USB-C is the next big thing in hardware interfacing. Intel’s
ThunderBolt 3 design ecosystem features USB-C ports and connectors capable of
transmitting data at up to 40 Gigabits per second (Gbits/s) while decreasing
power consumption by half. Cypress Semiconductor Corp. recently announced its own programmable,
two-port USB-C controller
compatible for use with the Thunderbolt 3

According to Cypress, the EZ-PD CCG5 is the first two-port USB-C controller
on the market that supports Thunderbolt 3 controllers. It boasts built-in
protection against shorts and electrostatic discharge while helping with
bill-of-materials (BOM) integration to simplify design and inventory. The
device also includes 128 KB of flash memory to support a fail-safe boot up and
firmware upgrades.

The EZ-PD CCG5 supports downstream, upstream,
and dual role ports and fully supports the Power Delivery 3.0 specification. Two
timers, counters, PWMs, and up to 28 GPIOs are also fully integrated. The
device also includes 20-V regulators, sideband and USB high-speed muxes,
high-voltage FET gate drivers, and hardware dedicated to protecting the system
from over-voltage, under-voltage, and over-current fault conditions to form a
one-chip solution for USB-C integrated platforms. 

“The combination of Thunderbolt 3 and USB-C allows a
notebook to drive multiple 4K displays while simultaneously charging the
notebook over the same port,” according to Ajay Srikrishna, vice president of
Cypress’ Wired Connectivity Business Unit. “As part of the Thunderbolt 3 design
ecosystem, our programmable, two-port EZ-PD CCG5 controller is helping to drive
the proliferation of USB-C in desktop and notebook PCs, docking stations and

The programmable capabilities offered by the EZ-PD CCG5
should not be overlooked. The
highly-integrated Arm Cortex-M0 based controller includes enough Flash
memory to hold two firmware images, supporting a fail-safe boot and update
process. This capability means that features can be easily modified in
the field to provide updates to evolving standards, bug fixes, efficiency
improvements, customization for key customers and a host of other possible new
feature additions. This can dramatically improve the lifetime of a product and
deliver increased value to the customer.
