CY8C4124PVI-432 - 24MHz Cortex-M0 16KB PSoC 4 MCU | Infineon
部品番号: CY8C4124PVI-432 ✓ 生産中CY8C4124PVI-432 概要
A PSoC, or programmable system-on-chip, is an MCU architecture that integrates a CPU with configurable analog and digital peripherals. In the product hierarchy, the CY8C4124PVI-432 belongs to the PSoC 4 family and specifically the PSoC 4100 series. This integration lets an embedded design place sensing, signal conditioning, timing, control, and communication functions into one programmable component rather than using a separate microcontroller and several discrete interface circuits.
The principal features of the CY8C4124PVI-432 include the Arm Cortex-M0 processor operating to 24 MHz, 16 KB of flash memory organized as 16K x 8, a 12-bit successive-approximation-register ADC, and four configurable 16-bit timer, counter, and PWM blocks. Its versatile I/O system allows GPIO resources to be routed among digital and analog peripherals, supporting designs that need flexible pin assignment or board-level resource optimization.
The CY8C4124PVI-432 belongs to the PSoC 4100 performance range, which combines a modest embedded footprint with mixed-signal processing. The 12-bit SAR ADC supports analog measurement, while the configurable timers support periodic control, event counting, and PWM generation. The Arm Cortex-M0 execution environment provides a 32-bit instruction set and broad support for embedded firmware, but it should not be confused with a higher Cortex-M class that includes an instruction cache or enhanced pipeline architecture.
Typical applications include industrial sensing modules, compact control panels, automotive body and comfort subsystems, consumer appliances, and low-cost human-machine-interface controllers. The device is especially suitable when an application needs both digital control and local analog measurement without relying on a larger mixed-signal MCU or a discrete analog front end.
For PCB design, use the manufacturer pin-description table when assigning signals and confirm the SSOP-28 land pattern, power pins, ground connections, programming interface, and decoupling requirements before layout release. Keep analog and digital return paths controlled, place input and output capacitors close to their associated pins, and verify the external clock and reset configuration against the device programming requirements.
This page combines the device identity, package information, core and memory characteristics, practical application guidance, and replacement considerations into an engineering-focused reference. It also distinguishes verified device facts from replacement candidates that require additional package and peripheral validation before they can be used in a new design.

主な用途
CY8C4124PVI-432 の用途: 6 件s: Industrial Sensor Interface, Automotive Body Control Module, Compact Human-Machine Interface, Consumer Appliance Controller, Battery-Powered Monitoring Node, PWM Control and Signal Conditioning.
Industrial Sensor Interface
The CY8C4124PVI-432 fits compact industrial sensor interfaces because its 12-bit SAR ADC can acquire analog process measurements while the 24 MHz Arm Cortex-M0 core performs scaling, filtering, and control logic. Four configurable 16-bit timer, counter, and PWM blocks support periodic sampling, event counting, or actuator timing. Its 16 KB flash accommodates a focused embedded application, while routable GPIO resources simplify connections between the sensor interface and external conditioning or communications circuitry. The 28-pin SSOP package also helps reduce board area in densely populated industrial control assemblies.
おすすめ
Automotive Body Control Module
The CY8C4124PVI-432 is appropriate for small body-control, comfort, and auxiliary automation functions where a Cortex-M0 controller must combine digital inputs with limited analog measurement. Its 24 MHz processing rate supports ordinary control logic, and the four configurable 16-bit timer blocks can manage repetitive timing, debouncing, and PWM tasks. The 12-bit SAR ADC can monitor sensor or feedback signals, while the 28-pin SSOP package supports compact controller boards. Automotive qualification and the applicable temperature range must be confirmed for the exact orderable part before production use.
おすすめ
Compact Human-Machine Interface
The CY8C4124PVI-432 can support compact human-machine-interface controllers that combine button or encoder input, status indication, and local analog sensing. The 24 MHz Cortex-M0 processor provides responsive handling of user events, while the four configurable 16-bit timer/counter/PWM blocks can drive display scanning, indicator timing, or simple haptic control. Its 12-bit SAR ADC can read analog controls or sensors without a separate converter, and routable GPIO allows a board designer to map functions to available pins. The 16 KB flash is suitable for focused interface firmware rather than large graphical applications.
おすすめ
Consumer Appliance Controller
The CY8C4124PVI-432 suits cost-sensitive appliance controllers that need a small processor, local analog measurement, and several timing outputs in one package. Its 24 MHz Cortex-M0 core can execute motor or valve sequencing, button handling, and basic product logic, while the four configurable 16-bit timer blocks provide resources for PWM-driven loads and periodic maintenance functions. The 12-bit SAR ADC supports sensing tasks such as temperature, level, or feedback measurement. The 28-pin SSOP package helps reduce board size, although final environmental and lifecycle requirements should guide production sourcing.
おすすめ
Battery-Powered Monitoring Node
The CY8C4124PVI-432 can form the basis of a small monitoring node when local measurement and low-complexity processing are required in one package. Its 12-bit SAR ADC can sample sensors, and the 24 MHz Cortex-M0 core can perform threshold checks, local data formatting, and low-rate control functions. The four configurable timer blocks support scheduled measurement and wake-oriented timing. Its 16 KB flash provides a defined firmware budget, while the compact 28-pin SSOP package is useful for space-constrained monitoring products. Low-power operating modes and current consumption must be evaluated from the manufacturer datasheet for the intended duty cycle.
おすすめ
PWM Control and Signal Conditioning
The CY8C4124PVI-432 is useful in mixed-signal modules that combine adjustable control outputs with measured inputs. Four configurable 16-bit timer, counter, and PWM blocks can produce periodic or variable-duty-cycle control signals, while the 12-bit SAR ADC provides a local measurement channel. The 24 MHz Cortex-M0 core can implement scaling, filtering, fault detection, and supervisory logic. Its routable GPIO architecture helps place analog and digital functions according to board constraints. For precision timing or safety-critical outputs, verify timer resolution, output accuracy, and environmental limits in the manufacturer documentation before committing the design.

設計ノート
Use the manufacturer SSOP-28 land pattern and pin-description table as the controlling references for PCB layout. Confirm pin 1 orientation, programming signals, supply pins, ground pins, and analog-capable GPIO assignments before routing. Place input and output capacitors close to the associated device pins, keep analog traces short, and route return currents without crossing high-current switching paths to reduce noise coupling into the 12-bit SAR ADC.
Treat analog inputs and digital programming or switching signals as separate layout domains. Use a continuous ground reference, minimize analog trace length, and place the ADC source network where its resistance and capacitance do not interfere with the acquisition settling time required by the 12-bit SAR converter. If an external clock is used, keep the clock path short and away from analog inputs to reduce coupling into sampled measurements.
Determine the operating supply range, decoupling network, and startup behavior from the manufacturer datasheet before fixing the power architecture. Because the CY8C4124PVI-432 mixes analog measurement with digital control, local supply filtering should prevent peripheral switching or motor-drive noise from appearing at the analog inputs or corrupting ADC readings. Confirm programmed brownout, reset, and clock settings as part of the production firmware configuration.
Do not assume that a related PSoC 4 order code is a drop-in replacement. Compare package dimensions, pin names, power pins, programming interface, flash size, SRAM, ADC channels, timer resources, clock limits, and temperature or qualification options between the exact MPNs. A firmware image may also require adaptation when peripheral assignments or memory sizes differ, even if the underlying software architecture remains similar.
