DETROIT--At Convergence here, Freescale Semiconductor introduced a new
series of motor control development kits, featuring an integrated
automotive permanent magnet synchronous motor (PMSM) or brushless DC
(BLDC) motor control functionality.
The first development kits in
the series feature Freescale’s Qorivva 32-bit microcontrollers
(MCUs) built on Power Architecture technology and include hardware
and software that help reduce the time needed to develop automotive
motor control applications such as HVAC blowers, electric power
steering, engine cooling fans, fuel, water and oil pumps and wipers.
The initial motor control development kits are powered by
Qorivva 32-bit MCUs, including the MPC560xP, MPC564xL and
MPC560xB families and feature motor control peripherals such as
FlexPWM, CTU, ADC and eTimer modules.
Controller board with the latest
Qorivva 32-bit MCU
Three-phase low-voltage power stage
board with the MC33937A FET pre-driver
Motor control application software
available in source code, based on the Automotive Math and
Motor Control Library Set
controller board and power stage user guides with board
schematics and development kit application notes
visualization/instrumentation tool, excellent for tuning,
debugging and demos
The initial motor control development kits featuring Qorivva
MCUs address the needs of PMSM and BLDC motor control designs.
Freescale plans to extend the series over the course of the next
12 months to include additional Qorivva kits as well as kits
based on the S12 and S12 MagniV 16-bit mixed-signal MCU product
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
