CY8C3666AXI-202 সারাংশ

The Infineon Technologies CY8C3666AXI-202 is a PSoC 3 programmable system-on-chip based on an 8-bit 8051 CPU, operating up to 67 MHz and integrating 64 kByte of flash memory, 8 kByte of SRAM, and 62 GPIOs in a 100-TQFP package measuring 14 x 14 mm.

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.

সাধারণ ব্যবহার

CY8C3666AXI-202 এর জন্য উপযুক্ত 6 অ্যাপ্লিকেশনs: 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.

Where can I download the CY8C3666AXI-202 datasheet PDF?
The CY8C3666AXI-202 datasheet PDF can be downloaded from the verified manufacturer-linked document at https://media.digikey.com/pdf/Data%20Sheets/Cypress%20PDFs/CY8C3666AXI-202_Web.pdf. The document is identified as the CY8C3666AXI-202 Web PDF and states that the product is in production. It should be used as the primary source for pin assignments, electrical limits, timing, clocking, and peripheral configuration.
Where can I find the CY8C3666AXI-202 pinout?
The authoritative CY8C3666AXI-202 pinout is located in the pin-assignment section of the manufacturer datasheet at https://media.digikey.com/pdf/Data%20Sheets/Cypress%20PDFs/CY8C3666AXI-202_Web.pdf. The available search results confirm a 100-TQFP package but do not reproduce individual terminal names or numbering, so a complete 100-terminal pin list cannot be populated reliably from the supplied data. The schematic and PCB footprint must therefore be checked against the datasheet before release.
How much does the CY8C3666AXI-202 cost?
The verified CY8C3666AXI-202 price is not stated in the supplied distributor results, so no numeric quotation should be inferred from them. DigiKey and Mouser provide live product, inventory, and pricing links, while Octopart reports that it compares bulk pricing across distributors. The pricing tiers in this page use 0.00 only because the required numeric schema lacks a supplied quote; this is a data placeholder, not a claim that the component is free as of 2026-10-29.
Where can I buy CY8C3666AXI-202 online?
The CY8C3666AXI-202 can be queried from Infineon Technologies through DigiKey at https://www.digikey.com/en/products/detail/infineon-technologies/CY8C3666AXI-202/3844935 and from Infineon through Mouser at https://www.mouser.com/ProductDetail/Infineon-Technologies/CY8C3666AXI-202T. The supplied results do not contain actual order prices, current quantities, or delivery dates, so buyers should confirm commercial terms directly with the distributor as of 2026-10-29.
What is the lead time for CY8C3666AXI-202?
The verified lead time for CY8C3666AXI-202 is not disclosed in the supplied results. DigiKey’s listing uses the promotional phrase “ships today,” but that wording does not establish a contractual lead time for every quantity or every stocked package variant. For production planning, request a quantity-specific date from the distributor and confirm whether the quoted material is new, original manufacturer stock, or another authorized inventory source as of 2026-10-29.
Is CY8C3666AXI-202 in stock?
The supplied DigiKey result states that CY8C3666AXI-202 can be bought and shipped today, which indicates listing-level availability at the time of retrieval on 2026-10-29. It does not provide a warehouse quantity or guarantee inventory for higher production volumes. The manufacturer-linked datasheet also describes the device as in production, so current supply appears available, but procurement teams should verify live stock before committing a BOM.
CY8C3666AXI-202 vs CY8C3666AXI-036: which is better?
The CY8C3666AXI-202 and CY8C3666AXI-036 are both Infineon PSoC 36xxx devices with an 8051 CPU, 64 kByte of flash, and 8 kByte of SRAM. The available manufacturer results do not disclose the differentiating order-code fields for the target part, so temperature grade, speed grade, qualification, or lifecycle suitability cannot be concluded from the supplied evidence. Review both ordering pages and the datasheet before selecting between them.
What is the difference between CY8C3666AXI-202 and CY8C3666AXI-036?
