CY8C26643-24AI Обзор

The Infineon Technologies CY8C26643-24AI is an 8-bit M8C PSoC 1 mixed-signal microcontroller with a 24 MHz maximum clock, 16 KB flash memory, and a 44-pin TQFP package. It combines an onboard controller with configurable mixed-signal resources, allowing digital control and analog functions to share one programmable system-on-chip. The verified product listing identifies the device as a 44-TQFP (10 x 10 mm) part operating at 3.3 V.

A PSoC, or Programmable System-on-Chip, is a microcontroller architecture that integrates a CPU, programmable digital blocks, configurable analog resources, and supporting peripherals into one device. In the broader semiconductor hierarchy, the CY8C26643-24AI is a microcontroller, an embedded-control IC, and a configurable mixed-signal system-on-chip. Its 8-bit M8C controller is suited to compact products that need deterministic control, serial communications, data acquisition, and local analog signal conditioning without a separate analog IC.

Key verified attributes include 24 MHz operation, 16 KB of flash organized as 16K x 8 bits, 8-bit processing, and a 44-pin TQFP package. The device is identified as part of the CY8C26xxx PSoC family and is associated with PSoC Designer and PSoC silicon. The supplied distributor data does not expose the complete set of analog blocks, GPIO count, SRAM capacity, operating-temperature limits, or peripheral ratings, so those details remain reserved for datasheet-level design verification.

The 24 MHz M8C core provides a practical balance between processing capability, power use, and implementation simplicity. Configurable analog and digital blocks allow a designer to tailor peripherals to functions such as signal conditioning, timing, control, and communications. This configurability can reduce the number of discrete components in compact embedded systems, although firmware configuration, clock planning, and analog calibration must be validated through the PSoC toolchain.

Typical uses include industrial control modules, sensor interfaces, compact instrumentation, consumer-control products, communications equipment, and embedded motor or actuator controllers. The 44-pin TQFP package provides enough external connections for mixed-signal and control-oriented designs while remaining compatible with conventional surface-mount assembly. Confirm the exact pin functions and exposed analog resources against the manufacturer datasheet before laying out a new PCB.

The principal design consideration is toolchain compatibility. PSoC configurations depend on supported PSoC Designer versions, device support, programming hardware, and application firmware. Do not treat a same-package or similarly named microcontroller as a drop-in replacement without verifying pinout, memory map, peripheral resources, interrupt behavior, and programming compatibility.

This page consolidates verified distributor specifications, sourcing links, application guidance, and replacement-verification criteria. Because the provided data does not include a manufacturer-hosted official PDF URL or a complete verified pinout, those fields are marked conservatively rather than inferred.

Типичное применение

CY8C26643-24AI подходит для 6 применениеs: Industrial Sensor Interface, Compact Instrumentation, Communications Controller, Consumer Control Module, Data Acquisition Front End, Motor and Actuator Control.

🏭

Industrial Sensor Interface

The CY8C26643-24AI fits compact sensor-interface modules because it combines an 8-bit M8C controller, configurable mixed-signal resources, and 24 MHz processing in one 44-pin TQFP device. A designer can use the programmable architecture to organize acquisition, filtering, thresholding, and digital control functions around the sensor signal. The verified data does not state ADC resolution, input bandwidth, accuracy, or GPIO count, so those specifications must be checked before selecting sample rates or analog front-end components. The 3.3 V device designation favors 3.3 V sensors and interface circuitry, provided every signal remains inside the manufacturer’s verified limits. Firmware development should use a supported PSoC Designer version and the appropriate programming hardware. Production validation should include sensor calibration, analog-noise measurements, startup behavior, and recovery from transient inputs.

