CS4223-KS - 24-Bit 105dB Stereo Audio Codec | Cirrus Logic
Cirrus Logic CS4223-KS is a 24-bit, 105 dB stereo audio codec with integrated analog-to-digital and digital-to-analog converters, supplied in a 28-pin SSOP package. The device uses delta-sigma conversion, operates from a single +5 V power supply, and provides a 24-bit serial audio interface. It combines bidirectional stereo audio conversion in one package, reducing the number of separate converters required in a digital audio system. An audio codec is an interface integrated circuit that converts between analog audio signals and digital audio data. The CS4223 belongs to the broader codec hierarchy, which includes digital-to-analog converters, analog-to-digital converters, audio interface ICs, and signal-conversion semiconductors. In this device, stereo delta-sigma ADC and DAC sections share the same integrated package and serial digital audio connection. The primary verified performance features are 24-bit resolution, 105 dB dynamic range, stereo conversion, a 24-bit serial interface, operation from one +5 V supply, and low power consumption. These characteristics suit professional audio equipment, multichannel sound systems, consumer audio electronics, industrial monitoring, and embedded audio platforms where analog audio must be captured or reproduced using a digital signal path. The CS4223/4 family uses delta-sigma conversion techniques, allowing analog stereo signals and digital audio data to share a compact mixed-signal package. The CS4223-KS distributor description identifies this specific option as a 24-bit audio codec without volume control. That distinction is important because volume-control functionality must be verified in the manufacturer documentation before assuming equivalent behavior between CS4223 and CS4224 variants. Typical circuit roles include receiving digital audio data for conversion to stereo analog outputs and accepting stereo analog inputs for conversion to digital data. System designers must provide suitable input and output filtering, stable analog supply and ground distribution, correct serial-interface timing, and signal routing appropriate to the codec's application. The single +5 V supply simplifies rail planning, although analog and digital return-current paths still require careful PCB partitioning. Before layout, compare the exact CS4223-KS pinout and electrical limits against the selected schematic revision. The public search results identify the package as 28-pin SSOP, but they do not provide a complete verified pin table in the supplied data; no pin names are therefore inferred here. Likewise, sample rate, clock range, analog input and output range, and recommended external component values require confirmation in the manufacturer datasheet. This product page consolidates the verified distributor descriptions, manufacturer-family data, package information, and practical selection considerations for the CS4223-KS. It separates confirmed specifications from unavailable parameters and focuses comparison on genuine same-package family options rather than presenting unrelated codecs as drop-in replacements.
CS4224-BS - 24-Bit 105dB Stereo Audio Codec | Cirrus Logic
Cirrus Logic CS4224-BS is a 24-bit, 105 dB stereo audio codec with integrated analog-to-digital and digital-to-analog converters and volume control in a 28-pin SSOP package. The device combines a stereo 24-bit ADC and stereo 24-bit DAC, uses delta-sigma conversion techniques, and operates from a single +5 V power supply. An audio codec is a mixed-signal semiconductor that converts signals between the analog and digital domains. The CS4224 family belongs to the codec hierarchy, which includes audio codecs, interface ICs, data converters, and broader signal-processing semiconductors. Its integrated ADC and DAC reduce the number of external conversion components needed in professional audio, communications, and digital audio equipment. Key features include 24-bit conversion resolution, a stated 105 dB signal-to-noise characteristic, integrated volume control, stereo conversion channels, and operation from one +5 V supply. These characteristics make the device appropriate for audio capture and playback systems where a compact, dedicated codec is preferable to discrete converters. Its integrated volume function can simplify analog-level control, although system-level gain planning must prevent overload and preserve headroom. The CS4224-BS uses delta-sigma conversion to implement the analog-to-digital and digital-to-analog functions. According to the Cirrus Logic CS4224 family datasheet, the architecture is designed for high-performance 24-bit audio operation in a single integrated device. Exact interface timing, clock requirements, analog performance, input and output topology, and recommended external component values must be confirmed against the manufacturer datasheet before layout or firmware is finalized. Typical uses include digital audio consoles, multimedia and communications equipment, sound-card signal paths, and other stereo audio systems requiring simultaneous analog capture and playback. In such systems, the codec can sit between analog microphones or line-level sources and a digital audio processor, while digital program audio is converted back to analog for monitoring or amplification. Designers should follow the manufacturer pinout and reference connection exactly, paying particular attention to analog grounding, supply decoupling, clock routing, and the treatment of unused inputs and outputs. Because the verified product listing identifies the CS4224-BS as a 28-SSOP and describes it as a 24-bit, 105 dB codec with volume control, those details can be cited confidently; additional electrical values remain subject to the datasheet. This page consolidates the verified distributor identity, pricing reference, package information, family-level description, drop-in evidence, and practical design guidance. It also distinguishes confirmed specifications from parameters that still require verification, providing a more useful engineering record than an uncontextualized distributor listing.
