A USB 2.0 peripheral controller is a specialized microcontroller that communicates with a USB host while exposing programmable data-transfer functions to the surrounding equipment. Its position in the hierarchy is USB interface controller → application-specific microcontroller → integrated circuit → semiconductor. The EZ-USB FX2LP architecture combines an 8-bit data-bus interface with dedicated USB control hardware, allowing portable peripherals, test equipment, and data-acquisition products to transfer data without implementing a complete USB host stack. The controller operates from 3 V to 3.6 V and uses a 24 MHz clock. The manufacturer describes 16K of embedded RAM, 24 GPIOs, and an integrated USB 2.0 transceiver. The 56-pin QFN construction supports compact PCB layouts, while the integrated transceiver avoids the additional area required by a separate USB transceiver. The architecture supports transfer rates exceeding 53 MB per second while using the maximum USB 2.0 bandwidth. The 8051-compatible core provides a familiar firmware platform, while the USB Serial Interface Engine handles low-level protocol functions and the controller’s parallel data path connects it to external data sources. Firmware can configure endpoint behavior, packet handling, and data movement between USB and the external 8-bit bus. This division of responsibilities allows a product to present a specialized USB peripheral function while reusing relatively simple external data-acquisition or buffering hardware. Typical uses include portable logic analyzers, test-and-measurement adapters, data-acquisition equipment, industrial peripherals, and compact USB-to-custom-interface products. The low-power design is particularly relevant to non-battery-powered equipment where the integrated transceiver and 3 V to 3.6 V operating range simplify power architecture. The controller is also suitable for designs requiring high-speed sustained transfers rather than low-rate control-only communication. When laying out the PCB, place the USB connector, differential data traces, and decoupling capacitors close to the controller. USB differential routing requires matched geometry and a continuous reference plane. Firmware developers should also account for the controller’s internal USB handling and external 8-bit data interface rather than treating it as a conventional general-purpose 8051 design. This page combines the manufacturer’s key device specifications with package, sourcing, comparison, and implementation guidance. It also distinguishes genuine same-package drop-in candidates from components that may provide similar USB functionality but require a different footprint, firmware strategy, or PCB redesign.

Endpoint configuration, descriptor handling, and data-transfer routines are implemented in firmware, allowing product behavior to be adapted without changing the external USB interface hardware. Exact endpoint-buffer capacity and all detailed electrical characteristics should be confirmed in the manufacturer datasheet for the final production design. Typical applications include USB-to-serial adapters, data-acquisition front ends, logic analyzers, oscilloscope interfaces, industrial control panels, test equipment, and portable instruments. The exposed-pad package supports compact surface-mount layouts, while the 3 V to 3.6 V operating range fits designs powered from regulated battery or USB-derived rails. PCB designers should follow the manufacturer pin-description table when assigning the exposed pad, supply pins, and ground connections. Place high-frequency decoupling capacitors close to the device, preserve the recommended USB data-routing geometry, and confirm that the PCB footprint and paste pattern match the 56-VFQFN package used by the selected ordering code. This page combines the manufacturer device description with family-level alternatives, package comparisons, sourcing guidance, and practical integration considerations. It is intended to help engineers determine whether the CY7C68015A-56LTXC fits a USB peripheral design before beginning firmware and PCB implementation.

