Serial 400 kHz I
data between the PCF50603 and the host controller
On/Off Control (OOC) module to control the power
ramp-up and ramp-down sequences for the handset.
Furthermore it determines the supported system
operating states: NOPOWER, SAVE, STANDBY and
ACTIVE to realize minimum power consumption in all
states.
Internal Current Controlled Oscillator (CCO) generates
the internal high clock frequency. The generated
frequency is typically 3.6 MHz.
An accurate 32.768 kHz oscillator. This oscillator can be
used to supply the 32 kHz clock domains in the system,
to improve the accuracy of the internal clock and to
reduce the power consumption of the PCF50603.
Interrupt controller (INT) that generates the interrupt
request for the host controller. All interrupt sources can
be masked.
The Real Time Clock (RTC) module uses the 32 kHz
clock to provide time reference and alarm functions with
wake up control for the handset
One accessory recognition pin with debounce filters and
capability to start up the system (REC1_N)
One accessory detection comparator input pin with
programmable threshold levels that issues an interrupt
when an accessory is connected (REC2_N)
Two Pulse-Width Modulators (PWM1 and PWM2) which
generate an output voltage with programmable duty
cycle and frequency
Two LED modulators (LED1 and LED2) capable of
generating eight different blinking patterns with eight
different repetition periods
Three General Purpose Outputs (GPO) programmable
via the serial interface. The GPOs are open-drain
NMOST outputs, capable of handling the full battery
voltage range and high sink currents. The GPOs can be
programmed to be continuously active LOW or 3-state,
in addition the GPO outputs can be controlled by the
LED or PWM modulators.
Watchdog timer that can be activated by software.

The power supplies have three programmable activity
modes (OFF, ECO and ON). In the ACTIVE state, the
operation modes can be selected by the two external
pins PWREN1 and PWREN2.
One Charge Pump (CP) with programmable output
voltage for the supply of white or blue LEDs
Two 100 mA LDO voltage regulators (RF1REG and
RF2REG) with fixed output voltage (mask
programmable) for RF supplies. RF1REG and RF2REG
are optimized for low noise, high power supply rejection
and excellent load regulation.
Two 150 mA LDO voltage regulators (D1REG and
D2REG) optimized for small external capacitors.
D1REG provides a programmable output voltage,
D2REG provides a fixed output voltage (mask
programmable).
One 150 mA LDO voltage regulator (IOREG) dedicated
for the supply of the I/O pads. IOREG has a fixed output
voltage (mask programmable) and is optimized for a
small external capacitor.
One 100 mA LDO voltage regulator (LPREG) with fixed
output voltage (mask programmable). In low power
operation (ECO) mode LPREG can be used to
permanently supply parts in the system in all activity
states.
One 100 mA LDO voltage regulator (D3REG) with
programmable output voltage. D3REG is optimized for a
small external capacitor.
One 250 mA LDO voltage regulator (HCREG) with
programmable output voltage. The high current HCREG
is optimized for applications like hands-free audio.
D1REG, D2REG, D3REG, IOREG and LPREG support
ECO mode. In this mode the output current is limited to
1 mA and the internal power consumption is reduced
significantly.
The Temperature high Sensor (TS) provides thermal
protection for the whole chip
Enhanced ESD protection on all pins that connect to the
main battery pack
Microphone bias voltage generator with low noise and
high power supply rejection (MBGEN).
