CY8C20142-SX1I - 4-IO CapSense Controller | Infineon
CY8C20142-SX1I

CY8C20142-SX1I - 4-IO CapSense Controller | Infineon

The Infineon Technologies CY8C20142-SX1I is a CAPSENSE Express capacitive-touch button controller with 2.4 V to 5.5 V operating supply, four configurable GPIOs, and an 8-pin SOIC package. It combines capacitive sensing for external touch buttons with general-purpose GPIO functions for LED indication, interrupts, and related mixed-signal control tasks. The controller operates from -40°C to 85°C and supports I2C communication. A capacitive-touch controller is an interface IC that detects changes in capacitance caused by a user's finger and converts those analog changes into digital events. In the product hierarchy, this device is a CAPSENSE Express controller within the broader class of capacitive sensing controllers, interface ICs, and mixed-signal semiconductors. Its purpose is to replace discrete analog sensing networks with a configurable digital interface suitable for compact user-interface designs. Key features include four configurable I/O channels that can be used as capacitive-sensing inputs or GPIOs, a 2.4 V to 5.5 V supply range, and I2C connectivity. One verified distributor listing identifies 2 kbits of device memory, while another describes 512 bytes of RAM and PWM capability. The SOIC-8 package provides a compact surface-mount footprint, and the -40°C to 85°C range supports industrial-temperature designs. The device combines a small embedded controller with configurable sensing and GPIO resources. Its four channels can be allocated according to the interface requirements of the product, while the I2C interface allows a host microcontroller or system controller to configure and monitor touch events. Because it is a dedicated CapSense Express controller rather than a general-purpose MCU, it can reduce the sensing burden placed on the primary embedded processor. Typical applications include appliance control panels, industrial touch buttons, equipment interfaces, consumer products, and low-cost human-machine interfaces. A connected host can read button states over I2C, update LED indicators through selected GPIOs, and respond to user input without dedicating a separate analog front end to capacitance measurement. PCB layout is critical for reliable capacitive sensing. The sensing electrodes, their connecting traces, ground structures, and enclosure materials influence sensitivity and stability. Designers should follow the manufacturer's pinout and application guidance, keep sensitive routes short, provide a stable ground reference, and evaluate the complete mechanical and electrical environment rather than treating the controller as a conventional digital switch input. This page consolidates the verified manufacturer and distributor information for CY8C20142-SX1I and adds package-specific design guidance, parameter comparisons, and a same-family replacement analysis. The alternative assessment is intentionally conservative: only controllers documented as using the same package are treated as potential drop-in parts, and unsupported electrical details are marked as data needed rather than estimated.

CY8C20160-SX2I

CY8C20160-SX2I CapSense Touch Controller | Infineon

The Infineon CY8C20160-SX2I is a CapSense Express capacitive-touch controller with 16-SOIC packaging and six configurable I/O resources for capacitive sensing or general-purpose output functions. The verified distributor data identifies it as a capacitive-touch button controller, while the product family supports configurable capacitive-sensing buttons and GPIOs for driving LEDs or generating interrupts. It is associated with a 3 V supply voltage and an operating-temperature range of -40°C to 85°C. A capacitive-touch controller is a semiconductor that detects changes in capacitance caused by a user touching an electrode or sensor pad. In the broader hierarchy, the CY8C20160-SX2I belongs to the family of capacitive-sensing controllers, touch-screen controllers, embedded controllers, and integrated circuits. Unlike a mechanical switch, this controller can interpret capacitive input electronically and combine that function with programmable digital I/O in a compact surface-mount device. The primary feature is the integration of CapSense Express control with six I/O resources. According to the verified technical listing, the I/O can be configured as capacitive-sensing buttons or as GPIOs for driving LEDs or interrupts. This combination reduces the number of separate components required for a small user-interface panel because touch detection and immediate digital-output functions can coexist in one controller. The 16-SOIC package also supports conventional surface-mount PCB assembly. The device operates from a 3 V supply and is specified over -40°C to 85°C. These values place it in an industrial-temperature operating range suitable for embedded controls, access panels, appliances, and compact human-interface systems. The verified listing also associates the part with a 2 kbit data density, while another distributor specification reports 2 KB of flash and 512 bytes of RAM. These memory descriptions should be confirmed against the applicable manufacturer documentation before relying on them for firmware sizing. Typical uses include capacitive buttons for appliance controls, illuminated touch keys, compact access panels, and LED or interrupt-driven user interfaces. Because the I/O resources can serve both sensing and GPIO roles, the controller is especially useful when a design needs a limited number of touch inputs without adding a larger general-purpose microcontroller. Designers should confirm the exact pin mapping, usable I/O count, memory organization, and programming requirements from the manufacturer datasheet before layout release. PCB design must preserve the intended capacitive-sensing electrode geometry, provide suitable grounding and filtering around the controller, and account for connector, copper, and enclosure effects that can change touch performance. This page consolidates the verified distributor specifications, package information, commercial availability, candidate family alternatives, and practical design cautions. It also separates confirmed values from specification gaps, helping engineers evaluate sourcing and fit without treating search-result snippets as a substitute for the complete manufacturer datasheet.

