based on temperature

Product Features

• ACPI 2.0 Compliant

• High Performance 8051

- Acoustic enhancement mode

- ProcHot pins modulate Tmin

- Fan PWM duty cycle is a function in linear

mode of multiple temperatures and ProcHot

signals

- PWM Ramp Rate Closed Loop Control

• Internal Ring Oscillator for VTR Powered Logic

• Low Battery Warning

- 2.5X average instruction execution speed

improvement over the entire instruction set;

i.e., typical 4-clock instruction cycle in high-

performance 8051 vs. 12-clock instruction

cycle in standard 8051.

- Faster clock speed: 32 MHz vs. 16 MHz in

standard 8051.

- Dual Data Pointers

• LED Control

- More Interrupts: Power-Fail, External Inter-

rupt 2, External Interrupt 3, etc.

trolled, 16 8051 controlled)

• 21 Dedicated Scratchpad registers

• ISA Plug-and-Play Compatible Register Set

• System Management Interrupt

• GLUE Logic

- Twelve Interrupt Sources

- Watch Dog Timer (WDT)

• Operating Temperature Range of 0^oC to +70^oC

- IDE Reset/Buffered PCI Reset Outputs

- Power OK Signal Generation

- Power Sequencing

- Power Supply Turn On Circuitry

- Resume Reset Signal Generation

- Hard Drive Front Panel LED

• 2.88MB Super I/O Floppy Disk Controller

- Licensed CMOS 765B Floppy Disk Controller

- Software and Register Compatible with

Microchip's Proprietary 82077AA Compatible

Core

• PECI Interface

65nm processor diodes)

- 1/8th degree temperature resolution

- Internal Ambient Temperature Measurement

- Limit Comparison of all Monitored Values

• PROCHOT_IN# Pin

- Mapped into Temperature monitoring inter-

rupt generation logic

- May be used to adjust fan control limits

- May be configured to force fans on full

• PROCHOT_OUT Pin

- 100% IBM® Compatibility

- Detects All Overrun and Underrun Conditions

- Sophisticated Power Control Circuitry (PCC)

Including Multiple Powerdown Modes for

Reduced Power Consumption