CY7C68016A-56LFXC

CY7C68016A-56LFXC - USB 2.0 FX2LP Microcontroller | Infineon

Infineon Technologies CY7C68016A-56LFXC is a low-power EZ-USB FX2LP USB 2.0 microcontroller with an integrated high-speed transceiver, smart Serial Interface Engine, enhanced 8051 processor, 3.3 V operating supply, and 56-pin VFQFN exposed-pad package. It is designed for USB high-speed peripheral applications requiring flexible data transfer and compact board space. An EZ-USB FX2LP microcontroller is an application-specific USB controller in the broader hierarchy of 8051 microcontrollers, embedded processors, and USB interface integrated circuits. It combines a USB 2.0-compatible transceiver and serial-interface engine with an internal enhanced 8051 core. This integration allows one device to manage endpoint buffering, USB transfers, and peripheral data movement without relying on a separate USB transceiver. Verified listings identify the CY7C68016A-56LFXC as a ROMless 8-bit EZ-USB FX2LP device with USB, I2C, and USART interfaces. Its operating supply range is 3 V to 3.6 V, and its listed operating temperature range is 0 °C to 70 °C. The USB 2.0 implementation is USB-IF high-speed certified under TID 40440111. Its SMD package is a 56-pin VFQFN with an exposed pad and is supplied in a tube according to the verified distributor data. The controller’s integrated architecture reduces USB-interface component count by combining the transceiver, smart SIE, and enhanced 8051 processor in one package. Firmware controls endpoint configuration and data transfer behavior, while the processor handles application-specific processing. Because the device is ROMless, the design must provide a suitable firmware-programming and boot solution, and developers must budget memory appropriately for USB descriptors, endpoint logic, and application code. Typical uses include high-speed USB data acquisition, USB-to-serial and USB-to-parallel adapters, test and measurement equipment, data-logging systems, industrial peripherals, and consumer USB accessories. The 56-VFQFN exposed-pad package also requires careful PCB layout and thermal management so heat can transfer through its exposed pad while preserving high-speed USB signal integrity. A primary design consideration is the 3.0 V to 3.6 V supply constraint: the part cannot be connected directly to a 5 V USB VBUS rail without an appropriately designed power path. Layout should follow the manufacturer’s pin, differential-routing, decoupling, and exposed-pad guidance, while production firmware and connector behavior should be validated against the complete USB design. This page consolidates verified distributor specifications, package information, lifecycle-oriented cross-reference results, and practical replacement guidance that is not presented as a single-source manufacturer summary. It also distinguishes true same-footprint drop-in candidates from broader USB-controller alternatives that require firmware or hardware changes.

It combines a high-speed USB device controller with programmable peripheral logic, making it suitable for USB-to-serial, USB-to-parallel, data acquisition, instrumentation, and industrial interface adapters. The device supports full-speed and high-speed USB operation according to its published product classification. An EZ-USB FX2LP controller is an application-specific USB microcontroller rather than a general-purpose MCU. Its internal 8051-compatible processing engine, USB interface, and programmable I/O architecture allow a single device to implement peripheral functions directly in USB firmware. In the broader hierarchy, the part is a USB interface controller, interface IC, embedded microcontroller, and semiconductor used to bridge USB connectivity with external data acquisition, control, or communication circuitry. The CY7C68016A-56LTXC combines a 24 MHz operating clock with a 3 V to 3.6 V supply range and 40 I/O ports. Its ROMless architecture directs firmware into external memory, allowing application-specific code to define enumeration, data transfer protocols, and peripheral behavior. USB 2.0 high-speed support provides a practical bandwidth advantage over full-speed-only designs when the host, cable, firmware, and peripheral implementation support the required transfer rate. The exposed-pad 56-VFQFN package supports compact surface-mount layouts while providing a thermal and electrical connection to the PCB through its exposed pad. The 56-pin arrangement supports the USB signals, 8051 core functions, external program and data memory interfaces, general-purpose I/O, clock, reset, and power connections. Because this is a ROMless embedded controller, designers must also provide the required external memory and ensure firmware timing, memory addressing, and USB endpoint configuration are compatible with the target system. Typical applications include high-speed USB test equipment, oscilloscope and logic-analyzer interfaces, industrial measurement modules, USB-to-serial bridges, data loggers, scanners, laboratory instruments, and embedded host adapters. The 40 available I/O ports are especially useful when an application requires multiple discrete controls, status indicators, data buses, or peripheral select signals in addition to the USB interface. PCB implementation should follow the Infineon pin and layout guidance for the 56-VFQFN exposed-pad package. Keep USB differential routing short, impedance controlled, and continuous, and provide the specified input and bypass capacitors near their associated pins. Route high-speed or sensitive signals away from the exposed pad connection where practical, and make adequate provision for thermal dissipation through the package pad and surrounding copper. This product page combines the exact published device characteristics, application-oriented guidance, comparison criteria, and practical design notes needed to evaluate the CY7C68016A-56LTXC. Review the complete pin description, electrical limits, memory interface, USB timing, and exposed-pad layout instructions in the manufacturer datasheet before schematic sign-off or PCB release.

