CY7C63723-PXC

Application Specific Microcontrollers Overview

The CY7C63723-PXC is an 8-bit RISC microcontroller from the enCoRe™ USB family, designed as a low-speed USB and PS/2 peripheral controller. It integrates an internal oscillator eliminating external crystals, 8 Kbytes of OTP EPROM, and 256 bytes of RAM. The device supports one USB device address with three data endpoints and auto-configures between USB and PS/2 modes without GPIO intervention. Key features include up to 16 configurable GPIO pins with 50 mA sink capability, SPI communication, capture timers, and operation within a 4.0V to 5.5V supply range at temperatures from 0°C to 70°C.

Application Specific Microcontrollers Feature Summary

• Integrated crystalless oscillator with auto-tuning for USB timing (6 MHz ±1.5%)
• Dual-mode interface supporting USB 2.0 and PS/2 HID specifications without external switching components
• 8-bit M8C CPU with 8 Kbytes OTP EPROM and 256 bytes RAM
• Up to 16 versatile GPIO pins with high current drive (50 mA sink) and maskable interrupts

Application Specific Microcontrollers Applications

• USB and PS/2 mice
• Gamepads and joysticks
• Wireless peripherals requiring RF input capture

Application Specific Microcontrollers Procurement Notes

Verify the -PXC suffix against official Infineon documentation to confirm package type and lead-free status. Confirm RoHS compliance and end-of-life status prior to procurement, as availability may be limited for legacy components.

Application Specific Microcontrollers Selection Notes

Select this component for applications requiring combined USB and PS/2 connectivity with minimal external bill of materials. Ensure firmware utilizes the internal oscillator precision tuning for USB compliance or configure an external 6-MHz ceramic resonator for higher stability.

Application Specific Microcontrollers Part Context

This part belongs to the Cypress Semiconductor CY7C637xx family, later acquired by Infineon Technologies. It shares architectural similarities with the CY7C63722 and CY7C63743, differing primarily in pin count and package options.

Application Specific Microcontrollers Replacement Considerations

Direct pin-compatible replacements are not publicly confirmed for the specific -PXC suffix. Evaluate CY7C63723 variants in different packages (e.g., SOIC, PDIP) if form factor changes are acceptable.
