Texas Instruments 德州仪器 RF430F5978 SiP
德州仪器 RF430F5978 系统级封装添加了一个 3D 低频 (LF) 唤醒和应答器接口，此接口与集成了 sub-1-GHz RF 收发器的 CC430 超低功耗微控制器片上系统 (SoC) 连接。为了在整个系统内延长电池的使用寿命，这个架构可在一个专门而明确的“按需”区域内实现器件的激活和关闭。此嵌入式 LF 应答器接口即使在没有电池供电的情况下仍可工作，并且通过其 128 位 AES 加密功能为查问/应答和相互认证提供最高级别的安全保护，它还在系统中添加了 2kB 的可编程 EEPROM 存储器。CC430 超低功耗微控制器片上系统 (SoC) 将 CC1101 sub-1-GHz RF 收发器与功能强大的 MSP430™ 16 位精简指令集 CPU 结合在一起。16 位寄存器和常数发生器有助于实现最大的代码效率。它配备了 MSP430 CPUXV2、32kB 系统内可编程闪存、4kB RAM、2 个 16 位定时器、一个高性能 12 位模数 (A/D) 转换器（带 6 个外部输入加上内部温度和电池传感器）、比较器、通用串行通信接口 (USCI)、128 位 AES 安全加速器、硬件乘法器、DMA、支持闹铃功能的实时时钟模块。RF430F5978 将微控制器内核、其外设、软件以及唤醒和应答器接口用集成型 sub-1-GHz RF 收发器和 3D LF 收发器紧密地集成在一起，让这些解决方案在提升性能的同时方便了使用。
The CC430 ultra-low-power microcontroller system-on-chip (SoC) combines the CC1101 sub-1GHz RF transceiver with the powerful MSP430™ 16-bit RISC CPU. 16-bit registers and constant generators contribute to maximum code efficiency. It features the MSP430 CPUXV2, 32kB of in-system programmable flash memory, 4kB of RAM, two 16-bit timers, a high-performance 12-bit analog-to-digital (A/D) converter with six external inputs. It also features internal temperature and battery sensors, a comparator, universal serial communication interfaces (USCI), a 128-bit AES security accelerator, a hardware multiplier, DMA, and a real-time clock module with alarm capabilities.
The Texas Instruments RF430F5978 provides tight integration between the microcontroller core, its peripherals, software, and the integrated sub-1GHz RF transceiver and 3D LF transceiver for wake-up and transponder interface, making these solutions easy to use while improving performance.