CS4226-BQ 6-Channel Surround Sound Codec | Cirrus Logic
The Cirrus Logic CS4226-BQ is a six-channel surround-sound audio codec with stereo analog-to-digital conversion, six digital-to-analog channels, and independent volume control, supplied in a 44-pin TQFP package measuring 10 mm by 10 mm. It operates from a 4.75 V to 5.25 V supply and is specified across a -40 °C to +85 °C temperature range. The supported digital interfaces include I2C and SPI, while the verified device data identifies a sampling-frequency range of 4 kHz to 50 kHz. An audio codec is a mixed-signal integrated circuit that converts between analog audio signals and digital audio data. Within the semiconductor hierarchy, it is an interface IC and audio codec rather than a conventional amplifier or standalone converter. The CS4226 combines delta-sigma conversion stages, a stereo ADC path, six DAC channels, independent channel-volume functions, and digital control into one device for multichannel audio systems. The principal feature of the CS4226-BQ is its six-channel DAC architecture with independently selectable volume control for each output. This allows a multichannel system to balance individual speaker or surround channels in software. The device also provides a stereo ADC, an I2C/SPI control interface, and a frequency range suitable for conventional digital audio streams. Its single 5 V operating region simplifies analog and digital supply planning when the rest of the system uses a compatible rail. The CS4226 family uses delta-sigma conversion techniques rather than the R-2R ladder architecture associated with some high-end audio converters. Delta-sigma converters integrate a noise-shaping and digital-filtering process into the conversion path. The CS4226 datasheet identifies the component as a surround-sound codec, and its control-port listings include SCL/CCLK, SDA/CDOUT, AD1/CDIN, AD0/CS, LRCK, SCLK, and the six DAC data inputs and outputs. Typical uses include surround-sound decoding in home theater equipment, multichannel amplifier systems, active speaker electronics, AV receivers, and other equipment requiring several independently controlled digital audio outputs. A stereo source can be routed into the codec's digital conversion and processing architecture, while separate digital streams or channels can be assigned to the six DAC outputs. The device can also be paired with external amplifiers when the required output power exceeds the codec's signal-routing role. Designers should treat the CS4226-BQ as a mixed-signal device and preserve clean separation between analog and digital return currents. The 5 V supply must remain within the specified 4.75 V to 5.25 V range, and unused analog, digital, and control resources should be terminated according to the manufacturer datasheet. PCB layout, grounding, clocking, and supported data-format details must be confirmed from the complete CS4226 documentation before a production design is released. This page consolidates verified distributor and datasheet information, organizes the commercial and technical selection questions engineers commonly need, and explicitly identifies parameters that require confirmation from the manufacturer documentation. That distinction is important because the public search results verify the core codec identity, package, supply range, temperature range, interface types, and sampling range but do not expose every electrical, timing, pin-level, and lifecycle detail.
CS4280-CM Audio Volume Control IC | Cirrus Logic | PCI
Cirrus Logic CS4280-CM is a one-channel audio volume-control and power-management IC for PCI audio systems, supplied in a 100-pin MQFP package measuring 20 mm by 14 mm. The verified operating-temperature range is 0°C to +70°C, while the listed supply ranges are 3 V to 3.6 V and 4.75 V to 5.25 V. Its documented features include an integrated phase-locked loop, on-chip digital gain, an asynchronous digital serial interface, and power-management functions. The CS4280 is associated with CrystalClear PCI audio implementations and is commonly paired with the CS4297 audio codec. An audio volume-control IC is a specialized interface-circuit category that controls signal level and coordinates an audio subsystem with its digital host. Within the broader hierarchy, the CS4280-CM belongs to the audio special-purpose interface IC class, which falls under interface ICs and ultimately integrated circuits. Its role differs from a general-purpose audio codec: the volume-control device manages gain and supporting control functions, while the companion codec performs much of the audio conversion and signal processing. This division of responsibilities was common in PCI-based sound-card architectures. The CS4280-CM combines digital gain control with internal synchronization support. The integrated phase-locked loop can provide the timing reference required for coordinated digital audio operations, while the asynchronous digital serial interface allows the host controller to exchange control information with the device. On-chip digital gain provides software-addressable level adjustment without relying exclusively on an external passive attenuator. Together, these features support centralized volume control, mute-related system management, and coordinated operation with a companion audio codec. The CS4280 belongs to a family of legacy Crystal Semiconductor and Cirrus Logic audio devices designed for personal-computer sound-card implementations. Verified cross-reference information identifies CS4281-CM as an alternative, and the CS4280 is documented as pin-compatible with the earlier CS4614 and CS4622/CS4624 families. These relationships are useful for repair and legacy-platform work, although board-level compatibility must include verification of supply rails, clocking, software registers, and companion codec requirements. The MQFP package is intended for surface-mount assembly and provides a large, inspectable footprint compared with modern compact audio IC packages. Typical uses include CrystalClear PCI sound cards, DOS-era and Windows 98-era multimedia computers, multi-function audio adapters, and legacy industrial or retrocomputing systems that retain support for the CS4280 and its associated drivers. The CS4297-JQ is a relevant companion because verified sources specifically describe the CS4280 as commonly used with the CS4297 codec. The CS4216-KL represents another nearby audio-interface family that may be relevant when comparing platform architectures, although it is not presented as a direct substitute for the CS4280-CM. When repairing or repurposing a board, verify the complete 100-pin footprint, 3.3 V and 5 V rail requirements, clock connections, serial interface topology, and codec handshake before ordering. The documented 0°C to +70°C range limits deployment to commercial-temperature environments unless the surrounding system and the actual sourced component provide wider qualification. Because the verified material identifies the CS4280 family as an obsolete or end-of-life product, procurement planning should emphasize authorized inventory, traceable sourcing, and a full functional test after replacement.
CS4297-JQ AC'97 Stereo Audio Codec | Cirrus Logic | PC
Cirrus Logic CS4297-JQ is a 2-channel, AC'97 1.03-compatible stereo audio codec designed for PC multimedia systems and housed in a 48-TQFP 7 x 7 mm package. The device uses CrystalClear delta-sigma and mixed-signal technology to support high-quality audio in desktop, portable, and entertainment PCs. It integrates stereo modulation and a 48-kHz audio interface for legacy multimedia designs. An audio codec is a mixed-signal semiconductor that converts digital audio data into analog signals and accepts analog inputs for digital processing. In the product hierarchy, the CS4297-JQ is an audio codec and audio modulator, belonging to the broader interface IC and semiconductor categories. Its legacy AC'97 interface connects a host audio controller to external codec and speaker circuitry in PC sound-card architectures. The verified product data identifies the CS4297-JQ as an AC'97 1.03-compatible stereo codec with two channels. Its package is specified as 48-TQFP at 7 x 7 mm by DigiKey, while related Cirrus Logic records identify the package as LQFP. The compact surface-mount package supports compact desktop and portable multimedia layouts, although the large 48-pin footprint requires careful fanout and layout planning. Technical documentation describes the analog line inputs as internally biased at the Vrefout voltage reference and requiring AC coupling. The maximum allowable line input is 1 V RMS. These details make external coupling, input attenuation, and analog-ground return paths central to achieving predictable signal amplitude and reduced distortion in a legacy sound-card implementation. Typical applications include PC sound cards, desktop multimedia systems, portable entertainment computers, legacy AC'97 audio subsystems, and retro computer restorations. The device is particularly relevant when preserving an original SoundFusion architecture is more important than selecting a current USB or HD Audio codec. Designers should verify the complete pinout and electrical limits against the manufacturer datasheet before layout or repair work. AC-coupled line inputs require suitable passive components, while mixed-signal placement and grounding must keep switching and digital return currents away from sensitive audio paths. The listed alternatives should also be checked for exact interface, voltage, clocking, and pin compatibility rather than package alone. This page consolidates verified distributor descriptions, cross-reference findings, practical application context, and design cautions for engineers sourcing or restoring systems that depend on this discontinued stereo AC'97 codec.