The verified difference is the ordering suffix: CY8C3666AXI-202 is the target orderable MPN, while CY8C3666AXI-036 is a separately listed CY8C36xxx MCU. Both share the 8051 CPU, 64 kByte flash, and 8 kByte SRAM described in the manufacturer results. The supplied data does not identify which encoded characteristic changes between -202 and -036, so engineers must compare the complete ordering information before treating them as interchangeable.
When should I choose CY8C3666AXI-202 over CY8C3666AXI-036?
Choose CY8C3666AXI-202 when the manufacturer ordering information for that specific suffix satisfies the required temperature, qualification, and production conditions. The verified data does not expose the decoded characteristics of the -202 suffix, so it cannot support a broader technical recommendation over -036. The defensible decision is to compare the complete order-code tables, operating limits, qualification requirements, and lifecycle terms for both devices.
Is CY8C3666AXI-202 suitable for service robots?
Yes, the Infineon manufacturer page explicitly identifies service robots as an application for the CY8C3666AXI-202. Its 62 GPIOs can support numerous sensors, actuators, communication lines, and discrete control signals, while the 67 MHz 8051 CPU and 8 kByte of SRAM provide embedded processing resources. Detailed motor-control, safety, and environmental requirements still need validation against the complete device documentation and system-level constraints.
What can replace CY8C3666AXI-202?
The verified cross-reference search did not identify a cross-brand, pin-compatible replacement for the CY8C3666AXI-202. The only closely documented same-family candidate is the Infineon CY8C3666AXI-036, which shares the 8051 CPU, 64 kByte flash, and 8 kByte SRAM, but its ordering-code differences and full pin compatibility are not supplied. A drop-in substitution should therefore not be claimed until Infineon’s ordering information and the datasheet confirm it.
Can CY8C3666AXI-036 replace CY8C3666AXI-202?
CY8C3666AXI-036 may be a candidate for review, but the supplied evidence does not establish unconditional drop-in replacement. It is an Infineon CY8C36xxx MCU with the same stated 8051 CPU, 64 kByte flash, and 8 kByte SRAM, yet the -036 and -202 suffix characteristics are not decoded in the provided results. Confirm package, speed, temperature, qualification, peripheral configuration, and pin mapping in the manufacturer datasheet before substitution.
What is the best Infineon equivalent for CY8C3666AXI-202?
The best documented Infineon-family candidate is the CY8C3666AXI-036 because the manufacturer identifies it as a PSoC 36xxx MCU with an 8051 CPU, 64 kByte of flash, and 8 kByte of SRAM. However, the supplied data does not confirm that its -036 suffix preserves every electrical and qualification characteristic of the -202 device. It should therefore be treated as a review candidate, not an automatically approved drop-in replacement.
Does CY8C3666AXI-202 comply with RoHS and AEC-Q100?
The verified CY8C3666AXI-202 datasheet listing includes a “RoHS Support” reference, but the supplied snippet does not provide the actual declaration text. The target device is also not identified as AEC-Q100 qualified in the verified results. Accordingly, RoHS status and automotive qualification remain unresolved here; request the current manufacturer compliance documents before using the part in a regulated or automotive design.

নির্বাচন গাইড

Choose CY8C3666AXI-202 when a design needs the documented combination of a 67 MHz 8051 CPU, 64 kByte of flash, 8 kByte of SRAM, and 62 GPIOs in a 100-TQFP package, particularly for service robots, industrial interfaces, and programmable control systems. Review CY8C3666AXI-036 when an alternative Infineon ordering code appears attractive, but do not approve it as a drop-in replacement without confirming the meaning of the -036 suffix, complete pin mapping, operating limits, and qualification. The verified search found no cross-brand equivalent with evidence of identical pin compatibility, so changing manufacturers would require a deliberate design review rather than a simple substitution. For production, confirm live pricing, stock, and quantity-specific lead time directly with authorized distributors, and base production release on the current manufacturer datasheet and ordering table.

ডিজাইন নোট

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.
