Microchip Technology KSZ8695P

KSZ8695P targets integrated broadband and small-office gateways. Its five Fast Ethernet transceivers and MACs provide one WAN port and four LAN switch ports, while the ARM9 core executes gateway software. The PCI and external-memory interfaces permit system expansion without a separate CPU-plus-switch architecture.

The manufacturer specifies a 289-pin plastic ball-grid array (PBGA), 19 mm × 19 mm, for KSZ8695P. The existing product and workbook registry use the generic name “289-BGA” (registered row 847); preserve that catalog label while checking pitch, ball map, and land pattern against the PBGA drawing before layout. Generic 289-ball packages are not automatically interchangeable.

Layout checks

• Confirm 19 mm PBGA body and complete ball map.
• Route 1.8 V core/RX and 3.3 V I/O/TX supplies separately as specified.
• Place Ethernet magnetics, clock, reset, and decoupling per the reference design.
• Check PCI and memory timing before finalizing board layers.

The local registered JPG is absent and the production JPG returns HTTP 404. This package visual is not currently verified, so publication is blocked.

The 289-ball interface groups Ethernet, PCI, external memory, power, clock, reset, debug, and general-purpose signals. Use the exact manufacturer ball table, not an inferred generic BGA pinout.

The data sheet's revision history includes pin-definition corrections; verify the latest ball map and board design before assembly.

Values summarize the Rev. 1.5 data sheet. Check full operating ratings, pin limits, timing, and application circuits before design use.

Do not substitute KSZ8695PI or a later gateway SoC solely by package. The industrial PI suffix has a different temperature grade; alternatives also require comparison of the 289-ball map, clock/reset behavior, Ethernet interfaces, PCI function, memory map, power domains, and firmware. No internal alternative product is linked because exact API-confirmed compatibility was not established.

The KS8695P platform was documented by Micrel; its manufacturer data sheet is available from Microchip Technology. The ordering table explicitly pairs standard KS8695P with lead-free KSZ8695P in the 289-pin PBGA and specifies 0°C to +70°C for this commercial code.

Confirm the full KSZ8695P marking, package condition, ball integrity, lot traceability, and ESD handling. Compare received devices and PCB footprint with the manufacturer's PBGA information. Treat the commercial and industrial suffixes as distinct orderable grades.

Use the manufacturer's latest hardware and software references to validate clocks, reset, power sequencing, PHY magnetics, memory and PCI timing, software support, and thermal behavior. The catalog's generic “289-BGA” designation must be checked against the precise 289-pin PBGA drawing; the registered package JPG is unavailable on the production site. Keep this page unpublished until those checks pass.
