TI device nomenclature also includes a suffix with the device family name. This suffix indicates the
package type (for example, PBK) and temperature range (for example, A).
provides a legendfor reading the complete device name for any family member.

Extensive documentation supports all of the TMS320 DSP family generations of devices from product
announcement through applications development. The types of documentation available include: data
sheets and data manuals, with design specifications; and hardware and software applications.
TMS320x280x device reference guides are applicable to the UCD9501 device as well. Useful reference
documentation includes:
SPRU051:
TMS320x281x, 280x Serial Communication Interface (SCI) Reference Guide
Describes the SCI, which 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.
SPRU059:
TMS320x281x, 280x Serial Peripheral Interface (SPI) Reference Guide
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 bit-transfer rate. The SPI is used for communications between the
DSP controller and external peripherals or another controller.
SPRU074:
TMS320x281x, 280x Enhanced Controller Area Network (eCAN) Reference Guide
Describes the eCAN that uses established protocol to communicate serially with other
