InstaSPIN™-FOC Software
1 TMS320F2802xF InstaSPIN™-FOC Enabled MCUs
TMS320F2802xF are the second family of devices (26F and 27F — 48-pin package) from Texas
Instruments that include the FAST™ (Figure 1) estimator and additional motor control functions needed for
cascaded speed and torque loops for efficient three-phase field-oriented motor control (FOC).
Together — with F2802xF peripheral drivers in user code — they enable a sensorless (also known as self-
sensing) InstaSPIN-FOC solution which can identify, tune the torque controller and efficiently control your
motor in minutes, without the use of any mechanical rotor sensors. This entire package is called
InstaSPIN-FOC. The FAST estimator is called from execute only ROM while the rest of the functions
required for InstaSPIN-FOC reside in user memory (FLASH and RAM). InstaSPIN-FOC was designed for
flexibility to accommodate a range of system software architectures and customization. The range of this
flexibility is shown in Figure 2.
This document is a supplement to all standard TMS320F2802x documentation, including the standard
device data sheet [TMS320F2802x Piccolo Microcontrollers (literature number SPRS523)], technical
reference manual, and user’s guides. An additional document included with the InstaSPIN-FOC
documentation package is the TMS320F2806xF, TMS320F2802xF InstaSPIN-FOC/TMS320F2806xM
InstaSPIN-MOTION User's Guide (literature number SPRUHJ1), which covers the scope and functionality
of:
• F2802xF devices
• F2802xF ROM contents
• FAST flux estimator
• InstaSPIN-FOC system solutions.
