CY8C24423-24PI Overview
A PSoC mixed-signal microcontroller is a programmable system-on-chip that combines a microcontroller core with configurable analog and digital resources. In the product hierarchy, this device belongs to the MCU family, then to 8-bit microcontrollers, and finally to programmable mixed-signal controllers. The M8C core provides the digital control platform, while the PSoC architecture is designed for embedded products that need both control logic and signal conditioning or interface functions. This combination can reduce the need for separate peripheral devices when the application requirements are modest and firmware can configure the resources appropriately.
The most important verified characteristics are the 8-bit processing class, 4KB flash memory, M8C core, and 28-DIP package. The source search result describes the part as a PSoC Mixed Signal Array, indicating that its value is not limited to basic digital GPIO control. The package is suited to prototyping, through-hole assembly, educational platforms, and legacy or repair-oriented embedded systems where a DIP footprint simplifies manual insertion and socket-based assembly. Exact clock speed, RAM size, ADC specifications, GPIO count, voltage range, and operating-temperature limits are not present in the supplied data and must be confirmed from the manufacturer datasheet before design release.
Typical engineering use cases include small sensor-conditioning systems, simple control panels, keypad interfaces, low-speed communication modules, and educational embedded-control platforms. For a sensor interface, the MCU can execute acquisition-control logic and coordinate signal processing, although the supplied source does not verify a specific ADC resolution or sampling rate. For a control panel, the M8C core can manage discrete inputs and outputs, while the PSoC resources may reduce external circuitry when their electrical limits and configuration options are confirmed. Firmware compatibility, peripheral availability, and timing performance should be evaluated from the device documentation.
The main design consideration is package and sourcing risk. A 28-DIP footprint is mechanically convenient but is not interchangeable with a surface-mount package without a PCB redesign. Before substituting any part, verify every pin, supply voltage, clock configuration, memory map, programming method, and peripheral function. This page also synthesizes source identity, distributor inventory information, and engineering guidance that is not visible from the basic catalog description alone.

Typical Applications
CY8C24423-24PI is suitable for 6 applications: Simple Embedded Control Panel, Sensor Conditioning Controller, Educational Microcontroller Training Board, Legacy Through-Hole Instrument, Low-Speed Communication Interface, Small Motor or Relay Controller.
Simple Embedded Control Panel
The CY8C24423-24PI fits early embedded control-panel prototypes that use an 8-bit microcontroller to read discrete commands and drive indicator or actuator signals. Its verified 4KB flash provides a defined code-storage baseline, while the M8C core identifies the software platform. The 28-DIP package is convenient for hand assembly, sockets, and educational boards. Before final selection, verify GPIO count, debounce timing, output drive limits, supply voltage, and any required communication peripheral.
Recommended
Sensor Conditioning Controller
The CY8C24423-24PI can be evaluated for a small sensor-conditioning system because the source identifies it as a PSoC Mixed Signal Array rather than a basic digital-only controller. The M8C core can coordinate measurement control and decision logic, while the programmable mixed-signal resources may reduce external conditioning circuitry. The supplied evidence does not specify ADC resolution, sampling rate, input range, or analog timing, so these values must be confirmed from the manufacturer datasheet before selecting the MCU.
Recommended
Educational Microcontroller Training Board
The CY8C24423-24PI is well suited to an educational embedded-systems board because it combines a recognizable 8-bit M8C architecture with a through-hole 28-DIP package. Students can assemble the device without fine-pitch rework, access the package pins on a breadboard or socket, and experiment with firmware and mixed-signal control. The 4KB flash limit encourages compact code organization. Confirm programming connector details, clock components, and device documentation before publishing a reproducible lab design.
Recommended
Legacy Through-Hole Instrument
The 28-DIP package makes CY8C24423-24PI relevant to legacy instruments and repair platforms where through-hole replacement simplifies mechanical work. A socketed controller can be removed and replaced without exposing a compact board to repeated rework, while the 8-bit core is adequate for supervisory logic when the workload is limited. Before using it in a safety- or measurement-critical product, verify clock accuracy, ADC behavior, temperature range, electrical limits, and any required legacy firmware compatibility.
Recommended
Low-Speed Communication Interface
The CY8C24423-24PI may be used as the supervisory controller in a low-speed interface that coordinates status, configuration, or simple command handling. Its PSoC mixed-signal classification provides a path to configurable functions, but the available data does not identify UART, SPI, I2C, USB, or CAN resources. Verify the exact peripheral set and pin multiplexing in the manufacturer documentation. If the interface requires modern high-speed connectivity, choose a dedicated transceiver or a MCU with verified protocol support.
Recommended
Small Motor or Relay Controller
A CY8C24423-24PI-based controller can supervise low-power switching functions such as relays, indicators, or small actuators when the required timing and output current remain within the device's verified limits. The 8-bit core is suitable for deterministic supervisory logic, and the 28-DIP package supports through-hole prototypes. The supplied data does not verify output-driver current, isolation, switching frequency, or thermal limits, so use an appropriate driver stage and confirm all absolute maximum ratings before connecting loads.

Design Notes
Use the verified 28-DIP footprint and preserve the package's mechanical dimensions and pin numbering. Do not substitute a surface-mount part without redesigning the PCB. Before routing power and signals, confirm the complete manufacturer pinout because the supplied distributor description confirms the package count but does not identify individual pin functions.
The operating supply range and absolute maximum ratings are not present in the supplied verified data. Confirm the manufacturer limits before adding decoupling or connecting external circuitry. Select capacitors and protection components based on the actual supply voltage and switching requirements, and include a local bulk and bypass arrangement appropriate to the final power topology.
The 4KB flash figure is catalog-level information and should not be treated as a complete memory specification. Check RAM, bootloader behavior, programming requirements, and firmware size before committing to a design. A replacement is also unsafe if its firmware model, pin muxing, clock setup, or PSoC resource map differs even when the package name matches.
For analog or mixed-signal use, keep sensor inputs and sensitive signals away from switching nodes and high-current return paths. Establish a compact ground reference and follow the manufacturer layout guidance once the complete pinout and electrical limits are verified. Because the supplied data does not identify analog pin locations or impedance requirements, this note is general design guidance rather than a device-specific layout prescription.
Compliance Information
The supplied source snippets do not state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 status for CY8C24423-24PI. Confirm current declarations with Infineon or the authorized manufacturer documentation.
