CYPD2125-24LQXI

Application Specific Microcontrollers Overview

The CYPD2125-24LQXI is a USB Type-C port controller from the EZ-PD™ CCG2 series, manufactured by Infineon Technologies (formerly Cypress Semiconductor). It integrates a 48-MHz ARM Cortex-M0 processor with 32 KB flash and 4 KB SRAM. The device includes an integrated Type-C transceiver with baseband PHY, supporting SOP, SOP', and SOP'' messaging. Key electrical parameters include a VDDD supply range of 2.7 V to 5.5 V and VDDIO signaling from 1.71 V to 5.5 V. It features two independent VCONN rails (4.0 V to 5.5 V) and supports industrial temperature ranges (-40 °C to +85 °C).
