SCH5627P

Desktop Embedded Controller with Fan Control,

Hardware Monitoring and PECI

• Temperature Monitor

Highlights

- Monitoring up to 2 Remote Thermal Diodes

plus an Anti-Parallel Remote Thermal Diode

• High Performance Embedded Controller (EC)

• ACPI 2.0 Compliant

- Built-in ADC supports temperature readings

from -63 degrees Celsius to +192 degrees

Celsius

• PC2001 Compliant

• LPC Interface

- Supports LPC Bus frequencies of 19MHz to

33MHz

–Supports monitoring of discrete diodes (3904 type

diodes)

–Supports monitoring substrate diodes (45nm &

65nm processor diodes)

- Multiplexed Command, Address and Data

Bus

- Temperature resolution is 0.125 degrees Cel-

sius

- Serial IRQ Interface Compatible with Serial-

ized IRQ Support for PCI Systems

- Internal Ambient Temperature Measurement

- Out-of-limit Temperature Event reporting

• Bi-directional PROCHOT# Pin

- PME Interface

• 3.3-Volt I/O

• 128-pin QFP RoHS Compliant Package

• System Watch Dog Timer (WDT)

• Battery Backed Resources

- Power-Fail Status Register

- VBat backed 64 byte memory

• Extreme Low S5

- Interrupt generation for PROCHOT Assert

events

- May be used by AMTA and PTTA features to

adjust fan control limits

- May be configured to force fans on full

- Supports PROCHOT Assertions to external

CPU

- Enables power saving by shutting down

standby voltage regulators in system S5 state

- Supports PROCHOT Throttle Events to

external CPU

- System wake from power button press

- System wake from LAN

- Supports Interrupt Event to Host

• Voltage Monitor

• Two EC-based SMBus 2.0 Host Controllers

- Allows Master or Dual Slave Operation

- Monitoring VBAT, VTR,VCC and Vtt power

supplies

- Controllers are Fully Operational on Standby

Power

- DMA-driven I²C Network Layer

- I²C Datalink Compatibility Mode

- Multi-Master Capable

- Monitoring of one external voltage

- Limit comparison on monitored values

• PWM (Pulse width Modulation) Outputs (4)

- Multiple Clock Rates

- Supports Clock Stretching

- Programmable Bus Speeds

- 400 KHz Capable

- 16-bit ON and 16-bit OFF Counters

• Fan tachometer Inputs (4)

- Programmable to monitor standard tachome-

ter outputs or locked rotor alarm outputs

- Hardware Bus Access “Fairness” Interface

- Detects SMBus Time-outs

- Generate tachometer event when speed of

fan drops below programmed limit

- One controller can be multiplexed onto a low

voltage SMBus

• Internal clock sources

• PECI Interface 2.0

- A Ring Oscillator generates 64 MHz clock

- Supports PECI REQUEST# and PECI

READY signaling

- SIO clocks derived from a 96MHz PLL syn-

chronized to a 14.318MHz clock input

- Supports up to 2 CPUs and 4 domains

• Temperature reading from PCH over SMBus

• Temperature reading from AMD-TSI over SMBus

- Main ring generates 32kHz standby clock

when external 32.768KHz clock source is off

• Low Battery Warning
