CYPD2121-24LQXI

Overview

The CYPD2121-24LQXI is a USB Type-C port controller belonging to the EZ-PD™ CCG2 series, manufactured by Infineon Technologies (formerly Cypress Semiconductor). It integrates a 32-bit ARM Cortex-M0 processor running at 48 MHz with 32 KB of flash memory and 4 KB of SRAM. The device includes an integrated Type-C transceiver with baseband PHY, supporting USB Power Delivery protocols. Key electrical parameters include operation from 2.7 V to 5.5 V on VDDD, with independent I/O supply ranging from 1.71 V to 5.5 V. It features integrated termination resistors (RD, RA) and current sources (RP) for role detection.

Feature Summary

• Integrates a 48-MHz ARM Cortex-M0 CPU with 32-KB Flash and 4-KB SRAM.
• Includes an integrated USB Type-C transceiver with baseband PHY and BMC encoding/decoding.
• Features integrated RD, RA, and RP components for UFP, EMCA, and DFP identification.
• Supports industrial temperature range (-40 °C to +85 °C) in a 24-pin QFN package.

Applications

• USB Type-C EMCA cables
• USB Type-C powered accessories
• USB Type-C upstream facing ports (UFP)
• USB Type-C downstream facing ports (DFP)

Procurement Notes

The CYPD2121-24LQXI is listed as an End-of-Life (EOL) product by Infineon Technologies. Verification of availability should be conducted through authorized distributors or secondary market suppliers, as standard manufacturing supply has ceased. Designers should review the EOL notification documents for transition timelines.

Selection Notes

Select this component for single-port USB Type-C applications requiring programmable control via an embedded MCU. Ensure the design accommodates the 24-QFN package dimensions (4.0 mm x 4.0 mm). Verify that the host system supports the required communication interfaces (I2C, SPI, UART) provided by the Serial Communication Blocks (SCB).

Part Context

This part belongs to the EZ-PD™ CCG2 family, which utilizes Cypress’s proprietary M0S8 technology. The family includes variants like CYPD2120 and CYPD2122, differing primarily in package options and specific pin configurations while sharing the same core MCU and USB-PD subsystem architecture.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, alternative solutions from the EZ-PD CCGx portfolio (e.g., CCG3PA, CCG4, CCG5) should be evaluated based on pin compatibility and feature requirements.
