Ultra-Low-Power

• 10 low-power modes with power and clock gating for optimal peripheral activity and recovery times. Stop currents of <500 nA, run currents of <200 µA/MHz, 4 µs wake-up from Stop mode
• Full memory and analog operation down to 1.71 volts for extended battery life
• Low-leakage wake-up unit with up to eight internal modules and 16 pins as 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-1 MB flash. Fast access, high reliability with four-level security protection
• 48-128 KB of SRAM
• FlexMemory: 32 bytes-16 KB of user-segmentable byte write/erase EEPROM for data tables/system data. EEPROM with over 10M cycles and flash with 70 µsec write time (brownouts without data loss/corruption). No user or system intervention to complete programming and erase functions and full operat
