Product details
Overview
MC7447AHX1420LB from Freescale Semiconductor is a 1420 MHz PowerPC G4 RISC microprocessor with 32-Kbyte L1 instruction and data caches, 512-Kbyte unified on-die L2 cache, and integrated AltiVec SIMD engine. It operates at 1.3 V core supply and supports MPX/60x bus protocols for high-bandwidth memory subsystems in embedded networking and computing systems.
For engineers reviewing the MC7447AHX1420LB datasheet, MC7447AHX1420LB pinout, MC7447AHX1420LB application, or MC7447AHX1420LB equivalent, key selection criteria include verified DFS (Dynamic Frequency Switching) support, temperature diode integration, 360-ball ceramic BGA package compatibility, and confirmed 1420 MHz guaranteed core frequency under nominal 1.3 V ±50 mV operation.
Technical Context
The MC7447AHX1420LB implements a seven-stage superscalar pipeline with four integer units, five-stage IEEE 754-compliant FPU, and four vector units supporting AltiVec instructions. Its memory subsystem includes dual 128-bit L1/L2 interfaces, hardware-enforced MESI coherency, and separate instruction/data MMUs with 128-entry two-way TLBs.
It features dynamic frequency switching (DFS) to halve core frequency under software control, three low-power states (Nap, Sleep, Deep Sleep), and a calibrated on-die temperature diode. The processor supports both big- and little-endian modes and executes up to three instructions per cycle via precise completion logic and 16-entry completion queue.

FAQ
What is the guaranteed maximum operating frequency of the MC7447AHX1420LB?
The MC7447AHX1420LB is binned and tested to guarantee 1420 MHz operation at 1.3 V ±50 mV core supply and junction temperatures up to 105°C. This rating is validated per Freescale's Revision 5 hardware specifications and reflects worst-case silicon performance under full-power mode conditions.
Does the MC7447AHX1420LB support dynamic frequency switching (DFS)?
Yes, the MC7447AHX1420LB includes hardware-supported DFS that allows software to halve the core frequency from 1420 MHz to 710 MHz without changing voltage or resetting the device. This feature reduces typical full-power mode consumption from 21.0 W to ~10.5 W while maintaining full architectural compatibility.
What package type and ball count does the MC7447AHX1420LB use?
The MC7447AHX1420LB uses a 360-ball ceramic ball grid array (HCTE) package with 1.27 mm pitch, RoHS-compliant and qualified for extended temperature operation. This footprint matches all MPC7447A variants and is documented in Section 8 of the Freescale MPC7447A Hardware Specifications Rev. 5.
How is bus voltage selected on the MC7447AHX1420LB?
Bus voltage selection on the MC7447AHX1420LB is controlled by the BVSEL pin (Ball E1), sampled at HRESET negation: logic 0 configures 1.8 V I/O operation, while logic 1 or HRESET level enables 2.5 V mode. This setting determines OVDD input thresholds and must match the applied OVDD supply voltage per Table 3 in the datasheet.
What thermal management features are integrated into the MC7447AHX1420LB?
The MC7447AHX1420LB integrates a calibrated on-die temperature diode (TDIODE pin) and Dynamic Frequency Switching (DFS). The diode provides analog voltage output proportional to junction temperature, enabling closed-loop thermal control; DFS allows runtime frequency reduction to manage power dissipation without hardware intervention.
