NXP Semiconductors MSC8157ESAG1000A

Overview

MSC8157ESAG1000A from Freescale Semiconductor is a six-core StarCore SC3850 DSP processor with integrated Security Engine (SEC), MAPLE-B2 baseband accelerator, and QUICC Engine subsystem. It operates at 1 GHz per core, features 3072 KB M3 memory, DDR3 controller supporting 1333 MHz data rate, and 10-lane SerDes supporting Serial RapidIO, PCI Express, CPRI v4.1, and SGMII. It targets wireless infrastructure baseband processing in LTE and 3GPP systems.

For engineers reviewing the MSC8157ESAG1000A datasheet, MSC8157ESAG1000A pinout, MSC8157ESAG1000A application, or MSC8157ESAG1000A equivalent, key selection criteria include multi-core DSP throughput, hardware-accelerated Turbo/Viterbi/FFT, SEC crypto-channel count, CPRI lane count and baud rate support, and FC-PBGA–783 package thermal and routing constraints.

Technical Context

The MSC8157ESAG1000A implements six independent SC3850 DSP cores, each with 32 KB L1 instruction cache, 32 KB L1 data cache, and configurable 512 KB L2 cache. Core arbitration and interconnect are handled by the CLASS fabric, enabling non-blocking access to M2/M3 memory, DDR controller, and accelerators.

Its MAPLE-B2 engine delivers dedicated baseband functions including Turbo encoding/decoding, Viterbi decoding, FFT/iFFT up to 8K points, CRC insertion, and matrix inversion. The Security Engine provides four crypto-channels with eight execution units (AESU, DEU, PKEU, RNG, etc.) for IPSec, SSL/TLS, and LTE protocol acceleration.

Key Specifications

Pinout & Package

MSC8157ESAG1000A is housed in a 29 mm × 29 mm FC-PBGA–783 package with 783 solder balls arranged in a 28 × 28 grid plus corner exclusions. Power delivery is segmented across GVDD (core logic), NVDD (I/O), QVDD (JTAG/PLL), M3VDD (M3 memory), CPRIVDD (CPRI SerDes), and SXCVDD/SXCVSS (SerDes analog supply). Thermal design requires exposed thermal pad on underside per Figure 32 of datasheet.

FAQ

What is the maximum supported DDR3 data rate for the MSC8157ESAG1000A?

The MSC8157ESAG1000A DDR3 controller supports a 667 MHz clock frequency, delivering a 1333 MHz data rate (double data rate). This is validated per JEDEC DDR3-1333 specifications and requires proper termination, fly-by topology, and write-leveling calibration during initialization. The MSC8157ESAG1000A achieves this rate with 64-bit bus width and up to four banks across two controllers.

Does the MSC8157ESAG1000A support CPRI version 4.1 at 6.144 Gbaud?

Yes, the MSC8157ESAG1000A SerDes includes six dedicated CPRI lanes rated for 6.144 Gbaud operation per lane, fully compliant with CPRI specification v4.1. Each lane uses differential signaling with programmable pre-emphasis and receiver equalization, and supports both line and system timing modes as defined in CPRI v4.1 Section 5.2.

How many crypto-channels does the Security Engine in the MSC8157ESAG1000A provide?

The MSC8157ESAG1000A Security Engine contains four independent crypto-channels, each capable of concurrent command descriptor chain execution. These channels drive eight execution units (AESU, DEU, PKEU, RNG, etc.) and support IPSec ESP/AH, IKEv1/v2, SSL/TLS 1.2, and 3GPP/LTE ciphering/integrity algorithms with zero-copy DMA.

What is the function of the CLASS interconnect in the MSC8157ESAG1000A?

The CLASS (Chip-level Arbitration and Switching System) in the MSC8157ESAG1000A is a non-blocking crossbar fabric that arbitrates and routes transactions between six SC3850 DSP cores, MAPLE-B2, SEC, DDR controller, M3 memory, and other initiators. It ensures deterministic latency and full bandwidth utilization for time-critical baseband processing tasks.

Is the MSC8157ESAG1000A pin-compatible with other members of the MSC815xE family?

No, the MSC8157ESAG1000A is not pin-compatible with other MSC815xE variants such as MSC8156E or MSC8158E. While all use FC-PBGA–783 packages, ball assignments for DDR, SerDes, and accelerator interfaces differ significantly. Migration requires PCB redesign; refer to respective datasheet pin tables for exact mapping.
