CY7C63823-PXC

Controllers Overview

The CY7C63823-PXC is a USB peripheral controller from the enCoRe II series, designed for low-speed USB device applications. It integrates an M8C CPU with Harvard architecture operating up to 24 MHz and includes up to 8 Kbytes of Flash memory with EEPROM emulation alongside 256 bytes of RAM. The component features a crystalless oscillator supporting external clocks, two internal 3.3 V regulators, and an integrated USB transceiver. It supports one control endpoint and two data endpoints, complying with USB Specification Version 2.0 and HID Specification Version 1.1.

Controllers Feature Summary

• Integrated crystalless oscillator eliminates the need for external crystals or resonators
• Configurable I/O interface allows operation as PS/2 or USB without external switching components
• Includes dedicated 3.3 V regulator for USB PHY signaling and D- line pull-up
• Supports in-system reprogrammability for firmware updates

Controllers Applications

• Low-speed USB human interface devices
• PS/2 to USB converter implementations
• Embedded systems requiring integrated USB connectivity

Controllers Procurement Notes

Verify the specific suffix 'PXC' against official Infineon documentation to confirm package type and temperature range. Confirm current lifecycle status as obsolete parts may require alternative sourcing strategies. Ensure compatibility with required voltage levels and interface protocols before procurement.

Controllers Selection Notes

Select this component for designs requiring a compact solution for low-speed USB peripherals. Consider the integrated regulators and crystalless design to reduce external component count. Verify that the 24 MHz CPU speed and memory sizes meet application requirements.

Controllers Part Context

This part belongs to the enCoRe II family, which focuses on reducing component count through high integration. It serves as a bridge between standard USB hosts and simple peripheral devices, offering a cost-effective alternative to discrete controller and transceiver combinations.

Controllers Replacement Considerations

As the part status is listed as obsolete, verify if newer revisions within the same family or updated pin-compatible controllers are available. Check for functional equivalence regarding endpoint support and GPIO configurations when evaluating substitutes.
