The following table has a Pin Name column that lists all device terminal names and a Signal Name column that lists all internal signal names multiplexed to each terminal which provides a cross reference of internal signal names to terminal names. This table also identifies other important terminal characteristics. 1. BALL NUMBER: Package ball number(s) associated with each signal(s). 2. PIN NAME: The name of the package pin or terminal. Note: The table does not take into account subsystem terminal multiplexing options. 3. SIGNAL NAME: The signal name for that pin in the mode being used. 4. MODE: Multiplexing mode number. (a) Mode 0 is the primary mode; this means that when mode 0 is set, the function mapped on the terminal corresponds to the name of the terminal. There is always a function mapped on the primary mode. Notice that primary mode is not necessarily the default mode. AM3359, AM3358, AM3357 AM3356, AM3354, AM3352 SPRS717B – OCTOBER 2011 – REVISED JANUARY 2012 www.ti.com 9. POWER: The voltage supply that powers the terminal’s I/O buffers. 10. HYS: Indicates if the input buffer is with hysteresis. 11. BUFFER STRENGTH: Drive strength of the associated output buffer. 12. PULLUP/DOWN TYPE: Denotes the presence of an internal pullup or pulldown resistor. Pullup and pulldown resistors can be enabled or disabled via software. 13. I/O CELL: IO cell information. Note: Configuring two terminals to the same input signal is not supported as it can yield unexpected results. This can be easily prevented with the proper software configuration.

The oscillator is enabled by default after power is applied. (2) An external pull-down resistor should be connected to this terminal to minmize leakage current when not using the oscillator. (3) LCD_DATA[15:0] terminals are respectively SYSBOOT[15:0] inputs, latched on the rising edge of PWRONRSTn. (4) Reset Release Mode = 7 if sysboot[5] is low. Mode = 3 if sysboot[5] is high. (5) The internal USB PHY can be configured to multiplex the UART2_TX or UART2_RX signals to this terminal. For more details refer to USB GPIO Details section of the TRM. (6) The internal USB PHY can be configured to multiplex the UART3_TX or UART3_RX signals to this terminal. For more details refer to USB GPIO Details section of the TRM. (7) This terminal has an internal pull-down that remains on after reset is released if sysboot[5] is low on the rising edge or PWRONRSTn. This terminal will initially be driven low after reset is released if sysboot[5] is high on the rising edge or PWRONRSTn, then it begins to toggle at the same frequency of the XTALIN terminal. (8) This terminal has an internal pull-down turned on while reset is asserted. (9) This terminal is a analog input used to set the switching threshold of the DDR input buffers to (VDDS_DDR / 2). (10) This terminal is a analog passive signal that connects to an external 49.9 ohm 1%, 20mW reference resistor which is used to calibrate the DDR input/output buffers. (11) This terminal is analog input that may also be configured as an open-drain output. (12) This terminal is analog input that may also be configured as an open-source or open-drain output. (13) This terminal is analog input that may also be configured as an open-source output. (14) This terminal is high-Z when the oscillator is diasabled. This terminal is driven high if RTC_XTALIN is less than VIL, driven low if RTC_XTALIN is greater than VIH, and driven to a unknown value if RTC_XTALIN is between VIL and VIH when the oscillator is enabled. The oscillator is disabled by default after power is applied. (15) This terminal is high-Z when the oscillator is diasabled. This terminal is driven high if XTALIN is less than VIL, driven low if XTALIN is greater than VIH, and driven to a unknown value if XTALIN is between VIL and VIH when the oscillator is enabled. The oscillator is enabled by default after power is applied. (16) This terminal requires two power supplies, VDDA3P3v_USB0 and VDDA1P8v_USB0.

In order to reduce package size and cost while maintaining maximum functionality, many of the AM335x terminals can multiplex up to eight signal functions. Although there are many combinations of pin multiplexing that are possible, only a certain number of sets, called IO sets, are valid due to timing limitations. These valid IO sets were carefully chosen to provide many possible application scenarios for the user. PRODUCT PREVIEW Texas Instruments has developed a Windows application called Pin Mux Utility that helps a system designer select the appropriate pin-multiplexing configuration for their AM335x-based product design. This tool provides a way to select valid IO sets of specific peripheral interfaces to ensure that the pin-multiplexing configuration selected for a design only uses valid IO sets supported by the AM335x device.

