Product details
Overview
SIO1007-JV from Microchip Technology is a 3.3V LPC Super I/O controller with ACPI 1.0 and PC99a compliance, integrating one 16C550A-compatible UART (16-byte FIFO, up to 460 kbps), dual infrared interfaces (IrDA v1.2 Fast IR, HPSIR, ASKIR, NEC PPM/RC5), 16 GPIOs, LPC PortSwitch docking interface, and intelligent auto power management - deployed in legacy industrial PCs and embedded systems requiring hot-dockable peripheral expansion.
For engineers reviewing the SIO1007-JV datasheet, SIO1007-JV pinout, SIO1007-JV application, or SIO1007-JV equivalent, key selection considerations include LPC bus timing (19.2–33 MHz), serial IRQ compatibility with PCI nCLKRUN, IO_PME#/IO_SMI# wake event support, and STQFP-64 package constraints for legacy motherboard integration.
Technical Context
The SIO1007-JV implements a dual-LPC architecture: primary host interface with multiplexed command/address/data bus and secondary switchable docking interface (3.3V only) featuring trusted cycle blocking and buffered 14 MHz output. It supports serialized IRQ, PCI nCLKRUN signaling, and relocatable configuration registers across 192 I/O address options.
Its serial subsystem includes two independent UART controllers: UART1 is a full 16C550A-compatible port with modem control; UART2 serves as an infrared communications controller supporting three IR ports - two IrDA v1.2 (4 Mbps), HPSIR, ASKIR, plus one Consumer IR port with NEC PPM/RC5 decoding and PME wake-up capability.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Super I/O controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Winbond W83627DHG-P | Integrated hardware monitor (temperature/voltage/fan), no LPC PortSwitch, single IR port (IrDA only), 128-pin LQFP. | Lacks hot-dockable LPC interface and Consumer IR decode; suited for desktop motherboards with thermal monitoring needs. | Select when system-level health monitoring outweighs docking flexibility and IR protocol breadth. |
| Nuvoton NCT6776D | Supports LPC 1.1, integrated watchdog timer, 10-bit ADC, no Consumer IR support, 128-pin LQFP. | Offers enhanced power management but omits NEC/RC5 decoding and PME-capable CIR port required for remote wake. | Prefer for newer embedded designs needing voltage sensing and watchdog reliability over legacy IR compatibility. |
Compared with Winbond W83627DHG-P and Nuvoton NCT6776D, the SIO1007-JV uniquely delivers LPC PortSwitch docking, dual IR protocol stacks (Fast IR + Consumer IR with PME), and 64-pin STQFP footprint - making it irreplaceable for space-constrained, hot-plug industrial systems requiring multi-standard infrared interoperability.

FAQ
What is the primary function of the SIO1007-JV in a system architecture?
The SIO1007-JV serves as a legacy LPC Super I/O controller that consolidates UART, infrared, GPIO, and power management functions onto a single chip. It interfaces with the host chipset via the Low Pin Count bus and provides essential I/O services for industrial PCs and embedded systems. The SIO1007-JV enables system designers to reduce component count while maintaining compatibility with Windows '9x through XP and ACPI 1.0 standards.
Does the SIO1007-JV support hot-docking functionality, and how is it implemented?
Yes, the SIO1007-JV implements hot-docking via its dedicated LPC PortSwitch interface - a secondary, switchable LPC bus with trusted cycle blocking and buffered 14 MHz output. This allows safe attachment/detachment of docking peripherals without resetting the host or violating memory protection boundaries. The SIO1007-JV manages all timing, arbitration, and isolation logic internally, eliminating need for external glue logic in dockable systems.
What infrared protocols does the SIO1007-JV support, and which pins are used?
The SIO1007-JV supports IrDA v1.2 (4 Mbps), HPSIR, ASKIR, NEC PPM, and RC5 protocols across three IR ports. IRTX2/IRRX2 handle Fast IR communication; IRRX3* supports alternate IR formats; CIRTX/CIRRX provide dedicated Consumer IR with hardware NEC/RC5 decode and PME wake capability. All IR functions are fully integrated - no external transceivers required for basic operation.
Is the SIO1007-JV pin-compatible with other Microchip Super I/O devices like the SIO1000 series?
No, the SIO1007-JV is not pin-compatible with earlier SIO1000-series devices. It uses a unique 64-pin STQFP footprint optimized for LPC PortSwitch routing and IR signal integrity, differing in pin assignment, power domains, and LPC bus multiplexing scheme. Migration requires PCB layout revision and firmware adaptation due to register map differences and enhanced IR feature set in the SIO1007-JV.
What power supply requirements and tolerance specifications apply to the SIO1007-JV?
The SIO1007-JV operates from a nominal 3.3 V supply with 5 V tolerance on I/O pins - enabling direct interfacing with legacy 5 V peripherals without level shifters. Core logic runs at 3.3 V ±10%, and the device incorporates internal power-on reset and brown-out detection. The SIO1007-JV meets RoHS compliance and halogen-free standards per IEC61249-2-21, with operating temperature range of 0°C to 70°C.
