Introduction 1 Introduction The Intel® Celeron® M processor and the ultra low voltage (ULV) Intel® Celeron® M processor are high-performance, low-power mobile processors with several microarchitectural enhancements over existing mobile Intel Celeron processors. The Intel Celeron M processor is available at the following core frequencies in the Micro-FCBGA and Micro-FCPGA packaging technologies: • • • • 1.20 GHz (1.356 V) 1.30 GHz (1.356 V) 1.40 GHz (1.356 V) 1.50 GHz (1.
Introduction The new packed, double-precision, floating-point instructions enhance performance for applications that require greater range and precision, including scientific and engineering applications and advanced 3D geometry techniques, such as ray tracing. The processor’s 400-MHz FSB utilizes a split-transaction, deferred reply protocol.

Introduction 10 Intel® Celeron® M Processor Datasheet
Low Power Features 2 Low Power Features 2.1 Clock Control and Low Power States The Intel Celeron M processor supports the AutoHALT, Stop Grant, Sleep, and Deep Sleep states for optimal power management. See Figure 1 for a visual representation of the processor lowpower states. Figure 1.
Low Power Features The system can generate a STPCLK# while the processor is in the AutoHALT Power-Down state. When the system deasserts the STPCLK# interrupt, the processor will return execution to the HALT state. While in AutoHALT Power-Down state, the processor will process bus snoops. 2.1.3 Stop-Grant State When the STPCLK# pin is asserted, the Stop-Grant state of the processor is entered 20 bus clocks after the response phase of the processor issued Stop-Grant Acknowledge special bus cycle.
Low Power Features the assertion of the SLP# signal. The SLP# pin should only be asserted when the processor is in the Stop Grant state. SLP# assertions while the processor is not in the Stop-Grant state is out of specification and may result in unapproved operation. Snoop events that occur while in Sleep State or during a transition into or out of Sleep state will cause unpredictable behavior. In the Sleep state, the processor is incapable of responding to snoop transactions or latching interrupt signals.
Low Power Features • BPRI# control for address and control input buffers • Dynamic on-die termination disabling • Low VCCP (I/O termination voltage) The Intel Celeron M processor incorporates the DPWR# signal that controls the data bus input buffers on the processor. The DPWR# signal disables the buffers when not used and activates them only when data bus activity occurs, resulting in significant power savings with no performance impact.
Electrical Specifications 3 Electrical Specifications 3.1 FSB and GTLREF The Intel Celeron M processor FSB uses Advanced Gunning Transceiver Logic (AGTL+) signalling technology, a variant of GTL+ signalling technology with low power enhancements. This signalling technology provides improved noise margins and reduced ringing through lowvoltage swings and controlled edge rates. The termination voltage level for the Intel Celeron M processor AGTL+ signals is VCCP = 1.05 V (nominal).
Electrical Specifications 3.3.1 VCC Decoupling Regulator solutions need to provide bulk capacitance with a low effective series resistance (ESR) and keep a low interconnect resistance from the regulator to the socket. Bulk decoupling for the large current swings when the part is powering on, or entering/exiting low-power states, must be provided by the voltage regulator solution. For more details on decoupling recommendations, please refer to the platform design guides.

Electrical Specifications 3.6 Signal Terminations and Unused Pins All RSVD (RESERVED) pins must remain unconnected. Connection of these pins to VCC, VSS, or to any other signal (including each other) can result in component malfunction or incompatibility with future Intel Celeron M processors. See Section 4.1 for a pin listing of the processor and the location of all RSVD pins. For reliable operation, always connect unused inputs or bidirectional signals to an appropriate signal level.

4.2 Alphabetical Signals Reference Table 25. Signal Description (Sheet 1 of 7) Name Type Description 32 Input/ Output A[31:3]# (Address) define a 2 -byte physical memory address space. In subphase 1 of the address phase, these pins transmit the address of a transaction. In sub-phase 2, these pins transmit transaction type information. These signals must connect the appropriate pins of both agents on the Intel Celeron M processor FSB.
Table 25. Signal Description (Sheet 2 of 7) Name COMP[3:0] Type Analog Description COMP[3:0] must be terminated on the system board using precision (1% tolerance) resistors. Refer to the platform design guides for more details on implementation. D[63:0]# (Data) are the data signals. These signals provide a 64-bit data path between the FSB agents, and must connect the appropriate pins on both agents. The data driver asserts DRDY# to indicate a valid data transfer.
Table 25. Signal Description (Sheet 3 of 7) Name Type Description DPSLP# Input DPSLP# when asserted on the platform causes the processor to transition from the Sleep State to the Deep Sleep state. In order to return to the Sleep State, DPSLP# must be deasserted. DPSLP# is driven by the ICH4-M component and also connects to the MCH-M component of the Intel 855PM, Intel 855GM, or 852GM chipset.
Table 25. Signal Description (Sheet 4 of 7) Name HIT# HITM# IERR# IGNNE# INIT# ITP_CLK[1:0] LINT[1:0] LOCK# Type Input/ Output Input/ Output Description HIT# (Snoop Hit) and HITM# (Hit Modified) convey transaction snoop operation results. Either FSB agent may assert both HIT# and HITM# together to indicate that it requires a snoop stall, which can be continued by reasserting HIT# and HITM# together. Output IERR# (Internal Error) is asserted by a processor as the result of an internal error.
Table 25. Signal Description (Sheet 5 of 7) Name Description Output Probe Ready signal used by debug tools to determine processor debug readiness. Please refer to the ITP700 Debug Port Design Guide and the platform design guides for more implementation details. Input Probe Request signal used by debug tools to request debug operation of the processor. Please refer to the ITP700 Debug Port Design Guide and the platform design guides for more implementation details.
Table 25. Signal Description (Sheet 6 of 7) Name Type Description Input SLP# (Sleep), when asserted in Stop-Grant state, causes the processor to enter the Sleep state. During Sleep state, the processor stops providing internal clock signals to all units, leaving only the Phase-Locked Loop (PLL) still operating. Processors in this state will not recognize snoops or interrupts.
Table 25. Signal Description (Sheet 7 of 7) Name Description TRDY# Input TRDY# (Target Ready) is asserted by the target to indicate that it is ready to receive a write or implicit writeback data transfer. TRDY# must connect the appropriate pins of both FSB agents. TRST# Input TRST# (Test Reset) resets the Test Access Port (TAP) logic. TRST# must be driven low during power on Reset.