Power-Supply Sequencing with RTC Feature Disabled 4.1.2 Power-Down Sequencing PWRONRSTn input terminal should be taken low, which stops all internal clocks before power supplies are turned off. All other external clocks to the device should be shut off. The preferred way to sequence power down is to have all the power supplies ramped down sequentially in the exact reverse order of the power-up sequencing. In other words, the power supply that has been ramped up first should be the last one that should be ramped down. This will ensure there would be no spurious current paths during the power-down sequence. The VDDS power supply must ramp down after all 3.3-V VDDSHVx [1-6] power supplies. If it is desired to ramp down VDDS and VDDSHVx [1-6] simultaneously, it should always be ensured that the difference between VDDS and VDDSHVx [1-6] during the entire power-down sequence is <2 V. If this is violated it can result in reliability risks for the device. Further, it should also be ensured that the VDDS supply should be ≥1.5 V of all the other supplies in the system during the ramp down. If there is no 3.3-V VDDSHVx [1-6] power supply, the VDDS power supply may ramp down at the same time or after all 1.8-V VDDSHVx[1-6] power supplies. It should be ensured that the VDDS supply should be ≥1.5 V of all the other supplies in the system during ramp down.

Each clock input passes through an internal oscillator which can be connected to an external crystal circuit (oscillator mode) or external LVCMOS square-wave digital clock source (bypass mode). The oscillators automatically operate in bypass mode when their input is connected to an external LVCMOS square-wave digital clock source. The oscillator associated with a specific clock input must be enabled when the clock input is being used in either oscillator mode or bypass mode. The OSC1 oscillator provides a 32.768-kHz reference clock to the real-time clock (RTC) and is connected to the RTC_XTALIN and RTC_XTALOUT terminals. This clock source is referred to as the 32K oscillator (CLK_32K_RTC) in the AM335x ARM Cortex-A8 Microprocessors (MPUs) Technical Reference Manual (literature number SPRUH73). OSC1 is disabled by default after power is applied. This clock input is optional and may not be required if the RTC is configured to receive a clock from the internal 32k RC oscillator (CLK_RC32K) or peripheral PLL (CLK_32KHZ) which receives a reference clock from the OSC0 input. PRODUCT PREVIEW The OSC0 oscillator provides a 19.2-MHz, 24-MHz, 25-MHz, or 26-MHz reference clock which is used to clock all non-RTC functions and is connected to the XTALIN and XTALOUT terminals. This clock source is referred to as the master oscillator (CLK_M_OSC) in the AM335x ARM Cortex-A8 Microprocessors (MPUs) Technical Reference Manual (literature number SPRUH73). OSC0 is enabled by default after power is applied. For more information related to recommended circuit topologies and crystal oscillator circuit requirements for these clock inputs, see Section 4.2.2. 4.2.2 Input Clock Requirements 4.2.2.1 OSC0 Internal Oscillator Clock Source Figure 4-6 shows the recommended crystal circuit. It is recommended that pre-production printed circuit board (PCB) designs include the two optional resistors Rbias and Rd in case they are required for proper oscillator operation when combined with production crystal circuit components. In most cases, Rbias will not be required and Rd will be a zero ohm resistor. These resistors may be removed from production PCB designs after evaluating oscillator performance with production crystal circuit components installed on pre-production PCBs. The XTALIN terminal has a 15 - 40 kΩ internal pull-down resistor which is enabled when OSC0 is disabled. This internal resistor prevents the XTALIN terminal from floating to an invalid logic level which may increase leakage current through the oscillator input buffer. 96 Power and Clocking Copyright © 2011–2012, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): AM3359 AM3358 AM3357 AM3356 AM3354 AM3352 AM3359, AM3358, AM3357 AM3356, AM3354, AM3352 SPRS717B – OCTOBER 2011 – REVISED JANUARY 2012 www.ti.com AM335x VSS_OSC XTALIN C1 XTALOUT C2 Optional Rbias Optional Rd Crystal B.

