Mobile Intel Celeron Processor Features 2.1 New Features in the Mobile Intel Celeron Processor 2.1.1 On-die GTL+ Termination The termination resistors for the GTL+ system bus are integrated onto the processor die. The RESET# signal does not have on-die termination and requires an external 56.2Ω ±1% terminating resistor. 2.1.

® ® Mobile Intel Celeron Processor (0.18µ) in BGA2 and Micro-PGA2 Packages The SMI# interrupt is recognized in the Auto Halt state. The return from the System Management Interrupt (SMI) handler can be to either the Normal state or the Auto Halt state. See the Intel® Architecture Software Developer’s Manual, Volume III: System Programmer’s Guide for more information. No Halt bus cycle is issued when returning to the Auto Halt state from the System Management Mode (SMM).
® ® Mobile Intel Celeron Processor (0.18µ) in BGA2 and Micro-PGA2 Packages The processor will return to the Stop Grant state after the completion of a BINIT# bus initialization unless STPCLK# has been deasserted. RESET# assertion will cause the processor to immediately initialize itself, but the processor will stay in the Stop Grant state after initialization until STPCLK# is deasserted. A transition to the Sleep state can be made by the assertion of the SLP# signal.
® ® Mobile Intel Celeron Processor (0.18µ) in BGA2 and Micro-PGA2 Packages The processor can be reset by the RESET# signal while in the Sleep state. If RESET# is driven active while the processor is in the Sleep state then SLP# and STPCLK# must immediately be driven inactive to ensure that the processor correctly initializes itself. Input signals (other than RESET#) may not change while the processor is in the Sleep state or transitioning into or out of the Sleep state.

The local APIC timer and performance monitor counter interrupts should be disabled before entering the Deep Sleep state or the resulting behavior will be unpredictable. 2.3 GTL+ Signals The mobile Intel Celeron processor system bus signals use a variation of the low-voltage swing GTL signaling technology.

The Open-drain output signals have open drain drivers and external pull-up resistors are required. One of the two output signals (IERR#) is a catastrophic error indicator and is tri-stated (and pulled-up) when the processor is functioning normally.

Processor Initialization and Configuration 7.1 Description The mobile Intel Celeron processor has some configuration options that are determined by hardware and some that are determined by software. The processor samples its hardware configuration at reset on the active-to-inactive transition of RESET#.

® ® Mobile Intel Celeron Processor (0.18µ) in BGA2 and Micro-PGA2 Packages 8. Processor Interface 8.1 Alphabetical Signal Reference A[35:3]# (I/O - GTL+) The A[35:3]# (Address) signals define a 236-byte physical memory address space. When ADS# is active, these signals transmit the address of a transaction; when ADS# is inactive, these signals transmit transaction information. These signals must be connected to the appropriate pins/balls of both agents on the system bus.
® ® Mobile Intel Celeron Processor (0.18µ) in BGA2 and Micro-PGA2 Packages AP[1:0]# (I/O - GTL+) The AP[1:0]# (Address Parity) signals are driven by the request initiator along with ADS#, A[35:3]#, REQ[4:0]# and RP#. AP1# covers A[35:24]#. AP0# covers A[23:3]#. A correct parity signal is high if an even number of covered signals are low and low if an odd number of covered signals are low. This allows parity to be high when all the covered signals are high.
® ® Mobile Intel Celeron Processor (0.18µ) in BGA2 and Micro-PGA2 Packages BNR# (I/O - GTL+) The BNR# (Block Next Request) signal is used to assert a bus stall by any bus agent that is unable to accept new bus transactions. During a bus stall, the current bus owner cannot issue any new transactions. Since multiple agents may need to request a bus stall simultaneously, BNR# is a wired-OR signal that must be connected to the appropriate pins/balls of both agents on the system bus.

During power-on configuration, DEP[7:0]# signals can be enabled for ECC checking or disabled for no checking. DRDY# (I/O - GTL+) The DRDY# (Data Ready) signal is asserted by the data driver on each data transfer, indicating valid data on the data bus. In a multi-cycle data transfer, DRDY# can be deasserted to insert idle clocks.
® ® Mobile Intel Celeron Processor (0.18µ) in BGA2 and Micro-PGA2 Packages IGNNE# (I - 1.5V Tolerant) The IGNNE# (Ignore Numeric Error) signal is asserted to force the processor to ignore a numeric error and continue to execute non-control floating-point instructions. If IGNNE# is deasserted, the processor freezes on a non-control floating-point instruction if a previous instruction caused an error.

NMI (I - 1.5V Tolerant) The NMI (Non-Maskable Interrupt) indicates that an external interrupt has been generated. NMI becomes the LINT1 signal when the APIC is disabled. Asserting NMI causes an interrupt with an internally supplied vector value of 2. An external interrupt-acknowledge transaction is not generated.
® ® Mobile Intel Celeron Processor (0.18µ) in BGA2 and Micro-PGA2 Packages specifications. Clean implies that the signal will remain low, (capable of sinking leakage current) and without glitches, from the time that the power supplies are turned on, until they come within specification. The signal will then transition monotonically to a high (2.5V) state. Figure 24 illustrates the relationship of PWRGOOD to other system signals.
® ® Mobile Intel Celeron Processor (0.18µ) in BGA2 and Micro-PGA2 Packages Unless its outputs are tri-stated during power-on configuration, after an active-to-inactive transition of RESET#, the processor optionally executes its built-in self-test (BIST) and begins program execution at reset-vector 000FFFF0H or FFFFFFF0H. RESET# must be connected to the appropriate pins/balls on both agents on the system bus.

The processor will not recognize snoop and interrupts in the Sleep state. The processor will only recognize changes in the SLP#, STPCLK# and RESET# signals while in the Sleep state. If SLP# is deasserted, the processor exits Sleep state and returns to the Stop Grant state in which it restarts its internal clock to the bus and APIC processor units. SMI# (I - 1.

® ® Mobile Intel Celeron Processor (0.18µ) in BGA2 and Micro-PGA2 Packages Appendix A: PLL RLC Filter Specification A.1 Introduction All mobile Intel Celeron processors have internal PLL clock generators, which are analog in nature and require quiet power supplies for minimum jitter. Jitter is detrimental to a system; it degrades external I/O timings as well as internal core timings (i.e. maximum frequency).

® ® Mobile Intel Celeron Processor (0.18µ) in BGA2 and Micro-PGA2 Packages The mobile Pentium II processor LC filter cannot be used with the mobile Intel Celeron processor. The larger inductor of the old LC filter imposes a lower current rating. Due to increased current requirements for the mobile Intel Celeron processor in the BGA2 and µPGA2 packages, a lower value inductor is required.
