SIO1007-JV

Specialized Overview

The SIO1007-JV is a Super I/O controller operating at 3.3V with 5V tolerance, housed in a 64-pin STQFP package. It features an LPC bus interface supporting frequencies from 19.2MHz to 33MHz and includes an LPC PortSwitch for hot-docking. The device integrates two UARTs: one 16C550A-compatible serial port with 16-byte FIFOs and a second infrared communications controller supporting IrDA v1.2, HPSIR, ASKIR, NEC PPM, and RC5 protocols. System resources include 16 GPIOs, three DMA channels, and support for ACPI 1.0 compliance.

Specialized Feature Summary

• LPC Bus Host Interface with PortSwitch capability for docking applications
• Dual Serial Ports including a 16C550A compatible UART and Infrared Controller
• Integrated Power Management Circuitry with Wakeup Event Interface
• Software Configurable Logic for flexible system configuration

Specialized Applications

• Hot-swappable external docking stations
• Consumer IR remote control interfaces
• Legacy PC peripheral interfacing
• Industrial embedded systems requiring serial communication

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product selector to confirm packaging options. The standard designation indicates tray packaging, while tape and reel availability requires explicit confirmation through authorized sales channels or distributor catalogs prior to procurement planning.

Specialized Selection Notes

Select this component when designing systems requiring legacy ISA Plug-and-Play compatibility alongside modern LPC bus connectivity. Ensure the design accommodates the 3.3V logic levels and utilizes the available GPIOs for custom signal routing. Verify that the target application supports the required ACPI version and infrared protocol standards defined in the specifications.

Specialized Part Context

This part belongs to the Microchip SIO1007 family of Super I/O controllers. It succeeds earlier SMSC designs within the same functional lineage. The device provides a consolidated solution for managing serial, infrared, and general-purpose I/O functions in compact form factors suitable for portable and desktop computing platforms.

Specialized Replacement Considerations

Check for updated revisions of the SIO1007 series. No direct pin-to-pin substitutes are documented in the provided source material. Evaluate alternative Super I/O controllers if the LPC PortSwitch feature is not required.
