ST Boosts 32-bit Design Flexibility with Major Extension of STM32 Family

Hi all,

ST has added 28 new devices to the STM32 family, including devices in 36-pin packages at the low end and 144-pin packages at the high end. Compatibility of pin assignments, peripherals and software across all STM32 devices remains a core technical feature throughout this extended family of microcontrollers. The latest MCUs provide 256 Kbytes, 384 Kbytes or 512 Kbytes of embedded Flash for code and data storage, enabling developers to implement new features and enhance the capabilities of existing product platforms. Embedded SRAM has also been increased, to 64 Kbyte for the 72MHz Performance Line variants, and 48 Kbytes for the 36MHz Access Line devices. The Access Line is engineered to encourage entry to 32-bit design for cost-constrained applications, or 16-bit designs.

Extra peripherals embedded in MCUs with 256 Kbytes and larger Flash memories include a Flexible Static-Memory Controller (FSMC) supporting NOR and NAND Flash, SRAM, and CompactFlash memories. The FSMC also supports Intel 8080 and Motorola 6800 modes for parallel interface with LCD controllers. These MCUs also feature a host interface for removable media including SD (Secure Digital), SDIO (Secure Digital Input/Output) and MMC (MultiMediaCard), meeting MultiMediaCard System Specification 4.42 for 8-bit data transfer at 48MHz.

In addition, an I2S port supporting master and slave modes and audio-sampling frequencies from 8kHz to 48kHz has been added, as well as a 2-channel 12-bit DAC and an Embedded Trace Macrocell (ETM) to enhanced debug capabilities. Additional standard peripherals are included with a combination of up to five UARTs/USARTs and three SPI and two I2C bus interfaces. This new combination of peripherals allows the STM32 family to address new markets that require superior connectivity and additional control.

The new STM32 devices are available in LQFP64, LQFP/BGA100 and LQFP144/BGA144 packages. For lower memory-density versions, featuring 32 Kbytes or 64 Kbytes of Flash, a new QFN36, the smallest 6 x 6mm package in the STM32 family, has also been introduced, thereby supporting extended platform scalability for developers seeking a cost-effective common-hardware strategy for multiple market opportunities.

In addition, the new Performance Line MCUs, with 256 Kbytes to 512 Kbytes of Flash, now include an extra PWM timer, offering two timers with seven outputs and dead-time control. These two PWM timers combine up to four standard 16-bit timers to allow support of up to twenty-eight PWM signals using the largest package. With an extra 12-bit ADC, these devices provide up to 21 channels of ADC with triple sample-and-hold capability. This gives the STM32 dual motor-control capabilities, to enable it to drive two 3-phase brushless motors at the same time for air-conditioning units and applications requiring four-wheel drive, for example. All Performance Line MCUs also include a USB port and CAN interface.

In all, the STM32 product range now comprises 46 different Performance Line and Access Line devices. The STM32 environment allows developers to build applications on a standard core, drawing on a large ecosystem of software and tools. Support for developers includes a new ST evaluation board for the latest models introduced, software and firmware libraries, and a wide variety of compatible third-party tools.

Great! Hope they are available soon.

Now we can officially start bugging you about about the next release of enhancements! :D

I assume only a few major customers are your main influence, but a segment LCD controller would be nice. ;)

Congratulations on the new STM32 devices.

I don't know if it is financially viable or technically feasible, but I still think an ultra-ultra-low-powered STM32 chip would be a great addition to your range.

A 36 pin and/or 48 pin device, limited to 8MHz (no PLL) with much reduced sleep and active current would make the STM32 range perfect (in my opinion)

Dear obtronix,

I have already guessed your wish before I post the message :) as you alraedy expressed it in a seperate thread last year. By the way, We will give you and all of this forum members a gift soon on how driving Glass LCD using STM32... ;)

Cheers,

STOne-32

I would like to see ethernet MAC & PHY, and support for capactive touch sensors & scroll wheels all on the chip.

But still it ist not possible to use USB and CAN together with the new devices :(

Ha! You remembered, I will stop complaining. :-]

Hi all,

Just to let you know that ARM & ST are partners for a while and for sure working together on next generations Cores such as Cortex-M3 for Extreme Power Functionality announced April 18, 2008.(

http://www.arm.com/news/20537.html

).

Let's Surf the wave for future together, You are making the right choice

with STM32 Family while releasing your creativity. :)

Cheers,

STOne-32.

I don't think STM can do anything about the core active current, you get what you get when you use an off the shelf model (Cortex M3)
