Lexington, Mass. Built around an 8-bit core and designed for driving Brushless Direct Current motors, STMicroelectronics' ST7FMC microcontroller family has been Automotive-Grade qualified to meet the specific and rigorous demands of the automotive market.
All the application-specific
devices in the family now operate over the full automotive temperature range
of -40 degrees C to +125 degrees C and include safety features such as
current sensing used for stall detection, asynchronous emergency stop,
write-once registers and Clock Security System (CSS). ST's patented
algorithms also enable the motor-control cell to offer fail-free
The family features an embedded motor-control cell, which includes six-phase
Pulse-Width Modulation control, voltage or current sensing and a
flexible Back Electromotive Force (BEMF) detector for the sensorless
control of permanent-magnet BLDC motors.
The higher integration of the family allows reduced code size, while the
addition of the motor-control cell minimizes the CPU load to control the
motor. In addition an integrated Local Interconnect Network (LIN)
communication interface and the availability of a complete set of standard
peripherals control various application environments.
Dedicated Automotive evaluation and
development kits are designed to allow customers to prove device performance
in their own applications. Furthermore, the ST7FMC family, with easy-to-use
software and complete motor control C-libraries, delivers advantages in
terms of productivity and faster time-to-market.
Housed in tiny TQFP32 and TQFP44 packages, the devices are available now in production volume. Pricing starts from $1.65, depending on the device, in
10,000 unit quantities.
