CY8C4014SXI-420 - 16MHz 16KB Flash PSoC 4 | Infineon
Référence : CY8C4014SXI-420 ✓ ActifCY8C4014SXI-420 Présentation
A PSoC is a mixed-signal microcontroller that integrates programmable analog blocks, digital peripherals, and a CPU into one device. Within the broader semiconductor hierarchy, the CY8C4014SXI-420 is a programmable system-on-chip, an MCU, a microcontroller IC, and an embedded-control component. This integration can reduce external component count while allowing functions such as touch sensing, control logic, and low-speed communication to be consolidated on a compact board.
Key device attributes include a 32-bit Arm Cortex-M0 processor operating at 16 MHz, 16 kByte of flash, 2 kByte of SRAM, CAPSENSE support, and an 8-SOIC package. The target ordering code is associated with the CY8C4000 family. Infineon identifies the device as a PSoC 4 MCU with CAPSENSE, while distributor listings describe the same 16 MHz, 16 kByte flash, and 2 kByte SRAM configuration.
The CY8C4000 architecture combines general-purpose embedded processing with programmable peripherals suited to compact control systems. Its Arm Cortex-M0 core provides a 32-bit instruction set and an established software ecosystem, while CAPSENSE enables capacitive sensing applications using external sensor electrodes. The 8-pin SOIC package is useful where a small PCB footprint, conventional surface-mount assembly, and access to a limited number of general-purpose and special-function pins are required.
Typical uses include capacitive touch controls, compact human-interface modules, DC brushless or SRM motor-control systems, appliance controls, sensor interfaces, and small industrial or consumer embedded products. For designs using more than two electrodes or requiring additional programmable analog functions, designers should confirm the available resources and pin multiplexing in the manufacturer datasheet before committing the PCB layout.
PCB design should preserve the package pin assignments, place decoupling capacitance close to the supply pins, and route sensitive CAPSENSE electrodes away from noisy switching nodes and long parallel traces. Firmware development requires a compatible PSoC configuration environment, and the device should be programmed according to the programming and boot instructions in the manufacturer documentation. Verify all voltage, clock, and reset details against the exact ordering code before production release.
This product record combines the manufacturer identification, distributor package and memory details, CAPSENSE positioning, and ordering variants in one engineering-focused reference. It also provides structured replacement analysis, application guidance, and design checks for teams evaluating the CY8C4014SXI-420 in space-constrained embedded products.

Applications typiques
CY8C4014SXI-420 convient pour 6 applications: Capacitive Touch Controls, DC SRM Motor Control, Compact Sensor Interface, Appliance Control Module, Human Interface Module, Small Embedded Control Product.
Capacitive Touch Controls
The CY8C4014SXI-420 fits compact capacitive-control products because it combines an Arm Cortex-M0 processor running at 16 MHz with CAPSENSE support. The 16 kByte flash accommodates control firmware, while 2 kByte of SRAM supports state management and signal processing for touch-driven user interfaces. Its 8-SOIC package also helps preserve board area in small control panels, appliance interfaces, and wearable-adjacent accessories. Use the manufacturer pin and CAPSENSE configuration guidance to assign electrodes, minimize electrode-trace capacitance, and isolate sensitive sensor nodes from switching noise.
Recommandé
DC SRM Motor Control
The CY8C4014SXI-420 is appropriate for the supervisory and control portion of a compact DC switched-reluctance motor system. Its 32-bit Arm Cortex-M0 core operates at 16 MHz, providing deterministic control logic for commutation sequencing, protection handling, and communication tasks, while the programmable mixed-signal resources support applications beyond a basic fixed-function MCU. The 2 kByte SRAM is suitable for modest real-time state, and the 8-SOIC package supports space-constrained motor-control boards. Verify exact peripheral availability, timing limits, and thermal requirements before production.
Recommandé
Compact Sensor Interface
The CY8C4014SXI-420 can act as the central controller in a small sensor-conditioning and digital-interface module. Its 16 MHz Cortex-M0 core provides sufficient arithmetic capability for sampling, filtering, state-machine control, and communication handling, while 16 kByte of flash stores application firmware and 2 kByte of SRAM supports working buffers. The programmable analog and digital characteristics of the PSoC platform can simplify consolidation of control functions around a sensor element. Use the manufacturer documentation to confirm ADC or comparator resources, I/O voltage limits, and the exact peripheral mapping for the selected board architecture.
Recommandé
Appliance Control Module
The CY8C4014SXI-420 is suitable for space-conscious appliance controls that combine local logic, user input, and configurable analog functions. The Arm Cortex-M0 processor handles sequencing and control firmware at 16 MHz, and the 16 kByte flash provides room for a compact embedded application. CAPSENSE can support touch buttons or sliders without requiring a separate dedicated controller in suitable designs. Its 8-SOIC package fits small control boards and conventional automated-board assembly. Engineers should allocate careful pin planning for power, programming, communications, sensor electrodes, and any actuator-control outputs.
Recommandé
Human Interface Module
The CY8C4014SXI-420 fits a compact human-interface module requiring responsive local control and capacitive input. The 32-bit Cortex-M0 core at 16 MHz can manage debouncing, sensor scanning, LED or display sequencing, and control-message handling, while CAPSENSE supplies the foundation for capacitive buttons. With 16 kByte flash and 2 kByte SRAM, the device targets compact rather than highly memory-intensive interfaces. Place the MCU and supporting passives close to the sensor electrode region, keep programming access reachable during production, and confirm the complete pin assignment from the manufacturer datasheet.
Recommandé
Small Embedded Control Product
The CY8C4014SXI-420 can serve as the primary controller in a small embedded product that needs programmable logic, moderate firmware storage, and mixed-signal peripherals in one package. Its 16 MHz Arm Cortex-M0 core handles real-time tasks, the 16 kByte flash stores the application, and the 2 kByte SRAM provides a compact working memory. The 8-SOIC format supports low-cost board assembly and straightforward external programming access. Before schematic release, confirm supply voltage, clock configuration, reset behavior, programming pins, and every multiplexed pin against the exact manufacturer documentation.

Notes de conception
Assign the eight SOIC pins directly from the manufacturer pin-description table and preserve access to programming and reset functions. Because several PSoC functions can share pins, freezing the peripheral map before layout reduces rerouting. Place the device where sensor, ground, and programming routes can be routed according to the manufacturer PCB guidance.
Route CAPSENSE electrodes as short, controlled-impedance paths and keep them away from switching nodes, high-current returns, and long parallel traces. The sensor performance of an 8-pin mixed-signal MCU can be affected by adjacent copper and guard structures, so follow the CAPSENSE layout recommendations in the manufacturer documentation and prototype the final electrode geometry.
Do not substitute the related CY8C4014SXI-420T solely because the base family matches. The ordering suffixes can encode different temperature or delivery characteristics, and a tape-and-reel code is not an engineering substitute by itself. Similarly, confirm the grade-specific meaning of the 420 and 421 suffixes before using either in a released design.