🔧

Compact Instrumentation

The CY8C26643-24AI is appropriate for compact instrumentation where local control, signal conditioning, and communication must share one microcontroller platform. Its 24 MHz M8C core provides a defined operating point for embedded measurement and user-interface tasks, while the PSoC configurable resources can support analog front-end functions and programmable digital logic. The verified record does not provide measurement accuracy, converter performance, reference quality, or display-interface ratings, so those specifications require direct datasheet confirmation. Designers should reserve pins for programming and debugging, validate reference and sensor conditioning networks, and test whether the 3.3 V designation supports every external interface. Because this is a configurable mixed-signal device, the final analog and digital block allocation becomes part of the released design and should be documented alongside firmware version and tool configuration.

🌐

Communications Controller

The CY8C26643-24AI can serve as the control processor in a compact communications-oriented module when the design needs mixed-signal capability alongside an embedded controller. The 8-bit M8C core runs at up to 24 MHz, and the 44-pin TQFP package offers a defined surface-mount integration target. Before selecting the device, verify the required UART, SPI, I2C, CAN, or other interface resources in the manufacturer documentation; those peripheral details were not included in the supplied snippets. External transceiver requirements must also be checked against the verified 3.3 V device designation. Layout should isolate communication lines from sensitive analog nodes, provide the required bypass and termination networks, and preserve programming access. Firmware qualification should test protocol timing under worst-case interrupt load and across the intended voltage and temperature operating range.

📱

Consumer Control Module

The CY8C26643-24AI is a practical candidate for compact consumer-control products that combine touch, analog conditioning, timing, and actuator-control functions in a small embedded design. Its configurable mixed-signal architecture can reduce the need for separate logic and analog devices, while the 24 MHz 8-bit controller is well matched to simple control loops and finite-state logic. However, the supplied evidence does not verify touch-performance specifications, analog accuracy, GPIO availability, or consumer temperature limits. Engineers should confirm those values in the manufacturer datasheet and assess whether PSoC Designer remains supported for the product lifecycle. Firmware must preserve configuration data through programming and production test. Hardware validation should examine noise immunity, ESD response, startup sequencing, and behavior at the boundaries of the intended 3.3 V-based power architecture.

📊

Data Acquisition Front End

The CY8C26643-24AI is suited to compact data-acquisition front ends where sensor conditioning and embedded processing must be integrated without a separate mixed-signal processor. Its 24 MHz M8C controller can manage configuration, acquisition sequencing, digital filtering, and data transfer, while the programmable mixed-signal resources provide implementation flexibility. The verified data does not identify ADC resolution, input count, sampling bandwidth, acquisition time, or DAC performance, making those details mandatory checks before an architecture decision. Validate input ranges, source impedance, sampling strategy, reference stability, and noise against the specific measurement class. Keep sensitive analog routing away from clock and high-current digital paths, and follow the manufacturer’s grounding and decoupling guidance. Production testing should include calibration data, gain verification, and repeatability across multiple programmed device configurations.

⚡

Motor and Actuator Control

The CY8C26643-24AI can be evaluated for compact actuator-control products that need deterministic embedded logic alongside configurable analog functions. The M8C core operates at up to 24 MHz, and its mixed-signal resources may assist with sensing, timing, or control-signal generation. The supplied information does not verify PWM resolution, timer count, capture functions, ADC performance, fault I/O, or operating-temperature limits, so it cannot by itself establish suitability for a safety-critical motor drive. A qualified design should compare those resources with the motor-control architecture, include independent overcurrent protection, and validate current loops and startup behavior under worst-case load. External drivers may also require level translation or isolation. Because PSoC configuration affects resource allocation, production firmware, test limits, and documentation must be frozen together to prevent configuration drift.

