NXP Semiconductors MC7448VS1400ND

Overview

MC7448VS1400ND from Freescale Semiconductor is a PowerPC™-compliant RISC microprocessor built on Power Architecture™ technology, operating at 1400 MHz with 1.15 V ± 50 mV core supply voltage, rated for 0–105°C junction temperature, and implemented in RoHS-compliant LGA package. It delivers 2.3 Dhrystone MIPs/MHz performance in Full-Power Mode and supports Dynamic Frequency Switching (DFS) for power-aware system design.

For engineers reviewing the MC7448VS1400ND datasheet, MC7448VS1400ND pinout, MC7448VS1400ND application, or MC7448VS1400ND equivalent, key selection criteria include verified 1400 MHz operation under nominal 1.15 V core bias, thermal power consumption of 13.7 W at 105°C, DFS-enabled frequency scaling down to 250 MHz, and compatibility with MPC7448 hardware specification Rev. 3+ addenda.

Technical Context

The MC7448VS1400ND implements the PowerPC instruction set architecture v1.0 with a superscalar, seven-stage pipeline and integrated L1/L2 cache hierarchy. Its PLL supports VCO frequencies up to 1400 MHz and enables configurable SYSCLK and core clock ratios via PLL_CFG[0:5] register settings.

It features four low-power states-Nap, Sleep, Deep Sleep (PLL disabled), and Doze-with validated thermal power consumption across all modes. Voltage and frequency derating is supported: at 1.0 V ± 50 mV, maximum core frequency is constrained to 1000 MHz with full-power mode thermal dissipation reduced to 9.9 W.

Key Specifications

Pinout & Package

MC7448VS1400ND is housed in a RoHS-compliant Land Grid Array (LGA) package. Pinout information is not provided in the referenced MPC7448ECS01AD Rev. 6 addendum document and is not publicly available in authoritative Freescale/MPC7448 documentation sources.

FAQ

What is the confirmed core supply voltage requirement for MC7448VS1400ND?

The MC7448VS1400ND requires 1.15 V ± 50 mV core supply voltage for guaranteed 1400 MHz operation, as specified in MPC7448ECS01AD Rev. 6 for date code 0613 and later devices. This supersedes earlier 1.1 V specifications used for pre-2007 1400 MHz samples. The MC7448VS1400ND must be powered within this tolerance to meet timing and thermal specifications.

Does MC7448VS1400ND support Dynamic Frequency Switching (DFS)?

Yes, MC7448VS1400ND supports DFS with minimum/maximum core frequencies of 250 MHz/700 MHz in enabled mode, as documented in Table 8 of MPC7448ECS01AD Rev. 6. This feature allows software-controlled frequency scaling to reduce power during low-utilization periods without resetting the MC7448VS1400ND or altering its operational state.

What is the maximum thermal power dissipation of MC7448VS1400ND at 105°C?

At 105°C junction temperature and nominal 1.15 V supply, MC7448VS1400ND exhibits 13.7 W typical full-power mode thermal dissipation, per Table 7 in MPC7448ECS01AD Rev. 6. This value excludes I/O (OVDD) and PLL (AVDD) supply contributions and is measured using the Dhrystone 2.1 benchmark.

Is MC7448VS1400ND pin-compatible with other MPC7448 variants like MC7448VU1400ND?

No, MC7448VS1400ND is not pin-compatible with MC7448VU1400ND. The 'VS' suffix denotes RoHS-compliant LGA packaging, while 'VU' indicates RoHS BGA. These packages have fundamentally different terminal geometries, pitch, and interconnect methods - requiring separate PCB layouts and assembly processes for each variant of MC7448VS1400ND.

What does the 'ND' suffix signify in MC7448VS1400ND?

The 'ND' suffix in MC7448VS1400ND identifies the revision level and application modifier: 'N' specifies 1.15 V ± 50 mV core supply and 0–105°C operating range, while 'D' denotes Revision Level D per Table 17 in MPC7448ECS01AD Rev. 6 - confirming full production qualification and updated PVR register value 0x8004_0202.
