Family of Integrated Controllers
PRODUCT OVERVIEW
The Marvell
®
ARMADA™ 370 is a highly integrated and high-performance ARM V7-based system-on-chip (SoC) suited
for a variety of home and enterprise applications. With its on-chip floating point engine, 256K L2 cache, and multiple
I/O peripherals, the ARMADA 370 provides new levels of performance, integration, and efficiency, while enabling a
simple system design. The ARMADA 370 is suited for a wide range of applications, including SmartHub for Home,
networked attached storage (NAS) devices, media servers, and wireless access points, as well as networking and
education applications.
The SoCs integrate:
•
High-performance, dual-issue, and out-of-order ARMv7 CPU with Floating Point Unit (FPU) operating up
to 1.2 GHz (3000 DMIPS)
•
Single/double precision FPU (VFP3-16) IEEE 754 compliant
•
32KB-instruction 4-way and 32KB-data 8-way, set-associative L1 cache
•
256KB unified 4-way, set-associative L2 cache/SRAM
•
16-bit DDR3/L-1333 memory interface
•
Two Ethernet networking MACs controllers
•
Four SERDES lanes with versatile muxing options for SGMII, PCIe2.0, and SATA2.0
•
Two x1 PCI Express 2.0 interfaces
•
Two SATA Gen2.0 ports
•
Two USB 2.0 host/device ports with integrated PHY
•
Network security engine with various encryption algorithm support
•
Two TDM channels
•
SDIO/MMC, NAND flash, two SPI, two TWSI, Device Bus, I2S/SPDIF and two UART interfaces
•
Two DMA/XOR engines with two independent channels per each engine
•
RTC and thermal sensor
•
286-pin HSBGA 19 x 19 mm, 1 mm ball pitch, green-compliant package
The innovative Coherency Fabric architecture provides a coherent interconnect between the CPU and the I/Os. The bus
efficiency also enables a high-frequency, high-bandwidth, and low-latency access time throughout the CPU memory
subsystem.
The on-chip Mbus architecture, a Marvell proprietary crossbar interconnect for non-blocking any-to-any connectivity,
enables concurrent transactions among multiple units. This design results in high system throughput, enabling system
designers to create high-performance products.
