DESCRIPTION
FEATURES AND BENEFITS
The TMC4210 is a 1-axis miniaturized
stepper motor controller with an industry
leading feature set. It controls the motor
via Step/Direction interface. Based on
target positions and velocities - which can
be altered on the fly - it performs all real
time critical tasks autonomously. The
TMC4210 offers high level control functions
for robust and reliable operation. The 4
wire serial peripheral interface allows for
communication with the microcontroller.
1-Axis stepper motor controller
3.3 V or 5 V operation with CMOS / TTL compatible IOs
Serial 4-wire interface for µC with easy-to-use protocol
Step/Direction interface to driver
Clock frequency: up to 32 MHz (can use CPU clock)
Internal position counters 24 bit wide
Microstep frequency up to 1 MHz
Read-out option for all motion parameters
Ramp generator for autonomous positioning / speed control
On-the-fly change of target motion parameters
Low power operation: 1.25 mA at 4 MHz (typ.)
Compact Size: ultra small 16 pin SSOP package
Together with
a
microcontroller the
TMC4210 forms a complete motion control
system. High integration and small form
factor allow for miniaturized designs for
cost-effective and highly competitive
Directly controls TMC260, TMC261, TMC262, TMC2660, TMC389,
TMC2100 and TMC2130
