1 Introduction
EZ-PD CCG3 belongs to
Cypress’s family of USB Type-C microcontrollers that complies with the latest USB Type-C
and Power Delivery (PD) standards. It consists of a dual bank of 64 KB of flash memory, 8 KB of SRAM memory, a
crypto engine for authentication, and a pair of VCONN field-effect transistors (FETs). In addition, with the integrated
Billboard controller, over-voltage protection (OVP), and over-current protection (OCP), it helps to reduce the need for
additional components and the overall cost of a Type-C ecosystem. Typical applications using CCG3 include power
adapters, power banks, Type-C dongles, notebooks, Thunderbolt hosts and cables, monitors, and docks.
