STMicroelectronics Extends Performance Lead in Semiconductors

STMicroelectronics Extends Performance Lead in Semiconductors for
Smarter Embedded Electronics 
Lead Customers in Energy, Medical Technology and Wireless Markets
Sample Industry's New Highest-Performing ARM(R) Cortex(TM)-M
Microcontrollers 
GENEVA -- (Marketwire) -- 11/20/12 --  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(R) 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(R) .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 require
d. 
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 I2C
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 I2C with
    digital filters, 2x CAN, SDIO, 2x USB OTG
--  Dedicated audio PLL and two full-duplex I2S 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.
