The PaLFI device combines a low frequency wireless interface with an SPI interface which ensures ultra-stable communication within a very well defined activation/communication zone. Upcoming product class releases include derivatives with security/authentication features and cost optimized versions with smaller memory minus the battery charge function for applications such as end of line product configuration.
Key features and benefits of the PaLFI
· Battery check and charge function via RF field supports operation of hermetically sealed devices such as implants.
· PaLFI memory is accessible via an SPI and wireless LF 134kHz interface allowing for access to additional microcontroller memory.
· The device can supply a battery powered MSP430 MCU with energy and operate the microcontroller even if the battery is empty ensuring data is still available and not getting lost.
· Low Frequency band (LF) ensures stable communication within a well defined reading zone.
· No battery required for data programming into the memory to allow an MCU to read content and use it for configuration, or calibration purposes once connected to the battery.
