Texas Instruments' 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 de-activation 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, and it also adds 2 kB 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. The 16-bit registers and constant generators contribute to maximum code efficiency. It features the MSP430 CPUXV2, 32 kB of in-system programmable Flash memory, 4 kB of RAM, two 16-bit timers, a high-performance 12-bit analog-to-digital (A/D) converter with six external inputs plus internal temperature and battery sensors, comparator, universal serial communication interfaces (USCI), 128-bit AES security accelerator, hardware multiplier, DMA, and real-time clock module with alarm capabilities.
