PIN CONFIGURATION

The UPD1002 32-SQFN package provides selectable pin configurations via the CFG_SEL0 and CFG_SEL1 pins, as

defined in Table 3-3, "32-SQFN CFG_SELx Configuration Assignments". Table 1-1, "UPD1002 Package/Pin Configura-

tion Summary" provides a summary of the available pin configurations . Refer to Section 2.1, "32-Pin SQFN (32-SQFN)"

for details on the package pin definitions.

3.3.3

RECEPTACLE TYPE

The USB receptacle type is configurable between Standard-A, Standard-B, and Micro-AB types via the CFG_SEL0 and

CFG_SEL1 pins, as defined in Section 3.3, "Configuration Selection (CFG_SEL0/CFG_SEL1)". Each of these recepta-

cle type settings is detailed below.

3.3.3.1

Standard-A (STD-A)

The Standard-A setting informs the device that the designer is utilizing a Standard-A USB PD receptacle.

3.3.3.2

Standard-B (STD-B)

The Standard-B setting informs the device that the designer is utilizing a Standard-B USB PD receptacle.

3.3.3.3

Micro-AB (uAB)

The Micro-AB setting informs the device that the designer is utilizing a Micro-AB USB PD receptacle.

3.3.4

USB POWER DELIVERY ROLE SELECTION

The Power Delivery Provider and Consumer capabilities are detailed in the following sub-sections. Depending on the

pin configuration selected, the device may support and swap Consumer and Provider roles. The swapping rules for each

configuration are defined as follows:

Note:

For summary of all device pinouts and their associated Power Delivery capabilities, refer to Table 1-1,

"UPD1002 Package/Pin Configuration Summary".

Downstream Facing Port (DFP) Provider Configurations (32-P_A)

DFP Provider (STD-A receptacle) configurations only support the Provider role and therefore do not support role swap.

Upstream Facing Port (UFP) Consumer/Provider Configurations (32-CP_B)

UFP Consumer/Provider (STD-B receptacle) configurations start operation in their default role of consumers and sup-

port role swapping. Swapping rules for UFP Consumer/Provider configurations are defined as follows:

• When operating as a Consumer:

- Upon starting up, the UFP automatically initiates a swap request to its partner to become a Provider. If the

partner rejects the request, the UFP will remain in its Consumer role until the partner requests a swap.

- If the device receives a swap request from its partner to become a Consumer, it automatically accepts it.