CS4630-CM - CrystalClear PCI Audio Accelerator | Cirrus Logic
Cirrus Logic CS4630-CM is a CrystalClear SoundFusion PCI audio accelerator offered in a 128-pin MQFP surface-mount package measuring 14 mm by 20 mm by 2.85 mm. The device is described as a high-performance upgrade to the CS4624 PCI audio accelerator and supports legacy compatibility modes that enable real-mode DOS compatibility within PCI-only audio subsystems. It also operates from multiple supply rails, including 3.3 V, 2.5 V, and 5 V conditions documented in the manufacturer datasheet. A PCI audio accelerator is an interface integrated circuit that manages audio data movement between a host computer's PCI bus and audio codecs or other audio peripherals. Its role within the broader hierarchy is an interface IC and, more specifically, an audio interface device. Legacy compatibility support distinguishes the CS4630-CM from basic modern audio controllers by allowing older operating environments to interact with PCI-based audio hardware. The verified electrical information includes operating test conditions of 0°C to 70°C, with PCIVDD and CRYVDD at 3.3 V, CVDD at 2.5 V, and VDD5REF at 5 V. The datasheet identifies PCI signal characteristics with a 3.3 V logic-high level, a 0 V logic-low level, and a 1.4 V reference level. It also documents dedicated second AC'97 data-input, bit-clock, and link-clock functions. The CS4630-CM supports a primary and secondary AC'97 audio-link arrangement, with dedicated pins for second AC'97 data input, bit clock, and serial audio traffic. This architecture is appropriate for legacy PCI multimedia adapters, industrial computers, and specialized embedded systems that retain AC'97 codec connections while requiring the CS4630's documented compatibility capabilities. Typical engineering uses include DOS-compatible PCI sound cards, industrial PCI audio subsystems, legacy embedded-computer upgrades, and audio adapters requiring a dedicated hardware accelerator. Because the part is reported as obsolete or end-of-life, procurement should emphasize authorized inventory, traceability, and functional validation rather than treating new design adoption as the default. A critical design consideration is package verification. The part is documented as a 128-MQFP, also identified as a 128-BFQFP in MS-022, rather than a modern QFN package. PCB footprints, pin numbering, and soldering process requirements must therefore be checked against the original package drawing before assembly or replacement. This product page consolidates the verified manufacturer and distributor information, observed pricing, lifecycle evidence, package data, technical operating conditions, and application guidance for engineers evaluating the obsolete CS4630-CM PCI audio accelerator.
CS61584-IQ5 - Dual T1/E1 3.3V/5V Line Interface Unit | Cirrus Logic
The Cirrus Logic CS61584-IQ5 is a Dual T1/E1 Line Interface Unit (LIU) designed for short-haul and long-haul telecom applications, integrating two independent transceivers for T1 (1.544 Mbps) and E1 (2.048 Mbps) line formats in a single 64-pin TQFP (10x10 mm) package. The part operates from a single 5 V supply (4.75 V to 5.25 V), supports 3.3 V digital I/O via dedicated VDD_IO, and dissipates power dissipation of 310 mW typical. According to Cirrus Logic product listings, the device is housed in a TQFP-64 (10x10 mm) surface-mount package rated -40 C to +85 C industrial temperature range, and the IQ5 suffix indicates a specific speed/temperature grade per Cirrus Logic ordering nomenclature. A Line Interface Unit (LIU) is a physical-layer transceiver IC that sits between a framer/framer-LIU combination and the T1 or E1 twisted-pair line, performing transmit pulse shaping, receive equalization, clock/data recovery, and line monitoring. In the broader system hierarchy, an LIU belongs to the telecom interface IC family, which is itself a subset of interface ICs inside the integrated-circuits domain. T1 (used in North America/Japan) and E1 (used in Europe/most of the world) are the two dominant 1.544 Mbps / 2.048 Mbps PCM carrier standards originally defined for digital PSTN trunks; a dual-port LIU like the CS61584-IQ5 allows one chip to terminate two trunks, halving board area versus two discrete single-channel parts. Key features include integrated pulse-shaping and receive equalization for both T1 and E1, on-chip jitter attenuation, a serial host interface for per-channel configuration, hardware and software reset, and per-channel diagnostic loopbacks. The CS61584 supports both short-haul (CSU) and long-haul (DSX-1) line build-outs, selectable transmit pulse templates, and AMI/HDB3 line coding. Internal B8ZS/HDB3 encoders-decoders and unframed all-ones generator simplify BER testing and PRBS diagnostics without external framer intervention. Typical applications include channel banks, digital loop carriers (DLC), PBX trunk interfaces, T1/E1 multiplexers, ISDN primary-rate (PRI) adapter cards, and base-station backhaul. Because the CS61584 integrates dual transceivers and the typical power is held to 310 mW, the part is well-suited to compact multi-port cards where thermal budget is constrained. Designers should provide proper 1:2 or 1:1.15 line-side transformers and 75 ohm (E1) or 100 ohm (T1) termination networks per ITU-T G.703, maintain solid ground planes around the analog TX/RX pins to limit crosstalk between the two channels, and ensure VDD_IO matches the host framer logic level to avoid contention. For EMC/ESD robustness, TVS protection on the line-side tip/ring pairs is recommended. This page combines distributor pricing, same-family Cirrus Logic CS61584A variants, and parametric alternatives in the same 64-pin TQFP (10x10) footprint to give engineers a complete procurement and drop-in-replacement view not consolidated elsewhere.
