3 Description
The FPC202 dual port controller serves as a lowspeed signal aggregator for common port types such
as SFP, QSFP, Mini-SAS HD, and others. The
FPC202 aggregates all low-speed control and I2C
signals across two ports and presents a single easyto-use management interface to the host (I2C or SPI).
Multiple FPC202s can be used in high-port-count
applications with one common control interface to the
host.

SNLS565 – DECEMBER 2017
5 Description Continued
The FPC202 is designed to allow placement on the bottom side of the PCB, underneath the press fit connector,
to simplify routing. This localized control of the ports’ low-speed signals cuts system bill of materials (BOM) cost
by enabling the use of smaller I/O count control devices (FPGAs, CPLDs, MCUs) and by reducing routing layer
congestion.
The FPC202 is compatible with standard SFF-8431, SFF-8436, and SFF-8449 low-speed management
interfaces, including a dedicated 100/400-kHz I2C interface to each port. Additional general-purpose pins are
available to perform functions such as driving port status LEDs or controlling power switches. The LED drivers
have convenience features such as programmable blinking and dimming. The interface to the host controller can
operate on a separate supply voltage between 1.8 V and 3.3 V to support low-voltage I/Os.
For each port, the FPC202 has a total of four LED drivers, 12 general-purpose I/Os, and two downstream I2C
busses. This expanded set of I/Os allows for control of additional components and features within a system. The
general-purpose outputs can be used to drive additional LEDs if more than four are required per port.
The FPC202 can pre-fetch data from user-specified registers in each module, making the data readily accessible
to the host through a fast I2C (up to 1 MHz) or SPI (up to 10 MHz) interface. In addition, the FPC202 can trigger
an interrupt to the host whenever critical, user-configurable events occur associated with any of the ports under
its control. This eliminates the need to continuously poll the modules.

7.5 Electrostatic Discharge Caution
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
