AnSem developed an ASIC that integrates a 40kHz UltraSonic receiver for room detection together with an RFID transceiver for room access and wandering prevention. An integrated 640 kHz PLL serves as a clock for the companion RF chip. The ASIC communicates through an SPI interface with this RF chip.
First a concept phase was executed together with Televic. As a wireless communication specialist, AnSem assisted Televic in determining the right wireless technology for the room detection and room access. A bulky Proof of Concept with all features was built that allowed to test the system concept in real life circumstances.
In a next stage , the ASIC development was performed by AnSem. Custom ASICs have the benefit that they can achieve a small form factor, low power consumption and the target product cost.
AnSem provides a full turnkey solution: Beyond the design, it also supplies the ASIC in high volume and supports Televic throughout the complete Product Life Cycle.
“AnSem assisted us in transforming our innovation idea from hardware prototype to ASIC. By joining the ASIC expertise of AnSem and the healthcare product knowledge of Televic, we were able to have a first-time-right ASIC design” - John Gesquiere, R&D Director
