NXP Semiconductors MSC7116VM1000

Overview

MSC7116VM1000 from Freescale Semiconductor is a StarCore® SC1400-based DSP SoC integrating a 266 MHz DSP core, 192 KB M1 SRAM, 192 KB M2 memory, DDR controller supporting 133 MHz DDR-SDRAM, dual TDM interfaces (up to 128 channels), and IEEE 802.3-compliant 10/100 Mbps Ethernet MAC - deployed in voice-over-IP gateways, media processors, and telecom access equipment.

For engineers reviewing the MSC7116VM1000 datasheet, MSC7116VM1000 pinout, MSC7116VM1000 application, or MSC7116VM1000 equivalent, key selection considerations include DDR timing compliance at 133 MHz, AHB-Lite crossbar arbitration for multi-master concurrency, SC1400 core power management in Stop/Wait modes, and TDM frame sync programmability for E1/T1 interface alignment.

Technical Context

The MSC7116VM1000 implements a StarCore SC1400 extended DSP core with 16-way 16 KB instruction cache, four-entry write buffer, and programmable interrupt controller. Its AHB-Lite crossbar switch supports concurrent transfers across four master ports (core, DMA, HDI16, timers) and six slave ports (M1/M2 RAM, DDR controller, Ethernet, TDMs), with per-port priority and bus parking.

Internal clock synthesis includes a PLL generating 266 MHz for the core and 133 MHz for peripherals, plus independent clock domains for DDR, timers, and TDM modules. The device supports glueless interfacing via 16-bit HDI16 host interface, 32-bit DDR data bus with byte enables, and dual TDMs with hardware A-law/μ-law conversion and up to 50 Mbps per channel.

Key Specifications

Pinout & Package

MSC7116VM1000 uses a 400-ball Molded Array Process Ball Grid Array (MAP-BGA) package measuring 17 mm × 17 mm with 0.8 mm ball pitch. Thermal design requires attention to VDDC/VDDM/VDDIO decoupling and thermal vias under the die area per Freescale's recommended layout guidelines.

FAQ

What is the maximum DDR clock frequency supported by the MSC7116VM1000?

The MSC7116VM1000 DDR controller supports a maximum clock frequency of 133 MHz, enabling data transfer rates up to 266 MT/s on a 32-bit bus. This is specified in the AC timing section of the datasheet (Rev. 13, Table 6) and requires strict adherence to SSTL_2 termination, VREF tracking, and PCB layout rules for signal integrity. The MSC7116VM1000 must be configured with appropriate timing parameters in its DDR initialization sequence to operate reliably at this rate.

Does the MSC7116VM1000 include an integrated Ethernet PHY?

No, the MSC7116VM1000 integrates only a Media Access Control (MAC) layer compliant with IEEE 802.3/802.3u/802.3x/802.3ac standards. It requires an external PHY device connected via MII or RMII interface. The MSC7116VM1000 provides MDC/MDIO management signals and supports auto-negotiation, VLAN tagging, and full/half-duplex operation - but physical layer signaling (e.g., 10BASE-T, 100BASE-TX) is handled externally.

How many TDM channels does the MSC7116VM1000 support, and what framing protocols are natively handled?

The MSC7116VM1000 features two independent TDM modules, each supporting up to 128 time slots per frame, for a total of 256 channels. It natively supports E1 (32-slot), T1 (24-slot), MVIP, SCAS, and H.110 bus framing through programmable frame sync and clock routing. Hardware A-law/μ-law companding is implemented on-chip, eliminating the need for external codec ICs in voice-centric designs using the MSC7116VM1000.

What power supply rails are required for the MSC7116VM1000, and what are their tolerance ranges?

The MSC7116VM1000 requires four distinct supply rails: VDDC (1.14–1.26 V for core/PLL), VDDM (2.38–2.63 V for DDR I/O), VDDIO (3.14–3.47 V for general I/O), and VDDPLL (1.14–1.26 V). Each rail has tight regulation requirements - for example, VREF must track 50% of VDDM ±2% - and sequencing must follow Freescale's voltage ramp order (VDDM first, then VDDC/VDDPLL, then VDDIO) to prevent latch-up. These specifications are defined in Section 2.2 of the MSC7116VM1000 datasheet.

Is the MSC7116VM1000 pin-compatible with other members of the MSC71xx family?

No, the MSC7116VM1000 is not pin-compatible with other MSC71xx variants such as MSC7122 or MSC7144. While sharing the same MAP-BGA–400 package footprint, ball assignments differ significantly - particularly for DDR signals (DQS/DQM), TDM pins, and peripheral interfaces. The MSC7116VM1000 datasheet (Section 1.2) confirms unique signal mapping, and Freescale documentation explicitly states that PCB layout is not interchangeable across the family. Migration requires full schematic and layout revision.
