NXP Semiconductors MSC8152TAG1000B

Overview

MSC8152TAG1000B from NXP Semiconductors (formerly Freescale) is a dual-core StarCore SC3850 digital signal processor designed for baseband processing in wireless infrastructure. It integrates two 1 GHz DSP cores, 512 KB configurable L2 cache per core, 1056 KB on-chip M3 memory, dual DDR2/DDR3 controllers (800 MT/s), and MAPLE-B baseband acceleration engine supporting Turbo/Viterbi decoding and FFT/iFFT. It targets LTE-Advanced macro base stations and small-cell radio units.

For engineers reviewing the MSC8152TAG1000B datasheet, MSC8152TAG1000B pinout, MSC8152TAG1000B application, or MSC8152TAG1000B equivalent, key selection criteria include dual-DSP throughput at 1 GHz, integrated MAPLE-B offload capability, FC-PBGA–783 package compatibility, DDR3/DDR2 interface timing compliance, and Serial RapidIO 3.125 Gbaud support for fronthaul interconnect.

Technical Context

The MSC8152TAG1000B implements a chip-level arbitration and switching system (CLASS) enabling non-blocking communication between dual SC3850 cores, MAPLE-B, DDR controllers, and high-speed serial interfaces. Its memory subsystem includes separate 512 KB L2 caches per core, 1056 KB shared M3 SRAM, and boot ROM with Ethernet/RapidIO/SPI boot options.

It features five PLLs - three global and two Serial RapidIO-specific - supporting independent clock domains for DSP cores, DDR, SerDes, and QUICC Engine. The QUICC Engine subsystem provides dual RISC processors with dedicated RAM to offload Gigabit Ethernet scheduling from DSP cores, while four TDM modules support glueless E1/T1 framer interfacing at up to 62.5 Mbps per link.

Key Specifications

Pinout & Package

MSC8152TAG1000B is housed in a 29 mm × 29 mm FC-PBGA–783 package with 783 solder balls arranged in a fine-pitch grid. Power delivery is segmented across multiple rails (VDD, GVDD1, GVDD2, QVDD, MVDD, NVDD, SXCVDD1/2, SXPVDD1/2) to isolate analog SerDes, DDR I/O, DSP cores, and peripheral logic domains.

FAQ

What is the maximum DDR3 data rate supported by the MSC8152TAG1000B?

The MSC8152TAG1000B supports DDR3 interfaces operating at up to 400 MHz clock frequency, delivering an effective data rate of 800 MT/s. This is confirmed in Section 2.6 (AC Timing Characteristics) of the Rev. 6 datasheet, which specifies tAC, tDQSQ, and tDQSCK timing parameters compliant with JEDEC DDR3-1600 standards under recommended operating conditions.

Does the MSC8152TAG1000B include hardware support for Turbo decoding?

Yes, the MSC8152TAG1000B includes dedicated Turbo decoding capability within its MAPLE-B (Multi-Accelerator Platform Engine for Baseband) subsystem. The datasheet explicitly states MAPLE-B supports "Turbo decoding, Viterbi decoding, and FFT/iFFT and DFT/iDFT processing" - all implemented in fixed-function hardware to offload the SC3850 DSP cores.

What package type and dimensions does the MSC8152TAG1000B use?

The MSC8152TAG1000B uses a 29 mm × 29 mm FC-PBGA–783 package, as documented in Section 5 ("Package Information") and Figure 40 of the Rev. 6 datasheet. This flip-chip ball grid array has 783 solder balls and is designed for high-density PCB layouts with thermal vias under the die for junction temperature management.

Can the MSC8152TAG1000B boot from Serial RapidIO?

Yes, the MSC8152TAG1000B supports booting via Serial RapidIO, as stated in the "Boot interface options" bullet on page 2 of the datasheet. This enables remote firmware loading from a host processor or flash controller connected over RapidIO, eliminating need for local SPI or I²C boot devices in distributed baseband architectures.

How many independent TDM interfaces does the MSC8152TAG1000B provide?

The MSC8152TAG1000B provides up to four independent TDM modules, each supporting programmable word size (2/4/8/16-bit), hardware A-law/μ-law conversion, and data rates up to 62.5 Mbps per link. This is specified in the feature list on page 2 and verified in the block diagram (Figure 1) showing "Four TDMs 256-Channels each".
