Shanghai, July 3, 2013 - Fujitsu Semiconductor (Shanghai) Co., Ltd. announced today that the first batch of FM4 series 32-bit RISC microcontrollers Based on the ARM Cortex-M4 processor kernel. Fujitsu Semiconductors have launched a total of 84 MB9B560R / 460R / 360R / 160R Series products, which will be available at the end of July 2013.
Sample Pictures
The FM4 series is based on the existing FM3 series that provides products with higher computing performance and enhanced peripheral performance. The new product launched by the FM4 series inherits the high quality and ease of use of the FM3 series, and the application field is more extensive than FM3. New products are suitable for applications that require advanced high-speed computational performance, such as general inverters, servo motors, programmable logic controllers (PLCs) and other industrial equipment and home appliances using variable frequency.
Fujitsu Semiconductors have launched the FM3 series products since 2010, which is committed to providing easy-to -lect, use and reliable microcontroller product lineup. More than 570 products have been launched in the market, and the customer is tailored to a solution suitable for various applications. The FM4 series products can meet the needs of more efficient and functionality to become the latest representative products in this series.
product Overview
The FM4 Series uses the Cortex-M4 core, the New Standard Digital Signal Processor (DSP), and Floating Point Unit (FPU) feature, can provide the performance of advanced complex computing for new microcontrollers. The FM4 series also redesigned an operational algorithm for internal flash memory to speed up the calculation speed and reduce power consumption. Compared with the existing FM3 series of high-performance group products, the processing efficiency of new products is more than four times, and the unit frequency power consumption is reduced.
In addition, the peripheral peripheral of the FM4 series also has improved and improved. To provide better motor control, FM4 upgrade the timer function and fully improve the A / D converter and other analog circuits. In addition, in communication functions, FM4 improves communication IP for high-speed serial data; and adds a DSTC (Descriptor System Data Transfer Controller) function for reducing CPU load. In terms of external memory connections, the FM4 series products continue to support SRAM, NOR flash and NAND flash memory in addition to supplementing SDRAM (synchronous dynamic RAM) and a newly added SD card.
In addition to the above features, the new lineup also inherits the rich features accumulated by the FM3 series through the market for a long time, such as compatible with 3V and 5V levels, as well as memory that can reduce external EEPROM requirements. In addition to the ease of use of previous generation products, FM4 series products will also support the application of higher performance demand.
Due to the different combinations of flash capacity and the number of pins, the new lineup is divided into four series of 84 products. Looking forward to the future, Fujitsu semiconductor will plan to extend product lineup, add more capacity memory, Ethernet Mac; Ethernet Mac; add I2S and HDMI-CEC, etc.
In addition, Fujitsu semiconductors also plan to introduce FM0 + series microcontrollers for low cost and ultra-low power applications. FM4 series, FM3 series and FM0 + series products have adopted the Cortex-M series core, customers can choose the best product based on applicability, the scope of application is more extensive than before; seamlessly by the compatibility of each kernel Scalability, the customer can therefore realize software reuse and smooth transition in different product development.
Product Features
Be
1. Improved flash performance
The bus used for internal flash is wider, allowing reading access without the CPU waiting state, thus achieving faster processing performance and lower power consumption. The lineup product maintains the same quality standards as the previous product, ensuring 100,000 rewrites or 20 years of data maintenance time.
2. Reduce standby power consumption
The calendar circuit and 32-kHz generator circuit use a separate power source to operate the current required to remain at about 1.5 μA. This reduces the series of devices to static standby power consumption.
3. Accurate, fully functional analog circuit
The analog circuit is redesigned from the underlying direction. Due to the adjustment function, the accuracy of the internal oscillator is maintained at ± 2%; the D / A converter can convert 12-bit resolution; the conversion speed of the A / D converter is twice the previous product.
4. Enhance the timer function
Be
The timer for the 3-phase motor, the so-called multi-function timer, has a series of enhanced timer functions, including support for non-symmetrical pulse width modulation (PWM) waveform output and multiple A / D start-up triggers. At the same time, minimum resolution is increased to 6.25 ns.
For improvements to the A / D converter, these enhanced timer functions can bring more accurate motor control while helping to improve the energy efficiency of mobile equipment (industrial equipment and household appliances, etc.).
5. Enhance communication function
Added a transmission speed that supports up to 20 MHz and accelerates SPI communication. In addition, the variable data length has been extended from the previous 9 bits to 16 bits.
The added DSTC circuit can bypass the CPU for high speed data transmission. This circuit uses a descriptor method that uses memory previous descriptor instructions, which can directly access memory and peripherals to transmit data. By continuous operation, the system can reduce the software size (ROM capacity) and reduce power consumption.
6. Expand external interface
In terms of external memory connection, the FM4 series products continue to support SRAM, NOR flash, and NAND flash memory in addition to supplementing SDRAM. Also supports SDIO interfaces (such as SD cards).
7. Provide equivalent resources as FM3 series
As with the FM3 series, new lineup supports 3V and 5V power. Some FM3 products have a work memory (32 KB) in which it is still embedded in standard equipment. It can back up system parameters or data records, and the demand for external EEPROM can be canceled by using the EEPROM simulation library.
