NXP Semiconductors MSC8103M1100F

Overview

MSC8103M1100F from Freescale Semiconductor is a 300 MHz StarCore SC140-based networking digital signal processor with 512 KB on-chip SRAM, integrated communications processor module (CPM), 16-channel DMA, and dual 64-bit buses. It delivers 1200 MMACS and supports TDM, Ethernet, and ATM interfaces in wireless infrastructure and packet telephony systems.

For engineers reviewing the MSC8103M1100F datasheet, MSC8103M1100F pinout, MSC8103M1100F application, or MSC8103M1100F equivalent, key selection factors include its 300 MHz SC140 core performance, CPM-based protocol offload capability, 1.6 V core / 3.3 V I/O power separation, 17 mm × 17 mm FC-PBGA package, and support for E1/T1, HDLC, and Fast Ethernet physical layer interfacing.

Technical Context

The MSC8103M1100F integrates a four-ALU SC140 DSP core executing up to four MAC operations per cycle and a 32-bit RISC-based CPM handling ATM AAL0/1/2/5, 10/100 Mbit Ethernet, and up to four E1/T1 links. Its unified 512 KB SRAM eliminates external memory dependency for many real-time signal processing tasks.

It features a 60x-compatible 64-bit system bus with multi-master support, programmable memory controller supporting SDRAM/Flash/SRAM, and dual PLLs-system PLL and CPM DPLLs-for independent clock domain management across core, CPM, and peripherals.

Key Specifications

Pinout & Package

MSC8103M1100F is housed in a 17 mm × 17 mm lidded flip-chip plastic ball grid array (FC-PBGA) package with lead-bearing or lead-free solder spheres. Pinout information is not publicly documented in available Freescale resources for this specific speed-grade variant (M1100F); official pin assignment requires consultation of the MSC8103 Hardware Design Manual (MSC8103HDG) and associated ball map files.

FAQ

What is the core architecture of the MSC8103M1100F?

The MSC8103M1100F uses the StarCore SC140 four-ALU DSP core operating at 300 MHz. It features variable-length execution set (VLES) architecture optimized for C/C++ compilation, two 32-bit address generation units (AGUs), and executes up to four 16-bit multiply-accumulate operations per clock cycle. This architecture delivers 1200 MMACS and 3000 RISC MIPS, making the MSC8103M1100F suitable for demanding real-time baseband processing in wireless infrastructure.

Does the MSC8103M1100F support Ethernet connectivity?

Yes, the MSC8103M1100F integrates a communications processor module (CPM) that provides native 10/100 Mbit Ethernet MAC functionality. It supports IEEE 802.3-compliant frame handling, full-duplex operation, and can be configured for MII or RMII interfaces. The CPM handles Ethernet framing, CRC generation/checking, and flow control independently of the SC140 core, allowing the MSC8103M1100F to serve as both data plane processor and network interface in VoIP and packet telephony systems.

What memory interfaces does the MSC8103M1100F support?

The MSC8103M1100F includes a programmable memory controller supporting up to eight banks of external memory, including SDRAM, SRAM, Flash, and EPROM. It features a dedicated pipelined SDRAM interface and user-programmable machine (UPM) timing for glueless connection. Internally, it contains 512 KB of unified SRAM accessible as both program and data space, configurable by software to optimize memory layout for specific DSP algorithms used in the MSC8103M1100F implementation.

Is the MSC8103M1100F pin-compatible with other MSC810x devices?

No, the MSC8103M1100F is not pin-compatible with other members of the MSC810x family such as the MSC8122 or MSC8101. While sharing the same FC-PBGA package footprint (17 mm × 17 mm), ball assignments differ significantly due to variations in peripheral sets, bus widths, and CPM configurations. Migration between variants requires PCB redesign and validation of signal integrity, power delivery, and thermal management for the MSC8103M1100F's specific I/O mapping and timing requirements.

What power supply voltages does the MSC8103M1100F require?

The MSC8103M1100F requires two independent supply rails: 1.6 V ± 3% for the core logic and 3.3 V ± 5% for all I/O buffers. This separation enables low-power operation of the SC140 core while maintaining compatibility with standard 3.3 V peripheral interfaces. Total typical power consumption is approximately 2.8 W at full 300 MHz operation, with core-only dissipation below 0.25 W - a critical specification for thermally constrained MSC8103M1100F deployments in dense line cards.
