Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

UCS1002 AND PIC16F1503
REFERENCE DESIGN
Chapter 1. Product Overview
1.1
INTRODUCTION
This UCS1002 and PIC16F1503 Reference Design is a fully functional universal serial
bus (USB) charger compatible with a large variety of portable devices.
The UCS1002 programmable port-power controller can deliver up to 2.5A charging
current. Features like current monitoring and programmable charger emulation profiles
make it a good candidate to be used with a PIC® Microcontroller for intelligent USB
charging solutions.
The algorithm implemented in the PIC microcontroller applies multiple charger
emulation profiles and selects the one that provides the highest current to the attached
device. For more information regarding the code, refer to AN1827 – "UCS1002 Highest
Current Algorithm Using a PIC® Microcontroller” (DS20001827A).
The board can be powered from 5V directly or through the MCP16323 Synchronous
Buck Regulator that allows 6-18V input.

Product Overview
1.3
GETTING STARTED
Depending on the available DC supply, the board has a variety of powering options.
One of the following options can be used:
• External power supply 6-18V DC on J6 jack connector. J11 must be unpopulated.
• External power supply 5V DC on J9, J1 or J7. J11 must be unpopulated.
• If the USB host can supply enough current for charging, then the external power
supply is not required and J11 must be populated.
J2 jumper must be populated to provide power to the corresponding USB connector
(J4). A current probe or a multimeter can be connected to J2 header for monitoring the
charging current and the voltage close to the USB connector.
After the proper jumper configurations are set and power is turned on, the portable
device to be charged can be plugged into the USB connector J4. The green LED (LD1)
turns on, confirming the attach detection.
The board comes with the PIC16F1503 microcontroller programmed with a firmware
version that communicates with only one of the two UCS1002 devices on the board (U1
on the schematic, with the corresponding USB connector J4). The other path available
on the board (containing the components U4, J8 and J10) can be enabled by changing
the I2C™ address of the UCS1002 in the firmware and reprogramming the MCU via the
J5 ICSP connector.

POWER SUPPLY
The board can be powered directly from a 5V DC supply or via the MCP16323
High-Efficiency Synchronous Buck Regulator, allowing input voltages from 6V to 18V
DC and output currents up to 3A at 5V.
Note:
Because of the space constraints, the power dissipation is limited, and the
maximum output current is lower than 3A.
The UCS1002 and PIC16F1503 Reference Design is designed with a split 5V supply:
• VS is input for the Power Switch of the UCS1002 device
• VDD is the main power supply to the PIC MCU and to UCS1002 (chip functionality)
The board comes with the R2, R29 and R30 (all with 0Ω values) populated, so VDD and
VS traces for the two UCS1002 are connected.
2.3
PIC16F1503 DEBUG SUPPORT (OPTIONAL)
The PIC16F1503 has no built-in debug circuitry. It requires the AC244051 external
header for debug support.
In order to use the in-circuit debug feature provided by the external header, these steps
must be followed:
1. Remove the PIC16F1503 from the board.
2. Populate the 14-pin DIP socket on the board (J12). The DIP socket is not
included in the UCS1002 and PIC16F1503 Reference Design kit.
3. Connect the external debug header to the DIP socket through the gold pins
headers provided in the AC244051 kit.
For more information on AC244051 debug header, refer to the latest “Processor
Extension Pack and Header Specification” (DS51292) document.

2.4
UCS1002 PIN CONFIGURATION
The UCS1002 device is configured to work in SMBus mode, with maximum hardware
current limit setting (2500 mA). The proper value pull-down resistor connected to
COMM_SEL/ILIM pin can be drawn from Section 4.1 - “Operating Mode” in the
UCS1002 data sheet. In this case, the value is 33 kΩ
PWR_EN polarity is set to active high and the SMBus addresses for the two UCS1002
devices on the board are the following (refer to Table 4.2 - “SEL Pin Decode” in the data
sheet):
• U1 - Address 33h: pull-down resistor value of 47 kΩ
• U4 - Address 30h: pull-down resistor value of 82 kΩ
The addresses specified above represent the hexadecimal value of the seven bits
shown in the table (without the RD/WR indicator bit).
The UCS1002 device is configured in Dedicated Charger Emulation by setting the
following logic states on M1, M2 and EM_EN pins (see Table 9.1 - “Active Mode
Selection” in the data sheet):
M1
M2
EM_EN
Active Mode
0
0
1
Dedicated Charger Emulation Cycle
The PWR_EN pin that controls the port power switch in Active state is set to a
logic-high state (active). When the board is powered up, the microcontroller sets the
PIN_IGNORE configuration bit in the UCS1002. This determines the PWR_EN to be
controlled by the microcontroller via SMBus communication. As a result, the status of
the PWR_EN pin is ignored by the UCS1002 device.
