Electrical Characteristics

All VSSX pins are internally connected by metal.

VDDA, VDDX and VSSA, VSSX are connected by diodes for ESD protection.

NOTE

In the following context VDD35 is used for either VDDA, VDDR, and

VDDX; VSS35 is used for either VSSA and VSSX unless otherwise noted.

IDD35 denotes the sum of the currents ï¬owing into the VDDA, VDDX and

VDDR pins.

A.1.3 Pins

There are four groups of functional pins.

A.1.3.1 I/O Pins

The I/O pins have a level in the range of 3.13V to 5.5V. This class of pins is comprised of all port I/O pins,

the analog inputs, BKGD and the RESET pins. Some functionality may be disabled.

A.1.3.2 Analog Reference

This group consists of the VRH pin.

A.1.3.3 Oscillator

The pins EXTAL, XTAL dedicated to the oscillator have a nominal 1.8V level.

A.1.3.4 TEST

This pin is used for production testing only. The TEST pin must be tied to ground in all applications.

A.1.4 Current Injection

Power supply must maintain regulation within operating VDD35 or VDD range during instantaneous and

operating maximum current conditions. If positive injection current (Vin > VDD35) is greater than IDD35,

the injection current may ï¬ow out of VDD35 and could result in external power supply going out of

regulation. Ensure external VDD35 load will shunt current greater than maximum injection current. This

will be the greatest risk when the MCU is not consuming power; e.g., if no system clock is present, or if

clock rate is very low which would reduce overall power consumption.

A.1.5 Absolute Maximum Ratings

Absolute maximum ratings are stress ratings only. A functional operation under or outside those maxima

is not guaranteed. Stress beyond those limits may affect the reliability or cause permanent damage of the

device.
