## Features
### Low-Power
* 11 low-power modes with power and clock gating for optimal peripheral activity and recovery times. 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-512 KB flash. Fast access, high reliability with 4-level security protection
* Up to 64 KB FlexRAM
* FlexMemory
* Up to 4 KB of user-segmentable byte write/erase EEPROM for data tables/system data
* EEPROM with over 10M cycles and flash with 100 µsec write time (brownouts without data loss or corruption)
* No user or system intervention to complete programming and erase functions and full operation down to 1.71 volts
* In addition, FlexNVM from 64 KB for extra program code, data or EEPROM backup
### Performance
* 50 MHz ARM Cortex-M4 core with DSP instruction set, single cycle MAC and single instruction multiple data (SIMD) extensions
* Up to 16-channel DMA for peripheral and memory servicing with reduced CPU loading and faster system throughput0 MHz core
* Cross bar switch enables concurrent multi-master bus accesses, increasing bus bandwidth
### Timing and Control
* Up to two FlexTimers with a total of 10 channels. Hardware dead-time insertion and quadrature decoding for motor control
* Carrier modulator timer for infrared waveform generation in remote control applications
* Four-channel 32-bit periodic interrupt timer provides time base for RTOS task scheduler or trigger source for ADC conversion and programmable delay block
### Connectivity and Communications
* Up to three UARTs. One UART supports RS232 with flow control, RS485, ISO7816 and IrDA. All other two UARTS support RS232 with flow control and RS485
* One inter-IC Sound (I²S) serial interface for audio system interfacing
* One DSPI and one I²C
### Reliability, Safety and Security
* Cyclic redundancy check engine validates memory contents and communication data, increasing system reliability
* Independent-clocked COP guards against clock skew or code runaway for fail-safe applications such as the IEC 60730 safety standard for household appliances
* External watchdog monitor drives output pin to safe state external components if watchdog event occurs
