CY7C66113C-LTXC

Application Specific Microcontrollers Overview

The CY7C66113C-LTXC is a full-speed USB peripheral microcontroller with an integrated 4-port hub, manufactured by Infineon Technologies (formerly Cypress Semiconductor). It features an 8-bit Harvard architecture CPU running at a 12 MHz internal clock derived from a 6 MHz external source. The device includes 8 KB of one-time programmable memory and 256 bytes of RAM. Key hardware components include a 1:4 hub repeater, I2C master/slave controller, Hardware Assisted Parallel Interface (HAPI), and a Digital-to-Analog Converter (DAC) port with programmable current sinks. It operates within a voltage range of 4.0V to 5.5V DC.

Application Specific Microcontrollers Feature Summary

• Integrated Full-Speed USB Peripheral Controller and 4-Port Hub
• 8-Bit Microcontroller with 12 MHz Internal Clock and 8 KB PROM
• Digital-to-Analog Converter (DAC) Port with Programmable Current Sinks
• Hardware Assisted Parallel Interface (HAPI) and I2C Compatible Controller

Application Specific Microcontrollers Applications

• USB compound devices requiring integrated hub functionality
• Keyboard hubs and similar human interface devices
• Systems requiring programmable high-current outputs via DAC ports

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'LTXC' against official Infineon documentation to confirm temperature grade and packaging details, as datasheets primarily reference standard PVXC variants. Ensure compatibility with industry-standard programmers for OTP programming. Confirm RoHS compliance status for the specific manufacturing lot.

Application Specific Microcontrollers Selection Notes

Select this component for applications needing both USB host communication and downstream port expansion in a single chip. The CY7C66113C variant is required over the CY7C66013C if DAC functionality or additional GPIO pins are necessary. Ensure the design supports the 4.0V–5.5V operating voltage range and utilizes a 6 MHz crystal for proper clocking.

Application Specific Microcontrollers Part Context

This part belongs to the CY7C66x13C family, which combines a USB microcontroller with a hub. It is designed for compound devices where space and cost efficiency are critical. The device replaces separate microcontroller and hub ICs, simplifying board layout and reducing component count for USB-enabled peripherals.

Application Specific Microcontrollers Replacement Considerations

The CY7C66013C is a related pin-compatible variant lacking the DAC port. Verify if the DAC functionality is essential; if not, the CY7C66013C may serve as a substitute. No other direct cross-model replacements are documented in the provided source material.
