CC1101 Pinout

Package: 20-pin QFN (0.4 mm pitch)

Notes

• Exposed die attach pad: Must be connected to solid ground plane (main ground connection for the chip).
• DCOUPL pin: Output only; intended for CC1101 decoupling only—cannot supply other devices.
• Multiple AVDD pins (9, 11, 14, 15): All must be connected to 1.8–3.6 V analog supply.
• SPI interface: SCLK (1), SI (20), SO (2), CSn (7).
• General-purpose outputs: GDO0 (6), GDO1/SO (2), GDO2 (3) can be configured for various functions.

TA = 25 C if nothing else stated.

Table 17: DC Characteristics

Under no circumstances must the absolute maximum ratings given in Table 1 be violated. Stress exceeding one or more of the limiting values may cause permanent damage to the device.

Only a few external components are required for using the CC1101 . The recommended application circuits for CC1101 are shown in Figure 10 and

Figure 11. The external components are described in Table 20, and typical values are given in Table 21.

The 315 MHz and 433 MHz CC1101EM reference design [1] use inexpensive multilayer inductors. The 868 MHz and 915 MHz CC1101EM reference design [2] use wire-
