Security circuitry to prevent unauthorized access to RAM and flash contents
• Power-Saving Modes
Two low-power stop modes (stop2 and stop3)
Reduced-power wait mode
Peripheral clock gating register can disable clocks to unused modules, thereby reducing currents
Low power on-chip crystal oscillator (XOSC) that can be used in low-power modes to provide accurate clock source to real time counter and LCD controller

Hysteresis and configurable pullup device on all input pins;configurable slew rate and drive strength on all output pins.
• Package Options
48-pin LQFP, 64-pin LQFP, and 80-pin LQFP

1 Input must be current limited to the value specified. To determine the value of the required current-limiting resistor, calculate resistance values for positive (V_DD) and negative (V_SS) clamp voltages and use the largest of the two resistance values.

2 All functional non-supply pins are internally clamped to V_SS and V_DD.

3 Power supply must maintain regulation within operating V_DD range during instantaneous and operating maximum current conditions. If positive injection current (V_In > V_DD) is greater than IDD, the injection current may flow out of V_DD and could result in an external power supply going out of regulation. Ensure that the external V_DD load will shunt current greater than maximum injection current, this will be of greater risk when the MCU is not consuming power. For instance,If no system clock is present, or if the clock rate is very low (which would reduce overall power consumption).
