CY8C4244AZI-443 - 48MHz Cortex-M0 MCU | Infineon
MPN： CY8C4244AZI-443 ✓ 啟用中CY8C4244AZI-443 概覽
A microcontroller is a semiconductor device that integrates a processor core, memory, and peripherals into one compact component. The PSoC 4 family belongs to the broader embedded-processing hierarchy of Cortex-M microcontrollers, mixed-signal controllers, and programmable system-on-chip devices. Compared with a fixed-function logic controller, the CY8C4244AZI-443 allows firmware to configure digital routing, analog conversion, and communication behavior, making it suitable for compact embedded systems that need more adaptability than simple discrete control circuits.
The headline features are a 48 MHz Arm Cortex-M0 core, 16 kByte flash, 4 kByte SRAM, and a 12-bit ADC. The Arm Cortex-M0 architecture provides a 32-bit instruction set while retaining a simple, low-power embedded design profile. The 12-bit ADC supports analog measurement tasks such as sensing voltage, temperature, and resistive sensors through external conditioning networks. The manufacturer classifies the device as a PSoC 4200-series member with Arm Cortex-M0/M0+ capability and programmable system-on-chip resources.
This MCU is intended for industrial control, sensor-interface, communication, and embedded user-interface designs. Its combination of flash, SRAM, and ADC resources allows a single device to acquire analog measurements, run control algorithms, and manage digital peripherals without requiring a separate ADC. The 48 MHz clock supports time-sensitive event handling, while the programmable digital fabric can route signals to timers, serial interfaces, and other peripheral blocks.
Typical uses include condition-monitoring equipment, compact industrial controllers, keypad and capacitive-touch interfaces, building automation modules, and low-cost embedded control boards. Designers should allocate the small 4 kByte SRAM carefully, place analog inputs away from fast-switching digital traces, and follow the manufacturer pin-description and layout guidance when assigning package leads.
For new PCB designs, verify the exact package drawing and pin assignments before layout because the manufacturer product summary and distributor listing describe the package differently. Firmware selection should also account for the 16 kByte flash limit, peripheral resource allocation, clock configuration, and the 12-bit ADC conversion requirements of the intended control loop.
This page consolidates the confirmed device parameters, package considerations, sourcing paths, and engineering-oriented guidance into a practical reference for designers evaluating the CY8C4244AZI-443 for embedded control and mixed-signal applications.

典型應用
CY8C4244AZI-443 適用於 6 應用s: Industrial Sensor Acquisition, Building Automation Control, Communication Interface Module, Capacitive-Touch User Interface, Condition Monitoring Controller, Compact Equipment Controller.
Industrial Sensor Acquisition
The CY8C4244AZI-443 fits compact sensor-acquisition systems that require measurement and local control in one device. Its 12-bit ADC can digitize conditioned analog inputs, while the 48 MHz Arm Cortex-M0/M0+ core performs filtering, thresholding, and control calculations. The 4 kByte of SRAM supports sample buffers and working variables, while 16 kByte of flash holds application firmware. Designers should budget memory carefully, use a stable ADC reference arrangement, and isolate sensitive analog traces from switching nodes to preserve measurement quality.
推薦
Building Automation Control
The CY8C4244AZI-443 is suitable for compact building-automation modules that combine sensor monitoring with digital control functions. Its 48 MHz Cortex-M0/M0+ processor can service timers, serial communication, and event-driven logic, while the 12-bit ADC handles analog feedback from temperature, light, or occupancy-sensing circuits. With 16 kByte of flash and 4 kByte of SRAM, the device fits moderate control firmware rather than complex gateways. Firmware growth, protocol overhead, and future features should be checked against the memory limits before design freeze.
推薦
Communication Interface Module
The CY8C4244AZI-443 can form the core of a compact protocol-conversion or field-interface module. Its 48 MHz Arm Cortex-M0/M0+ core provides sufficient instruction throughput for framing, checksums, buffering, and device-state management, while the PSoC programmable architecture supports digital peripheral routing. The available 4 kByte of SRAM must accommodate the protocol stack, receive and transmit buffers, and stack overhead; the 16 kByte flash limit should include boot code and updates. Choose a larger-memory member when buffers or multiple protocol stacks exceed this footprint.
推薦
Capacitive-Touch User Interface
The CY8C4244AZI-443 can support compact capacitive-touch and keypad interfaces when the design requires analog sensing, scanning, and control logic in one microcontroller. The 12-bit ADC contributes analog measurement capability, while the 48 MHz core can scan inputs and update indicators or communicate button events. Signal conditioning, electrode geometry, and guard routing are as important as the MCU selection, so follow the manufacturer's touch-controller configuration and layout guidance. Confirm available programmable digital blocks and SRAM allocation before committing to a touch-centric design.
推薦
Condition Monitoring Controller
The CY8C4244AZI-443 is appropriate for condition-monitoring controllers that evaluate analog sensor signals and implement threshold or control logic. Its 12-bit ADC supplies the measurement interface, and the 48 MHz processor can handle sampling schedules, filtering, and state updates. Four kBytes of RAM are adequate for a controlled set of samples and variables, but not large offline logging buffers. For extensive data retention or higher-resolution acquisition, select a device with more memory and confirm the required analog performance using the manufacturer documentation.
推薦
Compact Equipment Controller
The CY8C4244AZI-443 can serve as the primary controller in compact equipment where local sequencing, analog sensing, and communications must share one microcontroller. Its 48 MHz Arm Cortex-M0/M0+ core supports responsive task execution, the 12-bit ADC interfaces with sensor inputs, and the PSoC peripheral architecture reduces the need for separate glue logic. The 16 kByte flash and 4 kByte SRAM require disciplined code sizing and firmware updates. Validate timing margins, reset behavior, and peripheral allocation against the complete system specification.

設計說明
Resolve the package description discrepancy before committing PCB lands. The Infineon product summary identifies a TQFP-44 package, while the exact-MPN distributor listing identifies a 48-TQFP, 7 x 7 mm package. Download the ordering information and package drawing, then use the manufacturer pin-description table to assign every power, ground, programming, and peripheral connection.
Plan decoupling from the electrical characteristics in the manufacturer datasheet rather than assuming generic values for this microcontroller. Place the required input and bypass capacitors adjacent to their associated supply pins, provide a stable return path, and keep sensitive analog supply connections separate from noisy digital activity where the package and board architecture permit.
Do not treat 16 kByte of flash and 4 kByte of SRAM as interchangeable resources. Include the startup code, interrupt handlers, peripheral middleware, application logic, stack, and update margin in the flash budget. Track peak SRAM use during interrupts and communication bursts. Moving to a higher-memory family member may be necessary when software requirements expand.
Route analog inputs away from clocks, switching nodes, and high-current return paths. Use a quiet ground strategy, minimize loop area around the ADC input network, and follow the manufacturer reference layout for sensitive PSoC 4 designs. Validate the complete board with the intended clock and peripherals active because peripheral configuration can change the analog noise environment.
