CY8C5567AXI-019 - 67MHz PSoC 5 MCU | Infineon Technologies
料号： CY8C5567AXI-019 ✓ 量产中CY8C5567AXI-019 概述
A PSoC 5, or Programmable System-on-Chip, combines a microcontroller core with programmable digital and analog peripheral blocks in one integrated circuit. Within the semiconductor hierarchy, it is a microcontroller and embedded processor; within the PSoC family, it provides a configurable platform for mixed-signal control, communications, and signal-processing designs.
The CY8C5567AXI-019 belongs to the CY8C55 series and provides a 32-bit processing architecture, a 67 MHz maximum clock frequency, and 128 KB of flash storage. Its 100-pin TQFP package exposes substantially more device connections than smaller microcontroller packages, making it appropriate for systems that require numerous external interfaces while remaining compatible with conventional surface-mount assembly.
Programmable system-on-chip architecture allows designers to allocate peripheral resources according to the application rather than relying on a fixed combination of dedicated interface blocks. This architecture is useful when a design needs adaptable digital control, analog measurement, communications, or timing functions implemented within a single microcontroller package.
Typical application areas include industrial monitoring and control, connected sensor equipment, embedded automation, consumer devices, communication equipment, and general-purpose embedded control. The 128 KB of flash provides a defined code-storage region for firmware, while the 100-pin package supports the larger pin count often needed for external sensors, communications links, status indicators, and actuators.
PCB implementation should follow the manufacturer’s land pattern, pin-connection table, and recommended decoupling guidance. Pay particular attention to supply routing, analog and digital return paths, exposed programming or test connections, and the package’s thermal requirements. The 14 mm by 14 mm footprint is physically larger than common 48-pin and 64-pin MCU packages, so enclosure and connector spacing should be checked before layout release.
This page consolidates the verified device identity, core architecture, memory capacity, clock rate, package information, sourcing workflow, and engineering guidance into one decision-oriented reference. It also distinguishes the exact ordered MPN from its tape-and-reel packaging variant while avoiding unrelated parts that do not share a verified drop-in footprint.

典型应用
CY8C5567AXI-019 适用于 6 应用s: Industrial Monitoring and Control, Connected Sensor Equipment, Embedded Automation Equipment, Communication Equipment, Consumer Control Devices, General-Purpose Embedded Control.
Industrial Monitoring and Control
CY8C5567AXI-019 fits industrial monitoring and control equipment that benefits from a 32-bit Cortex-M3 processor, programmable PSoC peripherals, and a 100-pin interface-rich package. The processor operates up to 67 MHz, while 128 KB of flash provides a defined firmware-storage region for acquisition, control, event logging, and communications routines. Use the 100-pin TQFP to connect sensors, isolated communication links, status indicators, and actuator drivers. Validate the device’s operating-voltage and temperature limits against the industrial environment before production release.
推荐
Connected Sensor Equipment
The CY8C5567AXI-019 is suitable for connected sensor equipment that must combine measurement control, programmable signal handling, and external communications. Its Arm Cortex-M3 core provides 32-bit processing up to 67 MHz, while the PSoC 5 architecture supports configurable digital and analog peripheral functions. The 100-pin package can accommodate sensor inputs, conditioning circuitry, communication interfaces, and status signals. Firmware should define the peripheral configuration and verify acquisition timing against the application’s accuracy and latency requirements.
推荐
Embedded Automation Equipment
CY8C5567AXI-019 can serve as the control center for embedded automation equipment requiring deterministic peripheral handling and a generous pin count. Its 67 MHz maximum clock rate supports responsive sequencing, communications, and supervisory logic, while 128 KB of flash stores application firmware. The 100-pin TQFP gives designers access to a broad set of device connections for encoders, switching inputs, outputs, and bus transceivers. Confirm pin multiplexing, power requirements, and timing margins in the manufacturer documentation before PCB release.
推荐
Communication Equipment
CY8C5567AXI-019 is applicable to communication equipment where an embedded protocol stack must coexist with configurable peripheral functions. The 32-bit Arm Cortex-M3 core operates up to 67 MHz, and 128 KB of flash provides storage for firmware and communication routines. Its 100-pin package supports connections among transceiver interfaces, indicators, controls, and service signals. The PSoC 5 feature set should be configured according to the selected peripherals, and signal-integrity and timing requirements should be verified separately from the processor clock specification.
推荐
Consumer Control Devices
CY8C5567AXI-019 can support consumer control devices that combine user interfaces, programmable logic, sensing, and external device connections in one embedded platform. Its 67 MHz Cortex-M3 core provides more processing headroom than a simple state-machine controller, and the 128 KB flash capacity supports a larger embedded application. The 100-pin TQFP requires more board area than a compact MCU, so confirm enclosure dimensions. Product-specific electrical limits, peripheral availability, and lifecycle suitability should be checked before committing the device to a high-volume consumer design.
推荐
General-Purpose Embedded Control
CY8C5567AXI-019 is a general-purpose embedded controller for products that need more processing capability and I/O flexibility than a small 8-bit or low-pin-count MCU. The 32-bit Cortex-M3 core runs up to 67 MHz, the device contains 128 KB of flash, and its programmable system-on-chip architecture allows peripheral resources to be assigned according to the application. The 100-pin package helps when multiple external signals are required. Firmware partitioning, clock-tree configuration, and pin multiplexing should follow the manufacturer’s PSoC 5 design guidance.

设计说明
Use the manufacturer’s exact 100-pin TQFP land pattern and pin table rather than a generic TQFP footprint. Begin schematic assignment with supply, ground, programming, clock, reset, and communication functions, then assign peripheral signals according to the selected PSoC configuration. The 14 mm by 14 mm package requires additional routing space around its edges and may affect connector placement or enclosure clearance.
Plan the power tree before assigning signal pins. Follow the manufacturer’s recommended bypass-capacitor network, place each decoupling component directly at its assigned supply pins, and provide a low-impedance return path for every supply domain. The 67 MHz CPU rating is a maximum processing specification rather than a substitute for verified clock, voltage, and operating-condition requirements.
Separate clock, programming, communications, and general-purpose peripheral routing where practical, especially when the design also performs precision analog measurement. Keep sensitive signal paths short, avoid routing them beneath switching nodes or noisy return currents, and observe the manufacturer’s guidance for exposed programming and test functions. Review final pin multiplexing after PSoC peripheral configuration is fixed.
Do not treat CY8C5567AXI-019 and CY8C5567AXI-019T as different electrical designs merely because their suffix differs; the verified listings show the same core, frequency, flash capacity, and package. Conversely, do not substitute the part without checking the approved BOM and incoming packaging requirements. Also avoid assuming that similarly named PSoC or Cortex-M3 devices are pin-compatible without comparing every assigned pin and electrical limit.
