Section 3 Specifications 3.1 Electrical Characteristics 3.1.1 Absolute Maximum Ratings Table 3-1. Absolute Maximum Ratings(1)(2) Parameters Min Max Voltage on any pin, except RESET with respect to Ground -0.5V VCC + 0.5V DC Current per I/O Pin 40 mA DC Current DVCC and DGND pins 300 mA Input RF Level +5 dBm Notes: 1. Absolute Maximum Ratings are the values beyond which damage to the device may occur. Under no circumstances must the absolute maximum ratings given in this table be violated.
Specifications Current consumption actually depends on multiple factors, including but not limited to, the board design and materials, BitCloud settings, network activity, EEPROM read/write operations. It also depends on MCU load and/or peripherals used by an application. 3.1.3 RF Characteristics Table 3-3. RF Characteristics Parameters Condition Frequency Band Unit 2.4000 to 2.

Specifications 9. Using ferrite bead and 1 µF capacitor located closely to the power supply pin is recommended, as shown below. 10. Pins 48, 49 and 50 are featured for ATZB-A24-U0 module only. 11. In SPI mode, USART0_EXTCLK is output. In USART mode, this pin can be configured as either input or output pin. ZigBit™ 2.
Specifications 3.4 Mounting Information The below diagrams show the PCB layout recommended for ZigBit Amp module. Neither via-holes nor wires are allowed on the PCB upper layer in area occupied by the module. As a critical requirement, RF_GND pins should be grounded via several holes to be located right next to pins thus minimizing inductance and preventing both mismatch and losses. Figure 3-4. 3.
Specifications 3.6 Antenna Reference Design Multiple factors affect proper antenna match, hence, affecting the antenna pattern. The particular factors are the board material and thickness, shields, the material used for enclosure, the board neighborhood, and other components adjacent to antenna. General Recommendations: Metal enclosure should not be used. Using low profile enclosure might also affect antenna tuning. Placing high profile components next to antenna should be avoided.
