Microchip Expands Computing Capabilities with Two Embedded Controller Families that Support eSPI Bus Technology
September 27 2017 - 8:03AM
The MEC17XX and MEC14XX families of embedded controllers with
enhanced Serial Peripheral Interface (eSPI), the host interface
supported by the latest PC computing chip sets, are now available
from Microchip Technology Inc. (NASDAQ:MCHP). Both families support
the eSPI bus technology that is required for new, upcoming
computing applications. The MEC17XX family is based on an ARM®
Cortex®-M4F core and has advanced hardware-accelerated cryptography
algorithms to efficiently support the secure boot of a computer.
The family offers several additional features including two UARTS
and an extended industrial operating temperature range that make
the family ideal for industrial computing. In addition, Microchip’s
popular MIPS-based MEC14XX family has been expanded to include
functionality for supporting the new eSPI Slave Attached Flash
(SAF) feature, which allows the Microchip embedded controller to be
directly connected to an SPI Flash memory using an on-board master
controller.
These new embedded controllers are part of an
expanded family of devices that have been an integral part in the
computing industry’s transition from LPC to eSPI. The MEC17XX
adds security through cryptography functionality to advance secure
boot, a security feature developed to ensure a system boots only
from software that is trusted by the manufacturer. Furthermore, the
addition of two UARTS and support for industrial temperature is
necessary for industrial computing applications.
“Microchip was the one of the first companies to
support Intel® Corporation’s enhanced Serial Peripheral Interface
(eSPI) along with SMBus and Low Pin Count (LPC) interfaces,” said
Ian Harris, vice president of Microchip’s Computing Products Group.
“We have worked closely with our industry partners and our
customers to continue to stay on the forefront of defining,
implementing and validating new embedded controllers for computing
applications.”
The latest members of the MEC14XX family add a
new level of design functionality for computing engineers by adding
SAF, which is an optimal solution for USB Type-C™ power delivery.
The latest MEC1428 devices are pin and register compatible with the
MEC140X and MEC141X families, which allows designers to easily add
eSPI and additional features and have more flexibility in their
designs. Both families retain eSPI Master Attached Flash (MAF)
capability. All of Microchip’s computing embedded controllers are
supported by a variety of development and debug tools and
evaluation boards, plus datasheets and other documentation.
The eSPI interface has numerous benefits
including allowing for multiple input/output signals to be
configured to support either 3.3V or 1.8V, which reduces the system
cost by eliminating the need for external voltage translators.
These features allow for seamless migration of intellectual
property (IP) across multiple x86 computing platforms including
those based on Intel’s Atom™ processors, Intel’s iCore™ processors
and Ryzen™ processors from Advanced Micro Devices (AMD).
“The flexibility and rich feature set of our
devices supporting the eSPI Interface and enabling the secure boot
methodology are expected to serve the needs of the market well into
the future,” continued Harris.
