CY8C24994-24BVXI

Overview

The CY8C24994-24BVXI is a PSoC Programmable System-on-Chip featuring an M8C processor operating at 24 MHz. It includes 16 KB of flash program storage, 1 KB of SRAM, and supports in-system serial programming. The device integrates four digital PSoC blocks for configurable peripherals like timers and UARTs, and six analog PSoC blocks supporting up to 14-bit ADCs and 9-bit DACs. It features full-speed USB 2.0 compliance with a dedicated 256-byte buffer, requiring no external crystal. Operating voltage ranges from 3 V to 5.25 V within industrial temperature limits.

Feature Summary

• Configurable analog and digital logic blocks allow custom peripheral creation without fixed controller constraints.
• Full-speed USB interface enables communication without external crystals or complex components.
• Capacitive sensing application capability integrated into the analog system for touch sensing designs.
• Flexible GPIO configurations support various drive modes and interrupt capabilities across all pins.

Applications

• Capacitive touch sensing controllers
• USB-enabled data acquisition systems
• Industrial control interfaces with analog signal conditioning
• Portable battery-powered devices requiring low power operation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range. Ensure compatibility with legacy Cypress development tools if migrating existing projects. Confirm that the XRES pin functionality aligns with your reset requirements, as this feature is specific to certain variants within the CY8C24x94 family.

Selection Notes

Select this component when designing systems requiring both high-speed USB connectivity and flexible analog signal processing on a single chip. The combination of programmable analog blocks and digital logic reduces bill-of-materials count by replacing discrete components. Consider the 24 MHz processing speed and memory size relative to firmware complexity before finalizing the design choice.

Part Context

This part belongs to the CY8C24x94 series of PSoC devices, which are designed to replace multiple traditional MCU-based system components. The series offers varying amounts of digital and analog resources, with the CY8C24994 providing a balanced mix of 16 KB flash and extensive analog/digital configurability suitable for mid-range embedded applications.

Replacement Considerations

Direct substitutes include other members of the CY8C24x94 family such as the CY8C24894, noting differences in XRES pin availability. Cross-family migration to PSoC 4 or PSoC 5 requires significant architectural redesign due to differing core processors and peripheral structures.
