特征

低功耗

11种低功耗模式，提供电源和时钟门控电路，可以获得优选的外设操作和恢复时间。停止模式唤醒时间为4 µs。
工作电压降至1.71 V时，仍可实现完整的存储器和模拟操作，延长了电池使用时间
低漏电唤醒单元，带有多达8个内置模块和16个引脚，可作为低漏电停止(LLS)模式/超低漏电停止(VLLS)模式的唤醒源
低功耗定时器支持系统在低功耗状态下持续运行

闪存、SRAM和FlexMemory

128 KB-512 KB闪存。快速访问、高可靠性，提供4级安全保护
64 KB的FlexRAM
- 4 KB用户可分段的字节写入/擦除EEPROM，适用于数据表/系统数据。
- 可擦写10M次以上的EEPROM和写入时间仅100微秒的闪存(出现电力故障时不会发生数据丢失或损坏)。
- 无需用户或系统干预便可完成编程和擦除功能，工作电压降至1.71V时仍可完全工作。
- 此外，64 KB的FlexNVM还用于额外程序代码、数据或EEPROM备份。

性能

50 MHz Arm^{^®} Cortex^®-M4内核，带有DSP指令集、单周期MAC和单指令多数据(SIMD)扩展。
多达16通道的DMA用于外设和存储器，可以降低CPU负载，实现更快的系统吞吐
交叉开关支持并发多主设备总线访问，增加总线带宽

定时和控制

两个FlexTimer，共有10个通道。硬件死区时间插入和正交解码，用于电机控制
载波调制定时器，用于在遥控应用中生成红外线波形
4通道32位周期中断定时器可为实时操作系统任务调度程序提供时基，还可为ADC转换和可编程延迟模块提供触发源

数据连接与通信

多达3个UART。一个UART支持带流量控制功能的RS232、RS485、ISO7816和IrDA。其他两个UART支持带流量控制功能的RS232和RS485
一个IC间音频传输(I²S)串行接口，用于接入音频系统
一个DSPI和一个I²C

可靠性、功能安全和信息安全

硬件加密协处理器用于确保数据传输和存储的安全。比软件实施速度更快，CPU负载更低。支持各种算法 - DES、3DES、AES、MD5、SHA-1、SHA-256
具有系统安全和篡改检测功能，采用带有独立电池的实时时钟。安全的密钥存储带有内部/外部篡改检测功能，适用于不安全的闪存、温度、时钟、电源电压变化和物理攻击检测等
循环冗余校验引擎可验证存储器内容和通信数据，提高系统可靠性
时钟独立的COP可防止时钟偏移或代码失控，适用于故障安全型应用(例如，针对家用电器的IEC 60730安全标准)
如果发生看门狗事件，外部看门狗监控器可将输出引脚置于安全状态外部组件
