Preface SPRUIC7 – December 2016 About This Manual This document is for the DM388 processor module. Related Documentation Information regarding the DM388 processor can be found at http://www.ti.com. Board History PCB Revision History PRDN_REV A Production Acronyms The following is a list of acronyms used in this document.
SD, HD, and 4K × 2K resolutions. The DM388 camera starter kit is a development platform with the DM388 processor module connected to a CSK carrier card over board-to-board connectors. Features of the DM388 module and CSK carrier card are detailed in the subsections that follow.
Connecting TMDSCSK388 Module to CSK Carrier Card www.ti.com 2. Place the DM388 module over the board-to-board connectors of the CSK carrier card, then gently press the devices together (see Figure 1-2 Figure 1-3). Figure 1-2. DM388 Module Above CSK Carrier Card Figure 1-3.
32KB of embedded trace buffer (ETB) and 5-pin trace interface for debug • 1.8- and 3.3-V dual voltage buffers for general I/O The DM388 processor module is a low cost, small form factor, higher performance, easy-to-use system- on-module. The development platform has the interfaces that can help build application devices: •...

The following is a list of key features of the DM388 processor module. • TI’s DM388 high performance DaVinci digital media signal processor based on ARM v7 architecture • WiLink 8 Wi-Fi module with 2.4-GHz, single-ended PCB antenna •...
Power Supply The DM388 processor is powered by the CSK carrier through the board-to-board connectors. The CSK carrier card is powered by a +5-V, 3-A, DC power adapter plugged in to the DC power jack (J1). On the CSK carrier card, +5-V is converted into the required supply voltages by using regulators.
Clock Distribution www.ti.com Clock Distribution The DM388 module contains the following reference clocks: • Y1 – 32.768-kHz real-time clock (RTC) to the power management IC (TPS6591133) • Y2 – 20-MHz crystal for the device oscillator inputs • Y3 – 27-MHz crystal for the auxiliary oscillator inputs •...
Power good from PMIC TPS6591133 (nRESPWRO2), power good from DDR power IC (DDR_PGOOD), and reset from the CSK carrier card are monitored to generate the power-on reset (PORn) to the DM388 processor. A 3-input AND gate is used to implement the reset logic. Warm reset for the processor is the input from the CSK carrier card through the board-to-board connector.
DDR3 Interface The DM388 processor supports 32-bit data DDR2, DDR3, DDR3L, and SDRAM interfaces. The two 4-Gb (256M x16) DDR3L chips (MT41K256M16TW-107 [backward compatible to DDR3]) from Micron are used to obtain a memory size of 1 GB. The DDR3L chips are routed using Fly-by topology, shown in Figure 3-3.
NAND Flash Interface The DM388 processor supports a 2-Gb NANDFLASH MT29F2G16ABA from Micron, with a 16-bit data width interfaced to the general purpose memory controller (GPMC) interface of the processor. The NAND flash is interfaced to GPMC chip select #0.
CAM signals are connected to board-to-board connectors. Four voltage level translators (TXS0108ERHYR [U3] for MMC, SN74AVC4T245[U2, U5, U12] for McASP, UART, EN, CLK, and IRQ) convert I/O voltages of the DM388 (3.3 V) to I/O voltages of the Wi-Fi module (1.8 V). Figure 3-5 shows the Wi-Fi and BT interface.
A board-to-board termination connector is provided in the DM388 SOM module, and supports video IN, PCIe, MMC, McASP, and HDDAC. By default, the board-to-board connector is not assembled on the DM388 SOM module. The connector can be populated and used with a third-party carrier card.
Boot Mode Configuration www.ti.com Boot Mode Configuration The DM388 module supports MMC and NAND boot mode configurations. By Default, switch SW1 is configured for NAND flash boot mode. However, other boot modes must be selected by the resistor mount and demount option.
Table 3-3. SW1 Switch Selection Selection MMC boot NAND C Interface The DM388 processor module supports an I C interface that is connected to PMIC and the board-to-board connector. Refer to Section 3.10 for I C addresses of individual devices.
Figure 4-2 show the top and bottom view of the TMDSCSK388 assembly layout. The DM388 board is 2.856 × 2.755 inches (72.55 mm × 70 mm), has eight layers, and is powered through the board-to-board connector. Figure 4-1. TMDSCSK388 Assembly Layout (Top View) Figure 4-2.
