In the NXP Data Sheet for the LPC176x family processors of Feb/2009 there were extensive charts of Peripheral Current Consumption requirements. Unfortunately, all the entries were empty, and populated with <TBD>. See Table 7, Page 45.
When the Dec/2009 Data Sheet was released, all these tables were gone, and the only Power Requirements listed were for the Core, in the Static Characteristics table. And these stats specifically indicate "With all peripherals disabled". Since disabling all the peripherals makes the MCU pretty useless, this is a strange oversight. Knowing that the chip pulls 67 mA at 100 MHz, with all peripherals turned off isn't very useful. Surprisingly, the User Manual for the LPC176x family has no Power information at all.
I just downloaded the latest, July16'10 Data Sheet, and there's nothing there either, that I can see. Does NXP now have data on Peripheral Current Consumption, that perhaps simply hasn't made it into the Data Sheets? Thanks!