What are the key specifications of CY8C26643-24AI that engineers should know?
The CY8C26643-24AI is an 8-bit M8C PSoC 1 mixed-signal microcontroller rated for up to 24 MHz with 16 KB of flash memory in a 44-pin, 10 x 10 mm TQFP package. DigiKey identifies it as a CY8C26xxx device with 16K x 8-bit flash, while the supplied product data also identifies a 3.3 V operating supply. Its configurable mixed-signal architecture and PSoC Designer ecosystem are important requirements for firmware and PCB qualification.
What is the operating voltage of CY8C26643-24AI?
The supplied technical listings identify CY8C26643-24AI as a 3.3 V device. The verified material does not provide the complete minimum-to-maximum supply-voltage range, I/O voltage limits, or absolute maximum ratings. Before schematic approval, consult the manufacturer datasheet and confirm operating voltage, tolerance, decoupling requirements, and signal-level compatibility across every connected peripheral.
Where can I download the CY8C26643-24AI datasheet PDF?
A CY8C26643-24AI datasheet landing page is available through the supplied AllDataSheet source at https://www.alldatasheet.com/datasheet-pdf/pdf/82742/CYPRESS/CY8C26643-24AI.html. The provided search data does not contain a manufacturer-hosted PDF URL or an authentic document number, so the official Cypress or Infineon documentation archive should be checked before controlled engineering release.
Where can I find the CY8C26643-24AI pinout and package information?
The verified package information identifies CY8C26643-24AI as a 44-pin TQFP measuring 10 x 10 mm. A complete, pin-by-pin public pinout was not included in the supplied data, and assigning function names without the exact datasheet could cause routing errors. Use the manufacturer pin table and land pattern for all 44 pins, including power, ground, programming, reset, clock, analog, and GPIO assignments.

What can replace CY8C26643-24AI as a drop-in replacement?
No verified drop-in replacement for CY8C26643-24AI was established by the supplied cross-reference results. The search returned generic cross-reference tools and CY8C26643 family pages but no candidate confirmed as the same 44-pin TQFP footprint, pin-to-pin compatible, electrically equivalent, and software-compatible. Do not substitute a microcontroller based only on CPU speed, flash size, or package similarity; verify every pin, interrupt, analog resource, memory map, and programming requirement.
Is CY8C26643-24AI the same as CY8C26643?
CY8C26643-24AI is an orderable device designation associated with the CY8C26643 family, but the supplied data does not establish that the base family name is interchangeable on every package or configuration. The -24AI ordering code encodes specific package and qualification attributes that must be compared against the manufacturer ordering guide. Confirm the exact temperature, package, speed, and qualification fields before treating it as a substitution.
Is CY8C26643-24AI suitable for mixed-signal embedded control?
The CY8C26643-24AI is specifically identified as a PSoC 1 mixed-signal array with an onboard controller, so it is suitable for embedded designs combining an 8-bit M8C controller with configurable signal-processing resources.

Those detailed ratings were not present in the supplied verification data and must be checked in the manufacturer datasheet.
What is PSoC Designer compatibility for CY8C26643-24AI?
The supplied datasheet descriptions associate CY8C26643-24AI with PSoC Designer and PSoC silicon. Because it uses a configurable mixed-signal architecture, device support and configuration files are part of the design, not optional documentation. Engineers should confirm the supported PSoC Designer release, device database, programming cable, bootloader method, and production configuration workflow before committing the firmware toolchain.
CY8C26643-24AI vs CY8C26643-24PXI: which one fits the existing PCB?
The provided material does not verify CY8C26643-24PXI as a drop-in alternative or provide its complete ordering-code differences. A valid PCB decision requires comparison of package dimensions, pin numbers, electrical ratings, temperature range, qualification, and orderable part status. Keep CY8C26643-24AI for the exact approved configuration unless the manufacturer ordering guide and package drawing confirm equivalence.
When should I choose CY8C26643-24AI over a conventional 8-bit MCU?
Choose CY8C26643-24AI when a design benefits from an integrated 8-bit controller and configurable mixed-signal resources within the PSoC 1 ecosystem. The architecture may simplify peripherals that would otherwise require several discrete devices, but it also creates toolchain and configuration dependencies. A conventional MCU is preferable when the application needs a mature direct programmer ecosystem, broader off-the-shelf tooling, or application-specific features documented in a current production datasheet.
What design information is missing for a CY8C26643-24AI schematic?
The supplied data establishes the 8-bit architecture, 24 MHz clock, 16 KB flash, 3.3 V designation, and 44-pin TQFP package, but it does not include a complete pin table, SRAM capacity, GPIO assignments, analog ratings, or absolute maximum limits. Those values must be taken from the manufacturer datasheet before assigning nets or selecting passives. The 150-page mirror listing was not treated as proof of exact page-specific ratings.
Is CY8C26643-24AI compliant with RoHS, REACH, or automotive qualification?
The provided data does not verify RoHS, REACH, halogen-free, conflict-minerals, or AEC-Q100 status for CY8C26643-24AI. Compliance and qualification must be taken from the current manufacturer declaration or product documentation rather than inferred from the -AI ordering suffix. Do not release the part into a regulated or automotive design until the applicable material declaration and qualification records are obtained.

