PAC5210
Power Application Controller
1. GENERAL DESCRIPTION
The PAC5210 belongs to Active-Semi's broad portfolio of full-featured Power Application Controller TM (PAC)
products that are highly optimized for controlling and powering next generation smart energy appliances,
devices, and equipment. These application controllers integrate a 50MHz ARM ® CortexTM-M0 32-bit
microcontroller core with Active-Semi's proprietary and patent-pending Multi-Mode Power Manager TM,
Configurable Analog Front EndTM, and Application Specific Power Drivers TM to form the most compact
microcontroller-based power and general purpose application systems ranging from digital power supply to
motor control. The PAC5210 microcontroller features up to 32kB of embedded FLASH and 8kB of SRAM
memory, a high-speed 10-bit 1µs analog-to-digital converter (ADC) with dual auto-sampling sequencers,
5V/3.3V I/Os, flexible clock sources, timers, a versatile 14-channel PWM engine, and several serial interfaces.
The Multi-Mode Power Manager (MMPM) provides “all-in-one” efficient power management solution for multiple
types of power sources. It features a configurable multi-mode switching supply controller capable of operating in
buck, flyback, or boost mode, and up to four linear regulated voltage supplies. The Application Specific Power
Drivers (ASPD) is medium voltage level open drain driver for general purpose driving. The Configurable Analog
Front End (CAFE) comprises differential programmable gain amplifiers, single-ended programmable gain
amplifiers, comparators, digital-to-analog converters, and I/Os for programmable and inter-connectible signal
sampling, feedback amplification, and sensor monitoring of multiple analog input signals. Together, these
modules and microcontroller enable a wide range of compact applications with highly integrated power
management, driving, feedback, and control for DC supply up to 52V and for line AC supply.

10.3. Functional Description
The Multi-Mode Power Manager (Figure 10-1) is optimized to efficiently provide "all-in-one" power management
required by the PAC and associated application circuitry from a wide range of input power sources. It
incorporates a dedicated multi-mode switching supply (MMSS) controller operable as a buck, flyback, or boost
converter to efficiently convert power from a DC or AC input source to generate a main supply output V P. Four
linear regulators provide VSYS, VCCIO, VCC33, and VCC18 supplies for 5V system, 5V or 3.3V I/O, 3.3V mixed signal,
and 1.8V microcontroller core circuitry. The power manager also handles system functions including internal
reference generation, timers, hibernate mode management, and power and temperature monitoring.
10.3.1. Multi-Mode Switching Supply (MMSS) Controller
The MMSS controller drives an external power transistor for pulse-width modulation switching of an inductor or
transformer for power conversion. The DRM output drives the gate of the n-channel MOSFET or the base of the
NPN between the VHM on state and VSSP off state at proper duty cycle and switching frequency to ensure that the
main supply voltage VP is regulated. The VP regulation voltage is initially set to 9V during start up, and can be
- 21 -
Rev 1.6‒April 15, 2016
PAC5210
Power Application Controller
reconfigured to be 5V, 12V, or 15V by the microcontroller after initialization. When V P is lower than the target
regulation voltage, the internal feedback control circuitry causes the inductor current to increase to raise V P.
Conversely, when VP is higher than the regulation voltage, the feedback loop control causes the inductor current
to decrease to lower VP. The feedback loop is internally stabilized. The output current capability of the switching
supply is determined by the external current sense resistor. In the high-side current sense buck mode, the
inductor current signal is sensed differentially between the CSM pin and V P, and has a peak current limit
threshold of 0.26V. In the low-side current sense flyback or boost mode, the inductor current signal is sensed
differentially between the CSM pin and VSSP, and has a peak current limit threshold of 1V.
The MMSS controller is flexible and configurable as a buck, flyback, or boost converter. Input sources include
battery supply for buck mode (Figure 10-2), and AC line supply voltage range for ultra-high-voltage buck mode
(Figure 10-3), AC/DC flyback mode(Figure10-4). The MMSS controller operational mode is determined by
external configuration and register setting from the microcontroller after power up. It can operate in either highside or low-side current sense mode, and does not require external feedback loop compensation circuitry. For
optional extended application range, the MMSS also incorporates additional digital control by the microcontroller
to add accurate computations for outer feedback loop control such as power factor correction and accurate
current control.

