RF Electrical Characteristics
Table 6 contains the digital I/O specifications for the EM250. The digital I/O power (named VDD_PADS) comes
from three dedicated pins (Pins 17, 23, and 28). The voltage applied to these pins sets the I/O voltage.

Table 7 lists the key parameters of the integrated IEEE 802.15.4 receiver on the EM250.
Note: Receive Measurements were collected with Ember’s EM250 Lattice Balun Reference Design (Version
Note: The adjacent channel rejection (ACR) measurements were performed by using an unfiltered, ideal

B1) at 2440MHz and using the EmberZNet software stack Version 3.0.1. The Typical number indicates
one standard deviation above the mean, measured at room temperature (25°C). The Min and Max
numbers were measured over process corners at room temperature.
