1 F2805xMInstaSPIN-MOTION Enabled MCUs

InstaSPIN-MOTION is no longer recommended for new designs and will not have application support. For motion control solutions please see the latest examples released in MotorControl software development kit (SDK) for C2000™ MCUs.

InstaSPIN-MOTION [TMS320F2805xM (54M and 52M — 80-pin package)] is the first offering from Texas Instruments to combine TI 32-bit C2000™ microcontrollers with comprehensive motor-, motion-, speed-, and position-control software. InstaSPIN-MOTION delivers robust velocity and position control at the highest efficiency for motor applications that operate in various motion state transitions. InstaSPIN-MOTION is your own motion control expert, on a single chip.

InstaSPIN-MOTION is a sensorless or sensored field-oriented motor control (FOC) solution that can identify, tune, and control your motor in minutes. InstaSPIN-MOTION features the FAST™ premium software sensor and the SpinTAC™ Motion Control Suite (Figure 2-1). The core algorithms are embedded in the read-only-memory (ROM) on TI 32-bit C2000 microcontrollers (MCUs).

InstaSPIN-MOTION is ideal for applications that require accurate speed and position control, minimal disturbance, or undergo multiple state transitions or experience dynamic speed or load changes.

Table 2-1 provides examples of applications that will most benefit from InstaSPIN-MOTION.