For more information related to configuring these clock output signals, see the CLKOUT Signals section of the AM335x ARM Cortex-A8 Microprocessors (MPUs) Technical Reference Manual (literature number SPRUH73). 4.2.4 Output Clock Characteristics 4.2.4.1 CLKOUT1 The CLKOUT1 signal can be output on the XDMA_EVENT_INTR0 terminal. This terminal connects to one of seven internal signals via configurable multiplexers. The XDMA_EVENT_INTR0 multiplexer must be configured for Mode 3 to connect the CLKOUT1 signal to the XDMA_EVENT_INTR0 terminal. The default reset configuration of the XDMA_EVENT_INTR0 multiplexer is selected by the logic level applied to the LCD_DATA5 terminal on the rising edge of PWRONRSTn. The XDMA_EVENT_INTR0 multiplexer will be configured to Mode 7 if the LCD_DATA5 terminal is low on the rising edge of PWRONRSTn or Mode 3 if the LCD_DATA5 terminal is high on the rising edge of PWRONRSTn. This allows the CLKOUT1 signal to be output on the XDMA_EVENT_INTR0 terminal without software intervention. In this mode, the output will be held low while PWRONRSTn is active and will begin to toggle after PWRONRSTn is released. 100 Power and Clocking Copyright © 2011–2012, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): AM3359 AM3358 AM3357 AM3356 AM3354 AM3352 AM3359, AM3358, AM3357 AM3356, AM3354, AM3352 SPRS717B – OCTOBER 2011 – REVISED JANUARY 2012 www.ti.com 4.2.4.2 CLKOUT2 The CLKOUT2 signal can be output on the XDMA_EVENT_INTR1 terminal.

Although there are many combinations of pin multiplexing that are possible, only a certain number of sets, called IO sets, are valid due to timing limitations. These valid IO sets were carefully chosen to provide many possible application scenarios for the user. Texas Instruments has developed a Windows application called Pin Mux Utility that helps a system designer select the appropriate pin-multiplexing configuration for their AM335x-based product design. This tool provides a way to select valid IO sets of specific peripheral interfaces to ensure that the pin-multiplexing configuration selected for a design only uses valid IO sets supported by the AM335x device. 5.1 5.1.1 Parameter Information Timing Parameters and Board Routing Analysis PRODUCT PREVIEW The timing parameter values specified in this data manual do not include delays by board routings. As a good board design practice, such delays must always be taken into account. Timing values may be adjusted by increasing/decreasing such delays. TI recommends utilizing the available I/O buffer information specification (IBIS) models to analyze the timing characteristics correctly. If needed, external logic hardware such as buffers may be used to compensate any timing differences. For the mDDR(LPDDR)/DDR2/DDR3 memory interface, it is not necessary to use the IBIS models to analyze timing characteristics. TI provides a PCB routing rules solution that describes the routing rules to ensure the mDDR(LPDDR)/DDR2/DDR3 memory interface timings are met. 5.2 Recommended Clock and Control Signal Transition Behavior All clocks and control signals must transition between VIH and VIL (or between VIL and VIH) in a monotonic manner. 102 Peripheral Information and Timings Copyright © 2011–2012, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): AM3359 AM3358 AM3357 AM3356 AM3354 AM3352 AM3359, AM3358, AM3357 AM3356, AM3354, AM3352 SPRS717B – OCTOBER 2011 – REVISED JANUARY 2012 www.ti.com 5.3 Ethernet Media Access Controller (EMAC)/Switch 5.3.1 Ethernet MAC/Switch Electrical Data/Timing The Ethernet MAC/Switch implemented in the AM335x device supports GMII mode, but the AM335x design does not pin out 9 of the 24 GMII signals. This was done to reduce the total number of package terminals. Therefore, the AM335x device does not support GMII mode. MII mode is supported with the remaining GMII signals. The AM335x ARM Cortex-A8 Microprocessors (MPUs) Technical Reference Manual (literature number SPRUH73) and this document may reference internal signal names when discussing peripheral input and output signals since many of the AM335x package terminals can be multiplexed to one of several peripheral signals. For example, the AM335x terminal names for port 1 of the Ethernet MAC/Switch have been changed from GMII to MII to indicate their Mode 0 function, but the internal signal is named GMII. However, documents that describe the Ethernet switch reference these signals by their internal signal name. For a cross-reference of internal signal names to terminal names, see Table 2-7. Operation of the Ethernet MAC/Switch is not supported for OPP50. Table 5-1.

