特征

超低功耗

10种低功耗模式，提供电源和时钟门控，可以实现优选的外设活动和恢复时间。停止电流<500 nA、运行电流<200 uA/MHz、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

512 KB - 1 MB闪存。支持快速访问，具备高可靠性，提供4级安全保护
128 KB的SRAM
FlexMemory：32字节 - 16 KB的用户可分段字节写入/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70 µs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，128 KB的FlexNVM还可用于额外程序代码、数据或EEPROM备份

混合信号功能

最多两个分辨率可配置的高速16位模数转换器(ADC)。单输出或差分输出模式运行，可提高噪声抑制水平。利用可编程延迟模块触发功能可实现500 ns的转换时间
多达两个12位数模转换器(DAC)，可以为音频应用生成模拟波形
3个高速比较器，通过将脉宽调制(PWM)置于安全状态，提供快速准确的电机过流保护
模拟参考电压可为模拟模块、ADC和DAC提供精确的参考值，代替外部参考电压，降低系统成本

性能

Arm^{^®} Cortex-M4^®内核 + DSP，120MHz，单周期 MAC，单指令多数据(SIMD)扩展，单精度浮点运算单元
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
独立的闪存Bank可以并发执行代码和固件更新，既不会影响性能，也无需复杂的编码例程

定时和控制

多达4个FlexTimer，总计20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

人机接口(HMI)

多达16个可控通用IO，支持引脚中断

连接与通信

USB 2.0 OTG (全速)。设备充电检测优化了便携式USB设备的充电电流/时间，延长了电池使用时间。低压稳压器可通过5V输入为外部组件提供高达120 mA，3.3V的片外供电
多达6个支持IrDA的UART，其中一个UART支持ISO7816智能卡。支持各种数据大小、格式和传输/接收设置，满足多种工业通信协议
IC间音频传输(I²S)串行接口，用于接入音频系统
CAN模块，适用于工业网络桥接
多达3个DSPI和两个I²C

安全性

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

可靠性、功能安全和信息安全

存储器保护单元可为交叉开关上的所有主设备提供存储器保护，提高软件可靠性
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
