STMicroelectronics Extends Performance Lead in Semiconductors for Smarter Embedded Electronics
(Thomson Reuters ONE) -
Lead customers in energy, medical technology and wireless markets sample
industry's new highest-performing ARM(®) Cortex(TM)-M microcontrollers
Geneva, November 20, 2012 - Designers of smart, connected embedded electronics
for applications such as utility metering, renewable energy, and healthcare,
have begun adopting new class-leading microcontrollers from STMicroelectronics
(NYSE: STM), a global semiconductor leader serving customers across the spectrum
of electronics applications, to meet demands for extra features, performance and
efficiency in their embedded systems.
The STM32 F427 and F437 microcontrollers extend STM32 F4 existing portfolio and
confirm ST's performance lead among devices using the advanced ARM(®)
Cortex(TM)-M4 core by combining the highest-performing version of this core with
the industry's largest Flash memory storage and extra SRAM for running richer
applications, extra communication ports, enhanced security, and best-in-class
power consumption. These features help speed up software design, enhance
application performance, and maximize battery life.
"Sophisticated features and connectivity of our newest STM32 microcontrollers
bring exceptional user experiences to everyday electronic products," said Michel
Buffa, General Manager, Microcontroller Division, STMicroelectronics. "We are
already working with lead customers to design the extended STM32 F4 variants,
which provide up to 2 Mbytes of Flash memory, into applications such as smart
meters, solar panel controllers, wireless modules, and personal medical
monitors."
With large on-chip Flash memory of 1 MByte or 2 Mbytes, the extended STM32 F4
devices enable developers to create more feature-rich applications and
accelerate project completion by programming with high-level languages such as
Java(TM), Microsoft(®) .Net or uClinux(TM). Using high-level languages also
allows embedded-system developers to take advantage of software advances for
desktop applications. All of the extended 1 MByte and 2 MByte variants have 256
KByte SRAM, allowing designs using current devices with 1 MByte Flash and up to
192 Kbyte SRAM to move easily onto a microcontroller with higher SRAM if
required.
The STM32 F437 series provides enhanced security to protect the product
developer's intellectual property (IP) and end-user data against unauthorized
access or tampering. With additional industry-standard security algorithms now
included in the cryptographic and hash co-processor, these devices support MD5,
SHA-1 and SHA-2 secure hash algorithms, AES GCM (Advanced Encryption Standard
Galois/Counter Mode), and CCM (Combined Cipher Machine).
Further information for technical editors:
The Cortex-M4 processor of the STM32 F427 and F437 comprises a 32-bit
microcontroller, floating-point arithmetic unit and Digital Signal Processor
(DSP). Aided by ST's multi-AHB bus matrix, which enhances CPU and DMA (Direct
Memory Access) controller bandwidth, and Adaptive Real-Time (ART) accelerator,
which allows zero-wait execution from Flash, it achieves performance of 210
DMIPS (566 CoreMark) at 168 MHz. This is the maximum performance a Cortex-M4
core can deliver at this frequency.
Adding versions with 1 MByte or 2 MByte of on-chip Flash, all with 256 Kbyte of
SRAM represents a significant expansion of integrated memory resources compared
to other Cortex-M4 microcontrollers in the market. This allows developers to
manage the large quantities of code and data associated with richer applications
without adding expensive external Flash and SRAM (taking advantage of the
external memory interface of the STM32 F4 series) or using ROM-less
architecture. A ROM-less solution can be even more expensive, and can
significantly increase pc-board complexity and electromagnetic emissions.
For applications requiring enhanced connectivity the STM32 F427 and F437 provide
four USARTs and four UARTs, compared with four USARTs and two UARTs in existing
STM32 F2 and F4 devices. Also integrated on-chip are six SPI ports, increased
from three SPI ports on the F2 and F4 series, and optional digital filtering for
the three I(2)C interfaces to promote robust communications.
A total of 16 new STM32 F427 and F437 variants join the existing STM32 F407 and
F417 series announced in September 2011. Overall, ST's STM32 family now
comprises more than 360 separate part numbers spanning ARM Cortex-M0, M3 and M4
cores, with on-chip Flash from 16 KB to 2 MB, up to 256 KB SRAM, and package
options from 36 pins to 176 pins.
The new STM32 F427 and F437 variants present a straightforward pin-to-pin and
software-compatible upgrade path offering extra resources to enhance
applications based on existing STM32 F2 and STM32 F4 devices. In addition, with
larger on-chip memory and the DSP-enhanced Cortex-M4 core, the latest devices
provide a highly integrated alternative for systems using a microcontroller and
separate DSP, also leveraging the extensive STM32 development ecosystem.
Additional key features of STM32 F427/37:
* 4 KB + 80 Byte backup SRAM
* Communication interfaces: 4x USART, 4x UART, 6x SPI, 3x I(2)C with digital
filters, 2x CAN, SDIO, 2x USB OTG
* Dedicated audio PLL and two full-duplex I(2)S channels
* Ethernet 10/100 MAC with IEEE 1588 v2 support
* 2x 12-bit DAC, 3x 12-bit ADC, up to 17 16/32-bit timers
STM32 F427 and F437 microcontrollers are sampling now to lead customers, and
will enter full production during Q1 2013 in LQFP100, LQFP144, LQFP176 and
UFBGA176 packages. ST has released the following prices for 1 MByte and 2 MByte
variants:
STM32F427VGT6 with 1MB Flash, 256KB SRAM in LQFP100 package at $7.45 for 1,000
units/year resale price.
STM32F437IIH6 2MB Flash, 256KB RAM, Crypto/Hash processor in UFBGA176 package at
$9.50 for 1,000 units/year resale price.