LPDDR Memory Interface Clock Timing 5.4.2.1.2 LPDDR Interface This section provides the timing specification for the LPDDR interface as a PCB design and manufacturing specification. The design rules constrain PCB trace length, PCB trace skew, signal integrity, cross-talk, and signal timing. These rules, when followed, result in a reliable LPDDR memory system without the need for a complex timing closure process. For more information regarding the guidelines for using this LPDDR specification, see the Understanding TI’s PCB Routing Rule-Based DDR Timing Specification application report (literature number SPRAAV0). This application report provides generic guidelines and approach. All the specifications provided in the data manual take precedence over the generic guidelines and must be adhered to for a reliable LPDDR interface operation. 5.4.2.1.2.1 LPDDR Interface Schematic Figure 5-28 shows the schematic connections for 16-bit interface on AM335x device using one x16 LPDDR device.

The design rules constrain PCB trace length, PCB trace skew, signal integrity, cross-talk, and signal timing. These rules, when followed, result in a reliable DDR2 memory system without the need for a complex timing closure process. For more information regarding the guidelines for using this DDR2 specification, see the Understanding TI’s PCB Routing Rule-Based DDR Timing Specification application report (literature number SPRAAV0).

Placement of serial terminations for ADDR_CTRL net class signals should be close to the AM335x device. Table 5-46 shows the specifications for the serial terminators in such cases. Table 5-46.

(8) An HS bypass capacitor may share a via with a DDR3 device mounted on the same side of the PCB. A wide trace should be used for the connection and the length from the capacitor pad to the DDR3 device pad should be less than 150 mils. (9) Up to a total of two pairs of DDR3 power/ground terminals may share a via. 5.4.2.3.3.7.1 Return Current Bypass Capacitors Use additional bypass capacitors if the return current reference plane changes due to DDR3 signals hopping from one signal layer to another. The bypass capacitor here provides a path for the return current to hop planes along with the signal. As many of these return current bypass capacitors should be used as possible.

PRODUCT PREVIEW 5.4.2.3.3.10 DDR_VREF Routing DDR_VREF is used as a reference by the input buffers of the DDR3 memories as well as the AM335x device. DDR_VREF is intended to be half the DDR3 power supply voltage and is typically generated with a voltage divider connected to the VDDS_DDR power supply. It should be routed as a nominal 20-mil wide trace with 0.1 µF bypass capacitors near each device connection. Narrowing of DDR_VREF is allowed to accommodate routing congestion. 5.4.2.3.3.11 VTT Like DDR_VREF, the nominal value of the VTT supply is half the DDR3 supply voltage. Unlike DDR_VREF, VTT is expected to source and sink current, specifically the termination current for the ADDR_CTRL net class Thevinen terminators. VTT is needed at the end of the address bus and it should be routed as a power sub-plane. VTT should be bypassed near the terminator resistors. 5.4.2.3.4 DDR3 CK and ADDR_CTRL Topologies and Routing Definition The CK and ADDR_CTRL net classes are routed similarly and are length matched to minimize skew between them. CK is a bit more complicated because it runs at a higher transition rate and is differential.

