CY8C26443-24SI Descripción general
What is a PSoC microcontroller? A PSoC is a programmable system-on-chip, a type of microcontroller that integrates a CPU with configurable analog and digital blocks. Unlike a general-purpose microcontroller that relies mainly on separate external peripherals, a PSoC can place sensing, conversion, control, and communication functions close to the processor on the same integrated circuit. The M8C PSoC 1 family is designed for embedded control applications where mixed-signal integration can reduce board complexity and support compact designs.
The CY8C26443-24SI's principal verified specifications are its 24 MHz operating speed, 8-bit processing class, and 16KB flash memory. The 28-SOIC package provides a surface-mount form factor for PCB assembly. The device is identified by the distributor as part of the Infineon Technologies CY8C26xxx family, while the original product documentation is also associated with Cypress Semiconductor. Its architecture and package make it relevant to designs requiring a compact embedded controller rather than a high-compute general-purpose MCU.
A PSoC's configurable mixed-signal resources can simplify designs that need analog-to-digital conversion, digital control, timers, communication, or other embedded functions. However, the supplied web data does not state the exact peripheral configuration, RAM capacity, voltage limits, temperature range, or package pin assignments. Those details must be confirmed against the manufacturer datasheet before final schematic capture or firmware configuration. The part number should therefore be treated as a family-specific selection, not as evidence of every possible PSoC block.
Typical applications include compact industrial controllers, consumer interfaces, sensor-conditioning systems, small motor and actuator controllers, and embedded products where an MCU and mixed-signal functions share a common package. The CY8C26443-24SI is most appropriate when a design requires the verified 24 MHz class, 16KB flash configuration, and 28-SOIC footprint. A final design must verify electrical limits, clocking, programming, and peripheral availability from the official technical documentation.
For layout and assembly, preserve the manufacturer-recommended decoupling and programming access requirements, and validate the exposed package dimensions and pin numbering against the selected package drawing. Because the verified data does not provide the official pinout, schematic implementation should use the datasheet and package drawing rather than inferred connections. This page distinguishes verified distributor facts from parameters requiring manufacturer documentation.

Aplicaciones típicas
CY8C26443-24SI es adecuado para 6 aplicacións: Compact Embedded Control, Sensor Interface Systems, Small Motor and Actuator Control, Consumer Interface Products, Industrial Module Control, Data Acquisition Front End.
Compact Embedded Control
The CY8C26443-24SI fits compact embedded-control products requiring an 8-bit controller, 24 MHz class operation, and 16KB of flash in a 28-SOIC package. A PSoC design can place control functions close to mixed-signal resources rather than relying only on a discrete CPU and separate peripheral devices. The verified data does not specify the exact RAM, timers, ADC, or I/O block, so firmware planning must first confirm the selected PSoC configuration. Its main design benefit is integration: fewer external functions may simplify the board, while the trade-off is that resource availability must be checked against the device's documented block configuration.
Recomendado
Sensor Interface Systems
The CY8C26443-24SI is relevant to small sensor-interface systems where an MCU must process digital control logic alongside sensing-related functions. Its PSoC architecture is intended to integrate configurable mixed-signal resources, which can reduce the distance between sensor conditioning and control logic. The verified listing confirms the 8-bit CPU class, 24 MHz speed, and 16KB flash, but it does not identify ADC resolution, sample rate, comparator resources, or sensor-specific peripherals. Those missing details are decisive for analog designs, so engineers must confirm the exact PSoC block diagram before selecting input ranges or designing signal-conditioning networks.
Recomendado
Small Motor and Actuator Control
The CY8C26443-24SI can be considered for compact actuator-control systems that need deterministic embedded logic in a surface-mount package. The 24 MHz operating class provides timing margin for state-machine control, while the 16KB flash capacity supports a modest control application. However, the supplied data does not confirm motor-driver outputs, PWM channels, capture/compare resources, or electrical limits. A practical design should therefore review the datasheet and verify whether the required actuator interface is internally available or must be implemented externally. The benefit is integration; the risk is selecting a device without the exact peripheral resources needed for motor control.
Recomendado
Consumer Interface Products
The CY8C26443-24SI is suitable for compact consumer interface products where an embedded controller must manage local buttons, indicators, or other low-bandwidth functions. Its 8-bit architecture, 24 MHz speed, and 16KB flash are appropriate as a starting point for a small control product, and the 28-SOIC package supports automated PCB assembly. The supplied evidence does not list GPIO count, communication peripherals, supply voltage, or package dimensions. Those omissions prevent a complete interface design from being released from search metadata alone. Confirm the electrical limits and available pins in the official documentation, then validate firmware size and startup behavior against the product requirements.
Recomendado
Industrial Module Control
The CY8C26443-24SI may fit an industrial control module that needs local logic and a compact, surface-mount MCU. The verified 28-SOIC package and 16KB flash support a small embedded design, while the 24 MHz class can handle straightforward control tasks and communications software. Industrial qualification, operating temperature, supply range, and isolation requirements are not stated in the provided data, so the part should not be treated as ruggedized or safety-certified by default. Use the exact datasheet limits and qualification markings before deployment. The PSoC integration may reduce board-level component count, but only after the required analog and digital blocks are confirmed.
Recomendado
Data Acquisition Front End
The CY8C26443-24SI is potentially relevant to a small data-acquisition front end because a PSoC can combine an embedded controller with configurable mixed-signal functions. The target's verified 24 MHz CPU class can support control sequencing around a sensing path, while 16KB flash limits the application to a suitably sized firmware image. The supplied data does not specify ADC count, resolution, sampling speed, input impedance, or analog voltage limits, which are essential for acquisition designs. Engineers should use the manufacturer documentation to verify signal-chain suitability and then determine whether external analog conditioning is required. The advantage is potential integration; the limitation is that no measured acquisition performance is provided here.

Notas de diseño
The verified package is 28-SOIC, but the supplied data does not include the official pinout, land pattern, or dimensions. Do not release a PCB footprint from the family name alone. Download the current Infineon/Cypress package drawing, verify pad numbering against every used signal, and confirm assembly tolerances with the board house before fabrication.
The supplied data confirms an internal oscillator and 24 MHz class operation but does not state supply voltage, current, or power limits. Confirm the operating range and decoupling requirements from the manufacturer datasheet, then size power capacity and trace widths for the actual peripheral configuration. A PSoC's enabled analog and digital blocks can change current consumption from the headline CPU specification.
Do not treat CY8C26443-24SXI, CY8C26443-24SXIT, or CY8C27443-24SI as confirmed drop-in replacements solely because search results identify related 28-SOIC parts. Compare the complete pin map, memory size, clock limits, peripherals, electrical characteristics, programming model, and qualification markings. Also distinguish Infineon listing records from original Cypress documentation when locating the controlling datasheet.
For any mixed-signal design, preserve the separation and grounding strategy recommended by the manufacturer datasheet. The supplied data does not specify ADC resolution, analog input range, converter speed, or reference behavior, so those parameters must be verified before choosing resistor dividers, filtering, or routing. Do not infer analog performance from the 24 MHz CPU frequency.
Información de cumplimiento
The supplied search data does not provide verified RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. Compliance must be confirmed from the current manufacturer product documentation and declaration.
