CY7C63823-SXC

Controllers Overview

The Infineon CY7C63823-SXC is an M8B enCoRe USB microcontroller designed for USB peripheral applications. It integrates 8 kilobytes of One-Time Programmable (OTP) memory and 256 bytes of RAM within a single integrated circuit. The device supports both USB and PS/2 interfaces, enabling versatile connectivity options for host and peripheral systems. It operates on a supply voltage range of 4.0 V to 5.5 V and functions reliably across a commercial temperature range of 0°C to +70°C. The component is housed in a compact 18-pin Small Outline Integrated Circuit (SOIC) package with a width of 7.50 mm, facilitating surface-mount assembly.

• Embedded USB connectivity modules

Controllers Procurement Notes

Verify the obsolete status of this component before initiating procurement processes. Confirm availability through authorized distributors or secondary market suppliers, as original manufacturer production has ceased. Ensure that any sourced units match the exact suffix specifications to guarantee pinout and functional compatibility with existing design requirements.

Controllers Selection Notes

Select this component when designing systems requiring combined USB and PS/2 interface support within a constrained footprint. Consider the 18-pin SOIC package dimensions for PCB layout constraints. Evaluate the 4V to 5.5V operating voltage range against system power rails. Note that the OTP memory requires specific programming infrastructure during the manufacturing phase.

Controllers Part Context

This part belongs to the Infineon enCoRe family of USB microcontrollers, which are optimized for low-cost, high-volume USB peripheral applications. The CY7C63823 variant specifically targets devices needing dual-interface support. It shares architectural similarities with other members of the CY7C637xx series but offers distinct memory configurations and interface combinations tailored for specific embedded control needs.

Controllers Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided documentation. Due to the discontinued status, engineers must evaluate alternative microcontrollers with comparable M8B architecture or verify cross-compatibility with newer enCoRe revisions through official Infineon engineering channels.
