OVERVIEW
The QorIQ LS1020A and LS1022A processors are cost
effective, power-efficient and highly integrated system-onchip designs that extend the reach of the value-performance
product line for enterprise and consumer networking
applications. Incorporating dual ARM® Cortex®-A7 cores
with ECC protection running up to 1.2 GHz, the QorIQ
LS1020A and LS1022A processors are engineered to deliver
outstanding efficiency, delivering over 7,000 CoreMarks®
of performance, as well as virtualization support, advanced
security features and a broad array of high-speed
interconnects and serial connectivity options ever offered
in a sub-3 W processor.
CORE COMPLEX
The QorIQ LS1020A and LS1022A processors both integrate
dual ARM Cortex-A7 cores running up to 1.2 GHz (600 MHz
on the LS1022A) with ECC- protected L1 and L2 caches.
The dual cores each feature 32 KB of L1 instruction and data
cache and share up to 512 KB of coherent L2 cache, as well
as single-bit error detect and correction for both L1 and
L2 caches. Both ARM Cortex-A7 cores in the LS1020A and
LS1022A processors feature the NEON SimD module and
dual-precision floating-point unit (FPU). The DDR memory
controller supports 8-, 16- or 32-bit type 3L and four memory
devices at up to 1,600 MHz (LS1022A limited to DDR3L at up
to 1,033 MHz).

SerDes provides support for high-speed
interfaces, including up to three Gigabit
Ethernet ports with IEEE® 1588 support,
dual DMA- controlled PCI Express®
generation 2.0 ports and a single SATA
3.0 port. The QorIQ LS1020A also
features dual USB controllers—one
supporting SuperSpeed USB 3.0 with
an integrated PHY, the other supporting
USB2.0 functions. Additional interfaces
include QuadSPI, IFC and support
for SD/MMC. For network audio
applications, the LS1020A also includes
support for both ASRC and SPDF. For
power-constrained applications, the
LS1022A provides support for CAN
and UART-based industrial protocols.
Serial IO includes three I2C and two SPI
interfaces on both the LS1020A
and LS1022A.

The QorIQ LS1020A and LS1022A
devices are engineered to deliver
outstanding efficiency, delivering over
7,000 Coremarks, and were designed
specifically to enable a new class of
power-sensitive applications by bringing
together highly efficient ARM® cores and
over twenty years of NXP® networking
expertise and to offer a high level of
integration under 3 W. With ECC
protection on both L1 and L2 caches,
Secure Boot and ARM TrustZone, QUICC
Engine support (on LS1020A), USB 3.0
(on LS1020A), and a broad assortment
of peripheral and I/O features, these
processors devices are purpose-built for
multicore platforms that must perform
more securely, intelligently and efficiently
without sacrificing performance.
