Keyless entry reference design runs on Microchip mcus
Semtech and Microchip Technology have unveiled a reference design that is said to provide a turnkey platform for secure, low power multiband wireless remote keyless entry (RKE) systems. The design integrates Semtech's transmitter and transceiver ics with Microchip's KEELOQ code hopping technology running on PIC microcontrollers.
The reference design includes transmitter and receiver boards running KEELOQ encryption software and Microchip mcus. The Tx board pairs Semtech's SX1230 industrial, scientific and medical (ISM) band transmitter with Microchip's PIC16F631 or PIC16F677 8bit mcus. The Rx board employs Semtech's SX1211 or SX1212 ISM transceivers, again with Microchip's PIC16F631 or PIC16F677 mcus.
"Our relationship with Microchip means we can now provide a secure, turnkey RKE reference solution integrating the industry's highest performing microcontrollers and rf ics, along with leading security encryption software," said Sameer Vuyyuru, vp of marketing for Semtech's advanced communications and sensing group. "RKE designers now have a reference solution that does not require specialised rf design or encryption programming skills."
