PC87365 Datasheet | National Semiconductor

Description The PC87365, a member of National Semiconductor’s 128pin LPC Super I/O family, features National’s new System Hardware Monitoring capability. The PC87365 is PC99 and ACPI pliant, and offers a single-chip solution to the most monly used PC I/O peripherals. System Hardware Monitoring provides minimum power consumption and maximum operating efficiency within the system environment. It integrates National’s Voltage Level Monitor (VLM) which monitors system voltages using 8-bit Analog to Digital (A/D) conversion, seven analog input channels and VREF input, and National’s diode input Temperature Sensor for full, PC system thermal control. The PC87365 also incorporates: Fan Speed Control and Monitor (FSCM) for three fans, extended wake-up support for a wide range of wake-up events, system design protection features , a Floppy Disk Controller (FDC), a Keyboard and Mouse Controller (KBC), ACCESS.bus® Interface (ACB), System Wake-Up Control (SWC), General-Purpose Input/Output (GPIO) support for 40 ports, Interrupt Serializer for Parallel IRQs, an enhanced WATCHDOG Timer (WDT), a full IEEE 1284 Parallel Port and two enhanced Serial Ports (UARTs), one with Infrared (IR) support. Outstanding Features q System Hardware Monitoring including: - Diode-based Temperature Sensor (TMS) - Voltage Level Monitor (VLM) with VID inputs Extended Wake-Up support, including legacy/ACPI power button support, direct power supply control in response to wake-up events, power-fail recovery Protection features , including I/O access lock, chassis hood lock/unlock, chassis intrusion detection, GPIO lock and pin configuration lock Fan Speed Control and Monitor for three fans Serial IRQ support (15 options) Interrupt Serializer (11 Parallel IRQs to Serial IRQ) Bus interface, based on Intel’s LPC Interface Specification Revision 1.0, September 29th, 1997 ACCESS.bus Interface, SMbus® physical layer patible 40 GPIO Ports (29 standard, including 15 with Assert IRQ/SMI/PWUREQs interrupts; 11 VSB...
