CY8C3666AXI-202 - 67MHz PSoC 3 MCU | Infineon | 100-TQFP
部品番号: CY8C3666AXI-202 ✓ 生産中CY8C3666AXI-202 概要
A PSoC 3 is a mixed-signal microcontroller that combines a CPU, programmable digital blocks, analog resources, and specialized peripherals in one integrated circuit. The MCU belongs to the hierarchy 8051 microcontroller, embedded microcontroller, programmable system-on-chip, and integrated semiconductor. Unlike a general-purpose 8051 device, it provides configurable peripheral resources and a hardware hub for connecting blocks within the chip.
The verified feature set includes a single-core 8051 processor rated up to 67 MHz, 64 kByte of flash organized as 64K x 8, 8 kByte of SRAM, and 2 kByte of data EEPROM. The device also provides 27 interrupt sources with eight priority levels, one Peripheral Hub Unit with eight parallel access paths, and two data pointers. These resources support interrupt-driven control, data acquisition, communications, and programmable signal-processing tasks.
The 62 GPIOs make the CY8C3666AXI-202 suitable for devices requiring numerous external connections, including service robots and embedded control systems. Its 100-TQFP package provides substantially more I/O than smaller microcontroller packages while retaining a conventional leaded footprint that can be assembled using standard surface-mount production methods. Operating voltage information available from distributor results identifies a 5.50 V maximum device rating, but detailed electrical limits still require confirmation in the manufacturer datasheet.
Typical embedded applications include service-robot control, industrial interface modules, sensor-heavy control boards, programmable input and output systems, and compact consumer equipment. Designers should preserve the peripheral routing and pin constraints of the PSoC 3 architecture, verify the unused pins and power requirements against the datasheet, and confirm that the selected development toolchain supports the CY8C36xx device family.
This page consolidates the verified manufacturer and distributor details for the CY8C3666AXI-202 and separates documented specifications from unavailable pricing, pin-level data, and regulatory details. It also provides practical application and design guidance for evaluating the MCU before committing a PCB layout or production order.

主な用途
CY8C3666AXI-202 の用途: 6 件s: Service Robot Control, Industrial Sensor Interface, Programmable Logic Controller, Embedded Communications Gateway, Consumer Interface Controller, Robotics Sensor Fusion Hub.
Service Robot Control
The CY8C3666AXI-202 fits service-robot control because the manufacturer identifies service robots as a target application and the MCU provides 62 GPIOs. That I/O capacity can accommodate limit switches, proximity sensors, encoders, indicator drivers, and communication interfaces without requiring a separate high-pin-count expansion device. The 67 MHz 8051 CPU supports responsive control logic, while 8 kByte of SRAM handles working state and 64 kByte of flash stores application code. A practical design should allocate GPIOs through the PSoC configuration and avoid assuming that every port signal is available independently of the selected peripheral functions.
Industrial Sensor Interface
The 62-GPIO CY8C3666AXI-202 is appropriate for centralized industrial sensor acquisition where many discrete inputs and outputs must converge on one controller. A PSoC 3 system-on-chip can combine configurable digital logic with programmable analog and peripheral resources, reducing the need for separate interface logic in suitable designs. Its 27 interrupt sources and eight priority levels allow time-sensitive inputs to be serviced systematically. Designers should confirm the exact analog functions, comparator resources, and routing limitations in the manufacturer datasheet, then isolate external signals appropriately for the target industrial environment.
Programmable Logic Controller
The CY8C3666AXI-202 can serve as the central controller in a compact programmable logic platform because its PSoC architecture combines an 8051 processor with configurable digital blocks and a Peripheral Hub Unit. The 64 kByte flash and 2 kByte data EEPROM provide code and parameter storage, while 62 GPIOs offer substantial panel and machine-facing connectivity. Firmware can sequence actuators, debounce inputs, and implement diagnostic states without an external CPLD. Firmware developers should use the supported PSoC configuration workflow and validate that each selected GPIO, clock, and interrupt assignment remains available in the final device configuration.
Embedded Communications Gateway
The 67 MHz CY8C3666AXI-202 is suitable for an embedded communications gateway that must combine protocol handling, local control, and multiple digital interfaces. Its 64 kByte flash supports a meaningful embedded application, the 8 kByte SRAM supports buffering and stack space, and the 62 GPIOs can support status indicators, configuration lines, or external transceiver control. The available data does not identify a dedicated Ethernet or USB interface, so communications implementation must be based only on peripherals explicitly present in the CY8C36xx documentation. Designers should also budget memory for buffering and ensure protocol timing remains deterministic under interrupt load.
Consumer Interface Controller
The CY8C3666AXI-202 can be used in a consumer product as a compact interface controller for buttons, displays, indicators, and externally controlled functions. The PSoC 3’s combination of an 8051 CPU, programmable hardware, and 62 GPIOs allows product logic and input handling to share one device, reducing board area relative to a CPU-only design. The 100-TQFP package is larger than a minimal microcontroller package but remains practical for leaded surface-mount assembly. Before layout approval, verify package dimensions, exposed-pad or thermal requirements, pin multiplexing, and all power pins against the official datasheet.
Robotics Sensor Fusion Hub
The CY8C3666AXI-202 can act as a robotics sensor hub because its 62 GPIOs provide ample connections for digital sensors, actuator interlocks, and status signals. The 8051 CPU running up to 67 MHz can combine sensor readings, apply control logic, and publish machine state, while the PSoC peripherals can implement time-sensitive acquisition functions. Its 8 kByte of SRAM is sufficient for compact state variables but not unrestricted high-rate data buffering, so raw sensor streams may require external memory or a streaming architecture. System planners should quantify latency, interrupt priority, and data bandwidth before committing to this MCU.

設計ノート
Design the 100-TQFP footprint directly from the manufacturer package drawing rather than relying on a generic 100-pin library symbol. The verified package is 14 x 14 mm, but body dimensions, lead width, pitch, and pin numbering must still be checked against the datasheet. Review every multiplexed GPIO and power-ground assignment before routing because a valid package position may not be available for the function assigned by the PSoC configuration.
Use the manufacturer’s recommended power pins, decoupling network, and voltage limits when establishing the supply rail. The available distributor information confirms a 5.50 V maximum operating voltage, but it does not provide the minimum operating voltage, current limits, or permitted power configurations. Place required bypass capacitors adjacent to the relevant supply pins and verify startup behavior, analog-supply requirements, and peripheral-specific rails against the official datasheet before schematic release.
Do not treat every nominal GPIO as independently usable without checking the device configuration. PSoC peripherals share pins and internal routing resources, so a valid-looking 100-TQFP assignment can become unavailable after clocks, interrupts, analog functions, or dedicated outputs are selected. Export the final configuration, compare its generated pin map with the schematic, and run a build-time or design-review check that prevents assignments conflicting with reserved package functions.
