KSZ8692XPB

Application Specific Microcontrollers Overview

The KSZ8692XPB is a System-on-Chip networking controller featuring an ARM922T processor core operating at 250 MHz. It integrates two 10/100 Mbps Ethernet MACs, dual USB 2.0 interfaces, and a PCI 2.3 interface supporting one external master. The device includes a 32-bit DDR controller with integrated differential clock drivers, static memory controllers for FLASH/ROM/SRAM, and a NAND flash controller. Power specifications require a 1.3 V core supply and 3.3 V I/O supply. The component is housed in a 400-pin PBGA package and operates within a commercial temperature range of 0°C to +70°C.

Application Specific Microcontrollers Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors. Confirm the specific ordering suffix matches the required pin configuration and boot options. Check current lifecycle status as this model may be subject to discontinuation notices. Ensure compatibility with existing PCB layouts regarding the 400-pin PBGA footprint and power sequencing requirements.

Application Specific Microcontrollers Selection Notes

Select the KSZ8692XPB over the KSZ8692MPB variant when only one PCI external master is required and SDIO functionality is not needed. Evaluate system memory requirements against the supported 32-bit DDR controller capabilities. Ensure the application environment remains within the 0°C to +70°C commercial operating temperature range. Verify that the host architecture supports the ARM922T instruction set and MMU configuration.

Application Specific Microcontrollers Part Context

This component belongs to the KSZ8692 series of integrated networking controllers originally developed by Micrel, Inc., which was subsequently acquired by Microchip Technology. The datasheet revision history indicates updates to DDR data width configurations from 16-bit to 32-bit. The XPB designation specifically denotes the variant optimized for single-master PCI applications without SDIO support.
