CY7C65216-24LTXI

Controllers Overview

The CY7C65216-24LTXI is a USB-I2C single-channel bridge controller compliant with USB 2.0 Full-Speed (12 Mbps) specifications. It features an integrated I2C interface supporting master and slave modes up to 400 kHz, equipped with 256-byte transmit and receive buffers. The device includes eight configurable GPIO pins and 512 bytes of internal flash memory for storing configuration parameters such as VID, PID, and descriptors. Operating voltage ranges from 1.71 V to 5.5 V, with industrial temperature support from -40 °C to 85 °C. It incorporates a 48-MHz clock oscillator, battery charger detection (BCD), and ESD protection rated at 2.2 kV HBM.

Controllers Feature Summary

• Integrates a fully configurable I2C serial communication block with dual 256-byte FIFO buffers.
• Includes internal 48-MHz and 32-kHz oscillators eliminating the need for external clock components.
• Supports USB Battery Charging Specification Rev 1.2 for peripheral detection of SDP, CDP, and DCP ports.
• Features 512-byte non-volatile flash memory for persistent storage of USB and I2C configuration parameters.

Controllers Applications

• Medical and healthcare devices requiring USB connectivity
• Point-of-Sale (POS) terminals
• Test and measurement systems
• Gaming systems and set-top boxes

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure package and tape-and-reel specifications match the design requirements. Confirm RoHS compliance status and moisture sensitivity levels prior to procurement. Cross-reference the part number with official Infineon distributors to validate availability and authenticity.

Controllers Selection Notes

Select this component when a dedicated USB-to-I2C bridge is required without firmware development. Ensure the application utilizes I2C protocols rather than UART or SPI, as this model lacks those interfaces. Verify that the target system operates within the specified 1.71 V to 5.5 V supply range and requires no more than eight general-purpose I/O pins.

Controllers Part Context

This component belongs to the EZ-USB Serial Bridge Controller family developed by Cypress Semiconductor, now part of Infineon Technologies. It serves as a cost-effective solution for enabling USB connectivity in legacy peripherals. Unlike other family members such as the CY7C65211 or CY7C65213, this specific variant is optimized exclusively for I2C bridging applications.

Controllers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult official Infineon resources for potential pin-compatible alternatives or updated series replacements.
