Product details
Overview
MC7447AVS1000NB from Freescale Semiconductor is a 32-bit PowerPC G4 RISC microprocessor with 512-Kbyte unified L2 cache, 1.3 V core supply, and 1000 MHz maximum core frequency. It integrates superscalar execution, AltiVec SIMD unit, dual-precision FPU, and hardware-enforced MESI coherency - deployed in high-performance networking and embedded computing systems requiring deterministic real-time throughput.
For engineers reviewing the MC7447AVS1000NB datasheet, MC7447AVS1000NB pinout, MC7447AVS1000NB application, or MC7447AVS1000NB equivalent, key selection criteria include verified DFS (Dynamic Frequency Switching) support, temperature diode integration, 360-ball ceramic BGA package compatibility, and precise L2 cache latency (9-cycle L1 miss → L2 hit).
Technical Context
The MC7447AVS1000NB implements a seven-stage superscalar pipeline with three issue queues (FIQ, VIQ, GIQ), supporting up to 16 in-flight instructions and three retirements per cycle. Its memory subsystem uses separate 32-Kbyte 8-way set-associative L1 instruction and data caches, plus an on-die 512-Kbyte 8-way unified L2 cache with 256-bit interface and 64-byte two-sectored lines.
It features dual MMUs (128-entry 2-way TLBs), IEEE 754-compliant FPU, AltiVec vector units (VIU1/VIU2/VFPU/VPU), and hardware-managed power states (Nap, Sleep, Deep Sleep). Dynamic Frequency Switching reduces core clock by 50% under software control, while an integrated temperature diode enables closed-loop thermal monitoring.

FAQ
What is the maximum guaranteed operating frequency of the MC7447AVS1000NB?
The MC7447AVS1000NB is rated for a maximum core frequency of 1000 MHz under nominal conditions: 1.3 V ±50 mV core supply, 65°C junction temperature, and compliant MPX bus timing. This rating is validated per Freescale's sorting methodology using SYSCLK-derived PLL multiplication and confirmed in Table 8 of the Hardware Specifications Rev. 5 document.
Does the MC7447AVS1000NB support dynamic voltage scaling in addition to Dynamic Frequency Switching?
The MC7447AVS1000NB supports voltage derating (1.2 V ±50 mV) per Section 5.3 of its specification, but this is a static configuration - not dynamic. Only Dynamic Frequency Switching (DFS) is implemented as a runtime software-controlled feature; voltage must be set at boot and held constant during DFS operation to maintain timing margins and avoid instability.
Is the MC7447AVS1000NB pin-compatible with the MPC7447EC?
Yes, the MC7447AVS1000NB is a footprint-compatible, drop-in replacement for the MPC7447EC in existing designs, as explicitly stated in the Freescale documentation (Feature Note, page 3). Both use the identical 360-ball ceramic BGA (HCTE) package with matching pinout, thermal pad, and power delivery requirements - no PCB changes are needed.
What thermal management features are integrated into the MC7447AVS1000NB?
The MC7447AVS1000NB integrates two hardware thermal management features: a calibrated on-die temperature diode (TDIODE pin) providing analog voltage proportional to junction temperature, and Dynamic Frequency Switching (DFS) that halves core clock under software control to reduce power dissipation. These eliminate dependency on external thermal sensors or complex power management ICs.
Can the MC7447AVS1000NB operate with 2.5 V I/O voltage while maintaining 1.3 V core voltage?
Yes, the MC7447AVS1000NB supports 2.5 V I/O operation when BVSEL is asserted high (or tied to HRESET), provided OVDD is supplied at 2.5 V ±5%. Core voltage (VDD/AVDD) remains independent at 1.3 V ±50 mV. This dual-voltage capability enables interoperability with legacy 2.5 V peripheral buses while preserving low-power core operation.
