Product details
Overview
MC7448VU1000NC from Freescale Semiconductor is a 1000 MHz PowerPC G4 RISC microprocessor with integrated 1-Mbyte unified L2 cache, IEEE 754-compliant double-precision FPU, and AltiVec SIMD engine - designed for high-throughput networking and computing systems requiring deterministic real-time processing, hardware-enforced cache coherency, and dynamic frequency scaling.
For engineers reviewing the MC7448VU1000NC datasheet, MC7448VU1000NC pinout, MC7448VU1000NC application, or MC7448VU1000NC equivalent, key selection criteria include its 90 nm SOI process, 1.15 V core supply, 360-ball ceramic BGA package, DFS support (÷2/÷4), and thermal diode integration - all critical for telecom infrastructure, embedded Linux servers, and signal-processing edge nodes.
Technical Context
The MC7448VU1000NC implements the PowerPC v1.0 ISA on a superscalar, seven-stage pipeline with out-of-order issue for AltiVec instructions and in-order execution for scalar units. It integrates dual MMUs (128-entry 2-way TLBs), Harvard L1 caches (32 KB I/D, 8-way), and an on-die 1-MB unified L2 cache supporting ECC or parity on data and parity on tags.
Its memory subsystem uses the MPX bus protocol with 256-bit interface width, supports big/little-endian operation including misaligned accesses, and delivers 3-cycle integer/vector load latency and 4-cycle FP load latency. Thermal management includes dynamic frequency switching (DFS), Nap/Sleep/Deep Sleep modes, and an on-chip temperature diode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Frequency | 1000 MHz - Sustained clock rate enabling real-time packet classification and encryption at line rate in Layer 3 switches. |
| L2 Cache Size & Type | 1-Mbyte unified, 8-way set-associative - Reduces main memory bandwidth pressure and improves instruction/data locality for streaming workloads. |
| Process Technology | 90 nm CMOS SOI - Enables lower leakage current and higher thermal stability in dense telecom blade environments. |
| Core Supply Voltage | 1.15 V ± 50 mV - Matches low-voltage power delivery architectures common in carrier-grade routers and ATCA platforms. |
| I/O Voltage Support | 1.5 V / 1.8 V / 2.5 V - Allows backward compatibility with legacy DDR1/DDR2 interfaces and forward migration to newer memory subsystems. |
| Thermal Diode | Integrated on-die sensor - Enables closed-loop thermal throttling without external components, critical for fanless industrial compute modules. |
| Dynamic Frequency Switching | ÷2 and ÷4 modes - Permits software-controlled power reduction during low-traffic periods while maintaining system responsiveness. |
Pinout & Package
MC7448VU1000NC is housed in a surface-mount 360-ball ceramic ball grid array (HCTE) package with 1.27 mm pitch, optimized for high-speed signal integrity and thermal dissipation in multi-layer PCBs. The package supports JEDEC-standard reflow profiles and provides dedicated power/ground ball arrays for noise suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| HRESET | Asynchronous reset input | Active-low signal that initializes processor state, clears caches/TLBs, and resets internal clocks - must be held low for ≥100 ns after power stabilization. |
| BVSEL[1:0] | I/O voltage mode select | Two-pin encoding (00=1.8 V, 01=2.5 V, 10=1.5 V) sampled at HRESET negation - determines OVDD threshold and output swing for bus compatibility. |
| TCK/TDI/TDO/TMS/TRST | JTAG boundary-scan interface | IEEE 1149.1-compliant test access port enabling in-system debug, silicon validation, and production test without physical probe contact. |
| CLKIN | Differential clock input | Accepts LVDS or SSTL-2 clock source; feeds PLL generating core and bus clocks - requires matched trace length and 100 Ω differential termination. |
| DBSY/DBSY# | Bus busy status | Open-drain bidirectional signal indicating L2 cache or memory subsystem occupancy - used for arbitration and DMA synchronization in multi-master systems. |
Key Features
| Feature | Design Value |
|---|---|
| AltiVec SIMD Engine | Four vector units (VIU1/VIU2/VFPU/VPU) with 32-entry VR file - accelerates media encoding, cryptography, and radar signal processing without offloading to ASICs. |
| Hardware Cache Coherency | MESI protocol enforcement across L1 D-cache - eliminates software cache-flush overhead in SMP configurations and enables scalable multi-core designs. |
| Out-of-Order AltiVec Issue | Dynamic scheduling of vector instructions independent of scalar flow - improves throughput for mixed workloads like VoIP transcoding with concurrent control-plane tasks. |
| DFS Power States | Nap (JTAG/timebase active), Sleep (PLL only), Deep Sleep (PLL disabled) - reduces idle power by >70% while preserving context for rapid wake-up in bursty traffic scenarios. |
| L2 Cache ECC Support | 64-bit ECC on data, byte parity on tags - corrects single-bit errors and detects double-bit faults in mission-critical control plane firmware storage. |

FAQ
What is the maximum operating junction temperature for MC7448VU1000NC?
The MC7448VU1000NC has a rated maximum die-junction temperature of 105°C under full-power operation. This value is validated per JEDEC JESD51-2/6 standards using natural convection on 1s and 2s2p boards. Thermal design must ensure RθJA ≤ 26°C/W in still air or leverage airflow to maintain Tj within specification during sustained 1000 MHz operation.
Does MC7448VU1000NC support little-endian mode?
Yes, MC7448VU1000NC supports both big-endian and little-endian operation, including misaligned little-endian accesses. Endianness is controlled dynamically via the MSR[LE] bit and can be switched per-instruction stream, enabling interoperability with x86-based peripherals and legacy software binaries in heterogeneous systems.
How does the L2 cache ECC implementation work on MC7448VU1000NC?
The MC7448VU1000NC implements 64-bit ECC on L2 data and byte-level parity on L2 tags. Single-bit errors in data are corrected automatically; double-bit errors trigger machine-check exceptions. ECC is enabled via SPR settings and applies to all cache lines regardless of access type - critical for preventing silent data corruption in control-plane firmware.
Can MC7448VU1000NC operate with 1.8 V I/O while using 1.15 V core voltage?
Yes, MC7448VU1000NC supports independent I/O and core supplies: 1.15 V for VDD/AVDD and 1.8 V for OVDD. BVSEL[1:0] = 00 configures this mode at HRESET negation. The device meets all AC/DC specs under this combination, including VIH/VIL thresholds and output drive strength, as verified in Table 4 and Table 6 of the hardware spec.
Is MC7448VU1000NC pin-compatible with MPC7447A series processors?
MC7448VU1000NC shares the same 360-ball ceramic BGA package and pinout as MPC7447A variants, but differs in BVSEL pin configuration for 1.8 V mode (incompatible with earlier devices) and adds DFS-related control logic. Board-level replacement requires verification of voltage mode selection circuitry and firmware support for DFS registers.
