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 IDOZE 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
