All functional non-supply pins are internally clamped to VSS and VDD. Input must be current limited to the value specified. To determine the value of the required current-limiting resistor, calculate resistance values for positive and negative clamp voltages, then use the larger of the two values. Power supply must maintain regulation within operating VDD 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 clock rate is very low (which would reduce overall power consumption).

Typical data retention values are based on intrinsic capability of the technology measured at high temperature derated to 25°C. For additional information on how Freescale defines typical data retention, please refer to Engineering Bulletin EB618. 2. Data retention is based on Tjavg = 55°C (temperature profile over the lifetime of the application). 3. Cycling endurance represents number of program/erase cycles at -40°C ≤ Tj ≤ 125°C 4. Write endurance represents the number of writes to FlexRAM at -40°C ≤Tj ≤ 125°C influenced by the cycling endurance of the FlexNVM (same value as data flash) and the allocated EEPROM backup per subsystem. Minimum value assumes all byte-writes to FlexRAM. 6.4.1.5 Write Endurance to FlexRAM for EEPROM When the FlexNVM partition code is not set to full data flash, the EEPROM data set size can be set to any of several non-zero values. The bytes not assigned to data flash via the FlexNVM partition code are used by the FTFL to obtain an effective endurance increase for the EEPROM data. The built-in EEPROM record management system raises the number of program/erase cycles that can be attained prior to device wear-out by cycling the EEPROM data through a larger EEPROM NVM storage space. While different partitions of the FlexNVM are available, the intention is that a single choice for the FlexNVM partition code and EEPROM data set size are used throughout the entire lifetime of a given application. The EEPROM endurance equation and graph shown below assume that only one configuration is ever used.

The analog source resistance (RAS), external to MCU, should be kept as minimum as possible. Increased RAS causes drop in PGA gain without affecting other performances. This is not dependent on ADC clock frequency. 5. The minimum sampling time is dependent on input signal frequency and ADC mode of operation. A minimum of 1.25µs time should be allowed for Fin=4 kHz at 16-bit differential mode. Recommended ADC setting is: ADLSMP=1, ADLSTS=2 at 8 MHz ADC clock. The ADLSTS bits can be adjusted for different ADC clock frequency 6.6.1.4 Symbol IDDA_PGA ILKG G 16-bit ADC with PGA characteristics Table 26. 16-bit ADC with PGA characteristics Description Supply current Leakage current Gain2 PGA disabled Conditions Min.