The supplied product description identifies a 1.8 V low-voltage implementation, 24 GPIOs, and a 56-ball VFBGA. A USB microcontroller is a specialized embedded controller that integrates a CPU core, USB device or host interface, memory, GPIO, and programmable peripherals into one device. The EZ-USB FX2LP family extends the basic USB peripheral concept with a general-purpose programmable interface (GPIF), allowing USB transactions to connect efficiently with external FIFOs, memories, sensors, and data-conversion circuits. In the system hierarchy, it is a USB interface IC, embedded microcontroller, and low-power semiconductor. Key verified features include USB 2.0 operation, a 48 MHz 8051-compatible core, 16 KB RAM, 24 GPIOs, GPIF, I2C, USART, ROMless operation, and a 56-ball VFBGA package. The low 1.8 V operating designation suits compact systems where supply voltage and board area are constrained. Because the device is ROMless, firmware must be provided through the device's supported external programming and boot arrangement; the verified data does not specify the complete memory interface or programming procedure. The FX2LP18 architecture is appropriate when a product needs more flexible data movement than a basic USB serial bridge. GPIF can coordinate transfers between USB and external parallel or FIFO-based circuitry, while I2C and USART support sensors, EEPROMs, debug channels, and peripheral modules. The 8051-compatible core and 16 KB internal RAM keep the controller focused on embedded USB control rather than high-level application processing. Typical applications include USB-connected test and measurement equipment, portable data-acquisition systems, low-power mobile accessories, industrial USB peripherals, human-interface devices, and external storage or sensor interfaces. Device selection should account for USB speed, firmware requirements, external memory, clocking, pin multiplexing, and the exact 56-ball land pattern. The principal design consideration is PCB implementation. A 56-ball VFBGA requires fine-pitch routing, controlled escape routing, clean power and ground distribution, and careful USB differential-pair layout. Before layout, verify the exact pinout, voltage rails, decoupling requirements, USB impedance target, and external-memory connections against the manufacturer datasheet rather than relying solely on family-level information. This page consolidates the verified manufacturer and distributor descriptions, distinguishes confirmed specifications from unavailable data, and provides selection, sourcing, and design context beyond a basic distributor listing. Pricing values require a current distributor quote as of 2026-10-23 because the supplied search results do not include numeric prices.

The device combines capacitive touch detection with general-purpose I/O functions for buttons, LEDs, and interrupt signals, making it suitable for compact human-interface control boards. A capacitive controller is a semiconductor that detects changes in capacitance caused by a conductive object approaching or touching a sensor electrode. CapSense Express controllers belong to the capacitive-sensing controller hierarchy, where programmable I/Os, sensing electrodes, and application-specific control logic are integrated into a single device. This reduces the number of discrete components required for keys, sliders, lighting, and interface signaling. The verified product information identifies 10 configurable I/Os. These can support one capacitive sensing slider with 10 segments, while the remaining I/Os can operate as buttons or GPIOs for functions such as driving LEDs or producing interrupt signals based on button conditions. The available documentation also associates the family with configurable touch-button and touch-interface functions. The CY8C20121-SX1I is identified as an industrial-temperature variant in the part-number documentation. Its 8-pin SOIC format supports conventional surface-mount PCB assembly and is appropriate for compact control modules where component height and routing simplicity matter. Because the verified excerpts do not provide operating voltage, flash size, clock rate, or electrical timing values, those parameters remain subject to the manufacturer datasheet and device characterization. Typical uses include consumer touch controls, appliance interfaces, industrial panels, access controls, compact keypads, and LED-feedback touch buttons. In a slider design, the controller evaluates the distributed capacitance among sensor segments and reports the selected position through its configurable interface. In a button design, the same device can combine touch detection with direct GPIO behavior and conditional interrupt signaling. Designers should confirm the exact pin assignments, sensor configuration method, supported operating voltage, and firmware requirements before layout release. A two-layer implementation should preserve short sensor traces, provide an unobstructed sensor-to-electrode connection, and follow the grounding and reference layout specified by the manufacturer datasheet. The package's exposed functions should also be checked against the intended button, slider, LED, and interrupt allocation. This product page consolidates verified distributor pricing, package information, configuration capabilities, and practical design considerations. It also separates documented facts from unavailable electrical details and avoids presenting unverified drop-in equivalents as guaranteed replacements.

