WM8998ECS/R - 24-Bit Hi-Fi Audio Hub | Cirrus Logic
N.º da peça: WM8998ECS/R ✓ AtivoWM8998ECS/R Visão geral
An audio codec is an integrated circuit that converts digital audio data into an analog output and converts analog microphone or line inputs back into digital data. In the product hierarchy, a codec is an audio interface IC within the broader class of interface ICs. The WM8998ECS/R is positioned for portable and embedded audio functions where component count, board area, and host connectivity are important design constraints.
The verified product listing specifically identifies a 24-bit HD audio interface, SLIMbus connectivity, and a 117-WCSP package. These confirmed attributes make the part relevant to smartphone, tablet, portable-media, headset, and embedded-audio designs. The 5.35 mm by 4.09 mm package reduces board footprint, although its 117-ball construction requires careful assembly, inspection, and PCB-layout planning.
Technical evaluation must be completed against the manufacturer datasheet because the supplied distributor results do not expose the complete electrical tables. Sample rate coverage, supported clock rates, microphone bias, codec specifications, digital levels, power-supply requirements, and thermal limits are not available in the verified data and therefore cannot be safely inferred. Designers should also confirm the exact exposed-pad, ball-map, and recommended-land-pattern details before layout release.
Typical implementation places the WM8998ECS/R between one or more analog audio transducers and a digital audio host connected through SLIMbus. Its integrated hub role can simplify system routing in devices containing speaker, headphone, microphone, and line-level audio paths. The correct external amplifiers, passive network, clocking, and decoupling must be selected from the manufacturer reference design rather than inferred from the distributor summaries.
The primary design consideration is PCB implementation. A 117-WCSP package has a much denser interconnect than a conventional leaded package and can create soldering, inspection, and repair challenges. Confirm whether the assembled board will use optical inspection or X-ray inspection, and use the manufacturer-approved footprint and reflow profile to reduce assembly defects. The verified data does not expose pin names, so a complete ball assignment cannot be published here.
This product record combines verified distributor pricing, package information, sourcing links, and engineering-oriented selection guidance. It also separates confirmed facts from unavailable datasheet parameters and avoids presenting generic codec specifications as facts about the WM8998ECS/R.

Aplicações típicas
WM8998ECS/R é adequado para 6 aplicaçãos: Portable Media Player, Headset and Headphone Interface, Smartphone-Style Audio Hub, Tablet Audio Subsystem, Voice-Controlled IoT Device, Embedded Audio Control Module.
Portable Media Player
The WM8998ECS/R fits portable media players because it combines a 24-bit HD audio interface with SLIMbus connectivity in a compact 117-WCSP package measuring 5.35 mm by 4.09 mm. A host processor can exchange digital audio data over SLIMbus while the codec manages the device's analog audio paths. Before finalizing the design, engineers must confirm the required sample rates, microphone and headphone circuitry, clock source, and supply voltages from the manufacturer datasheet. The verified data does not expose power consumption or codec signal-to-noise ratio, so battery-life and output-noise targets cannot be independently validated from the distributor records.
Recomendado
Headset and Headphone Interface
The WM8998ECS/R is a potential fit for wired headsets and headphone systems that use a digital host link and require integrated high-resolution audio routing. Its verified 24-bit HD audio identity and SLIMbus interface allow a portable processor to control digital playback without requiring a separate host-side audio data path. The 117-WCSP footprint can also reduce board area in space-constrained products. Exact headphone-drive capability, output impedance, pop-noise behavior, and channel topology remain unavailable, so the manufacturer reference design must confirm whether the part directly drives the intended load or requires an external amplifier.
Recomendado
Smartphone-Style Audio Hub
The WM8998ECS/R's combination of 24-bit HD audio, SLIMbus, and a 5.35 mm by 4.09 mm 117-WCSP package makes it relevant to smartphone-style multi-path audio architectures. It can serve as the interface between a digital application processor and analog microphone, headphone, or line-level stages, while the package preserves board area for other compact components. The verified records do not identify supported channel counts, microphone bias, headphone outputs, or power rails, so engineers should validate those requirements against the manufacturer datasheet before treating this part as a direct fit.
Recomendado
Tablet Audio Subsystem
The WM8998ECS/R can be evaluated for tablet audio subsystems that use a SLIMbus link between a host processor and a compact analog-audio subsystem. Its 24-bit HD audio designation supports high-resolution playback architectures, while the 117-WCSP package reduces the physical area required for the audio interface. A successful implementation still depends on confirming supported sample rates, clocking flexibility, power sequencing, microphone inputs, and analog routing. Those parameters are not present in the supplied distributor snippets, and the verified sources do not include an application circuit, so the manufacturer reference design is essential.
Recomendado
Voice-Controlled IoT Device
The WM8998ECS/R is suitable for preliminary evaluation in voice-enabled IoT products that capture microphone audio and route playback through a digital host processor. The verified 24-bit HD audio interface and SLIMbus connectivity provide a plausible architecture for preserving digital audio quality between the host and the analog transducer stages. The dense 117-WCSP package also supports compact hardware, but that same density increases PCB-layout and inspection complexity. Engineers must confirm microphone bias, ADC performance, power consumption, and supported clock rates before committing, because those details are absent from the supplied sources.
Recomendado
Embedded Audio Control Module
The WM8998ECS/R can be considered for embedded audio modules that use a serial digital host interface and need a compact audio-front-end component. SLIMbus connectivity offers a defined role between the module's processor and codec, and the 24-bit HD audio classification supports high-resolution signal paths. Its small 117-WCSP body may help reduce module area, although PCB assembly and test access require careful planning. The verified records do not establish industrial temperature range, power-rail limits, ESD performance, or long-term availability commitments, so qualification must use the complete manufacturer documentation.

Notas de projeto
Do not release the PCB footprint from a generic 117-WCSP drawing. Download the WM8998ECS/R package drawing and land pattern from Cirrus Logic, then verify ball 1 orientation, pad dimensions, solder-mask definition, and the treatment of any central ground or exposed connection. Because the package is only 5.35 mm by 4.09 mm with 117 balls, a small dimensional error can create bridged joints or open connections.
Separate sensitive analog audio routing from digital SLIMbus clocks and switching-node areas. Keep microphone and line-level inputs short where practical, maintain a continuous ground reference, and follow the manufacturer's recommended component placement. The supplied data does not include the complete reference layout, so trace widths, spacing, return paths, and component values must be taken from the official design documentation rather than inferred.
Do not treat a generic audio codec as a drop-in substitute for the WM8998ECS/R. A valid replacement must match the 117-WCSP footprint, ball assignments, SLIMbus interface, supply rails, clocking, and device-specific control registers. The supplied cross-reference results did not identify a qualified drop-in part. Requiring a manufacturer footprint comparison and software-register review avoids a superficially similar but electrically incompatible redesign.
Confirm the permitted digital and analog supply ranges, power-up sequence, and decoupling network in the manufacturer datasheet before layout. The verified distributor data provides no voltage or current specifications, so selecting regulators, bulk capacitors, and local ceramic capacitors from generic codec values would risk instability or damage. Use the manufacturer reference schematic as the controlled baseline for rail values and power sequencing.
Plan inspection and test access for a fine-pitch 117-ball device. Optical inspection may be insufficient for hidden joints, so the assembly process may require X-ray inspection or equivalent controls. Evaluate whether the board supports repair or whether a known-good assembly stage should be used instead of reworking this package. Also verify the supplier's handling and moisture-protection requirements before accepting delivery.
Informações de conformidade
