INTRODUCTION

1.1

General Description

The UPD1001 is a USB Power Delivery (PD) controller designed to adhere to the USB Power Delivery Specification.
USB Power Delivery allows a host (or device) to provide or consume up to 5 Amps and/or up to 20 Volts of power from
a USB PD capable partner device on the other end of the USB cable. USB PD capable standard and custom cables/
connectors are supported, which in most cases are backward compatible with standard USB connections. 

The UPD1001 provides a complete USB Power Delivery solution for all charger and adapter solutions. The functionality
of the UPD1001 is selected via two configuration selection pins, CFG_SEL0 and CFG_SEL1, which can be used to
select unique PD and system configurations. Designing the UPD1001 into a system can be as simple as selecting a
configuration, with no external EEPROM required. Advanced programmability options exist with an external EEPROM
installed. 

The integrated USB Power Delivery MAC and PHY support provider and consumer operation via the PD communication
protocol, as specified in Revision 1.0 (Version 1.2) of the USB Power Delivery Specification. Monitoring of VBUS and
battery charging is accomplished via the integrated voltage and current ADC inputs. The PHY supports cable ID detec-
tion/identification and loopback modes. The PHY includes a 24MHz FSK modulator/demodulator and provides inte-
grated terminations. The USB PD MAC supports both USB PD insertion detection (cold socket) and dead battery cases. 

The on-chip microcontroller manages the IOs and implements the power delivery local policy engine and device man-
ager. The SPI ROM controller is used by the microcontroller for optional external code execution from ROM. A One Time
Programmable (OTP) ROM is integrated in the UPD1001. Integrated 3.3 V and 1.8 V regulators allow device operation
from a single power supply. The UPD1001 is available in commercial (0°C to +70°C) and industrial (-40°C to +85°C)
temperature ranges. An internal block diagram of the UPD1001 is shown in 

Figure 1-1

.

The UPD1001 is offered in a 32-pin SQFN package. The package provides multiple pin configurations, based upon the
CFG_SEL0 and CFG_SEL1 Configuration Select signals. 

Table 1-1

 summarizes the available pin combinations and

their target applications. Refer to 

Section 2.0, "Pin Descriptions and Configuration," on page 6

 for detailed information

on specific pin configurations.

select unique PD and system configurations. Designing the UPD1001 into a system can be as simple as selecting a
configuration, with no external EEPROM required. Advanced programmability options exist with an external EEPROM
installed. 

The integrated USB Power Delivery MAC and PHY support provider and consumer operation via the PD communication
protocol, as specified in Revision 1.0 (Version 1.2) of the USB Power Delivery Specification. Monitoring of VBUS and
battery charging is accomplished via the integrated voltage and current ADC inputs. The PHY supports cable ID detec-
tion/identification and loopback modes. The PHY includes a 24MHz FSK modulator/demodulator and provides inte-
grated terminations. The USB PD MAC supports both USB PD insertion detection (cold socket) and dead battery cases. 

The on-chip microcontroller manages the IOs and implements the power delivery local policy engine and device man-
ager. The SPI ROM controller is used by the microcontroller for optional external code execution from ROM. A One Time
Programmable (OTP) ROM is integrated in the UPD1001. Integrated 3.3 V and 1.8 V regulators allow device operation
from a single power supply. The UPD1001 is available in commercial (0°C to +70°C) and industrial (-40°C to +85°C)
temperature ranges. An internal block diagram of the UPD1001 is shown in

INTRODUCTION

1.1

General Description

The UPD1001 is a USB Power Delivery (PD) controller designed to adhere to the USB Power Delivery Specification.
USB Power Delivery allows a host (or device) to provide or consume up to 5 Amps and/or up to 20 Volts of power from
a USB PD capable partner device on the other end of the USB cable. USB PD capable standard and custom cables/
connectors are supported, which in most cases are backward compatible with standard USB connections. 

The UPD1001 provides a complete USB Power Delivery solution for all charger and adapter solutions. The functionality
of the UPD1001 is selected via two configuration selection pins, CFG_SEL0 and CFG_SEL1, which can be used to
select unique PD and system configurations. Designing the UPD1001 into a system can be as simple as selecting a
configuration, with no external EEPROM required. Advanced programmability options exist with an external EEPROM
installed. 

The integrated USB Power Delivery MAC and PHY support provider and consumer operation via the PD communication
protocol, as specified in Revision 1.0 (Version 1.2) of the USB Power Delivery Specification. Monitoring of VBUS and
battery charging is accomplished via the integrated voltage and current ADC inputs. The PHY supports cable ID detec-
tion/identification and loopback modes. The PHY includes a 24MHz FSK modulator/demodulator and provides inte-
grated terminations. The USB PD MAC supports both USB PD insertion detection (cold socket) and dead battery cases. 

The on-chip microcontroller manages the IOs and implements the power delivery local policy engine and device man-
ager. The SPI ROM controller is used by the microcontroller for optional external code execution from ROM. A One Time
Programmable (OTP) ROM is integrated in the UPD1001. Integrated 3.3 V and 1.8 V regulators allow device operation
from a single power supply. The UPD1001 is available in commercial (0°C to +70°C) and industrial (-40°C to +85°C)
temperature ranges. An internal block diagram of the UPD1001 is shown in 

Figure 1-1

.

The UPD1001 is offered in a 32-pin SQFN package. The package provides multiple pin configurations, based upon the
CFG_SEL0 and CFG_SEL1 Configuration Select signals. 

Table 1-1
