Triac Control/PWM
The CYBT-X430XX-01 includes hardware support for zero-crossing detection and trigger control for up to two triacs (PAD 22/23). The
CYBT-X430XX-01 detects zero-crossing on the AC zero detection line and uses that to provide a pulse that is offset from the zero
crossing. This allows the CYBT-X430XX-01 to be used in dimmer applications, as well as any other applications that require a control
signal that is offset from an input event.
The zero-crossing hardware includes an option to suppress glitches.
Serial Peripheral Interface
The CYBT-X430XX-01 has two independent SPI interfaces. One is a master-only interface (SPI2) and the other (SPI1) can be either
a master or a slave. Each interface has a 64-byte transmit buffer and a 64-byte receive buffer. To support more flexibility for user
applications, the CYBT-X430XX-01 has optional I/O ports that can be configured individually and separately for each functional pin.
The CYBT-X430XX-01 acts as an SPI master device that supports 1.8V or 3.3V SPI slaves. The CYBT-X430XX-01 can also act as
an SPI slave device that supports a 1.8V or 3.3V SPI master.
SPI voltage depends on VDD; therefore, it defines the type of devices that can be supported.
Power Management Unit
The Power Management Unit (PMU) provides power management features that can be invoked by software through power
management registers or packet-handling in the baseband core.
RF Power Management
The BBC generates power-down control signals for the transmit path, receive path, PLL, and power amplifier to the 2.4 GHz trans-
ceiver, which then processes the power-down functions accordingly.