The MMSS detects and selects between high-side and low-side mode during start up based on the placement of
the current sense resistor and the CSM pin voltage. It employs a safe start up mode with a 9.5kHz switching
frequency until VP exceeds 4.3V under-voltage-lockout threshold, then transitions to the 45kHz default switching
frequency for at least 6ms to bring V P close to the target voltage, before enabling the linear regulators. Any extra
load should only be applied after the supplies are available and the microprocessor has initialized. The switching
frequency can be reconfigured by the microprocessor to be 181kHz to 500kHz in the high switching frequency
mode for battery-based applications, and to be 45kHz to 125kHz in the low switching frequency mode for AC
applications. Upon initialization, the microcontroller must reconfigure the MMSS to the desired settings for
VP regulation voltage, switching mode, switching frequency, and V HM clamp. Refer to the PAC application notes
and user guide for MMSS controller design and programming.
If a stable external 4.5V to 18V power source is available, it can power the V P main supply and all the linear
regulators directly without requiring the MMSS controller to operate. In such applications, V HM can be connected
directly to VP and the microcontroller should disable the MMSS upon initialization to reduce power loss.
10.3.2. Linear Regulators
The MMPM includes up to four linear regulators. The system supply regulator is a medium voltage regulator that
takes the VP supply and sources up to 200mA at REGO until V SYS, externally coupled to REGO, reaches 5V. This
allows a properly rated external resistor to be connected from REGO to V SYS to close the current loop and
offload power dissipation between V P and VSYS. Once VSYS is above 4V, the three additional 40mA linear
regulators for VCCIO, VCC33, and VCC18 supplies sequentially power up. Figure 10-5 shows typical circuit
connections for the linear regulators. For 5V I/O systems, short the V CCIO pin to VSYS to bypass the VCCIO
regulator. For 3.3V I/O systems, the V CCIO regulator generates 3.3V. The V CC33 and VCC18 regulators generate
3.3V and 1.8V, respectively. When V SYS, VCCIO, VCC33, and VCC18 are all above their respective power good
thresholds, and the configurable power on reset duration has expired, the microcontroller is initialized.

10.3.3. Power Up Sequence
The MMPM follows a typical power up sequence as in the Figure 10-6 below. A typical sequence begins with
input power supply being applied, followed by the safe start up and start up durations to bring the switching
supply output VP to 9V, before the linear regulators are enabled. When all the supplies are ready, the internal
clocks become available, and the microcontroller starts executing from the program memory. During
initialization, the microcontroller can reconfigure the switching supply to a different V P regulation voltage such as
15V and to an appropriate switching frequency and switching mode. The total loading on the switching supply
must be kept below 25% of the maximum output current until after the reconfiguration of the switching supply is
complete. For AC input supply applications, the start up sequence includes an additional charging time for V HM
depending on the start-up resistor and capacitor values.

10.3.4. Hibernate Mode
The IC can go into an ultra-low power hibernate mode via the microcontroller firmware or via the optional push
button (PBTN, see Push Button description in Configurable Analog Front End). In hibernate mode, only a
minimal amount (typically 18µA) of current is used by VHM, and the MMSS controller and all internal regulators
- 24 -

