5.5 V voltage range on VCC. The ADM3066E integrates
a VIO logic supply enabling a flexible digital interface
capable of operating as low as 1.62 V and allowing
direct connection to low power processors and FPGAs
that operate at 1.8 V. The entire ADM306xE transceiver
series offer IEC61000-4-2 ESD protection provided
on the bus pins in addition to receiver short circuit,
open circuit, and floating input failsafe protection. Also
featured is a high data rate – up to 50 Mbps – required
by high speed motor control applications, extended
industrial temperature ranges of -40°C to +125°C and
connectivity for 128 nodes on the bus.

New MCU software eliminates an FPGA to
achieve a sub-1 microsecond current loop in
industrial systems
Texas Instruments (TI) (NASDAQ: TXN) today
introduced DesignDRIVE Fast Current Loop software
that makes C2000™ microcontrollers (MCUs) the first
devices to push current-loop performance to less than
1 microsecond. Together, TI’s C2000™ MCU portfolio
and DesignDRIVE software delivers system-on-chip
(SOC) functionality which simplifies drive control system
development. New DesignDRIVE Fast Current Loop
software out performs traditional microcontroller (MCU)-
based current-loop solutions and can simplify designs
by eliminating the field-programmable gate array
(FPGA) typically used for external current-loop control.
Fast Current Loop software is a free update available for
C2000 controlSUITE™ software. For more information,

TI’s DesignDRIVE technology is a unified hardware and
software platform that makes it easier for engineers
to develop and evaluate solutions for a variety of
industrial drive and servo topologies. As a key part of
DesignDRIVE solutions, the new Fast Current Loop
software enables developers to achieve higher control
performance while saving valuable board space and
simplifying thermal considerations.
Features and benefits of TI’s DesignDRIVE Fast Current
Loop software
Innovative subcycle pulse-width modulation (PWM)
update techniques significantly improve control-
loop bandwidths to potentially triple the motor torque
response.
A novel cycle-scavenging C2000 MCU needs only 460
nanoseconds for field-oriented control processing.
A new complex controller replaces traditional
proportional integration control and facilitates greater
stability at higher speeds.
Industrial drive systems designed with Fast Current Loop
software on a C2000 MCU, like the TMS320F28379,
delivers SOC functionality to reduce board space,
complexity and overall cost.
Get started today
Developers can get started immediately by downloading
TI’s free new Fast Current Loop software on the
DesignDRIVE solutions page. In addition, the C2000
DesignDRIVEdevelopment kit for industrial motor control
(TMDXIDDK379D) includes the hardware for industrial
motor control designs and can support two simultaneous
Fast Current Loop s as well as DesignDRIVE Position
Manager technology. The kit is also available as the
reference design, TIDM-SERVODRIVE.
Pricing and availability
The new DesignDRIVE Fast Current Loop is available
today for the C2000 Delfino™ TMS320F2837x family
of MCUs for advanced control applications start at
US$11.32 in 1,000-unit quantities available in the TI store
and at authorized distributors. Additionally, the C2000
DesignDRIVE development kit (TMDXIDDK379D) is
available for immediate purchase for $999. TI plans to
offer Fast Current Loop support for the TMS320F2807x
