CY7C65216D-32LTXI

Controllers Overview

The CY7C65216D-32LTXI is a USB Dual I2C Bridge Controller compliant with USB 2.0 Full-Speed (12 Mbps) specifications. It features two configurable I2C interfaces supporting master/slave modes up to 400 kHz, each equipped with 256-byte transmit and receive buffers. The device integrates Battery Charger Detection (BCD) compliant with USB BC 1.2 for peripheral detection. It includes an internal 48-MHz oscillator, 512 bytes of flash memory for configuration storage, and 12 general-purpose input/output pins. Operating voltages range from 1.71 V to 5.5 V, with commercial (0 °C to 70 °C) and industrial (-40 °C to 85 °C) temperature ratings.

Controllers Feature Summary

• Dual-channel I2C interface with independent 256-byte buffers per channel
• Integrated Battery Charger Detection compliant with USB BC 1.2 specification
• Internal 48-MHz clock oscillator eliminating external crystal requirements
• Configurable GPIOs supporting LED driving and power control functions

Controllers Applications

• Medical and healthcare devices
• Point-of-Sale terminals
• Test and measurement systems
• Gaming systems
• Set-top box PC-USB interfaces

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with required operating voltage ranges and temperature grades before procurement. Confirm driver availability for the target operating system environment.

Controllers Selection Notes

Select this component when dual isolated I2C buses are required over a single USB connection. Verify that the 400 kHz I2C speed meets system timing requirements. Check if the integrated BCD functionality aligns with charging port detection needs. Ensure the 12 GPIO count satisfies interface requirements without excessive pin multiplexing.

Controllers Part Context

This part belongs to the Cypress/Infineon USB Serial Bridge Controller family, specifically designed as a USB-I2C bridge. It serves as a firmware-free solution for adding USB connectivity to legacy peripherals requiring I2C communication. It replaces discrete USB-to-I2C converter chips in compact designs.

Controllers Replacement Considerations

Direct replacements within the same family include CY7C65216, which offers similar functionality but may differ in GPIO count or package options. Verify pinout compatibility and software driver support when substituting.
