Please quantify for 32kHz clock and the lowest supply voltage at full run for the equivalent of PIC16F84, at least as a typical value (it's typ 15uA for the PIC).

Such figures are not really meaningfull. Total consumption depends critically on the state of inputs and outputs and the loads they are attached to. I know I was bitten that way once. We developed a CO monitor using a Z8. We got lots of info fron Zilog about the current consumption and determined we could achieve the required 5 year battery life and 15 uA current consumption. Unfortunately the first 50,000 mask programmed types consumed nearly 10 times this value - why because we had not chosen the correct output states nor did we realise their significance in terms of total power consumption. Of course the OTP parts we used for development were NOT identical to the ROM parts so this may be less of an issue today with identical flash parts in development and production but I would advise you to tread extremely carefully.

   Datasheets are terrible...            01/01/70 00:00      
   I hear you brother!            01/01/70 00:00      
      to PIC or not to PIC            01/01/70 00:00      
      8051-like "instruction set" for PICs            01/01/70 00:00      
   Why PICs? Let me count the ways            01/01/70 00:00      
      Hey Charles!            01/01/70 00:00

               PICs are low consumption            01/01/70 00:00      
                  ...So are LPC            01/01/70 00:00      
                     how much exactly?            01/01/70 00:00      
                         Not at the moment            01/01/70 00:00      
                        did you check the \"user giude\"?            01/01/70 00:00      
                           that's even more confusing            01/01/70 00:00

      PICs outsell the 8051??            01/01/70 00:00      
         Both outsold by 68HC05            01/01/70 00:00      
      a comment and a correction            01/01/70 00:00      
      All these wonders, yet the 805x still outsells it!            01/01/70 00:00      
      Market share            01/01/70 00:00      
      Lots of 8051s now            01/01/70 00:00
