NXP Semiconductors Microprocessors B4860NSN7QUMD

The QorIQ Qonverge B4860 is a multi-standard wireless base station system-on-chip (SoC) designed for high-performance processing in macrocell base stations. It utilizes 28 nm process technology and features a combination of four dual-threaded e6500 64-bit Power Architecture cores operating at up to 1.8 GHz and six StarCore SC3900FP DSP cores running at up to 1.2 GHz. This architecture supports simultaneous processing of LTE (FDD and TDD), LTE-Advanced, and WCDMA standards, making it suitable for evolving broadband wireless infrastructure. The B4860 integrates advanced hardware accelerators, including the MAPLE baseband accelerator platform, which enhances efficiency in layer 1 processing tasks such as FEC decoding, FFT, and MiMO equalization. It also employs the Freescale Data Path Acceleration Architecture (DPAA) to optimize packet processing, allowing for high data rates and reduced CPU workload on repetitive tasks. With a robust set of features, including 2048 KB of L2 cache, support for DDR3 memory, and multiple high-speed interfaces, the B4860 is engineered to meet the demands of modern wireless operators. Its design emphasizes power efficiency and performance, making it a compelling choice for engineers looking to implement cutting-edge wireless communication solutions.