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.

The verified distributor data identifies the device as an 8 I/O CapSense Express controller and lists a 2 kbit density, eight pins, and a -40 °C to +85 °C operating-temperature range. A capacitive-touch controller is a type of interface IC that detects changes in electrical capacitance caused by a user touching an external sensor electrode. In a knowledge-graph hierarchy, the CY8C20180-SX2I belongs to the CapSense controller family, interface ICs, and semiconductor devices. Its four configurable I/O resources can be assigned to capacitive-sensing buttons or used as GPIOs for driving LEDs or interrupt functions, allowing a small control panel to replace mechanical switches. The key verified features are four configurable I/O channels, capacitive sensing of up to four buttons, 3 V operation, 2 kbit density, eight-pin SOIC packaging, and an extended -40 °C to +85 °C temperature range. The distributor listing also identifies the part as an Infineon capacitive-touch button controller. Exact pin names, device-programming details, current consumption, and electrical timing limits were not included in the supplied source data and therefore are not inferred here. The CY8C20180-SX2I is suitable for low-voltage embedded user interfaces where a dedicated touch controller simplifies front-panel design. Its small SOIC footprint helps preserve board area in compact products, while configurable I/O supports shared sensing and general-purpose control requirements. The I2C-related functionality mentioned in comparison data should be verified against the manufacturer datasheet before final firmware and PCB sign-off. Typical applications include appliance control panels, small consumer products, industrial interface modules, LED status indicators, and embedded keypad or button assemblies. For a new design, confirm the exact sensor geometry, electrode size, grounding, shielding, and firmware configuration using the manufacturer application guidance. The -40 °C to +85 °C range makes the part suitable for industrial-temperature indoor products when the surrounding enclosure and connector system are also qualified. A practical design consideration is to keep capacitive-sensing traces short and keep the touch electrode away from high-current switching nodes and noisy sources. The controller does not eliminate the need for careful analog layout, filtering, calibration, and environmental tuning. This page synthesizes verified distributor specifications, replacement research, package information, and practical integration guidance while clearly separating missing datasheet details from confirmed values.

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.

