TMS320x281x External Interface (XINTF) Reference Guide (literature number SPRU067) describes the
external interface (XINTF) of the 281x digital signal processors (DSPs).
TMS320x281x Multi-channel Buffered Serial Ports (McBSPs) Reference Guide (literature number
SPRU061) describes the McBSP) available on the 281x devices. The McBSPs allow direct interface between
a DSP and other devices in a system.
TMS320x281x System Control and Interrupts Reference Guide (literature number SPRU078) describes
the various interrupts and system control features of the 281x digital signal processors (DSPs).
TMS320x281x, 280x Enhanced Controller Area Network (eCAN) Reference Guide (literature number
SPRU074) describes the eCAN that uses established protocol to communicate serially with other controllers
in electrically noisy environments. With 32 fully configurable mailboxes and time-stamping feature, the eCAN
module provides a versatile and robust serial communication interface. The eCAN module implemented in
the C28x DSP is compatible with the CAN 2.0B standard (active).
TMS320x281x, 280x Peripheral Reference Guide (literature number SPRU566) describes the peripheral
reference guides of the 28x digital signal processors (DSPs).
TMS320x281x, 280x Serial Communication Interface (SCI) Reference Guide (literature number
SPRU051) describes the SCI that is a two-wire asynchronous serial port, commonly known as a UART. The
SCI modules support digital communications between the CPU and other asynchronous peripherals that use
the standard non-return-to-zero (NRZ) format.
TMS320x281x, 280x Serial Peripheral Interface (SPI) Reference Guide (literature number SPRU059)
describes the SPI a high-speed synchronous serial input/output (I/O) port that allows a serial bit stream of
programmed length (one to sixteen bits) to be shifted into and out of the device at a programmed bittransfer
rate. The SPI is used for communications between the DSP controller and external peripherals or another
controller.
3.3 V DSP for Digital Motor Control Application Report (literature number SPRA550). New generations
of motor control digital signal processors (DSPs) lower their supply voltages from 5 V to 3.3 V to offer higher
performance at lower cost. Replacing traditional 5-V digital control circuitry by 3.3-V designs introduce no
additional system cost and no significant complication in interfacing with TTL and CMOS compatible
components, as well as with mixed voltage ICs such as power transistor gate drivers. Just like 5-V based
designs, good engineering practice should be exercised to minimize noise and EMI effects by proper
component layout and PCB design when 3.3-V DSP, ADC, and digital circuitry are used in a mixed signal
environment, with high and low voltage analog and switching signals, such as a motor control system. In
addition, software techniques such as Random PWM method can be used by special features of the Texas
Instruments (TI) TMS320x24xx DSP controllers to significantly reduce noise effects caused by EMI radiation.
This application report reviews designs of 3.3-V DSP versus 5-V DSP for low HP motor control applications.
The application report first describes a scenario of a 3.3-V-only motor controller indicating that for most
applications, no significant issue of interfacing between 3.3 V and 5 V exists. Cost-effective 3.3-V 5-V
interfacing techniques are then discussed for the situations where such interfacing is needed. On-chip 3.3-V
ADC versus 5-V ADC is also discussed. Sensitivity and noise effects in 3.3-V and 5-V ADC conversions are
addressed. Guidelines for component layout and printed circuit board (PCB) design that can reduce system’s
noise and EMI effects are summarized in the last section.
The TMS320C28x Instruction Set Simulator Technical Overview (literature number SPRU608) describes
the simulator, available within the Code Composer Studio for TMS320C2000 IDE, that simulates the
instruction set of the C28x core.
TMS320C28x DSP/BIOS Application Programming Interface (API) Reference Guide (literature number
SPRU625) describes development using DSP/BIOS.
