Consum al unui mcu

[spinach]

Am o problema globala de cosum energeti:ma refer la 2413, mega8,mega48

In toate pasapoartele este notificat un consum pt 8Mhz.

1.nu inteleg in ce conditii de periferie sint notificate valorile ;sistemul analogic ? timerii ?

2.ce se intimpla daca merge la 20 Mhz ?

3.pe hirtie pare ca 2313 consuma mai putin decit mega8 . In conditiile ca nu folosesc deloc analogic , au consumuri comparabile ?

Nu stiu in ce DS citesti tu ce ai scris, insa te invit sa citesti pag 242 - 256 de aici: http://www.atmel.com/Images/Atmel-2486-8-bit-AVR-microcontroller-ATmega8_L_datasheet.pdf (saunt cam aceleasi date si pentru ATmega48).

Si inca ceva, Atmel nu are intre produsele sale vreun uC "2413" ci doar 2313, dar asta este altceva.

Pentru ATtiny2313 studiaza paginile 207 - 2014 din DS: http://www.atmel.com/images/doc8246.pdf

L.E.: Asta citesti la pag.206 (ATTiny2313) : "All current consumption measurements are performed with all I/O pins configured as inputs and with internal pull-ups enabled. Current consumption is a function of several factors such as operating voltage, operating frequency, loading of I/O pins, switching rate of I/O pins, code executedand ambient temperature. The dominating factors are operating voltage and frequency."

Acelasi lucru il poti citi la pag.244 (ATMega8).

Da. Am inteles .

Daca activez o cale de reducere consum , tip idle , cit as putea obtine reducere ?
