Quieter, Smaller Precision Automation Equipment Possible Using
World-First Single-Chip Motor Controller From STMicroelectronics 
Innovative Stepper Motor Controller Simplifies Design, Beats
Performance of Traditional Multi-Chip Solutions 
GENEVA -- (Marketwire) -- 11/12/12 --  Precision movement and
positioning systems used in industries such as automated
manufacturing and pharmaceutical production can be quieter, smaller,
lighter, simpler and more efficient using the advanced single-chip
digital motion controllers announced today by STMicroelectronics
(NYSE: STM), a global semiconductor leader serving customers across
the spectrum of electronics applications and the world's number one
supplier of standard ICs for industrial applications. 
ST is already working with key customers to design its new cSPIN
controllers into precision equipment such as robotic systems and
industrial automation, stage lighting, security cameras, camera
focusing mechanisms, sewing machines, and general positioning and
rotation equipment. In each case the small size and low weight of the
cSPIN solution enables lower-cost and more responsive equipment
compared to using a conventional multi-chip drive. This helps improve
overall system efficiency by eliminating the need for shunt
resistors, thereby reducing unwanted power dissipation. 
cSPIN also allows precise control over rotation speed, which is
particularly important for repeatable, accurate mixing of liquids in
applications such as handling of medical samples. For all
applications, the smooth and noiseless operation delivers advantages
for users, especially in quiet environments such as laboratories or
on hospital premises. 
As the world's first devices of their type, cSPIN micro-stepping
controllers for 2-phase stepper motors provide several technical
advantages over existing alternatives. Communication with the main
system uses high-level commands via a standard Serial Peripheral
Interface (SPI). The on-chip gate-driver circuitry, for the motor's
power stage, can operate from 8 V to 85 V, which allows applications
to scale smoothly over a wide power range up to 300 W. ST's digital
motion engine is optimized to overcome known challenges such as
avoiding resonance to ensure exceptionally smooth and quiet motor
operation. 
ST's c
SPIN family requires no motor-control software and simplifies
system design by performing all calculation, control and interfacing
functions in a single chip. Competing solutions require software and
multiple discrete chips, which designers must combine before starting
to develop their applications. With cSPIN, projects can begin using
an ST evaluation board containing the control IC, which can be
connected immediately to a stepper motor enabling rapid prototyping. 
Major features of cSPIN controllers: 


 
--  Digital motion engine, gate driver and SPI interface on one chip
--  Programmable speed control and positioning
--  Integrated protection mechanisms: over-temperature, low bus voltage,
    over-current, motor-stall
--  5 Mbit/s SPI interface
--  Fully programmable gate driving
--  Innovative voltage mode control with internal BEMF compensation
    (L6480)
--  Advanced predictive current control with auto-adaptive decay mode
    (L6482)
--  Low standby current

  
The two cSPIN ICs revealed today are the L6480, which supports
micro-stepping operation at up to 1/128 steps resolution, and the
L6482 featuring the predictive control algorithm and the
auto-adaptive decay mode. 
The devices are now ready to enter volume production priced at $3.00
in quantities of 1,000 units.
