OM6228

Introduction

The OM6228 is a member of the low-cost, high-performance family of intelligent 2.4 GHz RF transceivers with embedded microcontrollers. The OM6228 is optimized to provide a single chip solution for Ultra Low Power (ULP) wireless applications. The combination of processing power, memory, low power oscillators, real-time counter and a range of power saving modes provides an ideal platform for implementation of RF protocols. Benefits of using OM6228 include tighter protocol timing, security, lower power consumption and improved co-existence performance.