Справочные инженерные данные для CY8C26643-24AI — сравнение, рекомендации по проектированию и информация о соответствии.

Руководство по выбору

Choose CY8C26643-24AI when the design specifically benefits from the PSoC 1 configurable mixed-signal architecture, an 8-bit M8C controller, 24 MHz operation, 16 KB flash, and a 44-pin TQFP package. It is especially relevant when analog conditioning, programmable logic, and embedded control can share one device and the team can support PSoC Designer configuration and programming tools. Do not choose it merely for nominal CPU speed or flash capacity: verify the unavailable pin map, SRAM, analog ratings, peripherals, temperature range, and qualification data before schematic release. A conventional 8-bit MCU may be easier when off-the-shelf compiler support and fixed peripherals matter more than configurability. An STM32-class MCU should be considered only as a redesign because its core, memory architecture, peripherals, package, and software ecosystem differ. No verified drop-in replacement was found, so supplier continuity currently depends on sourcing the exact orderable device rather than substituting an electrically similar part.

Ключевые отличия

  • Configurable mixed-signal integration (против ATMEGA8A-AUR)
  • 24 MHz defined operating point (против STM32F072C8T6TR)
  • 16 KB integrated flash configuration (против ATMEGA8A-AUR)
  • Compact 10 x 10 mm TQFP integration (против STM32F030F4P6TR)

Заметки по проектированию

Do not substitute a microcontroller based only on the shared 44-pin TQFP designation. The supplied sources did not verify any pin-compatible alternative, and a PSoC replacement can differ in analog pin multiplexing, programming signals, interrupt vectors, memory organization, and peripheral resources. Compare the complete ordering guide, pin table, electrical limits, package drawing, and programming workflow before approving a second source.

Confirm the exact 44-pin TQFP land pattern and pin-1 orientation from the manufacturer package drawing before PCB release. The verified data establishes a 10 x 10 mm package but not the pad dimensions, courtyard, or pin numbering. Preserve access to programming and debug signals and follow the controller and analog grounding recommendations in the datasheet. Do not infer unused pins may be shorted, floated, or tied to any supply without checking their defined function.

Design the board around the verified 3.3 V device designation, but obtain the complete supply range, I/O thresholds, absolute maximum ratings, and power-consumption data before finalizing regulators and level shifters. Place required bulk and bypass capacitors at the locations prescribed by the manufacturer reference design. Validate sequencing, startup, reset behavior, and noise margins because undocumented voltage assumptions can create intermittent field failures.

Treat analog and digital resources as a configurable system rather than independent fixed peripherals. Freeze the PSoC configuration after assigning clocks, routing, interrupts, and analog blocks, then test that exact production image. Keep sensitive analog inputs away from clock and switching nodes, use short return paths, and verify whether external filtering or shielding is required. Because converter and analog ratings were not supplied, do not finalize gain, bandwidth, or accuracy calculations from assumptions.