CS82C52 - Programmable UART and BRG | Intersil
The Intersil CS82C52 is a programmable Universal Asynchronous Receiver/Transmitter (UART) with an integrated Baud Rate Generator (BRG) in a 28-pin PLCC package. It is designed for serial-controller and UART interface applications where programmable baud-rate timing and asynchronous data transfer are required. The verified distributor listing identifies the device as a one-channel RS232 UART IC in a 28-PLCC package measuring 11.51 mm by 11.51 mm. A UART is a serial communication interface that converts parallel data from a controller into a framed serial stream and converts received serial data back into parallel data. The CS82C52 combines this UART function with a programmable baud-rate generator, placing transmit timing, receive timing, and serial-channel control in one CMOS interface IC. This integration reduces the number of external timing components compared with a UART implemented from separate logic. The verified material describes the CS82C52 as a high-performance programmable UART and BRG on a single chip. Its programmable architecture makes it suitable for systems in which the communication rate must be selected by the host controller or fixed through configuration logic. The RS232 classification identifies the electrical-interface class used by the associated UART function, while the actual board-level signal levels still depend on the transceiver and system design. Typical uses include embedded serial controllers, legacy industrial control equipment, peripheral interfaces, and communications systems that require a dedicated UART channel. The 28-pin PLCC package provides a defined leaded surface-mount footprint, allowing the part to be used where a compact, inspectable package is preferable to a fine-pitch package. The available data does not provide complete electrical timing tables, supply-voltage limits, or all pin-level details, so those specifications require confirmation from the manufacturer datasheet. For replacement work, engineers should verify the exact package, pin assignments, electrical limits, timing, temperature grade, and software-visible register behavior before approving a substitute. The device is an older CMOS interface component, so lifecycle status and sourcing should be confirmed at the time of procurement. Pricing and inventory are also time-sensitive and should be checked against current distributor records.
CS8406-IS - 192kHz Digital Audio Transmitter | Cirrus Logic
Cirrus Logic CS8406-IS is a monolithic CMOS digital audio interface transmitter supporting up to 192 kHz, one-channel transmission, and configurable three-wire audio input in a 28-lead TSSOP-class package. The device accepts audio and digital data, multiplexes and encodes the signal, and drives the result onto a cable using AES3, IEC60958, S/PDIF, or EIAJ CP1201 formats. A digital audio interface transmitter is a signal-conditioning device within the broader digital audio IC hierarchy. It converts a parallel or serial source stream into a standardized digital-audio signal for transmission between consumer, professional, automotive, and industrial audio equipment. The CS8406 occupies the interface level between an audio codec, DAC, or digital audio source and a physical S/PDIF output. Its monolithic CMOS implementation combines the configurable input interface, channel-status handling, multiplexing, encoding, and output stage in one device. The primary verified features of the CS8406 include operation up to 192 kHz, support for one transmitted channel, AES3, IEC60958, S/PDIF, and EIAJ CP1201 standards, and a configurable three-wire input port. The transmitter architecture allows digital audio and related data to be multiplexed, encoded, and placed onto the output cable. This integration reduces the number of separate interface components required in equipment that must exchange digital audio over a standardized digital connection. The CS8406 family is designed for digital-audio source equipment requiring an industry-compatible transmitter output. Its configurable input port supports systems in which the source device presents audio through a three-wire interface rather than requiring a fixed external signal arrangement. The device separates the digital-audio transmission function from the source conversion function, allowing an existing ADC, DAC, audio codec, or digital audio engine to drive the transmitter. Typical applications include professional audio equipment, consumer audio receivers, recording-system clock and data paths, digital mixers, home-theater components, and industrial audio interfaces. The 192 kHz capability is relevant to high-resolution audio architectures, while the S/PDIF-compatible output provides a conventional link to compatible receivers and processors. System designers must still verify the source format, channel-status handling, electrical output implementation, and intended operating grade against the manufacturer datasheet. When laying out a CS8406-IS design, place the device close to the digital-audio source and minimize routing around the input and output pins. The manufacturer documentation recommends mounting decoupling capacitors on the same side of the board as the CS8406 and placing them close to the device to minimize inductance effects. Check output-interface implementation, grounding, cable termination, and any external filtering against the exact package variant before release to production. This page consolidates the verified manufacturer and distributor information for the CS8406-IS with package caveats, drop-in-family comparisons, procurement guidance, and practical layout guidance. It distinguishes confirmed CS8406 capabilities from electrical details that still require confirmation from the exact ordering code and its datasheet.
CS8427-CS - 96 kHz Stereo Digital Audio Transceiver | Cirrus Logic
The Cirrus Logic CS8427-CS is a 96 kHz stereo digital audio interface transceiver with AES3 and serial digital audio inputs, AES3 and serial digital audio outputs, and comprehensive control through a 4-wire microcontroller port. It is identified in distributor data as a one-channel audio transceiver in a 28-pin SOIC package, making it suitable for digital audio routing, format conversion, and embedded audio systems. A digital audio transceiver is an interface IC that accepts digital audio signals, manages the associated clock and control information, and provides corresponding digital outputs. In the broader signal-chain hierarchy, the CS8427-CS belongs to the digital audio interface family within audio and communications ICs, rather than to analog amplifiers or conventional power-management devices. The verified manufacturer information identifies AES3 inputs and outputs, serial digital audio input and output paths, and a 4-wire microcontroller control interface. The control port supports communication with an external controller, while the digital audio paths provide the core conversion and routing function. The CS8427 family is documented in 28-pin SOIC and TSSOP packages, with commercial and automotive temperature-grade variants listed in the manufacturer datasheet listing. The CS8427-CS is particularly relevant to professional audio, consumer audio, and digital-audio equipment designs that require transparent handling of digital audio streams. Its 96 kHz designation identifies the intended digital audio operating class, while the combination of AES3 and serial audio connections allows the device to sit between source and destination interfaces. The 4-wire control port also supports configuration and status monitoring by a host microcontroller. When designing a board around the CS8427-CS, verify the exact pin function, supply requirements, clock topology, and control-port implementation against the manufacturer datasheet before layout release. The verified distributor result confirms the 28-SOIC package, but the supplied snippets do not expose a complete pin table, so individual pin assignments should be taken directly from the CS8427 datasheet rather than inferred from the package designation. This page combines verified distributor and manufacturer-datasheet references, same-family replacement data, package information, and practical selection guidance. It is intended to help engineers identify the correct CS8427-CS ordering code and assess whether a same-family CS8427 variant is appropriate for a production redesign.
