CS5535 概要
A south bridge is a system-controller component that sits between the processor-facing north bridge and peripheral devices. It provides platform-level control and interfaces for functions such as USB, storage connectivity, input/output expansion, and system integration. In the CS5535 architecture, the device is therefore a multifunction companion rather than the principal processor, and board designers must consider the complete chipset, firmware, operating-system support, and signal-integrity requirements.
The most concrete verified feature is four-port USB support with two independent controllers. Each controller manages two ports, allowing a system to partition USB traffic across two controller domains rather than relying on one shared controller. The AMD data-book search result expressly describes this arrangement as improving enhanced-system performance, although detailed electrical limits, transfer rates, and port-routing rules require the official AMD data book.
The 208-PBGA package is a major implementation constraint. PBGA interconnects are hidden beneath the device and depend on PCB pad design, solder mask, stencil, reflow profile, and adequate escape routing. The listed package dimensions and pin count make CS5535 unsuitable for a conventional through-hole or simple two-layer redesign unless the original board infrastructure and manufacturing process are already available.
Typical CS5535 use cases include digital set-top boxes, personal-access appliances, and other embedded information appliances identified in the archived Geode material. These systems benefit from a highly integrated companion device when board area, USB connectivity, and processor-platform compatibility are priorities. Designers should not substitute a generic I/O controller without validating the north-bridge interface, pinout, firmware, interrupt behavior, USB topology, and electrical requirements.
A practical design decision is to preserve the original CS5535 footprint and validate the complete platform before changing component sourcing. The available verified sources provide the package, USB architecture, product class, and a distributor price reference, but they do not provide a complete verified pinout, timing table, electrical limit table, or approved drop-in replacement. This page distinguishes those known facts from parameters that still require manufacturer documentation.

Digital Set-Top Box Platform
The CS5535 fits a digital set-top-box design that requires a Geode-compatible companion device and four USB ports. The verified AMD material identifies digital set-top boxes as a target application, while the device's two independent USB controllers distribute two ports to USBC1 and two to USBC2. In a set-top-box board, the part can organize peripheral connectivity around an integrated processor north bridge rather than acting as a stand-alone USB bridge. The 208-PBGA package and 23 x 23 mm body size make PCB layout and thermal validation essential. Firmware support, storage connectivity, connector standards, and the exact processor platform must be verified in the AMD data book before production release.
おすすめ
Personal Access Appliance
The CS5535 is suitable for a personal-access appliance when the system retains a compatible Geode north-bridge and needs integrated peripheral control. Its four USB ports provide a practical expansion path for keyboards, storage, authentication devices, or service interfaces, while USBC1 and USBC2 provide two controller domains. The design should treat the CS5535 as a system-level south bridge, not only a USB component. Because the available verified sources do not specify operating temperature, supply voltage, or complete peripheral mapping, engineering validation must use the AMD data book and the original platform reference design. PCB escape routing for 208 PBGA balls should also be planned early.
おすすめ
Information Appliance Main Board
The CS5535 can serve as the central I/O companion in a Geode-based information appliance where board area and peripheral integration are priorities. The verified AMD description identifies the CS5535 as part of a system-level solution for information appliances, and its two USB controllers provide four total ports. This makes it useful where multiple external peripherals must be supported without adding a separate USB controller. Integration still depends on processor-platform compatibility, firmware, storage and display requirements, and the exact 208-PBGA land pattern. Do not assume that a similarly named modern companion device is interchangeable; compare the original data-book interface and pin assignments.
おすすめ
USB Peripheral Expansion
The CS5535 supports a system design needing four USB ports with two independent controllers. Each controller is assigned two ports, allowing the platform to partition peripheral functions across USBC1 and USBC2. That arrangement can improve organization compared with connecting every device to one controller, particularly in appliances that mix storage, input, service, or peripheral traffic. The verified material does not state the USB generation or per-port electrical limits, so the design team must confirm those values in the AMD data book. Cable routing, ESD protection, connector power budgeting, and platform firmware support remain separate engineering requirements and should not be inferred from the four-port count alone.
おすすめ
Embedded Access and Control Terminal
The CS5535 can support an embedded access or control terminal built around a Geode-class platform that needs integrated USB connectivity. Two USB controller domains provide a way to separate device classes, and the four-port total can support peripheral combinations such as a local interface, service connection, reader, or storage device. The device should be selected only when the original system controller and firmware expect the CS5535 companion architecture. Because the verified data does not enumerate the complete peripheral map or USB timing limits, engineers should use the AMD data book to confirm pin assignments, interrupts, power states, and controller sharing. The PBGA footprint also requires a manufacturing-capable PCB layout.
おすすめ
Legacy Geode Platform Maintenance
The CS5535 is most relevant to maintenance of an existing Geode-based product rather than a new generic embedded design. Keeping the original companion device can preserve platform firmware, processor-interface compatibility, and peripheral behavior when the board already uses its 208-PBGA footprint. The verified AMD material specifically associates the device with Geode GX2 processor-series north-bridge solutions. Before stocking replacements, verify the exact package suffix, ballout, revision behavior, operating temperature, and lifecycle status. No verified drop-in equivalent was found, so maintenance planning should account for sourcing risk and board-specific validation.

設計ノート
CS5535 uses a 208-PBGA package, so preserve the original AMD land pattern and verify escape routing before layout release. PBGA balls are not accessible with a conventional through-hole footprint; pad geometry, solder-mask definition, stencil aperture, reflow profile, and assembly inspection must follow the package documentation. Do not substitute a generic BGA or QFP footprint based only on the 23 x 23 mm body dimension.
Do not treat a generic multifunction south bridge as a CS5535 drop-in replacement. Compatibility requires the Geode processor/north-bridge interface, exact 208-ball pinout, electrical limits, firmware behavior, USB topology, and PCB footprint to match. The supplied search results identify no verified pin-compatible substitute, so any alternate part should begin with a manufacturer cross-reference and a complete platform validation plan.
The verified sources do not provide the CS5535 supply-voltage range, current limits, power states, or thermal resistance. Before power budgeting, obtain those values from the AMD data book and the original platform schematic. Confirm regulator headroom, sequencing, USB port power budgeting, and local decoupling against the exact device revision rather than estimating from the package size or system power demand.
Plan USB routing as a complete platform subsystem. Keep controller-to-connector paths short, preserve the intended USBC1/USBC2 partitioning, and follow the AMD reference layout for impedance, protection, and return paths. Add external ESD and surge protection where required by the system specification, then validate signal integrity with the selected connector, cable, and enclosure. The verified sources do not specify USB speed or trace impedance.
Commercial listings identify CS5535 inventory and a $14.796 starting price, but they do not guarantee production continuity, exact suffix equivalence, or a fixed lead time. Confirm the ordering code, package revision, condition, quantity, and region with the seller. For maintenance builds, preserve traceability because a similar package name does not guarantee a matching ballout or firmware-compatible device.
コンプライアンス情報
The supplied verified results do not state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification status. AEC-Q100 is marked not applicable because CS5535 is an information-appliance and system I/O companion rather than an automotive-qualified device in the provided data.
