The new Cortex M4 based microcontroller family from Spansion features dual band Flash for over the air remote re-programming, with a native 72 MHz Flash memory access speed. The 200 MHz frequency capable FM4 MCUs target design of human machine interfaces (HMIs) and machine-to-machine (M2M) communications for applications including factory automation, industrial Internet of Things (IoT), motor control, office automation, building management systems, smart meters, digital cameras and multi-function printers.
FM4 features 5V I/O allowing embedded systems designers to use the 5V logic and power drivers common to industrial embedded applications.
The architecture of these MCU is optimized for efficient data movement with a 16kB flash accelerator, allowing zero wait state execution. Peripheral-to-RAM and RAM-to-peripheral data movement is possible without CPU intervention by either an 8-channel DMA or the unique and powerful descriptor system data transfer controller (DSTC).
The high-density RAM supports the large memory requirements of operating systems and is very useful for buffering audio information or Ethernet traffic.
With the above specific features these MCUs also have more than 12 different communications and memory interfaces. Some of the interfaces include Ethernet, CAN, CAN-FD, Secure Digital Input Output (SDIO), Full-speed Universal Serial Bus (USB), I2S, HDMI-CEC, and a combination of up to 16 channels of UAR, SPI, I2C or LIN communication interfaces. The user determines which function is assigned to each channel.
For motor control, these MCUs pack 3 high-speed analog-to-digital converters and 3 complex timer blocks.
The other features include programmable cyclic redundancy check for memory validation, flash ECC, a clock supervisor and dual watchdog timers.
Spansion S6E2C series MCU samples are shipping now and production volumes are expected in the first quarter of 2015 starting at $10.00 per unit for minimum volumes of 1,500 units.