CY8C201A0-SX2I

CY8C201A0-SX2I - 10-I/O CapSense Controller | Infineon

The Infineon Technologies CY8C201A0-SX2I is a CapSense Express capacitive-touch controller with 10 configurable I/Os, one slider, 2 kbits of onboard nonvolatile configuration memory, and a 16-pin SOIC package. It is designed to operate from a 3 V supply and supports capacitive sensing buttons, sliders, LEDs, and general-purpose I/O functions in compact user-interface systems. A capacitive-touch controller is a type of interface IC that detects changes in capacitance caused by a user's finger and converts those changes into digital control events. The CY8C201A0 family belongs to the broader hierarchy of capacitive sensing controller, touch interface IC, interface IC, and semiconductor. Its slider capability is useful where a physical linear control is preferred over discrete buttons. The device supports 4 to 10 capacitive sensing CapSense buttons and can configure its I/O resources for sensing or GPIO use. The verified manufacturer-family datasheet describes configurations including one 10-segment slider or one 5-segment slider, with additional configurable I/O available for LEDs and interrupts. Configuration is handled through an I2C port and stored in onboard nonvolatile memory for automatic loading at power-on. Key verified characteristics include 10 configurable I/Os, 2 kbits of nonvolatile memory, a 3 V supply, a 16-pin SOIC package, and an operating temperature range of -40°C to +85°C. Search results also identify 1.5 mA supply current and 5 pF load capacitance for the compared 16-SOIC ordering variants, while the exact electrical limits for this MPN should be confirmed in the manufacturer datasheet. Typical uses include appliance control panels, compact touch-key interfaces, consumer products, industrial equipment, and embedded human-interface systems. The I2C control interface and stored configuration simplify firmware integration, while the small SOIC footprint supports conventional surface-mount assembly. Designers should verify the complete pin assignment and electrical limits in the manufacturer datasheet, especially because search results also expose an older 8-SOIC description that conflicts with the verified 16-SOIC distributor listing. PCB designs should preserve the documented I2C pull-up arrangement and provide appropriate grounding and sensor-layout practices for stable capacitive measurements. This page consolidates verified distributor listings, manufacturer-family datasheet information, a strict drop-in alternative review, application guidance, and practical design notes. It is intended to help engineers evaluate procurement, compatibility, and implementation requirements without relying on a single retail listing.

CY8C21345-24SXI - 24MHz PSoC 1 8-Bit MCU, 24 GPIO, 8KB Flash | Infineon
CY8C21345-24SXI

CY8C21345-24SXI - 24MHz PSoC 1 8-Bit MCU, 24 GPIO, 8KB Flash | Infineon

The Infineon Technologies CY8C21345-24SXI is a PSoC 1 programmable system-on-chip microcontroller with an M8C 8-bit Harvard-architecture core running up to 24 MHz, 8 KB of flash memory, 24 general-purpose I/O pins, a 10-bit successive-approximation ADC and dedicated LCD drive capability, all housed in a 28-pin SOIC (SOP-28) surface-mount package. A PSoC (Programmable System-on-Chip) is a mixed-signal microcontroller that integrates a CPU, configurable analog blocks, configurable digital blocks and dedicated routing into a single device, so analog front-end functions such as ADCs, comparators and amplifiers can be configured in silicon instead of being built from discrete components. In the taxonomy of semiconductors, the CY8C21345-24SXI is an 8-bit microcontroller, and within that class it belongs to the mixed-signal MCU / programmable system-on-chip family rather than to a general-purpose digital MCU. Key device characteristics include a 3 V to 5.25 V operating supply range, an industrial temperature grade, four programmable digital blocks, and an M8C core that provides an 8x multiply with 32-bit accumulate. The 24 GPIOs provide flexible routing between the digital blocks, analog blocks, LCD segment outputs and general-purpose pins, which is what allows small peripheral counts to be handled without external glue logic. The 10-bit SAR ADC supports typical sensor-signal conditioning tasks such as thermistor, potentiometer and bridge-based measurement. Architecturally, the Harvard-style M8C core separates instruction and data access, giving deterministic execution alongside the analog configuration capability of the PSoC fabric. Flash program memory is 8 KB (8K x 8), and the device is supplied in the 28-SOIC industrial package with a gull-wing lead form and rectangular body. This combination places the part squarely in the class of low-cost mixed-signal MCUs used for human-interface and control products. Typical applications include LCD instrument panels and utility meters, capacitive or resistive touch keypads, small battery-powered sensor nodes, industrial temperature controllers, and compact consumer metering products where a display, a keypad and a small number of analog inputs must all be served by one inexpensive microcontroller. When designing around this device, plan the analog and digital block configuration in PSoC Creator before layout, keep the LCD segment drive lines on dedicated pins, and confirm the flash budget early because 8 KB is the constraint most often hit when adding bootloader or logging features. Verify the SOIC-28 land pattern and pin assignment against the manufacturer datasheet before routing.

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

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.

