KSZ9692PB

Application Specific Microcontrollers Overview

The KSZ9692PB is a System-on-Chip integrating an ARM922T processor running at 250 MHz with two Gigabit Ethernet MACs, dual USB 2.0 ports, and a PCI 2.3 interface. It features a DDR controller supporting up to 200 MHz clock frequencies and an SDIO/SD host controller. The device includes four high-speed UARTs, GPIOs, timers, and DMA controllers for dedicated data transfer channels. Operating voltages include 1.3V for the core, 3.3V for I/O, and 2.5V or 2.6V for the DDR memory interface.

Application Specific Microcontrollers Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors. Confirm package integrity and check for moisture sensitivity indicators prior to installation. Review the latest datasheet revision history for any operational updates or errata sheets applicable to this specific silicon revision.

Application Specific Microcontrollers Selection Notes

Select the KSZ9692PB when an integrated SDIO/SD Host Controller is required, as this feature is exclusive to the PB variant compared to the XPB model. Ensure the design supports the specified operating voltage requirements of 1.3V for the core and 3.3V for I/O. Verify that the application utilizes the PCI arbiter capacity for up to three external masters.

Application Specific Microcontrollers Part Context

This component belongs to the KSZ9692 family of integrated networking controllers. It serves as a high-performance embedded application controller designed for cost-sensitive, high-bandwidth applications. The PB suffix specifically denotes the inclusion of the SDIO/SD Host Controller peripheral not present in the XPB counterpart.

Application Specific Microcontrollers Replacement Considerations

The KSZ9692XPB is a related variant within the same family but lacks the integrated SDIO/SD Host Controller. Substitution requires verifying if the SDIO functionality is necessary for the target application.
