46 / 70 page MC13211/212/213 Technical Data, Rev. 1.2 46 Freescale Semiconductor 6.2 802.15.4 Modem Electrical Characteristics 6.2.1 Modem Recommended Operating Conditions 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 (VDD) and negative (VSS) clamp voltages, then use the larger of the two resistance values. 2 All functional non-supply pins are internally clamped to V SS and VDD. 3 Power supply must maintain regulation within operating V DD range during instantaneous and operating maximum current conditions. If positive injection current (VIn > VDD) is greater than IDD, the injection current may flow out of VDD and could result in external power supply going out of regulation. Ensure external VDD load will shunt current greater than maximum injection current. This will be the greatest risk when the MCU is not consuming power. Examples are: if no system clock is present, or if the clock rate is very low which would reduce overall power consumption. Table 7. Recommended Operating Conditions Characteristic Symbol Min Typ Max Unit Power Supply Voltage (VBATT = VDDINT) 1 1 If the supply voltage is produced by a switching DC-DC converter, ripple should be less than 100 mV peak-to-peak.
