- Builds on Arm® TrustZone® hardware-based cyber protection for
resource-constrained connected devices
- ST-proprietary ultra-low-power technologies create
class-leading MCU for energy-conscious applications
- Contains support for secure boot, full hardware isolation,
hardware crypto accelerators, strengthens protection, enhances
flexibility
Geneva, October 16, 2018 - STMicroelectronics (NYSE:
STM), a global semiconductor leader serving customers across
the spectrum of electronics applications, is bringing sophisticated
cyber-protection to power-conscious connected devices with the new
STM32L5 microcontroller (MCU) series featuring the Arm® Cortex®-M33
core.
Building on the Cortex-M33, which boosts protection for small
devices by integrating Arm's TrustZone® hardware-based security,
ST's STM32L5-series MCUs add further enhancements including
flexible software isolation, secure boot, key storage, and hardware
cryptographic accelerators. They also provide rich functionality,
high performance, and long run-times powered by coin cells or
energy harvesting. Consuming as little as 33nA in shutdown mode and
achieving 402 ULPMark-CP in the EEMBC[1] ULPBench, the new MCU
series builds on the Company's expertise in low-power techniques
such as adaptive voltage scaling, real-time acceleration, power
gating, and multiple reduced-power operating modes proven in
previous STM32L series.
"The STM32L5 series with TrustZone and additional custom
protection features considerably strengthens and hardens
cyber-protection for small IoT devices," said Ricardo De Sa Earp,
Microcontroller Division General Manager, STMicroelectronics. "Also
featuring our unique energy-saving technologies, rich connectivity,
and smart digital and analog peripherals, these devices will be the
first choice to host cutting-edge connected applications."
With extensive integrated digital and analog peripherals, and
consumer and industrial interfaces such as CAN FD[2], USB
Type-C(TM), and USB Power Delivery, STM32L5 MCUs provide an ideal
platform for products such as industrial sensors or controls,
home-automation devices, smart meters, fitness trackers, smart
watches, medical pumps or meters, and many others.
STM32L5-series microcontrollers are sampling now and scheduled
to begin production in Q2 2019.
ST will unveil the STM32L5 series MCUs in a demonstration,
created in collaboration with security-software specialist Prove
& Run at Arm TechCon, October 16-18, in San Jose,
California.
"IoT devices are increasing in intelligence and functionality,
and security needs to be built in from the ground up," said John
Ronco, vice president and general manager, Embedded &
Automotive Line of Business, Arm. "Arm's Platform Security
Architecture (PSA), a common framework for security implementation,
aims to put security at the heart of IoT. The STM32L5 series makes
it easier for developers to build trusted devices on the PSA
framework with the Cortex-M33 processor, TrustZone technology and
enhanced SoC security features."
Dominique Bolignano, President & Founder of Prove & Run,
provider of the ProvenCore-M secure RTOS, said, "Working with ST to
prepare the demonstration, we clearly see how to leverage STM32L5
hardware features to increase the protection needed for connected
devices to handle the latest cyber threats."
Further technical Information:
The TrustZone IP integrated in STM32L5 series MCUs implements
trusted-computing principles for authenticating devices connected
to a network. First conceived for equipment such as desktops,
mobiles, and communication infrastructure, this hardware-based
approach blocks attempts to corrupt devices or software and creates
a protected execution environment for sensitive code and
cyber-protection such as cryptography and key storage. The new
STM32L5 series MCUs, featuring the Cortex-M33 core with TrustZone,
now make this high-end protection accessible for the
resource-constrained embedded systems that drive the smallest IoT
devices.
STM32L5 series users get extra freedom to include or exclude
each I/O, peripheral, or area of Flash or SRAM from TrustZone
protection, allowing sensitive workloads to be fully isolated for
maximum security. In addition, ST has engineered TrustZone to
ensure support for secure boot, special read-out and write
protection for integrated SRAM and Flash, and cryptographic
acceleration including AES 128/256-bit key hardware acceleration,
private key acceleration (PKA), and AES-128 On-The-Fly Decryption
(OTFDEC) to protect external code or data. Active tamper detection
and support for secure firmware install are also included.
In addition to the flexible power-saving operating modes and
ST's ultra-low-power technologies, the STM32L5 series also features
a highly efficient switched-mode step-down regulator that improves
low-power performance when the VDD voltage is high enough and can
be powered up or down on-the-fly.
Leveraging high core performance, including support for DSP
instructions and floating-point arithmetic, STM32L5 series MCUs
achieve up to 165 DMIPS/427 CoreMark[3](TM) using the ST ART
Accelerator(TM) at 110 MHz. As a novel enhancement in STM32L5 MCUs,
the proven ST ART Accelerator now supports both internal Flash and
external memory with an 8KByte instruction cache for greater
efficiency in case the software runs out of external memory.
512 Kbyte dual-bank Flash allows read-while-write operation to
aid device management and ensures a high level of safety by
supporting Error Correction Code (ECC) with diagnostics. There is
also a 256Kbyte-SRAM and features to support high-speed external
memory including single, dual, quad, or octal SPI and Hyperbus
Flash or SRAM, and an interface for SRAM, PSRAM, NOR, NAND or
FRAM.
The STM32L5 series also introduces new digital peripherals
including USB Full Speed with dedicated supply allowing customers
to keep USB communication even when the system is powered at 1.8V,
and a UCPD controller compliant with USB Type-C Rev. 1.2 and USB
Power Delivery Rev. 3.0 specifications.
Smart analog features include a state-of-the-art
analog-to-digital converter (ADC), two power-gated
digital-to-analog converters (DAC), two ultra-low-power
comparators, and two operational amplifiers with external or
internal follower routing and programmable-gain amplifier (PGA)
capability.
The STM32L5 series is available in standard temperature grade
for consumer and commercial applications, or high-temperature grade
specified from -40°C to 125°C for challenging environments.