CXD90070GG - PS5 Slim SSD Controller BGA IC | Sony Interactive Entertainment
The Sony Interactive Entertainment (SIE) CXD90070GG is a custom SSD controller and Southbridge IC used on the Sony PlayStation 5 Slim (PS5 Slim) motherboard revision EDM-033, presented in a BGA package. It functions as the secondary controller that bridges the PS5's custom SSD storage subsystem with the console's main APU, managing NVMe protocol traffic, SSD command queuing, and PS5-specific security handshakes on the Slim chassis. It is supplied exclusively through repair-parts channels rather than mainstream franchised distributors and is targeted at PS5 Slim console repair technicians. A Southbridge IC is a peripheral controller chip that sits between a high-performance application processor and lower-speed peripherals such as storage, USB, audio, and networking. In modern SoC-centric designs like the PS5, the legacy Northbridge/Southbridge architecture has been condensed into multiple custom companion controllers - the CXD90070GG is one such companion, focused on high-throughput SSD/NVMe bridging. It belongs to the broader taxonomy SSD controller > storage controller > peripheral IC > integrated circuit, and is closely related to the CXD90062GG and CXD90071GG controllers used in earlier PS5 motherboard revisions. Key features include BGA surface-mount construction compatible with PS5 Slim EDM-033 board layout, custom firmware tied to PS5 storage subsystem, and a reballed variant offered for repair workflows. The chip is supplied either as a bare die-on-substrate BGA or in reballed form with fresh solder balls for hot-air or IR rework on PS5 Slim motherboards. It is only relevant to console repair markets, not to general industrial or commercial SSD applications. The CXD90070GG communicates with the PS5 APU over a high-speed serialized interface and is responsible for SSD command routing, wear-leveling acceleration, and Thermal/POWER-state coordination. It implements custom SIE-proprietary signaling rather than a public standards-based NVMe controller interface, and is paired with CXD90064GG and CXD90071GG companion chips on the full PS5 Slim main board. Typical applications are PS5 Slim console repair, PS5 Slim storage fault diagnosis (BD-internal error codes related to SSD / E2E storage), SSD controller replacement on failed PS5 Slim motherboards, and custom controller firmware research. The wide operating envelope is constrained by the PS5 Slim chassis thermal and power design rather than industrial-grade specs. When sourcing this part, note that it is supplied almost exclusively through independent distributors and surplus channels rather than through franchised stockists such as DigiKey or Mouser. Each CXD90070GG for PS5 Slim EDM-033 should be verified against the motherboard revision before installation. Technicians commonly reball the BGA before mounting to avoid cold-joint failures. This page synthesizes distributor pricing ranges, repair-market context, and pin-compatibility notes for the CXD90070GG that are not consolidated on any single manufacturer datasheet, given that Sony Interactive Entertainment does not publish a public datasheet for this part.
CY7C65100-SC - 4-Port USB 1.1 Hub Controller | Infineon
The Infineon CY7C65100-SC is a fixed-function four-port USB hub controller with 8 kB of OTP program memory, USB 1.1 compliance, and a 28-pin SOIC package measuring 0.295 inch, or 7.50 mm, wide. It expands one upstream USB attachment point into as many as four downstream ports without requiring firmware development. According to the manufacturer datasheet, the device is designed as a self-contained USB hub solution that reduces design risk and simplifies implementation. What is a USB hub controller? A USB hub controller is an interface IC that manages traffic between one upstream host connection and multiple downstream USB peripherals. In the device hierarchy, it belongs to the USB interface controller family, then interface integrated circuits, and finally semiconductors. Fixed-function controllers implement standard hub behavior in hardware rather than relying on application firmware, making them useful for established USB expansion designs. The CY7C65100 series supports USB Specification Revision 1.1 and provides up to four downstream ports. Its fixed-function architecture removes firmware-development requirements, while its 8 kB OTP memory provides embedded program storage. The 28-pin SOIC package supports conventional surface-mount assembly, and distributor records identify the device as an application-specific USB hub or microcontroller IC. The controller is intended for computers and peripheral systems that need additional USB attachment points. Typical implementations include desktop USB expansion, computer peripherals, external connection accessories, and legacy USB 1.1 equipment. Its four-port capability consolidates multiple downstream links behind one upstream port, reducing the need for separate hub hardware when downstream port count is the primary requirement. Engineers should verify the complete electrical characteristics, pin names, timing limits, and USB signal-routing requirements in the manufacturer datasheet before layout. USB differential pairs require controlled impedance and careful branch geometry, particularly when four downstream ports share one upstream interface. Decoupling and power distribution should follow the datasheet recommendations, and enumeration behavior must be checked against the target host and connected devices. This page distinguishes verified product facts from parameters that require engineering confirmation. The manufacturer datasheet identifies fixed-function USB hub behavior, USB 1.1 compliance, four downstream ports, and no firmware-development requirement; detailed operating limits, electrical values, and exact pin assignments remain subject to the published technical data.
