CY8C24123A4-24SXI

Overview

The Infineon CY8C24123A-24SXI is an 8-bit microcontroller based on the PSoC architecture, housed in an 8-pin SOIC package. It features an M8C processor core operating at a maximum clock frequency of 24 MHz. The device includes 4 KB of Flash program memory and 256 bytes of SRAM data storage. Key peripherals include six analog PSoC blocks supporting up to 14-bit ADCs and 9-bit DACs, four digital PSoC blocks for timers, counters, PWMs, UART, SPI, and I2C interfaces. It operates within a voltage range of 2.4 V to 5.25 V and supports an industrial temperature range of -40 °C to +85 °C.

Procurement Notes

Verify the exact ordering suffix against the manufacturer's current datasheet to ensure correct package type and temperature grade. Confirm RoHS compliance status as specifications may vary by production batch. Check for any specific errata or silicon revisions that might impact design integration. Ensure development tools such as PSoC Designer are compatible with the selected device variant before procurement.

Selection Notes

Select this component when a flexible mixed-signal solution is required to replace multiple discrete components. Consider the CY8C24123A-24SXI for designs needing configurable analog blocks alongside standard digital interfaces. Evaluate the available GPIO count and memory size against application requirements. Ensure the 8-pin package constraints meet the board layout needs while providing sufficient pin functionality for the intended system.

Part Context

This part belongs to the Cypress/Infineon PSoC 1 family, specifically the CY8C24x23A series. These devices are designed to integrate programmable analog and digital blocks with an 8-bit CPU. The family targets applications requiring high flexibility in peripheral configuration, reducing bill-of-materials count and board space compared to traditional fixed-function microcontrollers.

Replacement Considerations

Check for direct substitutes within the CY8C24x23A family, such as CY8C24223A or CY8C24423A, which share similar architectures but may differ in analog block counts or I/O configurations. Verify pin compatibility and software compatibility if migrating between variants.
