CY7C63413-PVC

Application Specific Microcontrollers Overview

The CY7C63413-PVC is a low-speed, high I/O USB controller manufactured by Infineon Technologies (originally Cypress Semiconductor). It integrates an 8-bit RISC microcontroller with a 12 MHz internal CPU clock and an integrated USB Serial Interface Engine (SIE) compliant with USB Specification Version 1.0. The device features 8 Kbytes of EPROM, 256 bytes of RAM, and 32 General Purpose I/O pins capable of sinking up to 12 mA. It supports one device address and three data endpoints, operating within a voltage range of 4.0V to 5.5VDC at temperatures from 0°C to 70°C.

Application Specific Microcontrollers Feature Summary

• Integrated 8-bit RISC microcontroller with 12 MHz internal clock and 8 Kbytes of EPROM
• USB SIE compliant with USB 1.0 and HID 1.0 specifications, supporting 3 data endpoints
• 32 GPIO pins with configurable pull-ups and sink currents up to 12 mA per pin
• Includes 12-bit free-running timer, watchdog timer, and power-on reset logic

Application Specific Microcontrollers Applications

• Keyboards and keyboards with integrated pointing devices
• Gamepads and other human interface devices
• Low-speed USB applications requiring high I/O counts

Application Specific Microcontrollers Procurement Notes

Verify the manufacturer origin, as the component was originally produced by Cypress Semiconductor before its acquisition by Infineon Technologies. Confirm the package type corresponds to the 'PVC' suffix, which indicates a 40-pin PDIP configuration. Ensure firmware compatibility with the specific EPROM size and instruction set architecture defined in the datasheet.

Application Specific Microcontrollers Selection Notes

Select this model when 8 Kbytes of program memory is required for USB HID applications. Compare against CY7C63411 (4 KB EPROM) and CY7C63412 (6 KB EPROM) if code space is limited. Note that the CY7C635xx series offers additional DAC port capabilities not present in the CY7C634xx series.

Application Specific Microcontrollers Part Context

This component belongs to the CY7C634xx/635xx family of One Time Programmable (OTP) microcontrollers designed specifically for USB connectivity. The CY7C63413 variant provides the maximum EPROM capacity (8 Kbytes) within the standard GPIO-only subset of the family, distinguishing it from the CY7C635xx series which includes programmable current sink outputs.

Application Specific Microcontrollers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should verify pinout and electrical compatibility if considering alternative OTP USB controllers.
