Overview

The MC33596 is a highly integrated receiver designed for low-voltage applications. It includes a programmable PLL for multi-channel applications, an RSSI circuit, a strobe oscillator that periodically wakes up the receiver while a data manager checks the content of incoming messages. A configuration switching feature allows automatic changing of the configuration between two programmable settings without the need of an MCU.
