NXP Semiconductors MSC7119VF1200

Overview

MSC7119VF1200 from Freescale Semiconductor is a StarCore® SC1400-based DSP SoC integrating a 300 MHz DSP core, 256 KB M1 SRAM, 192 KB M2 memory, DDR controller supporting 150 MHz DDR-SDRAM, and dual 10/100 Mbps Ethernet MACs - deployed in VoIP gateways, media processors, and TDM-over-IP infrastructure.

For engineers reviewing the MSC7119VF1200 datasheet, MSC7119VF1200 pinout, MSC7119VF1200 application, or MSC7119VF1200 equivalent, key selection criteria include its MAP-BGA–400 package with 17 mm × 17 mm footprint, 300 MHz SC1400 core clock, DDR interface timing compliance at 150 MHz, dual TDM modules supporting up to 128 channels, and IEEE 802.3/802.3u-compliant Ethernet MAC with VLAN tagging and full/half-duplex operation.

Technical Context

The MSC7119VF1200 implements an AHB-Lite crossbar switch with four master and six slave ports, enabling concurrent data transfers between the SC1400 core, DMA, DDR controller, and peripherals - with programmable priority and bus parking per slave port. Its internal PLL generates independent clocks: up to 300 MHz for the core and 150 MHz for the crossbar, DDR, and DMA subsystems.

It features two independent TDM modules supporting E1/T1 frame alignment, hardware A-law/μ-law conversion, and glueless MVIP/SCAS/H.110 interfacing; plus a dedicated Ethernet MAC with integrated FIFOs, DMA access to internal memory, CRC generation/verification, and hash/exact-match address recognition.

Key Specifications

Pinout & Package

MSC7119VF1200 uses a molded array process ball grid array (MAP-BGA–400) package measuring 17 mm × 17 mm with 0.8 mm ball pitch and standard I/O voltage (VDDIO = 3.14–3.47 V). Thermal resistance is RθJA = 39°C/W (natural convection) and RθJC = 7°C/W.

FAQ

What is the maximum operating frequency of the MSC7119VF1200 core?

The MSC7119VF1200 core operates at a maximum frequency of 300 MHz, achieved via its internal PLL generating a dedicated core clock. This frequency is validated under recommended operating conditions (VDDC = 1.14–1.26 V, TJ ≤ 105°C) and enables real-time execution of G.729AB, G.723.1, and wideband codecs. The MSC7119VF1200 datasheet specifies this as the absolute maximum sustained core clock rate without derating.

Does the MSC7119VF1200 support DDR-SDRAM with 150 MHz clocking?

Yes, the MSC7119VF1200 DDR controller supports glueless interface to 150 MHz DDR-SDRAM, as confirmed by AC timing specifications (FCK ≤ 150 MHz) and electrical characteristics (VDDM = 2.38–2.63 V, VREF = 0.49–0.51 × VDDM). It implements SSTL_2 I/O standards, provides DQS-strobed capture, and complies with JEDEC DDR-200 timing requirements - verified in the MSC7119VF1200 datasheet Section 2.5.2.

How many TDM channels does the MSC7119VF1200 support, and what framing protocols are compatible?

The MSC7119VF1200 supports up to 128 TDM channels per module across two independent TDM units, totaling 256 channels. It natively supports E1 (32 timeslots), T1 (24 timeslots), MVIP, SCAS, and H.110 framing with hardware A-law/μ-law conversion. Frame sync and clock signals are programmable per channel, and the MSC7119VF1200 block diagram confirms direct TDM physical layer connectivity without external transceivers.

What boot options are available for the MSC7119VF1200?

The MSC7119VF1200 supports multiple boot modes: internal 8 KB boot ROM execution, external boot via HDI16 (8-bit or 16-bit), I²C EEPROM (up to 1 MB), or SPI Flash. Boot source selection is controlled by strap pins and configuration registers; the MSC7119VF1200 datasheet Section 3.4 details PLL-on/off boot sequences and clock source flexibility (CLKIN = 10–100 MHz).

Is the MSC7119VF1200 pin-compatible with other members of the MSC71xx family?

No, the MSC7119VF1200 is not pin-compatible with other MSC71xx variants such as MSC7122 or MSC7120. While sharing the same MAP-BGA–400 package outline, ball assignments differ significantly - e.g., MSC7119VF1200 dedicates balls to dual Ethernet MAC signals (TX_EN, RX_DV, CRS, COL), whereas MSC7122 routes additional TDM or PCI signals. Pin compatibility must be verified per device-specific ball maps in respective datasheets.
