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

•
