BCM5320MKPB - 26-Port Managed Ethernet Switch | Broadcom
料号： BCM5320MKPB ✗ 停产BCM5320MKPB 概述
A managed Ethernet switch is a networking semiconductor that forwards Ethernet frames between connected devices while adding configurable control, monitoring, and traffic-management functions. In the product hierarchy, BCM5320MKPB belongs to Ethernet switches, interface ICs, and integrated circuits. Its 24 Fast Ethernet ports serve numerous access connections, while the two Gigabit Ethernet ports provide higher-bandwidth links for uplinks, aggregation, or equipment interconnection.
Key characteristics include the 26-port 100 Mbps and 1 Gbps configuration, L2+ managed-switch functionality, 400-pin BGA construction, and MSL 1 unlimited floor-life handling. The available part data identifies BCM5320MKPB as the base Broadcom BCM5320M orderable configuration, supplied in a tray. Detailed data for operating voltage, clocking, PHY media support, maximum frame size, temperature limits, and power consumption was not present in the supplied verified records.
Architecturally, the BCM5320M family combines a managed switching function with a mixed-rate Ethernet port set in one integrated circuit. This consolidation can reduce the component count and inter-device routing complexity of a managed switch design. The two 1 Gbps ports provide an upgrade path over the 24 10/100 ports, although the exact supported copper or fiber media and optional serialization interfaces require confirmation from the manufacturer datasheet before schematic and layout release.
Typical uses include industrial Ethernet switches, network-interface equipment, embedded network appliances, access concentrators, and managed connectivity products. The 24-port Fast Ethernet grouping is particularly relevant to equipment that must aggregate many 100 Mbps links, while the two Gigabit Ethernet ports can serve uplink or expansion duties. The same-port-count comparison should include management features, PHY support, timing, package balls, firmware requirements, and thermal conditions.
Design planning should begin with the complete Broadcom reference design, the 400-ball land pattern, supported copper media, and required management interfaces. Because the supplied evidence identifies a 400-pin BGA but does not provide a verified ball map, designers should not infer pin assignments from the orderable code. PCB stack-up, via-in-pad requirements, decoupling, thermal management, and high-speed layout must follow Broadcom's released design guidance.
This page consolidates the verified port configuration, package information, lifecycle-related procurement references, same-family drop-in candidates, comparison parameters, and practical sourcing guidance. It also clearly separates confirmed BCM5320MKPB data from parameters that still require manufacturer documentation, reducing the risk of designing from incomplete distributor metadata.

典型应用
BCM5320MKPB 适用于 6 应用s: Managed Industrial Ethernet Switch, Access Network Concentrator, Network Interface Appliance, Video Surveillance Network Switch, Industrial Control Cabinet Switch, Enterprise Network Edge Switch.
Managed Industrial Ethernet Switch
BCM5320MKPB fits access-heavy industrial Ethernet equipment because it provides 24 Fast Ethernet ports at 10/100 Mbps and two Gigabit Ethernet ports at 1 Gbps in one L2+ managed-switch IC. The 24 low-speed ports can serve sensors, programmable controllers, remote I/O, and operator stations, while the two higher-speed ports can support uplink traffic. Its confirmed 400-pin BGA construction allows compact switching hardware, but it also demands controlled high-speed layout. The verified data does not specify the industrial temperature range, isolated media, power consumption, or PHY variants, so those qualifications must be checked against the controlled Broadcom documentation before deployment in a factory network.
推荐
Access Network Concentrator
BCM5320MKPB is suitable for a concentrated access-node architecture that must terminate many 100 Mbps links while retaining two 1 Gbps network-facing ports. Its confirmed total capacity is 26 ports, with a clear 24-port 10/100 Mbps group and two Gigabit Ethernet positions that can serve aggregation or equipment uplinks. Using one L2+ switch device can simplify the network topology compared with a design assembled from multiple smaller switches. Before finalizing the architecture, engineers should verify supported copper media, auto-negotiation behavior, management features, maximum frame size, and thermal performance because those values were not included in the supplied verified metadata.
推荐
Network Interface Appliance
BCM5320MKPB can serve as the central Ethernet switching element in a compact network-interface appliance that combines many device connections with higher-speed backbone links. The 24 10/100 Mbps ports suit management, service, and endpoint connections, while the two 1 Gbps ports can connect the appliance to an upstream network or local storage. The L2+ managed-switch positioning permits configurable Layer 2 network behavior rather than a simple fixed forwarding function. The verified source identifies a 400-pin BGA package, so thermal vias, decoupling, reference-controlled stack-up, and signal-integrity validation are essential. Operating voltage, power, clock requirements, and software support must be obtained before schematic release.
