Question: What is Cypress’s portfolio to support RF remote design?
Answer: Cypress provides a portfolio of low cost, low power, and high performance solutions for RF remote controllers. The solutions provide simultaneous support for RF and legacy IR operations. The portfolio features low power (can support >100,000 button presses with single coin cell battery), reduced BOM, battery management support up to 30 meter range, and operation at angles up to 60 degrees. In addition, enCoRe MCUs feature an 8-bit RISC core with flash memory, low power, and a variety of internal peripheral functions.
There are two types of solutions available for RF remote control design:
- 2-chip solutions: separate MCU and RF ICs
- Single-chip solution: combing RF and MCU in a single chip
The following table lists Cypress’s RF remote control portfolio. Based on the required features of the solution, the relevant products can be chosen for the design.
