Product details
Overview
KSZ9692XPB from Microchip Technology is a highly-integrated ARM922T-based SoC networking controller featuring a 250 MHz processor core, dual 10/100/1000 Mbps Ethernet MACs with MII/RGMII support, PCI 2.3 interface (single external master), and 32-bit DDR memory controller - designed for residential gateways and VoIP systems requiring embedded networking and communications processing.
For engineers reviewing the KSZ9692XPB datasheet, KSZ9692XPB pinout, KSZ9692XPB application, or KSZ9692XPB equivalent, key selection criteria include its single-master PCI configuration, absence of SDIO host controller, DDR clock driver integration, 1.3V core voltage, and dedicated DMA channels for Ethernet, USB, and PCI.
Technical Context
The KSZ9692XPB implements an ARM922T RISC core operating at up to 250 MHz with 8KB I-cache and 8KB D-cache, coupled to a 166 MHz AMBA AHB bus. Its memory subsystem includes a 32-bit DDR controller (200 MHz clock, 400 Mbps data rate) with two integrated JESD82-1-compliant differential clock drivers and a NAND flash interface supporting 512+16 and 2048+64 byte page sizes.
Networking functionality centers on two IEEE 802.3-compliant Gigabit Ethernet MACs - Port 0 (WAN) supports up to 2000-byte frames and 8KB TX/RX FIFOs; Port 1 (LAN) supports up to 9KB frames and 24KB RX/22KB TX FIFOs - with hardware IPv4/IPv6 TCP/UDP checksum offload, 32-rule ACL filtering, and Wake-on-LAN including Magic Packet detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Processor Core | ARM922T RISC, 250 MHz max - enables Linux/WinCE OS support via configurable MMU and cache hierarchy. |
| Ethernet Interfaces | Dual 10/100/1000 Mbps MACs with MII/RGMII - provides WAN/LAN separation with independent 8KB/24KB receive FIFOs for burst traffic resilience. |
| PCI Interface | PCI 2.3, 32-bit/33–66 MHz, one external master - simplifies integration with legacy mini-PCI peripherals without requiring external arbiter logic. |
| DDR Memory Controller | 32-bit, 200 MHz clock (400 Mbps), two integrated SSTL_2 clock drivers - enables glueless DDR interface with JEDEC-compliant timing and up to 128 MB addressable space. |
| USB Interface | Dual USB 2.0 ports with integrated PHY - supports 2-port host or host+device configurations with dedicated DMA per port for high-throughput data transfer. |
| Power Supply | 1.3V core / 3.3V I/O / 2.5–2.6V DDR - mandates separate LDO regulation domains and impacts PCB power delivery layout. |
| Peripheral Set | Four UARTs (up to 5 Mbps), two 32-bit timers (one with watchdog), 20 GPIO, I²C/SPI/I²S, interrupt controller - supports console, timing, sensor, audio, and control functions in compact designs. |
Pinout & Package
The KSZ9692XPB is housed in a 484-pin PBGA package (27 mm × 27 mm, 1.0 mm pitch) with ball map defined in Microchip DS00003073A, pages 43–44. Pin assignments are functionally grouped into DDR, PCI, Ethernet MII/RGMII, USB, UART, and power domains, with dedicated VDD_DDR, VDD_IO, and VDD_CORE supply balls.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DDR_CLK_P / DDR_CLK_N | Differential DDR clock output | Drives DDR SDRAM clock tree directly - eliminates need for external clock buffer in compliant layouts. |
| PCI_AD[31:0] | PCI address/data multiplexed bus | Carries 32-bit address and data cycles - requires proper PCI termination and timing compliance for 66 MHz operation. |
| ETH0_RXD[3:0] / ETH0_TXD[3:0] | RGMII data interface (Port 0) | Supports 1000 Mbps operation with source-synchronous timing - demands matched trace lengths and controlled impedance. |
| USB_DP0 / USB_DM0 | USB 2.0 differential pair (Port 0) | Integrated 45 Ω termination and 1.5 kΩ pull-up - reduces BOM count and layout complexity for full-speed/high-speed signaling. |
| VDD_CORE | 1.3V processor core supply | Requires low-noise, high-PSRR regulation - decoupling must be placed near corresponding balls to minimize IR drop. |
| GPIO[19:0] | General-purpose I/O bank | Individually configurable as input/output/alternate function - includes UART CTS/RTS, timer outputs, and external interrupt inputs. |
Key Features
| Feature | Design Value |
|---|---|