CY8C20132-LQXI

CY8C20132-LQXI - CapSense Express Microcontroller | Infineon Technologies

Infineon Technologies CY8C20132-LQXI is a CapSense Express embedded microcontroller in a 24-QFN package. The verified distributor listings identify the device as a microcontroller IC, while application-specific details such as program memory, RAM, I/O count, clocking, and electrical ratings were not included in the supplied source records. Its CapSense Express designation places it in the capacitive-sensing and embedded-control market, where the device is intended to combine touch sensing, control logic, and embedded processing in one integrated component. The exact electrical and functional characteristics should therefore be confirmed in the manufacturer datasheet before schematic capture, firmware development, or production release. What is a CapSense Express microcontroller? It is an embedded microcontroller category designed to support capacitive-touch user interfaces together with digital control functions. In the broader hierarchy, a microcontroller is a programmable semiconductor containing a processor core, memory, peripherals, and I/O; a CapSense device adds touch-sensing capabilities intended for buttons, sliders, trackpads, and similar interfaces. This makes the part relevant to human-interface and control designs where touch sensing and embedded logic are consolidated rather than implemented as separate components. The most reliable package information available from the supplied results is 24-QFN. The exact body dimensions, pin assignments, exposed-pad arrangement, and recommended land pattern were not provided, so those values remain datasheet-dependent. The verified sources identify Infineon Technologies and Cypress Semiconductor Corp. in different distributor records, reflecting the product’s manufacturer and legacy branding history. Firmware compatibility, peripheral availability, memory size, and lifecycle status should be checked against the current manufacturer documentation. Typical design uses include capacitive touch controls, human-interface modules, industrial panels, consumer controls, and embedded products requiring a compact sensing-and-control solution. The part should not be selected solely from the distributor category label; engineers should verify the required touch channels, scan method, ADC or comparator resources, communication peripherals, memory, and GPIO count in the datasheet. Those missing parameters are especially important when replacing an existing Cypress or PSoC-family design. For robust implementation, preserve the manufacturer-recommended decoupling, exposed-pad thermal layout, and pin-specific routing guidance. Confirm the exact suffix interpretation before ordering, because the LQXI package and ordering code may encode qualification, temperature, and production options that are not visible in the supplied search results.

CY8C20140-SX21 - CapSense Express Touch Controller | Cypress

The Cypress Semiconductor CY8C20140-SX21 is a CapSense Express-10 configurable I/O controller for capacitive touch buttons and sliders, packaged in a surface-mount SOIC-16 package. The device supports up to 10 configurable I/O channels that can be assigned to capacitive sensing buttons, a 10-segment slider, general-purpose I/O, LED driving, or interrupt signaling according to the verified manufacturer and distributor descriptions. Its capacitive-sensing architecture is intended to replace mechanical switches in compact consumer, industrial, and appliance interfaces. A capacitive touch controller is a specialized semiconductor that detects changes in capacitance caused by a user's finger or conductive object. The CY8C20140-SX21 belongs to the CapSense Express family, a configurable touch-control and GPIO platform within the broader microcontroller and human-interface IC category. Compared with mechanical switches, capacitive sensing supports sealed panels, flexible control surfaces, LED feedback, and programmable button behavior without exposing moving contacts to dust, moisture, or wear. The verified data identifies support for four to ten capacitive sensing buttons, one configurable 10-segment capacitive slider, and additional I/O resources for LEDs or interrupt outputs. Configuration is performed through an I2C interface, and operating parameters can be stored in onboard nonvolatile memory so that the controller can load its configuration automatically at power-on. This combination supports both development flexibility and production designs requiring deterministic startup behavior. The CY8C20140-SX21 is particularly useful when a product needs a small number of touch inputs without using a general-purpose MCU. A slider can provide directional or level control, while remaining channels can serve as buttons or GPIOs. The verified sources identify the controller as a CapSense Express-10 device and describe configurable I/O behavior, but they do not provide a complete electrical limit table, recommended capacitor values, temperature range, or detailed timing characteristics. Typical applications include appliance control panels, consumer-electronics keypads, compact industrial interfaces, and embedded products that combine capacitive buttons with LED indication. The controller can be placed beside a PCB-mounted or panel-mounted sensor electrode and connected to a host controller through I2C. Designers should verify the complete datasheet electrical characteristics, electrode configuration, power sequencing, and firmware configuration method before finalizing a new PCB. This page distinguishes verified product facts from unavailable detailed parameters, links the original manufacturer and distributor references, and provides application guidance, comparison parameters, and replacement considerations for engineers evaluating the CY8C20140-SX21. Detailed values not present in the supplied sources are explicitly marked as unavailable rather than inferred.

