'Supply current for PIC16F87x'

Hello list,

I haven't had any replies to my question yet, maybe I didn't ask
nicely enough. Can anyone please quote me some typical
measured values for current consumption on a PIC16F87x device?
Thanks again, Brent.

Brent,

On page 159 of the PIC16F87X databook it talk about the current
consumption. The databook gives typical values of 10mA at 5.5VDC  running
at 20MHz with a MAX of 20mA (HS oscillator configuration). Their isn't
really
that much information in the databook to specific settings.

Best regards,
Steve

 I didn't see your request on the list. The current draw will depend on
your circuit configuration, outputs etc...  Microchip gives typical values
in their data sheets. You can put an ampmeter in series with your power
supply and read the actual/average current draw. Quiescient current will
vary between chips and temperature affects the draw.
Best regards
Mark

Hi Brent,

At room temperature, my 16F877 circuit (with serial EEPROM,
2 ADCs, low dropout regulator, 11.0592MHz osc, PortB pullups
on, WDT off) draws 5.43mA.  In sleep (everything off), it
draws 30.5uA.

Hi Brent....

The front page [first page] of the 87x spec sheet [perfect bound version]
calls for the following:

low-power consumption, < 2 ma typical @ 5V, 4 Mhz.

I recently measured a circuit in which I used the 16F84 and had a total of
10 ma, including LEDs and resistor loads, so 16F84 likely same < 2 ma.

The spec sheets are available on the MCHP website!
