SIO1000-JV

Specialized Overview

The SIO1000-JV is an I/O Controller Interface IC featuring an LPC Super I/O architecture. It operates at 3.3 Volts with 5V tolerance and supports ACPI 2.0 compliance alongside PC99a and PC2001 standards. The device integrates a full-function serial port with a high-speed 16C550A compatible UART, supporting baud rates up to 460k. It includes a multi-mode parallel port with ChiProtect circuitry for EPP and ECP compatibility. Additional features include 14 GPIOs, two IRQ input pins, programmable wakeup events via the IO_PME# pin, and SMI support through the IO_SMI# pin. The component is housed in a 64-pin STQFP package.

Specialized Feature Summary

• Supports intelligent auto power management and programmable wakeup events
• Integrates a high-speed UART with 16-byte FIFO and modem control circuitry
• Includes a multi-mode parallel port with enhanced capabilities and protection circuitry
• Provides consumer IR and FIR interface support via LPC bus

Specialized Applications

• LPC Media Center systems requiring Consumer IR controller functionality
• Systems needing Windows Vista remote control support integration
• General purpose Super I/O applications requiring ACPI 2.0 compliance

Specialized Procurement Notes

Verify the manufacturer origin as SMSC Corporation or Microchip Technology, as documentation sources vary. Confirm the specific suffix JV indicates the required package and temperature range. Ensure the datasheet matches the LPC interface and FIR/Consumer IR support requirements. Check for RoHS compliance status if environmental regulations apply to the target assembly process.

Specialized Selection Notes

Select this component when an LPC-based Super I/O solution is required with integrated infrared capabilities. It is suitable for designs needing a single chip to handle serial, parallel, and GPIO functions while maintaining ACPI 2.0 standards. Consider the 64-pin STQFP package constraints during PCB layout planning. Verify that the 3.3V operation aligns with the system's core voltage levels.

Specialized Part Context

The SIO1000-JV belongs to the SIO 1000 series of Super I/O controllers. It is functionally related to the SIO 1049, which also targets media center applications with similar LPC and Consumer IR interfaces. Both devices address the need for integrated I/O management in legacy-compatible modern systems.

Specialized Replacement Considerations

The SIO 1049 serves as a functional substitute for media center applications due to shared LPC and Consumer IR features. Verify pinout compatibility and software driver support before substitution.
