Product details
Overview
MSC8122VT8000 from NXP Semiconductors (formerly Freescale) is a quad-core StarCore SC140 DSP processor with 1436 KB on-chip M1 SRAM, 475 KB M2 memory, 4 KB boot ROM, and integrated Ethernet controller supporting 10/100 Mbps MII/RMII/SMII. It operates at up to 800 MHz core frequency (VDD = 1.2 V), features a 128-bit MQBus interconnect, and targets high-channel-density voice/data processing in telecom infrastructure.
For engineers reviewing the MSC8122VT8000 datasheet, MSC8122VT8000 pinout, MSC8122VT8000 application, or MSC8122VT8000 equivalent, key selection criteria include multi-core TDM channel count (up to 4 × 128 Mbps), DSI slave interface bandwidth (32/64-bit synchronous/asynchronous), system bus width (32/64-bit), PLL-configurable clock generation, and FC-PBGA–431 thermal performance (RθJC = 0.9°C/W).
Technical Context
The MSC8122VT8000 implements four independent StarCore SC140 extended DSP cores, each with 224 KB private M1 SRAM, 16-way 16 KB instruction cache, and low-power Wait/Stop modes. Its MQBus operates at core frequency with atomic M2 access arbitration and supports up to 128-bit reads and 64-bit writes between all cores and shared M2 memory.
It integrates a flexible memory controller with three UPMs and SDRAM support, a 16-channel time-multiplexed DMA engine, four programmable TDM modules (2–16-bit word size, A-law/μ-law conversion), and a full-featured Ethernet MAC with VLAN/jumbo frame support, RMON statistics, and local bus master DMA for descriptor handling.

FAQ
What is the maximum operating frequency of the MSC8122VT8000?
The MSC8122VT8000 is rated for operation up to 800 MHz, confirmed by the "VT8000" suffix in its part number per Freescale's MSC8122 ordering information. This frequency is achievable under recommended conditions: VDD = 1.16–1.24 V, VDDH = 3.135–3.465 V, and junction temperature ≤105°C. At 800 MHz, the device delivers approximately 3.2 GOPS (billions of operations per second) across all four SC140 cores.
Does the MSC8122VT8000 support booting from external memory?
Yes, the MSC8122VT8000 supports multiple boot sources including external memory (via system bus or DSI), external host, UART, TDM, and I²C EEPROM. Boot mode is selected by configuration signals (HWBS[7:0]) sampled at reset. The integrated 4 KB boot ROM contains initial firmware that configures PLLs, memory controllers, and peripheral interfaces before loading application code from the selected source.
How many TDM channels does the MSC8122VT8000 support, and what protocols are compatible?
The MSC8122VT8000 integrates four independent TDM modules, each supporting programmable word sizes (2, 4, 8, or 16 bits), hardware A-law/μ-law companding, and data rates up to 128 Mbps aggregate. It provides glueless interface to E1/T1 framers and is compatible with H-MVIP/H.110, TSI switches, and AC-97 codecs-enabling direct connection to telephony line cards without external interface logic.
What is the role of the MQBus in the MSC8122VT8000 architecture?
The MQBus in the MSC8122VT8000 is a 128-bit, core-frequency interconnect that links all four SC140 DSP cores to the shared 475 KB M2 memory. It implements atomic operation control, central round-robin arbitration, and supports up to 128-bit reads and 64-bit writes-ensuring deterministic latency and cache-coherent data sharing critical for real-time multi-core signal processing tasks executed by the MSC8122VT8000.
Is the MSC8122VT8000 pin-compatible with other members of the MSC81xx family?
No, the MSC8122VT8000 is not pin-compatible with other MSC81xx devices such as MSC8156 or MSC8144. While sharing architectural similarities, the FC-PBGA–431 package and signal allocation-including HD[63:0], HA[31:0], DSI, and TDM pin assignments-are specific to the MSC8122VT8000 and documented in its Rev. 16 datasheet. PCB layout must be designed explicitly for this part.