CY8C20180-SX21 - CapSense Touch Controller | Infineon
CY8C20180-SX21

CY8C20180-SX21 - CapSense Touch Controller | Infineon

Infineon CY8C20180-SX21 is a CapSense Express-Button capacitive-touch controller with configurable I/O, packaged as a 16-pin SOIC. The device is intended for compact user-interface designs that detect finger touches through capacitive sensors rather than conventional mechanical pushbuttons. Its capacitive-sensing role places it within the broader hierarchy of capacitive-touch controller, programmable I/O controller, embedded microcontroller, and integrated semiconductor. The verified distributor listing identifies the CY8C20180 family as a configurable-I/O capacitive-button controller and provides a starting price of $0.1171 as of 2026-10-28. A capacitive-touch controller detects changes in capacitance associated with a conductive sensor electrode. The Cypress datasheet search results describe the CY8C20180 as a CapSense Express-Button device with configurable I/Os, allowing a design to combine touch detection with control or signaling functions in a small package. This makes the controller suitable for appliance controls, access panels, compact keypads, and other products where mechanical switches would consume space or create wear concerns. The most important documented feature of this family is its configurable I/O architecture. Configurable I/O can simplify interface allocation when a board needs both touch sensing and conventional digital functions, reducing the number of separate devices when the controller can handle compatible signals. The verified distributor information also confirms the SO16 package format for the closely identified family member, while the target suffix-specific pin map, electrical limits, and programming details must be confirmed in the manufacturer datasheet before layout or firmware commitments. Technically, the device belongs to the CapSense family of touch-sensing controllers rather than the general-purpose MCU class. This distinction matters because firmware, sensor tuning, and application development are centered on capacitive scanning and button behavior. Search results identify the family as CY8C20180, but they do not establish the target part's complete timing, flash, memory, clock, or environmental limits. Those values must not be inferred from similarly named devices; engineers should use the exact CY8C20180-SX21 documentation for production design decisions. Typical use cases include touch-sensitive kitchen appliances, room controls, wearable interfaces, and access-control panels. In an appliance, the controller can replace a conventional button and interpret capacitive electrode events while providing configurable digital connections to surrounding logic. In a compact keypad, multiple touch positions can be mapped to product functions, provided the sensor geometry, grounding, shielding, and firmware configuration are validated for the intended environment. The primary design consideration is to treat analog sensor layout as part of the controller design rather than as an afterthought. Keep capacitive traces short where practical, maintain the documented sensor construction, provide suitable ground and shielding, and validate noise immunity with the final enclosure and cables. Firmware should also include debouncing and environmental compensation because humidity, nearby conductors, and power-supply variation can influence capacitive measurements. This page consolidates the verified distributor availability, product identity, package information, and cross-reference findings for CY8C20180-SX21. It also separates documented facts from unavailable electrical data, provides practical application guidance, and explicitly identifies the lack of verified pin-compatible alternatives rather than presenting unverified substitutions as drop-in choices.

