Typical data retention values are based on measured response accelerated at high temperature and derated to a constant 25C use profile. Engineering Bulletin EB618 does not apply to this technology. Typical endurance defined in Engineering Bulletin EB619. 2. Cycling endurance represents number of program/erase cycles at -40C Tj 125C. 3. Write endurance represents the number of writes to each FlexRAM location at -40C Tj 125C influenced by the cycling endurance of the FlexNVM (same value as data flash) and the allocated EEPROM backup. Minimum and typical values assume 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 flash memory module 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 is 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 TSI module is functional with capacitance values outside this range. However, optimal performance is not guaranteed. 2. Fixed external capacitance of 20 pF. 3. REFCHRG = 2, EXTCHRG=0. 4. REFCHRG = 0, EXTCHRG = 10. 5. VDD = 3.0 V. 6. The programmable current source value is generated by multiplying the SCANC[REFCHRG] value and the base current. 7. The programmable current source value is generated by multiplying the SCANC[EXTCHRG] value and the base current. 8. Measured with a 5 pF electrode, reference oscillator frequency of 10 MHz, PS = 128, NSCN = 8; Iext = 16. 9. Measured with a 20 pF electrode, reference oscillator frequency of 10 MHz, PS = 128, NSCN = 2; Iext = 16. 10. Measured with a 20 pF electrode, reference oscillator frequency of 10 MHz, PS = 16, NSCN = 3; Iext = 16. 11. Sensitivity defines the minimum capacitance change when a single count from the TSI module changes. Sensitivity depends on the configuration used. The documented values are provided as examples calculated for a specific configuration of operating conditions using the following equation: (Cref * Iext)/( Iref * PS * NSCN) The typical value is calculated with the following configuration: Iext = 6 A (EXTCHRG = 2), PS = 128, NSCN = 2, Iref = 16 A (REFCHRG = 7), Cref = 1.0 pF The minimum value is calculated with the following configuration: Iext = 2 A (EXTCHRG = 0), PS = 128, NSCN = 32, Iref = 32 A (REFCHRG = 15), Cref = 0.5 pF The highest possible sensitivity is the minimum value because it represents the smallest possible capacitance that can be measured by a single count. 12.
