• Features six rail-to-rail analog PSoC blocks supporting ADCs up to 14-bit resolution, DACs, programmable gain amplifiers, and filters.
• Includes four digital PSoC blocks configurable as timers, counters, PWMs, UARTs, SPI masters/slaves, and CRC modules.
• Provides full-speed USB 2.0 connectivity (12 Mbps) with five endpoints and a 256-byte buffer, requiring no external crystal.

Applications

• Capacitive sensing applications using CSA capability
• Battery-powered systems utilizing internal voltage reference and low power modes
• USB-enabled peripheral devices requiring direct host communication
• Industrial control systems operating in wide temperature ranges

Procurement Notes

Verify the specific ordering suffix LTXIT corresponds to the QFN-56 package and reel packaging configuration. Confirm that the component meets RoHS compliance requirements for your target market. Ensure design compatibility with the specified 3 V to 5.25 V operating voltage range. Check for any silicon errata related to the CY8C24x94 family before finalizing production designs.

Selection Notes

Select this component when a design requires integrated analog and digital programmability alongside native USB connectivity. The CY8C24794 is suitable for applications needing flexible GPIO routing and mixed-signal processing without external discrete components. Consider the 16 KB Flash size for firmware complexity and the 1 KB SRAM for runtime data handling needs.
