• Integrated full-speed USB 2.0 controller with dedicated internal SRAM for communication endpoints
• Supports multiple clock sources including internal main oscillator and external crystal inputs
• Includes programmable analog blocks such as ADC, comparators, and IDAC connected via analog mux

Applications

• USB-enabled embedded control systems
• Low-power portable devices requiring flexible I/O configuration
• Applications needing integrated analog signal processing capabilities

Procurement Notes

Verify the specific memory configuration (8 KB Flash/1 KB SRAM) matches the design requirements, as the CY8C24x93 family offers varying memory sizes. Confirm the QFN-48 package availability and ensure compliance with RoHS directives. Check for any silicon errata relevant to the specific revision before finalizing production integration.

Selection Notes

Select this component when a combination of USB connectivity and configurable analog/digital resources is required in a single chip. Consider the 1.71 V minimum supply voltage for battery-operated applications. Evaluate the available GPIO count against pinout constraints, noting that USB functionality may occupy specific pins on the QFN-48 package.

Part Context

This part belongs to the CY8C24x93 series of PSoC Programmable System-on-Chip devices. These devices are designed to replace multiple traditional MCU-based components by integrating configurable logic, analog functions, and communication interfaces onto a single die, simplifying manufacturing and reducing inventory costs.

Replacement Considerations

Consult the official datasheet for cross-reference information. Verify if alternative members of the CY8C24x93 family with different memory sizes or pin counts meet the functional requirements without necessitating hardware redesign.
