TMS320DM355 Digital Media System-on-Chip (DMSoC)
SPRUED4— TMS320DM35x DMSoC Serial Peripheral Interface (SPI) Reference Guide This
document describes the serial peripheral interface (SPI) in the TMS320DM35x Digital Media
System-on-Chip (DMSoC). The SPI is a high-speed synchronous serial input/output port that allows
a serial bit stream of programmed length (1 to 16 bits) to be shifted into and out of the device at a
programmed bit-transfer rate. The SPI is normally used for communication between the DMSoC
and external peripherals. Typical applications include an interface to external I/O or peripheral
expansion via devices such as shift registers, display drivers, SPI EPROMs and analog-to-digital
converters.
SPRUED9— TMS320DM35x DMSoC Universal Asynchronous Receiver/Transmitter (UART)
Reference Guide This document describes the universal asynchronous receiver/transmitter
(UART) peripheral in the TMS320DM35x Digital Media System-on-Chip (DMSoC). The UART
peripheral performs serial-to-parallel conversion on data received from a peripheral device, and
parallel-to-serial conversion on data received from the CPU.
SPRUEE0— TMS320DM35x DMSoC Inter-Integrated Circuit (I2C) Peripheral Reference Guide This
document describes the inter-integrated circuit (I2C) peripheral in the TMS320DM35x Digital Media
System-on-Chip (DMSoC). The I2C peripheral provides an interface between the DMSoC and other
devices compliant with the I2C-bus specification and connected by way of an I2C-bus. External
components attached to this 2-wire serial bus can transmit and receive up to 8-bit wide data to and
from the DMSoC through the I2C peripheral. This document assumes the reader is familiar with the
I2C-bus specification.
SPRUEE2— TMS320DM35x DMSoC Multimedia Card (MMC)/Secure Digital (SD) Card Controller
Reference Guide This document describes the multimedia card (MMC)/secure digital (SD) card
controller in the TMS320DM35x Digital Media System-on-Chip (DMSoC). The MMC/SD card is
used in a number of applications to provide removable data storage. The MMC/SD controller
provides an interface to external MMC and SD cards. The communication between the MMC/SD
controller and MMC/SD card(s) is performed by the MMC/SD protocol.
SPRUEE4— TMS320DM35x DMSoC Enhanced Direct Memory Access (EDMA) Controller Reference
Guide This document describes the operation of the enhanced direct memory access (EDMA3)
controller in the TMS320DM35x Digital Media System-on-Chip (DMSoC). The EDMA controller's
primary purpose is to service user-programmed data transfers between two memory-mapped slave
endpoints on the DMSoC.
SPRUEE5— TMS320DM35x DMSoC 64-bit Timer Reference Guide This document describes the
operation of the software-programmable 64-bit timers in the TMS320DM35x Digital Media
System-on-Chip (DMSoC). Timer 0, Timer 1, and Timer 3 are used as general-purpose (GP) timers
and can be programmed in 64-bit mode, dual 32-bit unchained mode, or dual 32-bit chained mode;
Timer 2 is used only as a watchdog timer. The GP timer modes can be used to generate periodic
interrupts or enhanced direct memory access (EDMA) synchronization events and Real Time
Output (RTO) events (Timer 3 only). The watchdog timer mode is used to provide a recovery
mechanism for the device in the event of a fault condition, such as a non-exiting code loop.
SPRUEE6— TMS320DM35x DMSoC General-Purpose Input/Output (GPIO) Reference Guide This
document describes the general-purpose input/output (GPIO) peripheral in the TMS320DM35x
Digital Media System-on-Chip (DMSoC). The GPIO peripheral provides dedicated general-purpose
pins that can be configured as either inputs or outputs. When configured as an input, you can
detect the state of the input by reading the state of an internal register. When configured as an
output, you can write to an internal register to control the state driven on the output pin.
SPRUEE7— TMS320DM35x DMSoC Pulse-Width Modulator (PWM) Reference Guide This document
describes the pulse-width modulator (PWM) peripheral in the TMS320DM35x Digital Media
System-on-Chip (DMSoC).
SPRUEH7— TMS320DM35x DMSoC DDR2/Mobile DDR (DDR2/mDDR) Memory Controller
Reference Guide This document describes the DDR2 / mobile DDR memory controller in the
TMS320DM35x Digital Media System-on-Chip (DMSoC). The DDR2 / mDDR memory controller is
used to interface with JESD79D-2A standard compliant DDR2 SDRAM and mobile DDR devices.