CY8C22213-24LFI

CY8C22213-24LFI - 24MHz 8-Bit PSoC 1 MCU | Infineon

The Infineon Technologies CY8C22213-24LFI is an 8-bit M8C PSoC 1 mixed-signal microcontroller operating at 24 MHz with 2 KB of flash memory in a 32-QFN package measuring 5 x 5 mm. It combines a programmable embedded controller with configurable mixed-signal resources, allowing designers to consolidate analog control, digital logic, and microcontroller functions on a single device. A PSoC, or Programmable System-on-Chip, is a mixed-signal microcontroller family that integrates an MCU core with configurable analog and digital blocks. The M8C core handles control-flow and firmware execution, while programmable blocks can implement functions such as timers, serial interfaces, comparators, and analog signal conditioning. This integration can reduce the component count in control, interface, and measurement designs compared with a discrete MCU-plus-support-chip approach. The CY8C22213 belongs to the CY8C22xxx family and is identified as an 8-bit device with a 24 MHz operating frequency. Its flash program memory is 2 KB, or 2K x 8, and the device is supplied in a 32-QFN package with an exposed pad according to distributor package information. The compact land pattern supports space-constrained industrial control, embedded instrumentation, and auxiliary signal-conditioning designs. The mixed-signal architecture separates control processing from configurable peripheral resources. This allows firmware to service timing and communication tasks while analog and digital blocks handle peripheral functions. The 2 KB flash capacity is appropriate for compact control loops, configuration tables, boot logic, and modest protocol stacks, but it should be checked against firmware size before the design is released for production. Typical applications include industrial sensor interfaces, low-cost control panels, analog monitoring systems, compact data-acquisition modules, and embedded controllers that require programmable analog behavior. In these systems, the device can reduce interconnect complexity by handling sensing, thresholding, timing, and control functions within one mixed-signal architecture. Designers should confirm the exact exposed-pad connection, operating-voltage limits, peripheral availability, and pin multiplexing against the manufacturer datasheet before layout release. The exposed pad normally requires a ground-plane connection and careful via placement for electrical and thermal performance. Firmware must also remain within the 2 KB flash budget, including boot code, interrupt routines, and application logic. This page consolidates lifecycle information, package details, parametric constraints, and obsolete-part replacement considerations that are distributed across individual catalog records. It also identifies where a PCB redesign or functional migration may be necessary because the CY8C22213-24LFI is listed as obsolete and no verified pin-to-pin cross-reference was available.

The Infineon Technologies CY8C22213-24PI is an 8-bit M8C PSoC 1 CY8C22xxx mixed-signal microcontroller operating at up to 24 MHz, with 2 KB of Flash memory in a 20-pin DIP package. It is designed for embedded control applications that require modest processing speed, digital I/O, and programmable mixed-signal functions in a through-hole package. A PSoC 1 mixed-signal array is a programmable system-on-chip architecture that integrates a microcontroller core with configurable analog and digital peripheral blocks. In the broader hierarchy, the CY8C22213-24PI belongs to the MCU -> embedded microcontroller -> mixed-signal controller family, combining sequential control with programmable sensor, timing, and interface functions. The verified product listing identifies the device as an M8C PSoC 1 CY8C22xxx microcontroller with 8-bit processing, a 24 MHz maximum clock, 2 KB Flash organized as 2K x 8, and a 20-DIP package. The -24PI suffix and distributor records identify the commercial ordering configuration used for procurement, while the exact electrical limits and peripheral details require the manufacturer datasheet for design release. 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.

PSoC 1 devices combine digital control with configurable analog and digital peripheral blocks, allowing compact designs to include sensing, control, and communication functions without relying on a large external component count. The CY8C22213-24SI is identified in the verified data as part of the CY8C22xxx PSoC 1 family and as an application processor. Its key verified attributes are 8-bit processing, 24 MHz maximum frequency, 2 KB flash, and a 20-SOIC package. The 20-SOIC outline is suitable for conventional surface-mount PCB assembly, while the limited flash capacity makes the device most appropriate for compact control tasks rather than storage-heavy firmware. Typical design roles include sensor conditioning and signal acquisition, industrial control, keypad and user-interface scanning, simple motor or actuator sequencing, and low-cost embedded products. The mixed-signal architecture can simplify boards that need both digital state control and analog functions. Exact pin functions, electrical limits, ADC resources, timers, and programming details were not supplied in the verified excerpts, so they should be confirmed against the manufacturer datasheet before schematic capture or firmware deployment. Designers should verify the exact clock, power, reset, I/O, and analog specifications from the official CY8C22213-24SI documentation. Because the retrieved snippets provide distributor and search metadata rather than a complete manufacturer specification table, unverified values are not inferred here. Confirm package dimensions, pin assignment, supply limits, operating temperature, memory map, and programming-tool support with the manufacturer documentation and the current distributor data.

