complete embedded controller product line includes i386EX, Am188ES, and V25-based controllers with ADC, DAC, real-time clock, EEPROM, solenoid drivers, power relays, UARTs, opto couplers, LCDs, keypads, PCMCIA, Flash, 9-bit networking, and quadrature decoders. Up to 220 MB memory space can be supported with the MemCard™ using PCMCIA Flash cards. ACTF™ Flash support allows you to download a program to Flash without burning ROMs.
Even with our wide range of available controllers, we know we might not have exactly what you are looking for. If you have specific application requirements in mind, and our listed controllers do not match them exactly, contact us for information about custom board design. After initial prototypes, custom controllers are priced similarly to our current product line.

All of TERN's controllers are designed and manufactured within the USA.
