Description
The SE2432L is a high performance, fully integrated RF Front-End
Module (FEM) designed for ZigBee®/Smart Energy applications.
The SE2432L is designed for ease of use and maximum flexibility.
The device provides integrated and fully matched input baluns, an
integrated inter-stage matching and harmonic filter, and digital
controls compatible with 1.6 to 3.6 V CMOS levels.
The RF blocks operate over a wide supply voltage range from
2.0 V to 3.6 V that allows the SE2432L to be used in battery
powered applications over a wide spectrum of the battery
discharge curve.
The SE2432L is provided in a small, 24-pin, 3 x 4 mm Quad Flat
No-Lead (QFN) package. The pin configuration and package are
shown in Figure 1. A functional block diagram is shown in
Figure 2. Signal pin assignments and functional pin descriptions
are provided in Table 1.

Note 1:
Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
Note 2:
Vcc2 is restricted to +3.6 V when operated at T

CAUTION:
Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