| ARM922T + MMU + caches | Enables full Linux kernel execution with memory protection and deterministic real-time response for network stack processing. |
| Dual Ethernet MACs with hardware checksum offload | Reduces CPU load by >30% during IPv4/IPv6 TCP/UDP packet processing - critical for concurrent VoIP and routing tasks. |
| Integrated DDR clock drivers | Eliminates external clock buffer IC and associated layout constraints - lowers BOM cost and improves signal integrity margin. |
| Single-master PCI arbiter | Simplifies system-level arbitration logic versus KSZ9692PB's three-master design - reduces FPGA or companion chip requirements. |
| Wake-on-LAN with Magic Packet detection | Allows complete system power-down while maintaining network presence - extends energy efficiency in always-on residential gateways. |
| Dedicated DMA per Ethernet/USB/PCI | Enables zero-copy data movement between peripherals and DDR - avoids CPU bottlenecks during sustained 1 Gbps throughput. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar embedded networking controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| KSZ9692PB | Includes SDIO/SD host controller and three-master PCI arbiter; otherwise identical core, Ethernet, DDR, and USB specs. | Required for designs needing removable storage or multi-peripheral PCI expansion (e.g., dual Wi-Fi radios). | Select KSZ9692PB only if SDIO or multi-master PCI is mandatory; KSZ9692XPB reduces cost and complexity where those features are unused. |
| MPC8360E | Power Architecture e300 core (333–667 MHz), single Gigabit Ethernet, no integrated DDR clock drivers, different peripheral set. | Better suited for legacy PowerPC toolchain environments and single-port routing with external DDR clocking. | Choose MPC8360E when migrating from existing PowerPC designs or when DDR clock buffer integration is not required. |
Compared with KSZ9692PB, the KSZ9692XPB removes SDIO and reduces PCI arbitration capability - lowering cost and power for fixed-function gateways. Versus MPC8360E, it offers higher integration (dual Ethernet, DDR clocks, USB PHY) but requires ARM toolchains and lacks PowerPC ecosystem support.

FAQ
What distinguishes KSZ9692XPB from KSZ9692PB?
The KSZ9692XPB omits the SDIO/SD host controller and implements a single-master PCI arbiter, whereas the KSZ9692PB includes both SDIO support and a three-master PCI arbiter. All other core features - ARM922T processor, dual Ethernet MACs, DDR controller, USB 2.0, and peripheral set - are identical between the two variants. This makes KSZ9692XPB optimal for designs that do not require removable storage or complex PCI expansion.
Does KSZ9692XPB support hardware-accelerated IPv6 packet processing?
Yes, KSZ9692XPB supports hardware generation of IPv6 TCP/UDP checksums and detection of IPv6 TCP/UDP checksum errors in both LAN and WAN MAC paths. It also enables up to eight IP-based filtering rules in its Access Control List engine for IPv6 traffic, reducing host CPU overhead during protocol inspection.
What DDR memory configurations are supported by KSZ9692XPB?
KSZ9692XPB supports 32-bit DDR SDRAM with densities up to 1 Gb, using x8 or x16 device widths. It provides two integrated JESD82-1-compliant differential clock drivers, SSTL_2 I/Os, and configurable RAS/CAS timing parameters. Addressable space reaches 128 MB with 12-column and 14-row addressing.
Can KSZ9692XPB operate in both MII and RGMII modes simultaneously on its Ethernet ports?
No, each Ethernet port (Port 0 and Port 1) is independently configurable for either MII or RGMII interface mode via strap pins or register settings, but both ports cannot operate in different modes concurrently. The choice is fixed per port at boot time and affects pin assignment and timing requirements.
Is there hardware support for Wake-on-LAN features in KSZ9692XPB?
Yes, KSZ9692XPB includes full hardware Wake-on-LAN support, including Magic Packet detection, link status change wake events, and user-defined wake-up frame matching (up to four per port). These features operate while the ARM core and most peripherals are powered down, enabling ultra-low-power standby in residential gateway applications.