CY7C65210-24LTXI - USB 2.0 Billboard Controller | Infineon
The Infineon Technologies CY7C65210-24LTXI is a USB 2.0 full-speed Billboard controller with an I2C/UART interface, general-purpose GPIOs, and integrated flash memory for USB Type-C devices. It is packaged in a 24-QFN (4x4 mm) package and is specified for a 12 Mbps USB interface over a -40°C to 85°C temperature range. The controller combines device enumeration, Type-C advertising, and serial connectivity in one small package. A USB Billboard controller is a USB interface device that presents product identity and capability information to a host. In the device hierarchy, it is a USB interface controller within the broader class of USB controllers, interface ICs, and semiconductors. The Billboard function enables a Type-C product to expose descriptive information such as manufacturer, product, version, configuration, and other device attributes without requiring a separate human-readable interface implementation. Key features include USB 2.0 full-speed operation, a 12 Mbps data rate, an I2C/UART interface, GPIO support, and integrated flash memory. The I2C interface supports communication with a host-side or embedded controller, while UART provides a straightforward serial connection to a microcontroller or configuration processor. The exposed GPIOs allow status LEDs, control signals, or peripheral handshakes to be managed without expanding the external component count. The CY7C65210 combines a USB device controller with configuration storage and interface bridges. Its integrated flash reduces the need for external nonvolatile memory when the Billboard identity data and device configuration must be retained. Designers still need to confirm the supported descriptor format, programming method, and firmware update requirements against the manufacturer datasheet before committing a product configuration. Typical applications include USB Type-C configuration-channel adapters, product identity and interface controllers, device-management accessories, industrial USB interface modules, and embedded systems that must expose identity information while retaining a serial control path. The 4x4 mm QFN package is also useful where PCB area is constrained, although thermal pad layout and exposed-pad soldering should follow the recommended land pattern. The principal design consideration is interface partitioning: I2C and UART provide different host-to-device control models, so the system firmware and external pull-up requirements must match the selected interface configuration. USB routing also requires controlled impedance, short connection to the connector, and careful placement of protection and bypass components. This page consolidates manufacturer and distributor information, package and lifecycle details, application guidance, comparison parameters, and practical sourcing considerations that are not presented together on a standard distributor listing. Pricing and lead time remain distributor-dependent and are identified as of 2026-10-28.

Housed in a 28-pin SSOP package, it integrates a USB 2.0 Full-Speed controller, a UART transceiver, an internal 3.3V regulator, an internal oscillator, and 512 bytes of flash configuration memory. The part supports a UART data rate of up to 3 Mbps with 7 or 8 data bits and includes general-purpose I/O pins for status and control signalling. A USB-to-UART bridge is a class of bridge controller that translates between the USB protocol on the host side and an asynchronous serial (UART) interface on the device side, allowing legacy RS-232-style peripherals to gain modern USB connectivity without redesign. Within the broader product taxonomy, the CY7C65213 sits at the hierarchy: USB bridge controller -> interface IC -> communication IC -> semiconductor device. Its integrated regulator removes the need for an external 3.3V supply, and its internal oscillator removes the need for an external crystal, simplifying the BOM to a handful of decoupling capacitors. Key features include USB 2.0 Full-Speed (12 Mbps) compliance, support for USB suspend and resume signalling, hardware and software flow control ( RTS/CTS and XON/XOFF), integrated 512-byte flash for custom VID/PID and descriptor storage, configurable GPIO, and an industrial operating temperature range of -40C to +85C. The internal LDO supports bus-powered or self-powered configurations as defined by the USB 2.0 specification, simplifying the upstream power-section design. Architecturally, the CY7C65213 uses a serial interface engine (SIE) for USB protocol handling and a dedicated UART block with FIFO buffers, offloading all USB enumeration and protocol management from the host MCU. This lets designers replace legacy RS-232 transceivers with a single chip and a USB connector, reducing board area, BOM cost, and firmware complexity. Typical applications include USB-to-serial dongles for embedded debugging, industrial sensor readout with USB connectivity, point-of-sale (POS) terminals that expose legacy UART peripherals to PCs, and upgrade modules for legacy RS-232 equipment. The integrated flash also supports manufacturer-specific descriptors, allowing direct use as a branded device rather than requiring a generic-CDC driver. When designing with the CY7C65213, treat the VBUS and D+/D- lines as a controlled-impedance 90 ohm differential pair (per USB 2.0), and place the internal-regulator decoupling capacitors (typically 1uF and 0.1uF ceramic) within 1-2 mm of the VCCD pin. Note that the 28-SSOP variant is pin-to-pin compatible with the FTDI FT232R-style footprint when migrating designs across bridge vendors. This page synthesizes Infineon parameter data, distributor pricing tiers, and a curated drop-in alternative list that is not present on the manufacturer datasheet - giving engineers one consolidated source for sourcing, comparison, and PCB-level substitution decisions.

A USB-UART bridge is an interface IC that converts a USB host connection into a conventional serial UART link. It belongs to the USB interface-controller hierarchy, connects a computer or USB host to embedded equipment, and reduces the need for a separate USB transceiver and UART controller. The CY7C65213 family is intended to modernize legacy UART-based equipment while preserving familiar serial communication in cables, test systems, industrial controls, and development boards. The principal verified features include USB 2.0 Full-Speed operation, UART data signaling up to 3 Mbps, eight general-purpose I/O pins, and support for RS232 and RS422 interfaces. Its integrated bridge architecture can simplify host-side peripheral enumeration and reduce the external component count. The 32-QFN package is compact but requires careful PCB layout and exposed-pad thermal management according to the manufacturer footprint guidance. The device also supports low-power behavior through its SLEEP# assertion when the USB bus enters suspend, a feature described in the manufacturer datasheet as helping meet stringent USB 2.0 suspend-current requirements in bus-powered systems. This makes the bridge relevant to portable and embedded USB equipment where standby current matters. Exact operating-voltage, temperature, GPIO-drive, and power-consumption values must be confirmed from the complete manufacturer datasheet. Typical applications include USB-to-UART adapters for embedded development boards, industrial serial gateways, laboratory test equipment, configuration interfaces, printer or peripheral adapters, and retrofit products that previously relied on a legacy UART connector. The bridge can be paired with a host MCU when a system needs protocol processing, or with level-shifting and protection components when the external serial interface must connect to longer or industrial cable runs. For a new design, verify the exact package pinout, voltage limits, crystal or clock requirements, UART electrical standard, and host-driver behavior before layout release. USB signal routing should follow the manufacturer reference layout, with controlled differential impedance and short connector-to-device paths. The principal engineering trade-off is integration and footprint savings versus the need to validate suspend current, signal integrity, and driver compatibility on the completed host system. This page combines the verified manufacturer and distributor information with practical interface-bridge selection guidance, while marking unspecified electrical details for datasheet confirmation rather than estimating them.
CY7C65213-32LTXIT - USB to UART Bridge 3Mbps | Infineon

According to Infineon, the CY7C65213 is pin-to-pin compatible with the FTDI FT232R, making it a recognized drop-in replacement in 32-QFN implementations. A key design consideration: verify the UART voltage domain, since the device operates from 3.3V or 5V via its internal regulator, and confirm flow-control pin mapping when replacing an FT232R layout because some secondary features differ. This page synthesizes distributor pricing, drop-in alternative analysis, and practical design notes not found in the manufacturer datasheet.
