RF430F59xx MSP430 SoC With Radio-Frequency Core and Low-Frequency Interface



The TI RF430F5978 system-in-package adds a 3D low-frequency (LF) wake-up and transponder interface to the CC430 ultra-low-power microcontroller system-on-chip (SoC) with integrated sub-1-GHz RF transceiver. This architecture allows activation and deactivation of the device in a dedicated and well-defined area "on-demand" to achieve extended battery life for the whole system. The embedded LF transponder interface is always functional even without battery supply and offers the highest level of security through its 128-bit AES encryption for challenge/response and mutual authentication. The embedded LF transponder interface also adds 2KB of programmable EEPROM memory to the system.

The CC430 ultra-low-power microcontroller system-on-chip (SoC) combines the CC1101 sub-1-GHz RF transceiver with the powerful MSP430 16-bit RISC CPU. Sixteen-bit registers and constant generators contribute to maximum code efficiency. The RF430F5978 device features the MSP430 CPUXV2, 32KB of in-system programmable flash memory, 4KB of RAM, two 16-bit timers, a high-performance 12-bit ADC with six external inputs plus internal temperature and battery sensors, a comparator, two USCIs, a 128-bit AES security accelerator, a hardware multiplier, DMA, and an RTC module with alarm capabilities.

The RF430F5978 provides a tight integration between the microcontroller core, its peripherals, software, and the integrated sub-1-GHz RF transceiver and 3D LF transceiver for wake-up and transponder interface, making these solutions easy to use while improving performance.
