CY8C24223-24SI 概要
A microcontroller is a programmable control IC that executes firmware, reads inputs, controls outputs, and manages system timing. The CY8C24223 belongs to the PSoC 1 family, where a mixed-signal array integrates digital control logic with programmable analog and digital peripheral blocks. This makes it useful when a design needs configurable sensing, control, timing, or interface behavior without using several separate ICs.
The verified distributor data identifies the device as an 8-bit microcontroller with 24 MHz operation, 4 KB flash organized as 4K x 8, 256 bytes of RAM, and switch-mode pump support. Its 20-SOIC package supports conventional surface-mount assembly. The supplied records do not provide the complete electrical limits, temperature range, converter or ADC specifications, pin names, package dimensions, or compliance declarations.
This device is appropriate for compact embedded controllers, keypad and user-interface products, simple sensor acquisition, actuator control, industrial modules, and low-cost consumer products. Firmware can use the integrated PSoC architecture to route signals and configure peripheral blocks, while the 24 MHz M8C core provides the execution basis for control logic. Exact peripheral assignment and performance must be confirmed against the manufacturer datasheet.
A key design consideration is resource planning: 4 KB of flash and 256 bytes of RAM constrain application size, so firmware should be sized before adding high-buffer protocols or complex algorithms. Board design should also preserve clean analog grounding and follow the manufacturer’s decoupling and pin-assignment guidance when configuring sensitive mixed-signal functions.
This product page combines verified distributor specifications, source traceability, application guidance, and explicit data gaps so engineers can evaluate CY8C24223-24SI without treating unverified technical values as specifications.

主な用途
CY8C24223-24SI の用途: 6 件s: Compact Embedded Control Module, Simple Sensor Acquisition, Keypad and User Interface Control, Actuator and Discrete Control, Low-Cost Consumer Interface, Portable Measurement Device.
Compact Embedded Control Module
The CY8C24223-24SI fits compact embedded controllers that execute 8-bit control logic at 24 MHz while using the PSoC mixed-signal architecture to combine digital processing with configurable analog and digital functions. Its 4 KB of flash and 256 bytes of RAM make it most appropriate for bounded control loops, status monitoring, and local configuration rather than large application stacks. Designers should budget flash and RAM before finalizing firmware, then use the manufacturer pin and peripheral assignment tables to configure the mixed-signal blocks. The verified record does not provide supply voltage or temperature limits, so those must be checked against the industrial or commercial requirements before release.
おすすめ
Simple Sensor Acquisition
The PSoC mixed-signal architecture makes CY8C24223-24SI suitable for designs that acquire sensor signals and perform local filtering or threshold decisions in one microcontroller package. The verified data confirms 24 MHz processing, 4 KB flash, 256 bytes RAM, and switch-mode pump support, but does not state ADC resolution, input ranges, sample rate, or noise figures. Those limitations must be obtained from the manufacturer datasheet and matched to the sensor output. Keep analog routing short and controlled, follow the recommended decoupling layout, and avoid assuming that the 20-pin device can replace a higher-channel or higher-resolution acquisition controller.
おすすめ
Keypad and User Interface Control
CY8C24223-24SI can support keypad scanning, LED indication, and other compact user-interface functions when the application code remains within the available 4 KB flash and 256 bytes RAM. The 24 MHz M8C core provides timing headroom for debounce logic, menu state machines, and basic peripheral coordination, while the PSoC architecture can reduce the need for separate fixed-function interface ICs. The verified data does not identify debounce intervals, timer resources, GPIO count, or display interfaces. Confirm those details in the device documentation and keep scan loops responsive without assuming unlimited RAM for display buffers or event queues.
おすすめ
Actuator and Discrete Control
The CY8C24223-24SI is appropriate for small actuator-control systems where firmware sequences relays, indicators, motors, or other discrete loads through external drivers. Its 24 MHz clock supports responsive state-machine control, while the mixed-signal resources can support feedback and threshold functions when properly configured. Because the verified records do not provide GPIO count, output drive strength, timing outputs, or logic voltage, the design must include suitable transistor or driver stages where required. Check absolute maximum ratings and switching timing in the manufacturer datasheet, and provide protection against inductive transients rather than driving loads directly from undocumented I/O capabilities.
おすすめ
Low-Cost Consumer Interface
CY8C24223-24SI can be used in cost-sensitive consumer products that need a small amount of embedded control rather than a high-performance processor. The 8-bit core, 24 MHz operating rate, 4 KB flash, and 256 bytes RAM support firmware for local configuration, status indication, and simple sequencing. The supplied data does not verify consumer temperature range, supply range, ESD performance, or compliance status, so those requirements must be checked separately. A design should also consider package availability, programming method, and field-update requirements before committing to this compact controller.
おすすめ
Portable Measurement Device
The CY8C24223-24SI may fit portable measurement products that combine local sensing, signal conditioning, and a simple display or serial status function. Its PSoC mixed-signal array provides a platform for configurable analog and digital blocks, while the 24 MHz core handles sampling coordination and control flow. The verified records do not identify ADC performance, DAC resolution, serial protocols, or power-management modes, so engineers must confirm those specifications before selecting it for precision measurements. Keep analog and digital return paths controlled, validate calibration behavior across the required temperature range, and include external protection if the measured signal can exceed the device’s documented input limits.

設計ノート
The verified data does not state the operating voltage range, absolute maximum ratings, or power-consumption figures. Before layout release, obtain the manufacturer specifications and verify the regulator, decoupling capacitors, and supply sequencing against the selected power rail. The 20-SOIC device should be placed near its supporting passives, with ground and supply return paths kept short. Do not infer safe capacitor values or voltage limits from the package or clock frequency.
Keep the PCB layout consistent with the manufacturer’s SOIC footprint and the verified 20-SOIC package designation. Place required bypass components close to the corresponding device pins, maintain a continuous ground reference beneath the part, and separate sensitive analog routing from switching or high-current paths. Because the supplied data does not include the exact pin names or recommended layout, validate the footprint and pin mapping against the manufacturer datasheet before fabrication.
The main design risk is treating distributor headline specifications as a complete device specification. The verified record confirms 24 MHz operation, 4 KB flash, 256 bytes RAM, switch-mode pump support, and a 20-SOIC package, but it does not confirm voltage, temperature, GPIO count, ADC performance, timers, or absolute maximum ratings. Check memory usage during firmware planning and resolve every data gap before making a production substitution or layout commitment.
