8 / 44 page  www.national.com 8 Revision 1.0 6.0 Electrical Specifications 6.1 GENERAL SPECIFICATIONS Absolute Maximum Ratings (see Table 9) indicate limits beyond which damage to the device may occur. Operating Ratings (see Table 10) indicate conditions for which the device is intended to be functional. This device is a high performance RF integrated circuit and is ESD sensitive. Handling and assembly of this device should be performed at ESD free workstations. The following conditions apply unless otherwise stated in the tables below: • TA = -40°C to +85°C • VCC = 3.3V, IOVCC = 3.3V • RF system performance specifications are guaranteed on National Semiconductor Austin Board rev1.0b refer- ence design platform. Table 9. Absolute Maximum Ratings Symbol Parameter Min Max Unit VCC Core Logic Power Supply Voltage -0.3 4.0 V IOVCC I/O Power Supply Voltage -0.3 4.0 V USB_VCC1 USB Power Supply Voltage -0.5 3.63 V VI Voltage on any pad with GND = 0V -0.5 3.6 V PinRF RF Input Power +15 dBm TS Storage Temperature Range -65 +125 oC TL Lead Temperature (solder 4 sec) +235 oC ESD-HBM ESD, Human Body Model 2000 2 V ESD-MM ESD, Machine Model 200 V 1. USB Interface not supported by LMX9820A firmware. Treat as no connect. Pad required for mechanical stability. 2. Antenna pin passes 1500V HBM. Table 10.