Power Application Controller
are shut down to eliminate power drain from the output supplies. The system exits hibernate mode after a wakeup timer duration (configurable from 125ms to 8s or infinite) has expired or, if push button enabled, after an
additional push button event has been detected. When exiting the hibernate mode, the power manager goes
through the start up cycle and the microcontroller is reinitialized. Only the persistent power manager status bits
(resets and faults) are retained during hibernation.
10.3.5. Power and Temperature Monitor
Whenever any of the VSYS, VCCIO, VCC33, or VCC18 power supplies falls below their respective power good threshold
voltage, a fault event is detected and the microcontroller is reset. The microcontroller stays in the reset state
until VSYS, VCCIO, VCC33, and VCC18 supply rails are all good again and the reset time has expired. A microcontroller
reset can also be initiated by a maskable temperature fault event that occurs when the IC temperature reaches
170°C. The fault status bits are persistent during reset, and can be read by the microcontroller upon reinitialization to determine the cause of previous reset.
A power monitoring signal V MON is provided onto the ADC pre-multiplexer for monitoring various internal power
supplies. VMON can be set to be VCC18, 0.4•VCC33, 0.4•VCCIO, 0.4•VSYS, 0.1•VREGO, 0.1•VP, 0.0333•VHM, or the internal
compensation voltage VCOMP for switching supply power monitoring.
For power and temperature warning, a V P low event at 77% of the regulation voltage and an IC temperature
warning event at 140°C are provided as maskable interrupts to the microcontroller. These warnings allow the
microcontroller to safely power down the system.
In addition to the temperature warning interrupt and fault reset, a temperature monitor signal VTEMP = 1.5 +
5.04e-3 • (T - 25°C) (V) is provided onto the ADC pre-multiplexer for IC temperature measurement.
10.3.6. Voltage Reference
The reference block includes a 2.5V high precision reference voltage that provides the 2.5V reference voltage
for the ADC, the DACs, and the 4-level programmable threshold voltage V THREF (0.1V, 0.2V, 0.5V, and 1.25V).

