CY8C4124AZI-443 - 24MHz PSoC 4 MCU | Infineon
N.º de pieza: CY8C4124AZI-443 ✓ ActivoCY8C4124AZI-443 Descripción general
A PSoC, or Programmable System-on-Chip, combines a microcontroller CPU with configurable analog and digital peripherals on one integrated device. The CY8C4100 series belongs to the broader embedded-controller hierarchy: microcontroller → mixed-signal MCU → programmable system-on-chip. Its integrated analog front end and configurable peripherals can reduce external component count in sensing, control, and embedded interface applications.
The CY8C4124AZI-443 operates at 24 MHz and provides 16 KB of flash organized as 16K x 8 bits. Its 36 I/O pins support connections to external sensors, controls, communications devices, and digital peripherals. The integrated 12-bit SAR ADC supports conversion rates up to 806 ksps, making the device suitable for applications that repeatedly acquire analog measurements while also perform control and data-processing tasks.
The device is based on the Arm Cortex-M0 architecture, a compact 32-bit processor designed for cost-sensitive embedded control. PSoC 4 devices combine that processor core with programmable mixed-signal resources rather than relying only on fixed peripheral functions. This architecture allows designers to implement sensing, signal conditioning, control logic, and communications interfaces within a compact integrated circuit.
Typical uses include industrial sensor nodes, temperature-measurement systems, analog control loops, compact instrumentation, motor-control interfaces, and connected embedded products. The 806 ksps ADC capability is especially relevant to applications that need faster analog sampling than a basic low-rate sensor interface. The 36 available I/O pins also allow the MCU to supervise several discrete inputs and outputs while retaining dedicated resources for external communication.
PCB planning should account for the 48-pin TQFP footprint, exposed programming interface requirements, power and ground distribution, and analog-signal routing around the SAR ADC. Keep sensitive analog inputs away from fast-switching digital paths, provide local supply bypassing at the device pins, and follow the manufacturer pin-description and layout guidance before assigning board functions.
This page consolidates the core PSoC 4 specifications, practical application guidance, sourcing information, and the constraints involved in identifying a pin-compatible replacement. Review the Infineon product documentation and datasheet before finalizing clock, memory, peripheral, package, and PCB decisions.

Aplicaciones típicas
CY8C4124AZI-443 es adecuado para 6 aplicacións: Industrial Sensor Acquisition, Temperature and Process Monitoring, Compact Analog Control Loops, Embedded Interface and Protocol Bridge, USB Connectivity Node, Connected Equipment Controller.
Industrial Sensor Acquisition
The CY8C4124AZI-443 fits compact sensor nodes that must acquire analog measurements and respond without a separate mixed-signal processor. Its 12-bit SAR ADC operates up to 806 ksps, while the 24 MHz Cortex-M0 core provides processing capacity for filtering, calibration, threshold evaluation, and communication tasks. The 36 I/O pins allow sensors, status indicators, and control signals to share one MCU. A practical implementation places the sensor output on a properly routed analog input, uses local supply bypassing, and separates sensitive analog traces from switching nodes to preserve measurement quality.
Recomendado
Temperature and Process Monitoring
The CY8C4124AZI-443 is suitable for temperature and process-monitoring modules requiring periodic analog conversion and centralized control. The 12-bit SAR ADC can sample up to 806 ksps, allowing multiple inputs to be serviced with a faster conversion capability than a low-rate monitoring design requires. The 24 MHz Cortex-M0 processor can apply offsets, filters, alarms, and hysteresis, while 36 I/O pins support sensor selection, relay outputs, indicators, and an upstream communications interface. Designers should verify sensor settling time and place analog components close to the MCU pins.
Recomendado
Compact Analog Control Loops
The CY8C4124AZI-443 can serve as the central controller in compact analog control loops where the system must both measure and actuate. The 806 ksps SAR ADC provides acquisition headroom for feedback signals, and the 24 MHz Arm Cortex-M0 core supports deterministic control calculations and supervisory logic. Its 36 I/O pins leave ample connections for sensors, actuators, fault indicators, and digital interlocks. The design must account for actuator drive topology, isolation from switching transients, output timing, and the regulator headroom needed by the analog and digital sections.
Recomendado
Embedded Interface and Protocol Bridge
The CY8C4124AZI-443 fits embedded interface modules that combine a protocol controller with local analog monitoring. Its 36 I/O pins and 16 KB flash provide resources for device management and lightweight protocol handling, while the integrated SAR ADC adds measurement capability without requiring a separate ADC. In a bridge design, the MCU can supervise configuration inputs, report analog status, and coordinate data transfer. Firmware and PCB planning should define signal levels, connector protection, grounding, and any required level-shifting before assigning the package pins.
Recomendado
USB Connectivity Node
The CY8C4124AZI-443 is appropriate for a compact connectivity node that needs local sensing in addition to digital communication. The 24 MHz Cortex-M0 core and 16 KB flash can manage peripheral configuration, status logic, and application-specific control, while 36 I/O pins support sensors and digital functions. A USB-connected implementation should reserve the required data signals, route them as a controlled impedance pair, provide correct bus decoupling, and keep analog paths physically separate. The exact USB electrical requirements must be confirmed against the manufacturer device documentation before layout release.
Recomendado
Connected Equipment Controller
The CY8C4124AZI-443 can support connected equipment where a controller must combine digital supervision with occasional analog measurements. Its 36 I/O pins allow operation of status inputs, control outputs, and communication lines, while the 12-bit SAR ADC adds monitoring of supply, position, or process-related signals. The 24 MHz core provides sufficient sequential control bandwidth for non-real-time supervisory functions. A production design should use the manufacturer power and decoupling recommendations, establish a controlled ground structure, and test startup behavior across the complete input range and required environmental conditions.

Notas de diseño
Route the 48-pin TQFP footprint using the manufacturer package drawing and pin-description table. Place the device so that power, ground, programming, and analog signals can be connected without long loops. Keep analog inputs away from digital clocks, high-speed edges, and switching-supply components; use a continuous ground reference where possible and place decoupling components close to the relevant supply pins.
Plan the supply network around the voltage range, current requirements, and sequencing conditions listed in the manufacturer documentation. Place bulk and local bypass capacitors according to the recommended application circuit rather than relying on general-purpose values. Validate startup and shutdown behavior across the full supply range, especially if analog sensors remain active while the MCU enters a low-power state.
The 12-bit SAR ADC can sample as fast as 806 ksps, so analog trace length, source impedance, grounding, and settling time must be treated as a signal-integrity problem. Keep the analog path short, minimize loop area, separate it from switching nodes, and use an RC filter when the sensor source impedance would otherwise slow the conversion. Verify acquisition time and ADC accuracy with the intended source network.
Do not select a candidate solely because it uses a 48-pin TQFP. A valid drop-in replacement must also match the pin functions, clock behavior, memory configuration, PSoC peripheral assignments, programming method, and package geometry. Changes to firmware, boot configuration, or analog routing can turn an apparently similar MCU into a redesign, so validate any substitution against the complete manufacturer documentation.
