MCU family expanded by 16 members

The 16 variants of the STM32 F427 and F437 micro-controllers with the ARM Cortex-M4 core by ST Microelectronics (France) extend company’s existing STM32 F4 portfolio. Each MCU offers two CAN ports.

THE CORTEX-M4 PROCESSOR COMPRISES a 32-bit micro-controller, floating-point arithmetic unit and digital signal processor (DSP). It offers the maximal achievable performance of 210 DMIPS (566 CoreMark) at 168 MHz. The MCUs provide two CAN ports, four USARTs, four UARTs, six SPI ports, SDIO, two USB, and three I2C interfaces with digital filters. Dedicated audio PLL and two full-duplex I2S channels are available as well as Ethernet 10/100 MAC (IEEE 1588 v. 2 support). Two 12-bit DACs, three 12-bit ADCs, and up to 17 16-bit/32-bit timers are the further features of the MCUs.
With on-chip Flash memory of 1 MiB or 2 MiB, the chips enable developers of connected embedded electronics (for e.g. utility metering, renewable energy, and healthcare) to create applications and accelerate project completion by programming with high-level languages such as Java, Microsoft.Net or uClinux. Both variants have 256 KiB of SRAM. This allows developers to manage the large quantities of code and data without adding external Flash and SRAM or using ROM-less architecture. 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.
“Sophisticated features and connectivity of our newest STM32 micro-controllers bring exceptional user experiences to everyday electronic products,” said Michel Buffa, General Manager, Micro-controller 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.”
The introduced variants join the existing STM32 F407 and F417 series announced in September 2011. Thus, the STM32 family comprises more than 360 separate part numbers spanning ARM Cortex-M0, M3 and M4 cores, with on-chip Flash from 16 KiB to 2 MiB, up to 256 KiB SRAM, and package options from 36 pins to 176 pins. STM32 F427 and F437 micro-controllers are currently sampling and will enter full production during Q1 2013 in LQFP100, LQFP144, LQFP176 and UFBGA176 packages.
