NXP Semiconductors MSC8101VT1375F

Overview

MSC8101VT1375F from Freescale Semiconductor is a network-dedicated digital signal processor integrating the SC140 four-ALU DSP core, 512 KB on-chip SRAM, a programmable communications processor module (CPM), dual-phase-lock-loop clocking, and a 64-bit system bus. It delivers 1200 core MMACS at 300 MHz with 1.6 V core voltage and supports TDM, Ethernet, and ATM interfaces in wireless infrastructure baseband processing.

For engineers reviewing the MSC8101VT1375F datasheet, MSC8101VT1375F pinout, MSC8101VT1375F application, or MSC8101VT1375F equivalent, key selection criteria include its 300 MHz SC140 core performance, integrated CPM for multi-protocol networking, 512 KB unified internal memory eliminating external program/data RAM, and FC-PBGA-484 lidded package compatibility with thermal and layout constraints in high-density telecom boards.

Technical Context

The MSC8101VT1375F implements a 32-bit RISC-based CPM engine supporting concurrent ATM (155 Mbps AAL0/1/2/5), 10/100 Mbit Ethernet via MII, and up to four E1/T1 or one E3/T3 interface - all managed independently of the SC140 core. Its System Integration Unit (SIU) enables glueless interfacing to 60x-compatible multi-master buses and provides configurable interrupt routing across eight IRQ lines.

Core timing is governed by two independent PLLs: a system PLL for bus and memory clocks, and SC140-specific DPLLs for SCC/SCM peripherals. The device uses a 0.13 µm copper process, operates at 1.6 V core / 3.3 V I/O, and integrates a 16-channel DMA engine with burst support and sophisticated addressing for offloading data movement from the DSP core.

Key Specifications

Pinout & Package

The MSC8101VT1375F is housed in a 17 mm × 17 mm lidded FC-PBGA package with 484 balls (lead-free or lead-bearing option). Pin assignments follow standard BGA ball-grid nomenclature; signals are functionally grouped into power, clock, reset, system bus, memory controller, CPM I/O ports (A–D), JTAG, and reserved categories as defined in Rev. 19 documentation.

FAQ

What is the core architecture of the MSC8101VT1375F?

The MSC8101VT1375F features the StarCore SC140 four-ALU DSP core optimized for efficient C/C++ compilation, with variable-length execution set (VLES) architecture, JTAG/Enhanced OnCE debug support, and 1200 MMACS performance at 300 MHz. This core forms the computational foundation of the MSC8101VT1375F, enabling deterministic real-time processing in telecom baseband applications.

Does the MSC8101VT1375F support Ethernet connectivity?

Yes, the MSC8101VT1375F integrates a communications processor module (CPM) with native 10/100 Mbit Ethernet support via MII interface, allowing direct connection to PHY devices without external MAC controllers. This capability is confirmed in the MSC8101 Technical Data Rev. 19 feature list and block diagram, making the MSC8101VT1375F suitable for packet telephony gateways and VoIP infrastructure.

What package type does the MSC8101VT1375F use?

The MSC8101VT1375F uses a 17 mm × 17 mm lidded flip-chip plastic ball grid array (FC-PBGA) with 484 solder balls, available in both lead-free and lead-bearing variants. This package is specified in Chapter 3 of the MSC8101 Technical Data Rev. 19 and provides thermal and electrical performance suitable for high-density telecom PCB layouts where the MSC8101VT1375F is deployed.

How much on-chip memory does the MSC8101VT1375F include?

The MSC8101VT1375F includes 512 KB of on-chip SRAM organized as 256K 16-bit words, configured as unified program and data space. This memory eliminates the need for external program or data RAM in many implementations and is directly accessible by both the SC140 core and CPM - a key differentiator of the MSC8101VT1375F in memory-constrained baseband designs.

Can the MSC8101VT1375F replace older Freescale DSPs like the MSC8102?

No - the MSC8101VT1375F is not a drop-in replacement for the MSC8102, which features dual SC140 cores and different memory mapping. While both belong to the StarCore family, the MSC8101VT1375F is a single-core variant with distinct pinout, boot configuration, and CPM register layout. Migration from MSC8102 to MSC8101VT1375F requires hardware redesign and firmware adaptation due to architectural differences in the MSC8101VT1375F implementation.