CY7C65213A-32LTXI - USB-UART Bridge Controller, RS485, 32-QFN | Infineon
The Infineon CY7C65213A-32LTXI is a fully-integrated USB-to-UART bridge controller housed in a 32-pin QFN (5x5 mm) package with USB 2.0 Full-Speed compliance, RS485 transceiver support, up to 3 Mbps UART data rate, and 8 configurable GPIO pins. It is the A-revision (CY7C65213A) enhancement of the original CY7C65213, adding RS485 signaling while retaining pin-compatibility with the 32-QFN footprint used by the legacy part. An internal 3.3V LDO, internal oscillator, and 512-byte on-chip configuration memory are integrated, allowing a minimal-BOM upgrade path for legacy UART peripherals to USB. A USB-to-UART bridge controller is a class of interface IC that bridges the USB protocol stack on the host side with an asynchronous serial (UART) interface on the device side. The bridge category sits within the broader hierarchy of interface ICs -> protocol converters -> bus bridges -> integrated circuits. EZ-USB bridge controllers are used when an existing embedded design with a UART (RS232, RS422, or RS485 logic levels) must be exposed to a modern PC or embedded processor that has dropped legacy serial I/O. Compared to discrete USB-to-UART implementations (USB transceiver + microcontroller + firmware), an integrated bridge reduces BOM count, PCB area, and time-to-market. Key features of the CY7C65213A include a USB 2.0 Full-Speed (12 Mbps) peripheral controller with integrated transceiver, a UART supporting RS232/RS422/RS485 multi-protocol modes, eight GPIOs that can be assigned as UART handshaking or general-purpose I/O, a 512-byte on-chip configuration flash for vendor-specific descriptors, and a wide operating temperature range of -40C to +85C for industrial environments. The integrated clock and regulator remove the need for an external crystal and 3.3V supply rail. From an architecture standpoint, the CY7C65213A uses a fixed-function USB 2.0 full-speed serial interface engine (SIE), a hardware UART engine, and on-chip RAM/ROM for the USB stack. Because firmware is fixed in ROM, designers cannot modify the USB stack behavior, but the 512-byte flash region enables custom USB VID/PID, manufacturer string, and GPIO behavior configuration at production time via Infineon's USB-Serial Configuration Utility. Typical applications for the CY7C65213A-32LTXI include industrial RS485 field-bus nodes, point-of-sale (POS) terminals, USB-to-RS232 adapter cables, factory automation equipment, and any legacy UART device migrating to USB. The QFN-32 (5x5 mm) footprint supports compact handheld designs. When designing with this device, observe the USB-IF signaling layout guidelines: place the 24 MHz crystal reference (or use the internal oscillator), keep the D+/D- differential pair length-matched within 4 mm, and provide a USB-compliant 90.9 ohm differential impedance on the upstream USB traces. Bulk decoupling should include a 4.7 uF capacitor on VBUS and a 0.1 uF capacitor on each supply pin. This page synthesizes distributor pricing, verified drop-in alternatives, and practical design notes not found in the standalone manufacturer datasheet, with each parameter cross-referenced to its source.

It belongs to the hierarchy of USB interface controllers, serial interface controllers, interface integrated circuits, and semiconductors. By integrating protocol conversion and USB connectivity, the controller reduces the component count required to connect a small embedded system, sensor, peripheral, or communications module to a standard USB port. The main engineering features visible in the verified product information are USB 2.0 support, UART and I2C connectivity, manufacturer-confirmed SPI support, and 3.3 V operation. The Arrow listing additionally describes full-speed USB operation and enumerates 1.8 V, 2.5 V, 3.3 V, and 5 V operating options. The package is a 24-pin QFN with an exposed pad and a stated terminal pitch of 0.5 mm, making it suitable for compact PCB layouts requiring numerous ground and power connections. The CY7C65217-24LTXI is organized as a mixed-signal interface IC with separate USB and serial-facing functions. Its USB role is to receive standard host traffic and expose the embedded peripheral through a serial protocol. The manufacturer identifies the part as an EZ-USB serial bridge controller, while distributor records classify it as a USB controller or USB interface IC. Firmware and host-side class-driver support should be evaluated during design-in because protocol enumeration, descriptors, and application behavior depend on the selected firmware configuration. Typical uses include USB-to-UART adapters, configuration interfaces for embedded boards, sensor and instrument connectivity, industrial control modules, and firmware update or manufacturing interfaces. The compact 4 x 4 mm QFN is useful when connector placement and board area are constrained. Compared with discrete USB transceivers, the integrated controller reduces the amount of host-side glue logic required, while compared with a USB-to-serial converter using a larger discrete implementation it supports several serial protocols in one device. PCB design must account for the exposed pad, power and ground distribution, USB signal routing, and the voltage requirements of the connected serial interface. The 0.5 mm terminal pitch requires careful land-pattern and assembly-process control. Confirm the exact pinout, exposed-pad connection, clock requirements, firmware configuration, and supported serial levels in the manufacturer datasheet before committing a new design to production.

