The device operates from a 3.3 V supply and is packaged as a 56-VFQFN with an exposed pad. Its architecture combines USB connectivity, an enhanced 8051 microprocessor, and programmable GPIO in one controller IC. An EZ-USB FX2LP is a highly integrated USB 2.0 controller in the broader semiconductor and embedded-controller hierarchy. It is designed for low-power USB peripheral applications requiring high-speed data transfer, flexible endpoint control, and firmware-based protocol implementation. Unlike a simple USB interface adapter, the smart SIE can handle low-level USB transactions while the embedded processor manages device-specific behavior, data movement, and host communication. The verified product information identifies the CY7C68015A-56LFXC as a ROMless 8051 EZ-USB FX2LP USB microcontroller in a 56-VFQFN exposed-pad package. It supports USB 2.0 high-speed operation and includes a single-chip USB 2.0 transceiver, smart SIE, and enhanced 8051 microprocessor. The low-power FX2LP positioning is especially relevant to battery-powered and portable equipment where USB connectivity must coexist with constrained power budgets. The integrated architecture reduces the component count required for a USB peripheral design by combining protocol handling, control logic, and general-purpose processing. Programmable GPIOs can support control signals, indicators, and external interfaces, while the ROMless architecture allows the application firmware to be loaded according to the product's programming and boot architecture. Exact RAM, GPIO, clock, endpoint, and electrical limits must be confirmed in the current manufacturer datasheet before schematic release. Typical applications include USB-to-serial adapters, data acquisition equipment, test and measurement instruments, industrial peripheral interfaces, storage and communication adapters, and portable USB-connected products. The device is particularly useful where a host bus requires protocol-specific buffering or endpoint handling beyond a basic UART or SPI USB bridge. A critical design consideration is package and pinout verification. The supplied search results confirm the 56-VFQFN exposed-pad package but do not provide the complete numbered pin list, so the design must be checked against the manufacturer datasheet land pattern, exposed-pad connection, decoupling requirements, and signal-routing guidance before fabrication. This page consolidates verified distributor and manufacturer-listing information, same-package family alternatives, comparison fields, and practical design cautions. It separates confirmed facts from unavailable specifications so engineers can identify what still requires validation from the manufacturer datasheet.

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.

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.

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.

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

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.

Typical uses include compact industrial control, sensor conditioning, keypad interfaces, simple actuator controllers, and embedded products where a small flash footprint and 20-pin DIP package simplify prototyping or legacy board maintenance. The device's through-hole format is particularly useful when a controller must be inserted or replaced without a fine-pitch surface-mount assembly. Designers should verify supply voltage, I/O limits, clock configuration, reset behavior, and available peripheral resources against the official datasheet before substitution. The 2 KB Flash capacity also makes firmware sizing and boot behavior important constraints; application code must fit within the available program memory after accounting for required startup and configuration routines. This page combines verified distributor metadata, package and memory information, application context, and sourcing guidance. It does not infer unreported electrical limits or claim a drop-in replacement unless the manufacturer or distributor data explicitly establishes package and pin compatibility.

CY8C24094-24AXI

CY8C24094-24AXI - 8-Bit 24MHz PSoC MCU, 16KB Flash | 100-VFBGA

The Infineon Technologies (formerly Cypress Semiconductor) CY8C24094-24AXI is a PSoC 1 programmable system-on-chip microcontroller built on the M8C 8-bit Harvard-architecture processor, operating up to 24 MHz with 16 KB (16K x 8) of embedded flash memory, and housed in a 100-ball VFBGA (6 x 6 mm) surface-mount package. A PSoC, or Programmable System-on-Chip, is an MCU architecture in which configurable analog and digital peripheral blocks are connected by a programmable interconnect array instead of being hard-wired to fixed pins. This lets one silicon device replace what would otherwise be an MCU, a timer, an ADC, an LCD drive stage and several discrete analog components on a mixed-signal control board. PSoC sits in the embedded microcontroller hierarchy alongside 8-bit and 32-bit MCUs, and is one member of the Cypress/Infineon PSoC 1 family. Key characteristics of this device include an M8C processor core rated to 24 MHz, 16 KB of flash program memory, and an on-chip XRES pin supporting In-System Serial Programming (ISSP) and external reset control. The family members differ mainly in the amount of configurable analog and digital resource they integrate, so designers can size the peripheral set to the board rather than to a fixed pin map. Technically, the M8C core uses a Harvard architecture with separate instruction and data spaces, a 16-bit instruction word, and an efficient sleep and watchdog management scheme suited to battery and handheld designs. The 100-VFBGA package keeps the footprint small for space-constrained industrial control, metering and IoT sensor designs, and its ball pitch supports fine PCB routing in dense analog/digital boards. Typical applications for this device include industrial control panels, energy metering and utility-side sensing, motor and actuator control, smart building and IoT sensor nodes, security and access peripherals, and consumer low-power key-scan and small motor products. Design consideration: PSoC 1 devices are programmed through the legacy ISSP interface rather than SWD or JTAG, so your toolchain, programmer and ISP header layout must be planned before the PCB is frozen. Confirm the ball map and exposed-pad connection directly in the manufacturer datasheet. This page brings together manufacturer and distributor specifications for the CY8C24094-24AXI, pin-compatible PSoC 1 alternatives, side-by-side parameter comparison, and practical layout and programming guidance that the bare datasheet does not summarize in one place.

Typical engineering use cases include small sensor-conditioning systems, simple control panels, keypad interfaces, low-speed communication modules, and educational embedded-control platforms. For a sensor interface, the MCU can execute acquisition-control logic and coordinate signal processing, although the supplied source does not verify a specific ADC resolution or sampling rate. For a control panel, the M8C core can manage discrete inputs and outputs, while the PSoC resources may reduce external circuitry when their electrical limits and configuration options are confirmed. Firmware compatibility, peripheral availability, and timing performance should be evaluated from the device documentation. The main design consideration is package and sourcing risk. A 28-DIP footprint is mechanically convenient but is not interchangeable with a surface-mount package without a PCB redesign. Before substituting any part, verify every pin, supply voltage, clock configuration, memory map, programming method, and peripheral function.

The verified distributor listing refers to the CY8C2442 I2C/SPI configuration, so the intended I2C or SPI requirement should be preserved when reviewing any substitution. Firmware, peripheral configuration, pin assignment, and timing behavior must also be checked before changing the MCU. Typical design uses include industrial control, sensor-interface equipment, small automation controllers, communication modules, and legacy embedded products. The 24 MHz clock provides processing headroom for control loops and peripheral services, while 4 KB flash limits firmware capacity to compact applications. The 256-byte SRAM is suitable for modest working memory, but developers should avoid relying on it for large buffers or complex protocol stacks. The most important design consideration is package and firmware compatibility. CY8C24423A-24PXI uses a 28-pin PDIP package, and the PSoC 1 device configuration affects pin multiplexing, clocking, interrupts, and peripheral behavior. Review the manufacturer datasheet for the exact pin assignments, electrical limits, programming procedure, and application-specific peripheral settings before production release. This page combines verified distributor specifications, sourcing information, and design guidance rather than inferring unprovided electrical details.
