CY7C63723-SXC

Application Specific Microcontrollers Overview

The CY7C63723-SXC is an 8-bit RISC microcontroller from the enCoRe™ USB family, designed for low-speed USB and PS/2 peripheral applications. It features a crystalless internal oscillator eliminating external resonators, with CPU clock speeds up to 12 MHz. The device integrates 8 Kbytes of OTP EPROM and 256 bytes of RAM. Key peripherals include a USB serial interface engine supporting one device address and three endpoints, configurable GPIO ports with high current drive capabilities, SPI communication, capture timers, and watchdog reset logic. It operates within a voltage range of 4.0V to 5.5VDC and supports temperatures from 0°C to 70°C in an 18-pin SOIC package.

Application Specific Microcontrollers Feature Summary

• Integrated USB SIE supporting USB 2.0 and HID 1.1 specifications with one device address and three data endpoints
• Auto-configuring interface allowing seamless operation as either USB or PS/2 without external switching components
• Configurable GPIO ports with up to 50 mA sink current capability per pin

Application Specific Microcontrollers Applications

• USB and PS/2 mice
• Gamepads and joysticks
• Wireless RF input interfaces using capture timers

Application Specific Microcontrollers Procurement Notes

Verify component authenticity through authorized Infineon distributors or certified partners. Confirm RoHS compliance status and moisture sensitivity level (MSL) prior to assembly. Check for obsolescence notices or lifecycle changes, as this part number may be subject to discontinuation. Ensure proper handling procedures are followed due to humidity sensitivity.

Application Specific Microcontrollers Selection Notes

Select the CY7C63723-SXC when an 18-pin surface-mount solution is required for combined USB and PS/2 functionality. Choose this model over the CY7C63743 if fewer GPIO pins are sufficient, as it offers a smaller footprint. Consider the external oscillator option if higher precision timing is needed beyond the internal oscillator's capabilities.

Application Specific Microcontrollers Part Context

This component belongs to the Cypress Semiconductor (now Infineon) enCoRe™ USB family, specifically the CY7C637xx series. These microcontrollers are optimized for embedded USB and PS/2 applications, providing a cost-effective solution by integrating necessary USB transceivers and regulators on-chip. The 'SXC' suffix typically denotes the 18-pin SOIC package variant.

Application Specific Microcontrollers Replacement Considerations

Direct replacements within the same package and pinout include the CY7C63723-PC (PDIP version) or CY7C63743 variants if more I/O is needed. Verify firmware compatibility and electrical characteristics before substituting.