11.2. Functional Description
The device includes a Configurable Analog Front End (CAFE, Figure 11-1) accessible through up to 10 analog
and I/O pins. These pins can be configured to form flexible interconnected circuitry made up of up to 3
differential programmable gain amplifiers, 4 single-ended programmable gain amplifiers, 4 general purpose
comparators, 3 phase comparators, 10 protection comparators, and one buffer output. These pins can also be
programmed as analog feed-through pins, or as analog front end I/O pins that can function as digital inputs or
digital open-drain outputs. The PAC proprietary configurable analog signal matrix (CASM) and configurable
digital signal matrix (CDSM) allow real time asynchronous analog and digital signals to be routed in flexible
circuit connections for different applications. A push button function is provided for optional push button on,
hibernate, and off power management function.
11.2.1. Differential Programmable Gain Amplifier (DA)
The DAxP and DAxN pin pair are positive and negative inputs, respectively, to a differential programmable gain
amplifier. The differential gain can be programmable to be 1x, 2x, 4x, 8x, 16x, 32x, and 48x for zero ohm signal
source impedance. The differential programmable gain amplifier has -0.3V to 3.5V input common mode range,
and its output can be configured for routing directly to the ADC pre-multiplexer, or through a sample-and-hold
circuit synchronized with the ADC auto-sampling mechanism. Each differential amplifier is accompanied by
offset calibration circuitry, and two protection comparators for protection event monitoring. The programmable
gain differential amplifier is optimized for use with signal source impedance lower than 500Ω and with matched
source impedance on both positive and negative inputs for minimal offset. The effective gain is scaled by
13.5k / (13.5k + RSOURCE), where RSOURCE is the matched source impedance of each input.
11.2.2. Single-Ended Programmable Gain Amplifier (AMP)
Each AMPx input goes to a single-ended programmable gain amplifier with signal relative to V SSA. The amplifier
gain can be programmed to be 1x, 2x, 4x, 8x, 16x, 32x, and 48x, or as analog feed-through. The programmable
gain amplifier output is routed via a multiplexer to the configurable analog signal matrix CASM.
11.2.3. General Purpose Comparator (CMP)
The general purpose comparator takes the CMPx input and compares it to either the programmable threshold
voltage (VTHREF) or a signal from the configurable analog signal matrix CASM. The comparator has 0V to V SYS
input common mode range, and its polarity-selectable output is routed via a multiplexer to either a data input bit
or the configurable digital signal matrix CDSM. Each general purpose comparator has two mask bits to prevent
or allow rising or falling edge of its output to trigger second microcontroller interrupt INT2.
11.2.4. Phase Comparator (PHC)
The phase comparator takes the PHCx input and compares it to either the programmable threshold voltage
(VTHREF) or a signal from the configurable analog signal matrix CASM. The comparison signal can be set to a
phase reference signal generated by averaging the PHCx input voltages. In a three-phase motor control
application, the phase reference signal acts as a virtual center tap for BEMF detection. The PHCx inputs are
optionally fed through to the CASM. The phase comparator has 0V to V SYS input common mode range, and its
polarity-selectable output is routed to a data input bit and to the phase/position multiplexer synchronized with the
auto-sampling sequencers.
11.2.5. Protection Comparator (PCMP)
Two protection comparators are provided in association with each differential programmable gain amplifier, with
outputs available to trigger protection events and accessible as read-back output bits. The high-speed protection
(HP) comparator compares the PCMPx pin to the 8-bit HP DAC output voltage, with full scale voltage of 2.5V.
The limit protection (LP) comparator compares the differential programmable gain amplifier output to the 10-bit
LP DAC output voltage, with full scale voltage of 2.5V.
Each protection comparator has a mask bit to prevent or allow it to trigger the main microcontroller interrupt
INT1. Each protection comparator also has one mask bit to prevent or allow it to activate protection event PR1,
- 31 -
Rev 1.6‒April 15, 2016
PAC5210
Power Application Controller
and another mask bit to prevent or allow it to activate protection event PR2. These two protection events can be
used directly by protection circuitry in the Application Specific Power Drivers (ASPD) to protect devices being
driven.
11.2.6. Analog Output Buffer (BUF)
A subset of the signals from the configurable analog signal matrix CASM can be multiplexed to the BUF6 pin for
external use. The buffer offset voltage can be minimized with the built-in swap function.
11.2.7. Analog Front End I/O (AIO)
Up to 10 AIOx pins are available in the device. In the analog front end I/O mode, the pin can be configured to be
a digital input or digital open-drain output. The AIOx input or output signal can be set to a data input or output
register bit, or multiplexed to one of the signals in the configurable digital signal matrix CDSM. The signal can be
set to active high (default) or active low, with V SYS supply rail. Where AIO6,7,8,9 supports microcontroller interrupt
for external signals. Each has two mask bits to prevent or allow rising or falling edge of its corresponding digital
input to trigger second microcontroller interrupt INT2.
11.2.8. Push Button (PBTN)
The push button PBTN, when enabled, can be used by the microcontroller to detect a user active-low push
button event and to put the system into an ultra-low-power hibernate mode. Once the system is in hibernate
mode, PBTN can be used to wake up the system. In addition, PBTN can also be used as a hardware reset for
the microcontroller when it is held low for longer than 8s during normal operation. The PBTN input is active low
and has a 55kΩ pull-up resistor to 3V.
11.2.9. HP DAC and LP DAC
The 8-bit HP DAC can be used as the comparison voltage for the high-speed protection (HP) comparators, or
routed for general purpose use via the AB2 signal in the CASM. The HP DAC output full scale voltage is 2.5V.
The 10-bit LP DAC can be used as the comparison voltage for the limit protection (LP) comparators, or routed
for general purpose use via the AB3 signal in the CASM. The LP DAC output full scale voltage is 2.5V.
11.2.10. ADC Pre-Multiplexer
The ADC pre-multiplexer is a 16-to-1 multiplexer that selects between the 3 differential programmable gain
amplifier outputs, AB1 through AB9, temperature monitor signal (V TEMP), power monitor signal (VMON), and offset
calibration reference (VREF / 2). The ADC pre-multiplexer can be directly controlled or automatically scanned by
the auto-sampling sequencer.
When the ADC pre-multiplexer is automatically scanned, the unbuffered or sensitive signals should be masked
by setting appropriate register bits.
11.2.11. Configurable Analog Signal Matrix (CASM)
The CASM has 9 general purpose analog signals labeled AB1 through AB9 that can be used for:
 Routing the single-ended programmable gain amplifier or analog feed-through output to AB1 through AB9
 Routing an analog signal via AB1, AB2, or AB3 to the negative input of a general purpose comparator or
phase comparator
 Routing the 8-bit HP DAC output to AB2
 Routing the 10-bit LP DAC output to AB3
 Routing analog signals via AB1 through AB12 to the ADC pre-multiplexer
 Routing phase comparator feed-through signals to AB7, AB8, and AB9, and averaged voltage to AB1
11.2.12. Configurable Digital Signal Matrix (CDSM)
The CDSM has 7 general purpose bi-directional digital signals labeled DB1 through DB7 that can be used for:

12.3.2. Power Drivers Control
All power drivers are initially disabled from power-on-reset. To enable the power drivers, the microprocessor
must first set the driver enable bit to '1'. The OMx open-drain drivers are controlled by their corresponding
register bits. Refer to the PAC application notes and user guide for additional information on power drivers
control programming.
12.3.3. Gate Driver Fault Protection
The ENHS1 (protection group 1 control output) and ENHS2 (protection group 2 control output) pins are provided
for enabling external power drivers with fault protection.

