NXP Semiconductors MSC7116VF1000

Overview

MSC7116VF1000 from Freescale Semiconductor is a StarCore® SC1400-based DSP SoC featuring a 266 MHz core, 384 KB on-chip SRAM (192 KB M1 + 192 KB M2), integrated DDR memory controller supporting 133 MHz operation, and dual 10/100 Mbps Ethernet MACs. It targets voice-over-IP gateways, media gateways, and TDM-to-packet conversion systems requiring real-time signal processing and deterministic packet handling.

For engineers reviewing the MSC7116VF1000 datasheet, MSC7116VF1000 pinout, MSC7116VF1000 application, or MSC7116VF1000 equivalent, key selection criteria include its MAP-BGA–400 package with 17 mm × 17 mm footprint, AHB-Lite crossbar architecture enabling concurrent peripheral access, fieldBIST™ structural integrity testing, and boot flexibility via HDI16, I²C, or SPI interfaces.

Technical Context

The MSC7116VF1000 integrates a single SC1400 DSP core with 16-way 16 KB instruction cache and four-entry write buffer, coupled to an AHB-Lite crossbar switch managing parallel data transfers across four master and six slave ports. Its clock synthesis module independently generates 266 MHz for the core and 133 MHz for peripherals including the DDR controller and DMA channels.

It implements two independent TDM modules supporting up to 128 channels at 50 Mbps each, glueless E1/T1 frame interfacing, and hardware A-law/μ-law conversion. The dual Ethernet MACs comply with IEEE 802.3/802.3u/802.3x/802.3ac, feature VLAN tagging, CRC generation/verification, and direct internal memory access via dedicated DMA controllers.

FAQ

What is the maximum operating frequency of the MSC7116VF1000 core?

The MSC7116VF1000 core operates at a maximum frequency of 266 MHz, as specified in the Freescale MSC7116 datasheet Rev. 13. This frequency is generated by the internal PLL and applies to the StarCore SC1400 DSP extended core. The MSC7116VF1000 achieves this speed under recommended operating conditions including VDDC = 1.14–1.26 V and ambient temperature ≤105°C.

Does the MSC7116VF1000 support booting from external serial flash memory?

Yes, the MSC7116VF1000 supports booting from external serial SPI Flash or EEPROM devices using the built-in boot ROM. Boot configuration is selectable via HDI16, I²C, or SPI interfaces, with flexible clocking options including PLL-on or PLL-off modes and input frequencies ranging from 10–100 MHz. This capability is documented in Section 3.4 "Reset and Boot" of the MSC7116VF1000 datasheet.

How many Ethernet MAC interfaces does the MSC7116VF1000 integrate?

The MSC7116VF1000 integrates two independent 10/100 Mbps Ethernet MAC controllers compliant with IEEE Std. 802.3™, 802.3u™, 802.3x™, and 802.3ac™. Each MAC features internal receive/transmit FIFOs, VLAN tag support, CRC generation/verification, and direct DMA access to internal memories. These interfaces operate via MII or RMII physical layer connections as confirmed in the MSC7116VF1000 block diagram and electrical specifications.

What type of package does the MSC7116VF1000 use, and what are its thermal characteristics?

The MSC7116VF1000 uses a MAP-BGA–400 package measuring 17 mm × 17 mm. Its thermal characteristics include a junction-to-ambient thermal resistance (RθJA) of 39°C/W under natural convection and 31°C/W with 200 ft/min airflow, and a junction-to-case resistance (RθJC) of 7°C/W. These values are validated for the MAP-BGA package per JEDEC standards and appear in Table 4 of the MSC7116VF1000 datasheet Rev. 13.

Can the MSC7116VF1000 interface directly with DDR SDRAM without external logic?

Yes, the MSC7116VF1000 includes an integrated DDR memory controller supporting glueless interface to 133 MHz DDR-RAM with byte enables, 14-bit external address bus (up to 1 GB), and 16-bit or 32-bit data bus. It meets JEDEC DDR specifications and requires only proper termination (VREF = 50% VDDM, VTT tracking VREF) as defined in Section 2.4 of the MSC7116VF1000 datasheet.
