DC CHARACTERISTICS
Standard Operating Conditions: 3.0V to 3.6V
(unless otherwise stated)
Operating temperature -40°C  TA  +85°C for Industrial
-40°C  T
A  +125°C for Extended
Parameter No. Typ. Max. Units Conditions
DC61d 8 — A-40°C
3.3V
DC61a 10 — A +25°C
DC61b 12 — A +85°C
DC61c 13 — A +125°C
Note 1: The I
WDT current is the additional current consumed when the module is enabled. This current should be
added to the base I
PD current. All parameters are characterized but not tested during manufacturing.

Note 1: I
DOZE is primarily a function of the operating voltage and frequency. Other factors, such as I/O pin loading
and switching rate, oscillator type, internal code execution pattern and temperature, also have an impact
on the current consumption. The test conditions for all I
DOZE measurements are as follows:
• Oscillator is configured in EC mode and external clock is active, OSC1 is driven with external square
wave from rail-to-rail (EC clock overshoot/undershoot < 250 mV required)
• CLKO is configured as an I/O input pin in the Configuration Word
• All I/O pins are configured as inputs and pulled to V
SS
•MCLR = VDD, WDT and FSCM are disabled
• CPU, SRAM, program memory and data memory are operational
• No peripheral modules are operating; however, every peripheral is being clocked (all PMDx bits are
zeroed)
• CPU is executing while(1) statement
• JTAG is disabled