13.2. Functional Description
13.2.1. ADC
The analog-to-digital converter (ADC) is a 10-bit succesive approximation register (SAR) ADC with 1 μs
conversion time and up to 1MSPS capability. The ADC input clock has a user-configurable divider from /1 to /8
of the system clock. The integrated analog multiplexer allows selection from up to 6 direct ADx inputs, and from
up to 10 analog inputs signals in the Configurable Analog Front End (CAFE), including up to 3 differential input
pairs. The ADC can be configured for repeating or non-repeating conversions and can interrupt the
microcontroller when a conversion is finished.
13.2.2. Auto-Sampling Sequencer
Two independent and flexible auto-sampling sequencer state machines allow signal sampling using the ADC
without interaction from microcontroller core. Each auto-sampling sequencer state machine can be programmed
to take and store up to 8 samples each in the ADC result register from different analog inputs, able to control the
ADC MUX and ADC Premux as well as the precise timing of the S/H in the Configurable analog front end. The
sampling start of the auto-sampling sequencer can be precisely triggered using timers A, B, C, or D or any of
their associated PWM edges (high-to-low or low-to-high). It also supports manual start or a ping-pong-scheme,
where one auto-sampling sequencer state machine triggers the other when it finishes sampling.

Rev 1.6‒April 15, 2016
PAC5210
Power Application Controller
The auto-sampling sequencer can interrupt the microcontroller when either conversion sequence is finished.
13.2.3. EMUX Control
A dedicated low latency interface controllable by the auto-sampling sequencer or register control allows
changing the ADC premultiplexer and asserting/deasserting the S/H circuit in the configurable analog front end,
allowing back to back conversions of multiple analog inputs without microcontroller interaction.

15.3. Functional Description
The PAC clock control system covers a wide range of applications.
15.3.1. Free Running Clock (FRCLK)
The free running clock (FRCLK) is generated from one of the 4 clock sources: ring oscillator, trimmed RC
oscillator, crystal driver or external clock input. The FRCLK is used for the real-time clock (RTC), watchdog
timer (WDT), input to the PLL, or FCLK source to clock the system in low power and sleep mode.
15.3.2. Fast Clock (FCLK)
The fast clock (FCLK) is generated from the PLL or supplied by the FRCLK directly. The FCLK supplies the
watchdog timer (WDT), ADC, wake-up interrupt controller (WIC), SysTick timer, ARM Cortex-M0 peripheral high
speed clock (HCLK) and low speed clock (LSCLK).
15.3.3. High-Speed Clock (HCLK)
The high-speed clock (HCLK) is derived from the FCLK with a /1, /2, /4 or /8 divider. It supplies the peripheral
AHB/APB bus, Timers A to D, dead-time controllers, SPI interface, I 2C interface, UART interface, EMUX
interface, SOC bridge interface and memory subsystem, and can go as high as 50MHz.
15.3.4. Auxiliary Clock (ACLK)
The auxiliary clock (ACLK) is derived from FCLK with a /1, /2, to /128 divider, and supplies the timer and
dead-time blocks. It can be clocked faster or slower than HCLK and can go as high as 100MHz.
15.3.5. Clock Gating
The clock tree supports clock gating in deep-sleep mode for the timer block, ADC, SPI interface, I 2C interface,
UART interface, memory subsystem and the ARM Cortex-M0 itself.
15.3.6. Ring Oscillator (ROSC)
The integrated ring oscillator provides 4 different clocks with 7.5MHz, 9.6MHz, 13.8MHz, and 25.7MHz settings.
After reset, the clock tree always defaults to this clock input with the lowest frequency setting.
15.3.7. Trimmed 4MHz RC Oscillator
The 1% trimmed 4MHz RC oscillator provides an accurate clock suitable for many applications. It is also used to
derive the clock for the Multi-Mode Power Manager.
15.3.8. Internal Slow RC Oscillator
An internal 32kHz RC oscillator is used during start up to provide an initial clock to analog circuitry. It is not used
as a clock input to the clock tree.
15.3.9. Crystal Oscillator Driver
The optional crystal oscillator driver can drive crystals from 2MHz to 10MHz to provide a highly accurate and
stable clock into the system.
15.3.10. External Clock Input
The clock tree can be supplied with an external clock up to 10MHz.
15.3.11. PLL
The integrated PLL input clock is supplied by the FRCLK with an input frequency range of 1MHz to 25MHz. The
PLL output frequency is adjustable from 3.5MHz to 100MHz.

