TMS320C240x Series of DSP Controllers
1-3 Introduction
1.2 TMS320C240x Series of DSP Controllers
Designers have recognized the opportunity to redesign existing digital motor
control (DMC) systems to use advanced algorithms that yield better perfor-
mance and reduce system component count. DSPs enable:
- Design of robust controllers for a new generation of inexpensive motors,
such as AC induction, DC permanent magnet, and switched-reluctance
motors
- Full variable-speed control of brushless motor types that have lower
manufacturing cost and higher reliability
- Energy savings through variable-speed control, saving up to 25% of the
energy used by fixed-speed controllers
- Increased fuel economy, improved performance, and elimination of
hydraulic fluid in automotive electronic power steering (EPS) systems
- Reduced manufacturing and maintenance costs by eliminating hydraulic
fluid in automotive electronic braking systems
- More efficient and quieter operation due to diminished torque ripple, re-
sulting in less loss of power, lower vibration, and longer life
- Elimination or reduction of memory lookup tables through real-time poly-
nomial calculation, thereby reducing system cost
- Use of advanced algorithms that can reduce the number of sensors
required in a system
- Control of power switching inverters, along with control algorithm
processing
- Single-processor control of multimotor systems
The ’240x DSP controllers are designed to meet the needs of control-based
applications. By integrating the high performance of a DSP core and the
on-chip peripherals of a microcontroller into a single-chip solution, the ’240x
series yields a device that is an affordable alternative to traditional microcon-
troller units (MCUs) and expensive multichip designs. At 30 million instructions
per second (MIPS), the ’240x DSP controllers offer significant performance
over traditional 16-bit microcontrollers and microprocessors.
The 16-bit, fixed-point DSP core of the ’240x devices provides analog design-
ers a digital solution that does not sacrifice the precision and performance of
their systems. In fact, system performance can be enhanced through the use
