CY8C24223A-24PVXA

Overview

The CY8C24223A-24PVXA is an 8-bit microcontroller within the Infineon PSoC 1 family, featuring the M8C processor core. It integrates 4 KB of Flash program memory and 256 bytes of SRAM data storage. The device supports operating voltages from 2.4 V to 5.25 V and includes a switch-mode pump for operation down to 1.0 V. It offers up to 24 GPIOs with configurable drive modes. Analog capabilities include six PSoC blocks providing up to 14-bit ADCs and 9-bit DACs. Digital resources comprise four PSoC blocks supporting timers, counters, PWMs, UART, SPI, and I2C interfaces.

Feature Summary

• Configurable analog and digital PSoC blocks allow custom peripheral creation
• M8C Harvard-architecture processor with integrated multiply-accumulate unit
• Flexible GPIO configuration with multiple drive modes and interrupt capabilities
• Internal clocking system with precision oscillators and PLL support

Applications

• Consumer electronics requiring low power and mixed-signal processing
• Industrial control systems utilizing programmable analog front ends
• Communication devices implementing serial protocols like UART and SPI
• Battery-powered instruments leveraging the on-chip switch-mode pump

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range. Ensure compatibility with the PSoC Designer development environment. Confirm that the selected variant meets all electrical specifications for your target application voltage and frequency requirements before integration.

Selection Notes

Select this component when design flexibility for both analog and digital peripherals is required in a single chip. The CY8C24223A is suitable for applications needing precise analog signal conditioning alongside robust digital control logic. Consider the available GPIO count and memory size relative to system complexity. Evaluate the need for the switch-mode pump if ultra-low voltage operation is critical.

Part Context

This part belongs to the CY8C24x23A series of the PSoC 1 family, derived from the earlier CY8C24x23 devices. It represents a mixed-signal array solution designed to replace multiple discrete components. The architecture emphasizes programmability through configurable blocks rather than fixed-function peripherals, allowing significant reduction in board space and component count.

Replacement Considerations

Direct substitutes within the same family include the CY8C24123A and CY8C24423A, which share similar architectural features but may differ in pin counts or specific peripheral configurations. Verify pin compatibility and resource availability when migrating between these variants.
