CY7C65642-28 in USB 3.0 peripheral/controller ICs Family
The CY7C65642-28 family by Infineon Technologies (formerly Cypress Semiconductor) represents a highly integrated series of USB 2.0 hub controllers specifically optimized for low-power and space-constrained applications. Utilizing the TetraHub architecture, these controllers provide four downstream ports and provide independent power management for each. They are primarily designed to interface with various peripherals via I2C or SPI, serving as a reliable communication backbone for high-speed data transfers in industrial and consumer electronics environments.
Variants in This Sub-Family
Variants within the CY7C65642-28 sub-family primarily differ based on their thermal ratings and packaging options. Some models are optimized for commercial temperature ranges (0C to 70C), while industrial-grade versions accommodate more extreme environments. Additionally, variations in the shipping medium, such as tray versus tape-and-reel, distinguish specific part numbers like the CY7C65642-28LTXC, though the core silicon functionality and internal 8051 configuration remain consistent across the sub-series.
