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”. No. Parameters Test Conditions Pin(1) Symbol Min. Typ. Max. Unit Type* *) 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. |
