You do realise it costs over a million dollars just for the mask set when making a 0.13u chip, let alone the development costs, packaging etc etc. Chad erikc wrote: > > ----- Original Message ----- > From: "David VanHorn" > To: ; > Sent: Thursday, August 05, 2004 01:38 > Subject:

Sounds intriguing, but the development costs are likely to be astronomical if you're only making 1. Have you considered a Linux cluster? Sure, there's no AVR content, however you should be able to simply assemble and configure a solution. $0.02, Jeff Engel --- Kathy Quinlan wrote

Is it absolutely necessary to connect to GRROUND the back plane connection of the 64 pin MLF package for the ATmega128L package or is this purely for thermal dissipation. what is the effect of not connecting this underside pin to Ground?

Remember that Avcc supplies power to the analog port I/O pins (i.e. if you use them for regular I/O). Even if you only use them for analog inputs, the Schmitt trigger is still active - drawing different current levels for '0' vs '1'. If you use Avcc as your reference and if you h

Hi, lithium polymer battery is does not like sourcing high currents. NiCad's and NiMh's do. May be its better you start with rechargable battery tecnologies and decide the mode of voltage regulation after that. series connection of batteries during charging seems to me more appro