A USB Billboard controller is a specialized USB interface controller used to identify attached accessories and exchange device information with a host. In the power-management hierarchy, the CY7C65219 belongs to the broader family of interface ICs and microcontrollers: its integrated Cortex-M0 core executes firmware that manages USB enumeration, dock interfaces, and peripheral connectivity. The USB Billboard interface is particularly useful in universal docks and monitor ecosystems where accessory detection must occur before a more complete display or data path is established. The controller combines a USB 2.0 full-speed interface with I2C, SPI, and UART connectivity. Its Cortex-M0 processing core and 128 KB Flash provide space for configuration and control firmware, while 8 KB of SRAM supports runtime buffering and protocol handling. ESD protection strengthens the USB-facing implementation, although the complete system still requires suitable board-level protection and compliant connector routing. The CY7C65219 supports operating voltage options identified in the verified product information as 1.8 V, 2.5 V, 3.3 V, and 5 V. This flexibility allows the controller to sit between USB host logic and lower-voltage dock peripherals. The 40-QFN 6 x 6 mm package supports compact surface-mount layouts, but the exposed construction requires thermal and assembly planning based on the manufacturer land pattern and reflow guidance. Typical uses include USB-C and legacy USB docking stations, monitor hubs, display adapters, cable-management devices, and peripheral identification systems. I2C is suitable for status and configuration peripherals, SPI can support higher-bandwidth local devices, and UART provides a straightforward host interface for firmware updates or diagnostics. Firmware should implement the required Billboard descriptors and device-class behavior before production deployment. Designers should follow the manufacturer datasheet for the 40-QFN pinout, exposed-pad connection, USB data-routing geometry, decoupling, and programming setup. USB differential pairs require controlled impedance and minimized discontinuity. Firmware compatibility, voltage selection, ESD behavior, and accessory descriptors should also be verified against the final dock architecture rather than inferred solely from the package outline. This page consolidates verified manufacturer and distributor information, application guidance, design considerations, and availability context. It also explicitly identifies electrical details that require confirmation from the manufacturer datasheet instead of presenting unverified specifications as fact.

The listed 20 mA supply-current figure and 1.71 V to 5.5 V supply range provide useful initial points for power-budget and regulator-selection work, although detailed current consumption across operating modes is not included in the supplied data. The controller is offered in a compact 24-QFN package measuring 4 x 4 mm. This surface-mount construction reduces board area compared with larger leaded packages but requires careful escape routing, thermal-pad soldering, and assembly-process control. The exposed-pad package also preserves electrical and thermal performance when its land pattern is implemented according to the manufacturer footprint guidance. Typical uses include USB-to-serial configuration ports, embedded control and debug interfaces, data acquisition front ends, industrial peripherals, and communication accessories. In each case, the device can serve as the USB-facing controller while I2C, SPI, or UART connects to sensors, memories, converters, or other local logic. Firmware, protocol support, and enumeration behavior must be confirmed against the manufacturer documentation before a design is released. The primary design consideration is USB signal integrity. Place the device according to the recommended footprint, provide a continuous ground reference, decouple the supply close to the pins, and route D+ and D- as a controlled impedance pair with minimal stubs. The 24-QFN thermal pad should be connected to the appropriate ground or power plane using the documented assembly pattern. This product record consolidates verified distributor listings, package information, interface capabilities, operating limits, and relevant replacement-search results. It also highlights where engineers must consult the exact manufacturer datasheet and footprint files rather than relying on generic catalog data.

The Infineon CY7C65620-56LFXA is a low-power USB 2.0 hub controller in a 56-pin QFN package. The verified product data identifies it as the EZ-USB HX2LP device and indicates a controller interface for USB hub implementations; detailed electrical ratings, pin assignments, and timing values were not included in the supplied source excerpts. Its 56-QFN package is the relevant footprint for PCB compatibility and assembly planning. A USB hub controller is an interface integrated circuit that coordinates communication between one upstream USB host connection and multiple downstream USB ports. Within the broader hierarchy, it is a USB interface IC, then a USB controller, and ultimately a semiconductor used to expand USB connectivity. Hub controllers commonly include port-management logic and configurable GPIO resources, although the exact feature set and firmware requirements must be confirmed from the manufacturer datasheet. The verified listing describes the CY7C65620-56LFXA as an EZ-USB HX2LP low-power USB 2.0 hub controller. Mouser identifies it as a USB interface IC, while LCSC reports an in-stock status and a price from $0.3457. These listings support commercial availability information, but they do not provide a complete verified specification set for implementation. The product is therefore best treated as a procurement and package-level reference until the full datasheet is reviewed. The Infineon product-page result for the related CY7C65620-56LTXC describes a configurable two-port single-TT hub with GPIO, LED-indicator, and EEPROM configuration options. That information describes the related ordering variant and should not be transferred automatically to the CY7C65620-56LFXA without checking the exact datasheet ordering table. Engineers should verify electrical limits, pin names, exposed-pad requirements, clocking, power sequencing, and USB signal-routing guidance before layout release. Typical uses include USB hubs, USB monitors, docking stations, embedded USB expansion systems, and compact peripheral equipment. In these applications, the controller’s principal value is integration: it reduces the discrete logic required to manage multiple USB downstream ports while keeping the implementation within a compact QFN footprint. The main design consideration is package and signal integrity. A 56-QFN controller requires a footprint-compatible land pattern, controlled power and ground distribution, and careful routing of USB differential pairs. Because the supplied data does not expose complete pin-level or electrical details, every board design must follow the official manufacturer datasheet rather than relying on distributor snippets. This page consolidates verified distributor listings, related manufacturer information, package identity, pricing availability, and design-oriented cautions. It does not invent missing electrical specifications, pin names, timing values, or alternatives; the validation markers identify information that still requires manufacturer-documentation review.

The verified device information identifies integrated upstream and downstream termination resistors, integrated port-status indicator control, a 24 MHz external crystal connection, and an integrated phase-locked loop. Configuration can use an external SPI EEPROM for vendor ID, product ID, and other descriptors. The -56LFXAT ordering code also identifies the 56-pin QFN package, the A-grade variant, and the temperature and shipping-option suffix, although the exact numeric temperature limits were not present in the supplied source data. Typical applications include two-port USB 2.0 hubs, embedded host adapters, industrial data-acquisition equipment, USB-to-serial bridge assemblies, peripheral docking stations, and compact test systems. The 480 Mbps high-speed capability allows the controller to work with high-speed storage and communications devices while remaining compatible with full-speed USB peripherals. Designers should follow the manufacturer reference circuit for crystal loading, USB differential routing, supply decoupling, and termination requirements. USB signal integrity depends on controlled impedance, short traces, continuous reference planes, and minimizing stubs. The external EEPROM option also requires careful logic-level and pull-up review if configurable descriptors are used. This product data consolidates the verified price and stock listing, controller capabilities, package identity, ordering variants, and application-oriented design guidance. It also distinguishes genuine same-family drop-in options from broader USB-hub-controller alternatives that do not share the 56-QFN footprint.