CY8C201A0-SX21 - CapSense Express Slider | Cypress
CY8C201A0-SX21

CY8C201A0-SX21 - CapSense Express Slider | Cypress

The Cypress Semiconductor CY8C201A0-SX21 is a CapSense Express configurable capacitive-touch controller with 10 configurable IOs, slider support, and an I2C interface. The device can assign its IOs to capacitive sensing buttons or general-purpose functions such as driving LEDs or generating interrupts. It is supplied in the manufacturer ordering code CY8C201A0-SX21, with the package and electrical operating limits documented in the CY8C201A0 family datasheet. A capacitive-touch controller is a specialized mixed-signal semiconductor that measures changes in capacitance caused by a user's finger or conductive object. The CapSense Express family sits below touch-sensing subsystems in the product hierarchy, while its configurable architecture allows a limited number of sensing and GPIO operations to be consolidated into a compact controller. This approach is useful when a product needs a small keypad, slider, proximity interface, or combination of touch inputs and indicator outputs. The primary verified feature set includes 10 configurable IOs, support for capacitive buttons, GPIO operation for LEDs or interrupts, slider capability, and I2C connectivity. Consolidating these functions can reduce the number of separate discrete input devices and controller components required for a human-interface panel. The I2C interface also provides a practical path for configuration, status reading, and host-controlled firmware behavior in embedded products. The verified manufacturer datasheet information identifies the CY8C201A0 as a CapSense Express slider capacitive controller. Its programmable I/O model supports mixed touch-sensing and digital-output use cases, allowing one device to participate in both user-input detection and interface feedback. The 12-page datasheet representation shown in the verified search results provides the principal source for family features, pinouts, electrical specifications, and the I2C interface. Typical uses include compact capacitive keypads, touch-sensitive sliders, LED-feedback control, industrial control panels, appliance interfaces, and embedded human-interface panels. In each case, the controller's 10 configurable IOs provide the principal resource constraint, while I2C provides communication with a host microcontroller. The correct button count, slider implementation, and GPIO assignment must be selected through the device configuration workflow rather than inferred solely from the order code. Designers should confirm the exact package dimensions, exposed-pad or lead configuration, pin mapping, operating voltage, logic levels, and recommended external sensor components against the manufacturer datasheet before layout. PCB copper for capacitive electrodes should follow the manufacturer's recommended sensor geometry and grounding guidance because trace length, shield spacing, and surrounding metal can change measured capacitance. Firmware must also validate debounce, sensitivity, and false-touch behavior in the final enclosure. This product record consolidates the verified distributor price, manufacturer-family feature description, datasheet references, and engineering selection guidance. It also clearly identifies unavailable voltage, current, package, and lifecycle details rather than estimating them, helping engineers separate confirmed CY8C201A0-SX21 facts from parameters that still require validation against the official documentation or internal component records.

