Product details
Overview
MC7448VU1400NC from Freescale Semiconductor is a 1420 MHz PowerPC G4 RISC microprocessor with integrated 1-Mbyte unified L2 cache, IEEE 754-compliant double-precision FPU, and AltiVec SIMD engine. It implements the PowerPC instruction set v1.0 on 90 nm SOI CMOS technology and targets high-performance networking and computing systems requiring deterministic real-time processing, cryptographic acceleration, and media-intensive workloads.
For engineers reviewing the MC7448VU1400NC datasheet, MC7448VU1400NC pinout, MC7448VU1400NC application, or MC7448VU1400NC equivalent, key selection criteria include its 1420 MHz core frequency at 1.20 V, dynamic frequency switching (DFS) support for power scaling, 360-ball ceramic BGA package, and hardware-enforced MESI cache coherency for multiprocessor designs.
Technical Context
The MC7448VU1400NC features a seven-stage superscalar pipeline with up to three instructions plus one branch dispatched per cycle, 16-entry completion queue, and out-of-order issue for AltiVec instructions. Its memory subsystem includes separate 32-Kbyte eight-way set-associative L1 instruction and data caches with hardware MESI coherency, and an on-die 1-Mbyte eight-way unified L2 cache supporting ECC or parity on data and parity on tags.
It integrates dual MMUs (128-entry two-way TLBs), JTAG/COP debug interface, thermal diode, and three power-saving modes (Nap, Sleep, Deep Sleep). Bus interface supports MPX protocol and subset of 60x protocol with configurable I/O voltage modes (1.5 V/1.8 V/2.5 V) selected via BVSEL[0:1] pins at HRESET negation.

FAQ
What is the maximum junction temperature specification for MC7448VU1400NC?
The MC7448VU1400NC has a maximum die-junction temperature (Tj) of 105°C under recommended operating conditions. This limit applies during full-power operation with natural convection cooling on a four-layer board. Exceeding this temperature may trigger thermal throttling or permanent damage. The integrated thermal diode provides real-time monitoring to enable proactive fan control or frequency scaling in the MC7448VU1400NC.
Does MC7448VU1400NC support pin-compatible replacement with MPC7447A devices?
No, MC7448VU1400NC is not pin-compatible with MPC7447A devices despite identical 360-ball BGA footprints. Differences in BVSEL pin behavior-specifically, the 1.8 V mode configuration being incompatible between MC7448VU1400NC and MPC7447A-require PCB layout revision. The MC7448VU1400NC also introduces new DFS control signals and modified power sequencing requirements not present in MPC7447A.
What L2 cache error detection and correction capabilities does MC7448VU1400NC provide?
The MC7448VU1400NC supports configurable ECC or parity on its 1-Mbyte L2 cache data, with mandatory parity on L2 cache tags. When ECC is enabled, it provides single-bit error correction and double-bit error detection (SEC-DED) for L2 data words. Error injection capability allows validation of recovery firmware. This differs from MPC7447A, which lacks L2 ECC support entirely, making MC7448VU1400NC suitable for telecom infrastructure where data integrity is critical.
How does dynamic frequency switching (DFS) operate in MC7448VU1400NC?
DFS in MC7448VU1400NC is controlled via SPR writes to the HID0 register, enabling software-selectable divide-by-two or divide-by-four core clock scaling. When active, DFS reduces both core voltage and frequency proportionally-e.g., 1420 MHz → 710 MHz or 355 MHz-cutting dynamic power quadratically. The feature operates without reset and maintains cache coherency and register state. It is distinct from Nap/Sleep modes, as MC7448VU1400NC remains fully operational during DFS, only at reduced throughput.
Which I/O voltage modes are supported by MC7448VU1400NC and how are they configured?
The MC7448VU1400NC supports 1.5 V, 1.8 V, and 2.5 V I/O voltage modes, selected by sampling BVSEL0 and BVSEL1 pin states at HRESET negation. Mode mapping is: 00=1.8 V, 01=2.5 V, 10=1.5 V, 11=2.5 V. Notably, the 1.8 V mode configuration is incompatible with MPC7447A, requiring board-level redesign. OVDD must match the selected mode exactly; mismatch causes undefined I/O thresholds and potential signal integrity failure in MC7448VU1400NC.