The microcontroller nested vectored interrupt controller (NVIC) supports 25 external interrupts for the device's
peripherals and sub-systems. For low-latency interrupt processing, the NVIC also supports interrupt tailchaining. The wake-up interrupt controller (WIC) is able to wake up the device from low-power modes using any
GPIO interrupt, as well as from the RTC or WDT. The ARM Cortex-M0 supports both sleep and deep-sleep lowpower modes. The deep-sleep mode supports clock gating to limit standby power even further.
Firmware debug support includes 4 break-point and 2 watch-point unit comparators using the serial wire debug
(SWD) protocol. The serial wire debug mechanism can be disabled to prevent device access to the firmware in
the field.

19.2. Functional Description
The device includes 9 timers: timer A, timer B, timer C, timer D, watchdog timer 1 (WDT), watchdog timer 2,
wake-up timer, real-time clock (RTC), and SysTick timer. The device supports up to 14 different PWM signals
and has up to 7 dead-time controllers. Timers A, B, C and D can be concatenated to synchronize to a single
clock and start/stop signal for applications that require a synchronized timer period between timers.
19.2.1. Timer A
Timer A is a general purpose 16-bit timer with 8 PWM/capture and compare units. It has 4 pairs of PWM signals
going into 4 dead-time controllers. Timer A can be concatenated with timers B, C, and D to synchronize the
PWM/capture and compare units. It can use either ACLK or HCLK as clock input with an additional clock divider
from /1 to /128.
19.2.2. Timer B
Timer B is a general purpose 16-bit timer with 2 PWM/capture and compare units. It has one pair of PWM
signals going into one dead-time controller, as well as 2 additional compare units that can be used for additional
system time bases for interrupts. Timer B can be concatenated with timers A, C, and D to synchronize the
PWM/capture and compare units. It can use either ACLK or HCLK as clock input with an additional clock divider
from /1 to /128.
19.2.3. Timer C
Timer C is a general purpose 16-bit timer with 2 PWM/capture and compare units. It has one pair of PWM
signals going into one dead-time controller. Timer C can be concatenated with timers A, B, and D to synchronize
the PWM/capture and compare units. It can use either ACLK or HCLK as clock input with an additional clock
divider from /1 to /128.

19.2.4. Timer D
Timer D is a general purpose 16-bit timer with 2 PWM/capture and compare units. It has one pair of PWM
signals going into one dead-time controller. Timer D can be concatenated with timers A, B, and C to synchronize
the PWM/capture and compare units. It can use either ACLK or HCLK as clock input with an additional clock
divider from /1 to /128.
19.2.5. Watchdog Timer
The 24-bit watchdog timer (WDT) can be used for long time period measurements or periodic wake up from
sleep mode. The watchdog timer can be used as a system watchdog, or as an interval timer, or both. The
watchdog timer can use either FRCLK or FCLK as clock input with an additional clock divider from /2 to /65536.
19.2.6. SOC Bus Watchdog Timer
The watchdog timer 2 is used to monitor internal SOC Bus communication. It will trigger device reset if there is
no SOC Bus communication to the AFE for 4s or 8s.
19.2.7. Wake-Up Timer
The wake-up timer can be used for very low power hibernate and sleep modes to wake up the micro controller
periodically. It can be configured to be 125ms, 250ms, 500ms, 1s, 2s, 4, or 8s.
19.2.8. Real-Time Clock
The 24-bit real-time clock (RTC) can be used for time measurements when an accurate clock source is used.
This timer can also be used for periodic wake up from sleep mode. The RTC uses FRCLK as clock input with an
additional clock divider from /2 to /65536.
