CY8C4124PVI-442 - 24MHz PSoC 4 MCU | Infineon

A PSoC, or programmable system-on-chip, is an MCU architecture that integrates a CPU with configurable analog and digital functional blocks. In the broader semiconductor hierarchy, it is a 32-bit microcontroller and embedded processor, with the Cortex-M0 core providing a compact, low-complexity platform for control-oriented products. Unlike a fixed-function analog IC or a simple logic device, the CY8C4124PVI-442 can route GPIO and internal peripheral signals through a programmable digital fabric while adding dedicated analog conversion resources.
The 16 kByte flash provides program storage for embedded firmware, while 4 kByte of SRAM supports working memory, stack operations, and data buffers. The 24 GPIOs allow the device to interface with sensors, actuators, human-machine-interface components, and communication peripherals. The 12-bit SAR ADC provides 4,096 possible digital codes and is specified at up to 806 ksps, allowing it to sample rapidly varying analog inputs. This combination is useful in sensor interfaces, industrial controls, compact consumer products, and embedded human-machine-interface systems.
The Arm Cortex-M0 core is a 32-bit embedded processor designed for efficient control workloads. Its 24 MHz operating rate, programmable peripherals, and GPIO-to-peripheral routing reduce the need for separate analog and digital components in a compact design. Because the analog conversion function and programmable logic are integrated, board partitioning can be simplified when the application does not require the resources of a larger Cortex-M3 or Cortex-M4 MCU.
Typical applications include industrial sensor acquisition, programmable analog front ends, motor and actuator control, compact control panels, embedded user interfaces, and low-to-medium-cost consumer devices. The 28-pin SSOP package also supports designs where a conventional through-hole or leaded package is preferred over a fine-pitch QFN. Firmware and peripheral configuration should be validated for the exact clock, pin, and analog-routing requirements of the product.
A key design consideration is that the ADC, GPIO, and internal peripherals must be assigned through the device configuration before firmware operation. Confirm the selected package pinout, analog routing, clock limits, decoupling requirements, and programming-device support in the manufacturer documentation before layout release. This page also organizes the verified device specifications, sourcing guidance, design considerations, and package information into a single engineering reference.

典型應用
CY8C4124PVI-442 適用於 6 應用s: Industrial Sensor Acquisition, Programmable Analog Control Front End, Compact HMI and Keypad Controller, Motor and Actuator Control, Embedded Data Logger, Low-Cost Consumer Control Module.
Industrial Sensor Acquisition
The CY8C4124PVI-442 fits compact sensor-acquisition systems that need rapid conversion without a separate ADC. Its 12-bit SAR ADC operates up to 806 ksps, while 24 GPIOs support digital sensors, threshold inputs, status indicators, and actuator outputs. The 28-pin SSOP package allows a leaded footprint where fine-pitch QFN assembly is undesirable. Engineers should validate the sensor output range, required acquisition time, input filtering, and analog routing before selecting the exact device configuration.
Programmable Analog Control Front End
The programmable analog and digital architecture of the CY8C4124PVI-442 allows a compact front end to combine measurement and control functions on one device. Its 12-bit SAR ADC supports sampling up to 806 ksps, while configurable peripherals and 24 GPIOs can connect control outputs, status signals, and external components. This arrangement can reduce board partitioning when the application does not require high-resolution conversion or the processing capacity of a larger Cortex-M MCU.
Compact HMI and Keypad Controller
The CY8C4124PVI-442 is suitable for a compact human-machine-interface controller when the design requires 24 GPIOs and limited embedded code space. GPIO resources can serve keypad scanning, display-control signals, indicators, and communication links, while the 4 kByte SRAM supports local buffers and the 16 kByte flash holds firmware and configuration data. The 28-pin SSOP package is useful for assemblies that favor a conventional leaded package and straightforward board routing.
Motor and Actuator Control
The CY8C4124PVI-442 can support basic motor, valve, and actuator-control functions through its four configurable 16-bit timer, counter, and PWM blocks and 24 GPIOs. A 24 MHz Cortex-M0 core provides the control-processing foundation, while programmable digital routing helps connect timers and external interfaces. Design work should include checks for timer output placement, PWM frequency, fault handling, driver supply requirements, and the timing margin available in the final firmware.
Embedded Data Logger
The CY8C4124PVI-442 can form the control core of a small embedded data logger that samples analog inputs and records operating information. The 12-bit SAR ADC reaches up to 806 ksps, allowing rapid acquisition when needed, while 16 kByte flash and 4 kByte SRAM support firmware, parameters, and short-term data buffering. For continuous logging, external nonvolatile storage may be required because the internal memory capacity is modest for extended histories.
Low-Cost Consumer Control Module
The CY8C4124PVI-442 is applicable to compact consumer-control modules that combine an analog measurement with several digital interfaces. Its 24 GPIOs, 12-bit ADC, configurable timers, and 16 kByte flash can support appliance controls, lighting interfaces, or simple product functions. The 28-pin SSOP package supports cost-oriented leaded assembly, but final suitability depends on supply limits, temperature requirements, ESD expectations, and whether the internal memory is sufficient for the production firmware.

設計說明
Assign the PCB from the exact 28-pin SSOP package drawing and manufacturer pin-description table. Confirm supply, ground, reset, programming/debug, analog, clock, and GPIO functions for CY8C4124PVI-442 before routing. Do not reuse a pin map from another PSoC 4100 package because the same peripheral capability may appear on different pins. Keep sensitive analog traces short and isolate them from switching nodes wherever the device layout guidance permits.
Follow the manufacturer requirements for supply bypassing, analog-supply connections, and internal regulator configuration. Place required decoupling capacitors adjacent to the relevant package pins with short ground paths, and verify the final network against the 24 MHz clock and ADC operating conditions. Since the exact operating-voltage range is not stated in the available product summary, do not select power-source or level-shifting components until the electrical-characteristics table has been checked.
Treat analog inputs, external clock signals, and high-speed switched outputs as separate layout concerns even on this mixed-signal MCU. Use short traces for sensitive analog nets, provide a quiet ground-return path, and keep switching loops compact. For the 12-bit SAR ADC, calculate acquisition time from the source impedance and sampling rate, then validate settling and filtering in hardware; the 806 ksps maximum does not guarantee equivalent accuracy for every source network.
Avoid designing around unverified assumptions about suffix codes, temperature ratings, or package pin compatibility. CY8C4124PVI-442T is listed as a related ordering form, but it should not be substituted without checking the manufacturer ordering table. Also budget firmware and SRAM carefully: 16 kByte of flash and 4 kByte of SRAM are modest for projects with large middleware, display buffers, logging functions, or extensive connectivity stacks.
