12. Electrical Characteristics: General (Continued)

This device is manufactured with an industrial (not automotive) grade process and process controls. Although this device may

meet certain automotive grade criteria in performance, Atmel can not recommend that this device be used in any automotive

application.

All parameters refer to GND and are valid for Tamb = 25°C, VVS1 = VVS2 = 3.0V (1-battery application), VVS2 = 6.0V (2-battery application)

and VVS2 = VVAUX = 5.0V (Base-station Application). Typical values are given at fRF = 433.92 MHz unless otherwise specified. Details

about current consumption, timing and digital pin properties can be found in the specific sections of the “Electrical Characteristics”.

*) Type means: A = 100% tested, B = 100% correlation tested, C = Characterized on samples, D = Design parameter

Note:

1. Pin numbers in brackets mean they were measured with RF_IN matched to 50

Ω according to Figure 3-1 on page 11 with

component values according to Table 3-2 on page 12 and RF_OUT matched to 50

Ω according to Figure 3-10 on page 21

with component values according to Table 3-7 on page 22.
