Product details
Overview
KMC7448VU1400NC from Freescale Semiconductor is a 1420 MHz PowerPC G4 RISC microprocessor with 32 KB L1 instruction and data caches, 1 MB unified L2 cache with ECC support, and dynamic frequency switching (DFS) capability. It implements the PowerPC v1.0 ISA, features an AltiVec SIMD unit, and targets high-performance networking and computing systems requiring deterministic real-time processing, floating-point computation, and multiprocessing coherency.
For engineers reviewing the KMC7448VU1400NC datasheet, KMC7448VU1400NC pinout, KMC7448VU1400NC application, or KMC7448VU1400NC equivalent, key selection criteria include its 90 nm SOI process, 1.20 V core supply at 1420 MHz, 360-ball ceramic BGA package, DFS-enabled power management, and hardware-enforced MESI cache coherency for symmetric multiprocessing designs.
Technical Context
The KMC7448VU1400NC implements a seven-stage superscalar pipeline with out-of-order issue for AltiVec instructions, three independent issue queues (FIQ, VIQ, GIQ), and eleven execution units including four integer units, five-stage IEEE 754-compliant FPU, and four vector units (VIU1, VIU2, VFPU, VPU). It supports both big- and little-endian operation and includes dedicated hardware for hits-under-misses, store merging, and critical quad-word forwarding for AltiVec loads.
Its memory subsystem integrates dual MMUs with 128-entry two-way set-associative TLBs, 8-entry IBAT/DBAT arrays, and a 1-MB eight-way set-associative L2 cache controller supporting programmable write-back/write-through, parity on tags, and ECC or parity on data. The MPX bus interface enables up to 16 concurrent out-of-order transactions with 256-bit data path width.

Equivalent & Alternatives
The following parts are listed as comparable options for similar RISC microprocessor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC7447AVU1400C | Same 1420 MHz speed grade but 512 KB L2 cache without ECC; lacks DFS and thermal diode | Suitable for cost-sensitive embedded control where ECC and dynamic power scaling are non-critical | Select when L2 capacity and reliability requirements are relaxed and thermal monitoring is handled externally |
| MPC7450VU1400C | Successor family with enhanced AltiVec, larger L2 (2 MB), and higher max frequency (1.7 GHz); same 360-ball BGA footprint | Required for applications needing >1.42 GHz sustained throughput or extended vector instruction set compatibility | Choose for forward-compatible designs where PCB reuse is prioritized and higher performance justifies increased power budget |
Compared with MPC7447AVU1400C and MPC7450VU1400C, the KMC7448VU1400NC uniquely balances L2 capacity (1 MB), ECC protection, DFS power agility, and proven qualification for telecom infrastructure-making it optimal for applications where reliability, thermal adaptability, and deterministic real-time response are jointly required.

FAQ
What is the maximum operating temperature for the KMC7448VU1400NC?
The KMC7448VU1400NC has a specified die-junction temperature range of 0°C to 105°C under recommended operating conditions. Its thermal resistance (RθJA = 26°C/W on single-layer board) means that at 15.5 W thermal power, ambient must be kept below 66°C to maintain safe junction temperature. The integrated temperature diode provides real-time monitoring for closed-loop thermal management.
Does the KMC7448VU1400NC support pin-compatible upgrades from earlier MPC7447A devices?
No-the KMC7448VU1400NC is not pin-compatible with MPC7447A despite sharing the same 360-ball BGA package outline. Differences in BVSEL pin configuration for I/O voltage mode selection (1.8 V mode incompatible) and updated power sequencing requirements necessitate PCB layout revision for migration.
How does the L2 cache ECC implementation work in the KMC7448VU1400NC?
The KMC7448VU1400NC implements 64-bit ECC on L2 data and byte-level parity on L2 tags. Single-bit errors are corrected automatically in hardware; double-bit errors trigger machine-check exceptions. ECC is enabled by default and cannot be disabled-ensuring data integrity for mission-critical applications like telecom switching and medical diagnostics.
Can the KMC7448VU1400NC operate with 1.5 V I/O voltage while running at 1420 MHz core frequency?
Yes-the KMC7448VU1400NC supports 1.5 V, 1.8 V, and 2.5 V I/O voltage modes simultaneously with 1420 MHz core operation. BVSEL[0:1] pins must be configured to 1.5 V mode at HRESET negation, and OVDD[0:7] supplies must be set to 1.5 V ± 5%. This maintains full AC timing compliance and eliminates level-shifter components in legacy 1.5 V system designs.
What debugging interfaces are available on the KMC7448VU1400NC?
The KMC7448VU1400NC provides IEEE 1149.1 JTAG boundary-scan (TCK/TMS/TDI/TDO/TRST) and COP (Controller On Processor) debug interface. COP supports real-time instruction trace, hardware breakpoints, and memory access without halting execution-enabling non-intrusive validation of time-critical code paths in the KMC7448VU1400NC.