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 design uses include industrial control interfaces, compact sensor-conditioning systems, temperature or light-control products, small motor-control loops, appliance controls, and communications-enabled embedded nodes. An 8-PDIP package also simplifies prototype construction and through-hole assembly, although production designs must consider mechanical spacing, programming access, and available board area. Designers should confirm the exact pin functions, supply limits, clock requirements, programming method, and peripheral configuration in the CY8C24123 datasheet before layout or firmware release. The supplied distributor data does not establish a current manufacturer lifecycle designation, price ladder, or a complete technical specification set. This page consolidates verified distributor facts, package information, application context, sourcing limitations, and a disciplined same-footprint replacement review. It intentionally avoids presenting unverified timing, memory, electrical, or lifecycle claims as guaranteed design data.

The CY8C25122-24PI is packaged as an 8-PDIP, also described in the verified sources as an 8-DIP with a 0.300-inch, 7.62 mm lead pitch. Its through-hole format is useful for prototypes, educational platforms, hand-built controllers, and test equipment where socketed or point-to-point construction is preferred. The PSoC architecture can simplify a mixed-signal control design by placing an embedded controller close to configurable analog and digital functions. This makes the family relevant to compact sensor interfaces, control panels, analog monitoring, and simple embedded products. Firmware capacity remains the principal constraint: 4 KB is suitable for focused control tasks rather than large protocol stacks or graphics-intensive applications. Typical uses include low-cost sensor controllers, building-control interfaces, compact analog measurement systems, laboratory fixtures, and educational embedded-control projects. The 24 MHz clock provides more timing headroom than slower 8-bit controllers, while the 8-bit architecture keeps implementation suitable for simple sequential control logic. Designers should verify the complete pin-level electrical characteristics, power requirements, memory map, and programming procedure in the manufacturer datasheet before layout. Because this is an 8-PDIP, preserve adequate spacing around the through-hole footprint and plan for programming/debug access. Firmware sizing must include boot, application, interrupt, and configuration overhead within the 4 KB flash limit.

The 24 MHz M8C core can support time-based control and peripheral coordination, while PSoC configuration can reduce the number of discrete analog and digital functions required. The design should not assume that every external function is available without checking the device configuration table and pin multiplexing requirements. The 20-DIP package is particularly useful for through-hole prototypes and designs where a conventional DIP footprint is preferred over a fine-pitch surface-mount package. A key engineering consideration is that the -24PI suffix, package, temperature range, and device variant must match the original design exactly.

These verified values make the part suitable for embedded controls where local logic, analog measurement, and compact through-hole assembly are required. The 28-pin plastic DIP package supports conventional PCB mounting and prototyping, while the 24 MHz M8C processor provides the timing headroom expected from this legacy embedded family. The supplied sources emphasize the device identity and basic architecture but do not provide verified peripheral counts, voltage limits, ADC resolution, timer counts, or operating-temperature limits, so those values remain unspecified rather than being inferred. Typical design uses include industrial control modules, sensor-interface controllers, small motor-control systems, building-control equipment, and mixed-signal instruments. The programmable architecture is valuable when product variations can be addressed through configuration instead of a large discrete BOM. Developers must nevertheless verify the exact PSoC configuration, firmware image, resource assignments, and board behavior before production. For new hardware, begin with the manufacturer datasheet and confirm all 28 pin assignments, supply requirements, programming connections, and mixed-signal resource availability. PSoC Designer and the associated device support flow may be relevant for configuring and programming this family, but tool-version availability should be confirmed before committing a design. This page combines the verified distributor identity, package and memory data with practical sourcing and design guidance. It deliberately distinguishes verified facts from parameters that were not supplied, helping engineers evaluate the CY8C26443-24PI without confusing a family-level capability with a guaranteed orderable-device specification.