CY8C22113-24PI - 8-Bit 24MHz 2KB Flash MCU | Infineon
CY8C22113-24PI

CY8C22113-24PI - 8-Bit 24MHz 2KB Flash MCU | Infineon

The Infineon CY8C22113-24PI is an 8-bit M8C-series embedded microcontroller rated at 24 MHz, with 2 KB of flash program memory, 256 bytes of data RAM, and an 8-pin PDIP package. It is designed for compact embedded-control tasks requiring modest processing throughput, nonvolatile firmware storage, and a low pin count. The device is identified as Cypress Semiconductor hardware and is currently distributed under the Infineon name. A microcontroller is a programmable semiconductor that integrates a CPU, memory, digital I/O, timers, and supporting peripherals on one device. The M8C architecture belongs to the embedded-controller hierarchy, which also includes 8-bit microprocessors, 16-bit and 32-bit microcontrollers, and application-specific processors. The CY8C22113-24PI sits at the entry level of that hierarchy: its 24 MHz clock and 2 KB flash capacity favor control-oriented logic rather than graphics, connectivity stacks, or data-intensive workloads. Verified source data identifies the device as an 8-bit MCU with 2 KB flash, a 24 MHz operating speed, 256 x 8 data RAM, and an 8-DIP package measuring 0.300 inches across a 7.62 mm lead span. These values make it potentially useful for simple keypads, status indicators, timers, sensor interfaces, and compact household or industrial controllers. The limited memory must be considered carefully before adopting complex firmware, buffering, or protocol stacks. The M8C family uses an 8-bit processing core intended to balance responsiveness with simple embedded-system economics. At 24 MHz, the device provides substantially more timing margin than basic low-speed control loops, while 2 KB of flash constrains program complexity. The exact operating voltage range, timer resources, digital I/O ratings, interrupt architecture, and clock options are not included in the supplied source snippets and therefore require confirmation from the manufacturer datasheet before design release. Typical implementation uses require assigning ports to switches, sensors, displays, or actuators, programming flash-resident firmware, and adding power, decoupling, reset, and interface components around the eight-pin device. Because only eight leads are available, port allocation and multiplexing are especially important. A conservative design should reserve enough pins for its power rails and essential interfaces, then verify every external signal against the complete datasheet pinout. The principal engineering trade-off is compactness versus expansion headroom. The 8-pin PDIP is useful for prototypes, through-hole production, and serviceable assemblies, but it provides fewer I/O options than larger microcontrollers. At 2 KB flash and 256 bytes of RAM, firmware should avoid libraries or buffering that consume substantial memory. Verify reset behavior, clock configuration, peripherals, electrical limits, and programming compatibility using the full manufacturer documentation. This page consolidates verified distributor and archival part information into an application-oriented guide. It distinguishes confirmed facts from unavailable technical data, highlights the memory and package constraints, and avoids treating general cross-reference tools as proof that an unrelated MCU is a true drop-in replacement. That distinction is important because pin-compatible hardware may still require different firmware, peripherals, voltage limits, or programming tools.

CY8C22113-24SI - 8-Bit 24MHz 2KB Flash MCU | Infineon

The Infineon Technologies CY8C22113-24SI is an 8-bit M8C PSoC 1 CY8C22xxx microcontroller operating at 24 MHz, with 2 KB of flash memory in an 8-pin SOIC package. It combines a programmable mixed-signal microcontroller core with embedded system resources in a compact surface-mount format suited to compact control, sensing, and embedded products. A microcontroller is a programmable semiconductor that integrates a CPU, memory, and peripheral functions onto one device. Within the broader embedded hierarchy, this device belongs to the 8-bit microcontroller class, the M8C PSoC 1 family, and the CY8C22xxx device family. Its mixed-signal architecture allows embedded control functions and analog-related resources to be evaluated for applications such as keypads, touch interfaces, sensor-conditioning systems, and compact consumer-control products. The verified product data identifies an M8C processor, 24 MHz operating frequency, and 2 KB, or 2K x 8 bits, of flash memory. The eight-pin SOIC package limits available external connectivity, so engineers should verify pin multiplexing, programming signals, power requirements, and application-specific analog functions in the manufacturer datasheet before finalizing a board design. The -24SI ordering code is presented exactly as supplied by the verified distributor listing. The 24 MHz clock gives the processor a higher operating-frequency headline than legacy 8-bit designs, while the 2 KB flash allocation favors compact control code rather than storage-intensive firmware. Firmware sizing, boot behavior, interrupt requirements, and peripheral configuration must therefore be checked early. A small package can reduce PCB area, but its restricted pin count also increases the importance of pin multiplexing and board-level signal planning. Typical design targets include compact touch controls, keypad scanners, low-cost embedded controllers, portable accessories, and small industrial or consumer interfaces. In these systems, the MCU can serve as the central controller, reading inputs, applying decision logic, and driving outputs. Its suitability depends on whether the available 2 KB of flash, eight pins, and documented mixed-signal resources meet the product requirements. For a new design, obtain the manufacturer datasheet and PSoC technical reference material, then verify the exact pinout, electrical limits, programming method, and peripheral availability. Do not assume that a functionally similar MCU is pin-compatible; replacement must be checked against both the package footprint and every connected signal. This page combines verified distributor facts with explicit data gaps where the supplied sources do not establish detailed electrical specifications.
