ELECTRONICS/SENSORS: Melexis‘ MLX90109, its single chip, low-frequency (125 kHz) RFID transceiver, was selected by Somfy for use in a security application for homes and buildings. Originally designed for an automotive immobilizer application, the MLX90109 fits also industrial requirements in access control or pet identification. Although the big trend in contactless authentication is high-frequency RF communications (13.56 MHz), there are applications where low power, robustness and space constraints call for low-frequency contactless authentication. In all these cases, the MLX90109 is the key element for an optimum solution.
The MLX90109 was successfully designed-in at Somfy for its alarm control terminal. It is available in volume production together with an evaluation board and a development kit to speed up the development cycle of the customer. The transceiver chip is offered in a 0 to 70C version and a -40 to 85C version in the industry-standard SO8 pin package for surface mount manufacturing. Estimated pricing for the MLX90109 is 0.98 Euros at 50,000 pieces quantity.
