Hello,
I'm searching RF Chip/MCU for RF remote controller with below requirements.
1. Application: car audio with max 10keys + keyless entry as option
2. Requirements:
a. Operating voltage : 3.0V typ (use CR2025 battery)
b. Must withstand high temperature (90deg C for storage and 80deg C for operation).
c. Transmission distance minimum 10 meters, use 2.4GHz frequency band.
d. Because of small PCB space, need small footprint, less surround components,
prefer one chip/system-on-chip. (separated RF chip and MCU will required extra space.
e. Low cost... (very strict pricing)
Any recommendations?
It will be very helpful if you can provide reference circuit etc...
Thanks,
