• Full memory and analog operation down to 1.71 volts for extendedbattery life
• Low-leakage wake-up unit with up to eight internal modules and 16 pinsas wake-up sources in low-leakage stop (LLS)/very low-leakage stop(VLLS) modes
• Low-power timer for continual system operation in reduced power state
• Flash, SRAM and FlexMemory
• 128 KB - 512 KB flash. Fast access, high reliability with four-levelsecurity protection
• 32 KB-128 KB of SRAM
• FlexMemory: 32 bytes-4KB of usersegmentable byte write/erase EEPROMfor data tables/system data. EEPROM with over 10M cycles and flashwith 70 μsec write time (brownouts without data loss/corruption). Nouser or system intervention to complete programming and erasefunctions and full operation down to 1.71 volts. In addition, upto 256KB can be used for extra program code, data or EEPROM backup
• Mixed-Signal Capability
• Two high-speed 16-bit analog-to-digital converter (ADC) withconfigurable resolution. Single or differential output mode operationfor improved noise rejection. 500 ns conversion time achievable withprogrammable delay block triggering
• Up two 12-bit digital-to-analog converter (DAC) for analog waveformgeneration for audio applications
• Three high-speed comparators providing fast and accurate motorover-current protection by driving PWMs to a safe state
• Analog voltage reference provides an accurate reference to analogblocks, ADC and DAC, and replaces external voltage references toreduce system cost
• Performance