推荐
Video Surveillance Network Switch
BCM5320MKPB can be evaluated for surveillance networks where many access endpoints connect at 10/100 Mbps and two aggregation links operate at 1 Gbps. The mixed-speed port arrangement can provide a straightforward separation between endpoint-facing 100 Mbps connections and higher-capacity recording or core-network links. Because the device is managed rather than a basic unmanaged switch, it may support configurable traffic behavior needed to segment camera traffic and management access. The verified data does not confirm IGMP behavior, QoS, packet-buffer size, ingress filtering, or the supported number of VLANs. These functions, along with operating-temperature and power specifications, must be verified from the Broadcom BCM5320M documentation before surveillance deployment.
推荐
Industrial Control Cabinet Switch
BCM5320MKPB fits the port-count requirements of a compact control-cabinet Ethernet switch, where programmable logic, HMIs, sensors, and remote equipment can occupy the 24 Fast Ethernet ports while two Gigabit Ethernet links connect to plant infrastructure. Consolidating this mixed-rate connectivity into one L2+ switch IC can reduce board area compared with multiple switch packages. The 400-pin BGA still requires careful power delivery, thermal management, and high-speed layout in a confined enclosure. The supplied data does not verify industrial-grade temperature limits, robust magnetic isolation, surge performance, or operating lifetime. Those environmental requirements should be checked against the exact Broadcom orderable device and system safety criteria before field installation.
推荐
Enterprise Network Edge Switch
BCM5320MKPB is applicable to an enterprise network-edge or access switch designed around numerous 100 Mbps endpoint links and two 1 Gbps uplink connections. The 24-plus-2 configuration provides a straightforward migration path between legacy 10/100 Mbps devices and Gigabit network infrastructure while retaining centralized Layer 2 management. Its single-chip L2+ positioning can help reduce PCB complexity and simplify synchronization of switching resources within a fixed platform. However, verified evidence for stacking, synchronization, QoS depth, VLAN scale, traffic prioritization, and management software is absent. Engineers should compare the BCM5320M feature set with the system specification and validate firmware, thermal, and recovery requirements before using it in an enterprise edge appliance.

设计说明
Do not begin the PCB footprint from the generic BGA label alone. According to the verified product records, BCM5320MKPB uses a 400-pin BGA, but the ball pitch, pad dimensions, exposed-pad arrangement, and keep-out geometry were not supplied. Download the current Broadcom package drawing and reference PCB files, then verify the land pattern against the selected orderable device. A footprint error at this scale can affect power continuity, high-speed return paths, solderability, and board yield.
The verified records do not provide BCM5320MKPB operating voltage, current, or power dissipation, so no supply or capacitor sizing should be inferred from the port count. Use the manufacturer power table for each supported media configuration, including worst-case PHY activity and startup. Plan local input and output decoupling directly from the reference schematic, provide low-impedance power planes, and include current probes or test points so measured board power can be compared with the datasheet limit before production release.
A 400-pin BGA concentrates many I/O and power connections into a compact area, making heat flow and assembly yield important design constraints. Use the manufacturer's recommended PCB stack-up, via-in-pad or thermal-via arrangement, and exposed-pad treatment. Confirm the package thermal characterization rather than estimating performance from pin count. During validation, record junction-relevant temperature through a supported method and test the highest populated-port and maximum-line-rate conditions, not only an idle board.
Follow the controlled Broadcom reference layout for clock, PHY media, management, and high-speed digital interfaces. Keep the switching device, PHY-related circuitry, magnetic interfaces, and decoupling positioned according to the released design; route clocks as controlled-length nets with continuous reference planes and minimize loop area. Avoid improvised substitutions around the 400-pin land pattern, and perform signal-integrity simulation with the actual stack-up, connector, cable, and PHY configuration used in production.
Do not treat a distributor's generic Ethernet-switch label as proof of functional interchangeability. The confirmed BCM5320MKPB arrangement is 24 10/100 Mbps ports plus two 1 Gbps ports, but media support, management behavior, pinout, firmware, and thermal limits were not fully available in the supplied records. Before using any listed same-family alternative, compare the controlled ordering table, ball map, electrical limits, PHY type, reference firmware, and qualification status. Require a written second-source approval rather than relying on package-name similarity.
合规信息
The verified GlobalSpec record states REACH Unaffected and MSL 1 (Unlimited). RoHS, lead-free, halogen-free, conflict-minerals, and AEC-Q100 status were not explicitly provided and therefore are not assumed. A network-interface IC is treated as not applicable for AEC-Q100 rather than qualified or not qualified.
