CY8C21123-24SXIT

Overview

The CY8C21123-24SXIT is an 8-bit PSoC microcontroller featuring the M8C processor with speeds up to 24 MHz. It includes 4 KB of Flash program storage and 256 bytes of SRAM data storage. The device operates within a voltage range of 2.4 V to 5.25 V and supports an industrial temperature range from –40 °C to +85 °C. It integrates four analog Type E PSoC blocks for comparators and ADCs, along with four digital PSoC blocks for configurable peripherals.

Feature Summary

• Configurable analog and digital system-on-chip architecture allowing custom peripheral creation
• On-chip switch mode pump enabling operation from a single 1.2 V battery cell
• Flexible memory protection modes with in-system serial programming capability
• Programmable pin configurations with multiple drive modes on all GPIOs

Applications

• Battery-powered devices requiring low power consumption
• Industrial control systems operating in extreme temperatures
• Sensor nodes utilizing configurable analog inputs
• Embedded applications needing flexible I/O and communication interfaces

Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the SOIC-8 package. Confirm that the development environment supports the M8C core instruction set. Check for any end-of-life notifications or alternative component recommendations from the manufacturer.

Selection Notes

Select this component when a compact 8-bit solution with programmable analog capabilities is required. The integrated switch mode pump makes it suitable for single-cell battery applications. Consider the limited number of GPIO pins compared to larger packages in the same family. Evaluate the need for specific analog resolutions provided by the Type E blocks.

Part Context

This part belongs to the CY8C21x23 series of PSoC Programmable System-on-Chips. It shares architectural similarities with the CY8C21223 and CY8C21323, differing primarily in package options and pin counts. The series is designed to replace multiple traditional MCU components with a single programmable chip.

Replacement Considerations

Direct substitutes include other members of the CY8C21x23 family such as the CY8C21223 or CY8C21323, depending on package requirements. Verify pin compatibility and memory sizes before substitution.
