A few days ago, Texas Instruments (TI) announced the launch of the RF 430F5978 microcontroller (MCU) and supporting assessment module (EVM), further expanding its rich and diverse low-power RF (RF) solution combination camp. RF430F5978 MCU is based on Ti-based CC430 product line, is a highly integrated RF solution that enhances the performance of the read area and the battery, suitable for ultra-low power applications. RF430F5978 MCU includes a 3D low frequency (LF) wake-up and transponder interface, an integrated 1GHz RF transceiver and a programmable MSP430 kernel. The LF transponder can even run in the case where the battery is powered. 128 AES Security Encryption and Decryption Association addresses an advanced security feature for data protection. With its innovative wake-up and positioning RF connections, this highly integrated single-pack system solution can realize a small, compact design with small batteries.
The MCU is ideal for low-power RF applications such as wireless sensor networks, data recorders, active transponders, remote monitoring systems, container tracking, access control, and equipment control and management systems. Using RF430F5978 MCU helps designers to visualize numerous possible applications, product containers data records and wireless communication applications are one of them. When the product container is in a predefined read area, the data recorder based on the RF4305978 MCU can be woken by the LF wake interface on the container, and the program is programmed to transmit a temperature measurement value to the external reader through the RF interface with a frequency lower than 1 GHz. The MCU's secure encryption function can also ensure that any information read or transmit only enters or from a specified and authorized reader.
New EVM and supporting software can achieve leapfrog development
To evaluate the RF430F5978 MCU system, developers can purchase RF430F5978EVM to help users evaluate the key features of RF430F5978 MCU, 3D LF wakeup and trigger function, passive (-free) transponder running and resonance micro-modulation panel devices. At the same time, EVM includes a USB insertion LF trigger module, RF430F5978 MCU evaluation board, AP434R01 access point, and 3D LF antenna. With this EVM, the designer can create the following demonstration: RF430F5978 MCU acquires data from multiple sensors within a period of time, once the reader's LF wake trigger is triggered, the RF430F5978 MCU will be transmitted through the RF link to Access point. Subsequently, these data are sent to the built-in host GUI to visualize the data curves and locations of the object. In addition, the EVM also accompanied by presentation code, an MSP430 code example, and a Code Composer Studiov.6 integrated development environment.
Characteristics and advantages of RF430F5978 MCU:
• The power consumption can be further reduced by allowing the RF radio and fast start LF wake-up function, which significantly extends battery life and significantly increases the ability to turn off the radio and start on the LF trigger.
• The position and distance (within 5 cm) can be tracked by the RSSI (received signal strength indicator) through the 3D LF transponder in the radius (4m) of the reader LF trigger (within 5 cm).
• A AES security coprocessor that can be encrypted and applied to product authentication and security access control can protect sensitive data and prevent signal interference.
• Programmable MSP430 kernel provides ultra-low power flexible customization.
• Applicable to a wide partial frequency range (from 300MHz to 950 MHz) below 1 GHz.
• Capacity can be reduced by integrating several key functions into a unified MCU and reduce costs.
• Can be used with TPS62163 and TPS62082 power management IC, SimpleLinkTM Wi-Fi CC3100, and BQ24040 IC, etc., complement each other.
