Low Power Clock
For the Bluetooth low power clock, a 32.768-kHz crystal can be used to drive the SiW3500 oscillator circuit, or alterna-
tively, a 32.768-kHz reference clock signal can be used instead of a crystal. If the lowest power consumption is not
required during low-power modes such as sniff, hold, park, and idle modes, the 32.768-kHz crystal may be omitted in the
design. If the 32.768-kHz clock source is used, the clock source should be connected to the CLK32_IN pin via an AC-
coupling capacitor (100 pF or greater), and its amplitude must meet the following requirements:
For AC-coupled via 100 pF or greater (peak-to-peak voltage):
400 mVP-P < CLK32_IN < VDD_C
Note:
Note: It is recommended to keep CLK32_IN voltage to 1 Vp-p maximum to minimize the I/O power supply current when the
VBATT_ANA and VBATT_DIG are shut off while VDD_P and VDD_P_ALT are still powered. The CLK32_OUT can be left open.
However, connecting the CLK32_OUT pin to either VDD_P or GND through a 100 nF capacitor improves the circuit's sensitivity
slightly if operating near the low end of the CLK32_IN range above.
Power Supply Description
The SiW3500 operates at 1.8 V core voltage for internal analog and digital circuits. The chip has internal analog and
digital voltage regulators simplifying power supply requirements to the chip. The internal voltage regulators can be
supplied directly from a battery or from other system voltage sources. Optionally, the internal regulators can be by-
passed if a 1.8 V regulated source is available on the system.
Note:
Both regulators can be bypassed if external regulation is desired. When bypassing the analog regulator, the VBATT_ANA and
VCC_OUT pins must be tied together and the external analog voltage (1.8 V) should be applied to the VBATT_ANA pin. When
bypassing the digital regulator, the VBATT_DIG pin should be left unconnected and the external digital voltage (1.8 V) should be
applied to VDD_C pin.
The power for the I/Os is taken from two separate sources (VDD_P and VDD_P_ALT). They can range from 1.62 to 3.63
Volts to maintain compatibility with a wide range of peripheral devices. Please check the pin list for the exact pins that are
powered from the VDD_P and VDD_P_ALT sources.
RF I/O Description
The SiW3500 employs single-ended RF input and output pins for reduced external components. In typical power class 2
(0 dBm nominal) applications, no external matching components are necessary.
On-Chip Memory
The SiW3500 SoC integrates both SRAM and ROM. The ROM is pre-programmed with Bluetooth protocol stack
software (HCI software) and boot code that executes automatically upon reset. The boot code serves to control the boot
sequence as well as to direct the execution to the appropriate memory for continued operation.