The only way to practically match lengths on a PCB is to lengthen the shorter traces up to the length of the longest net in the net class and its associated clock. A metric to establish this maximum length is Manhattan distance. The Manhattan distance between two points on a PCB is the length between the points when connecting them only with horizontal or vertical segments. A reasonable trace route length is to within a percentage of its Manhattan distance. CACLM is defined as Clock Address Control Longest Manhattan distance. (A) A1 A8 PRODUCT PREVIEW Given the clock and address pin locations on the AM335x device and the DDR3 memories, the maximum possible Manhattan distance can be determined given the placement. Figure 5-60 shows this distance for two loads. It is from this distance that the specifications on the lengths of the transmission lines for the address bus are determined. CACLM is determined similarly for other address bus configurations; i.e., it is based on the longest net of the CK/ADDR_CTRL net class. For CK and ADDR_CTRL routing, these specifications are contained in Table 5-59. CACLMY CACLMX A8 (A) A8 (A) Rtt A3 = A. AT Vtt AS A2 It is very likely that the longest CK/ADDR_CTRL Manhattan distance will be for Address Input 8 (A8) on the DDR3 memories. CACLM is based on the longest Manhattan distance due to the device placement. Verify the net class that satisfies this criteria and use as the baseline for CK/ADDR_CTRL skew matching and length control. The length of shorter CK/ADDR_CTRL stubs as well as the length of the terminator stub are not included in this length calculation. Non-included lengths are grayed out in the figure. Assuming A8 is the longest, CALM = CACLMY + CACLMX + 300 mils. The extra 300 mils allows for routing down lower than the DDR3 memories and returning up to reach A8. Figure 5-60.

(14) Termination values should be uniform across the net class. 5.4.2.3.6.2 DQS[x] and DQ[x] Routing Specification Skew within the DQS[x] and DQ[x] net classes directly reduces setup and hold margin and, thus, this skew must be controlled. The only way to practically match lengths on a PCB is to lengthen the shorter traces up to the length of the longest net in the net class and its associated clock. DQLMn is defined as DQ Longest Manhattan distance n, where n is the byte number. For a 16-bit interface, there are two DQLMs, DQLM0-DQLM1. NOTE It is not required, nor is it recommended, to match the lengths across all bytes. Length matching is only required within each byte. Given the DQS[x] and DQ[x] pin locations on the AM335x device and the DDR3 memories, the maximum possible Manhattan distance can be determined given the placement. Figure 5-61 shows this distance for a two-load case. It is from this distance that the specifications on the lengths of the transmission lines for the data bus are determined.

Each controller operates independently from the other and only one of them is active at any given time. • The raster controller handles the synchronous LCD interface. It provides timing and data for constant graphics refresh to a passive display. It supports a wide variety of monochrome and full-color display types and sizes by use of programmable timing controls, a built-in palette, and a gray-scale/serializer. Graphics data is processed and stored in frame buffers. A frame buffer is a contiguous memory block in the system. A built-in DMA engine supplies the graphics data to the raster engine which, in turn, outputs to the external LCD device. • The LIDD controller supports the asynchronous LCD interface. It provides full-timing programmability of control signals (CS, WE, OE, ALE) and output data. The maximum resolution for the LCD controller is 2048 x 2048 pixels. The maximum frame rate is determined by the image size in combination with the pixel clock rate. Table 5-61.

The tool's support documentation is electronically available within the Code Composer Studio™ Integrated Development Environment (IDE). The following products support development of AM335x device applications: Software Development Tools: Code Composer Studio™ Integrated Development Environment (IDE): including Editor C/C++/Assembly Code Generation, and Debug plus additional development tools Scalable, Real-Time Foundation Software (DSP/BIOS™), which provides the basic run-time target software needed to support any AM335x device application. DSP/BIOS™ Hardware Development Tools: Extended Development System (XDS™) Emulator XDS™ PRODUCT PREVIEW For a complete listing of development-support tools for the AM335x microprocessor platform, visit the Texas Instruments website at www.ti.com. For information on pricing and availability, contact the nearest TI field sales office or authorized distributor. 6.1.2 Device Nomenclature To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all microprocessors (MPUs) and support tools. Each device has one of three prefixes: X, P, or null (no prefix) (e.g., XAM3358ZCE). Texas Instruments recommends two of three possible prefix designators for its support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development from engineering prototypes (TMDX) through fully qualified production devices/tools (TMDS). Device development evolutionary flow: X Experimental device that is not necessarily representative of the final device's electrical specifications and may not use production assembly flow. P Prototype device that is not necessarily the final silicon die and may not necessarily meet final electrical specifications. null Production version of the silicon die that is fully qualified. Support tool development evolutionary flow: TMDX Development-support product that has not yet completed Texas Instruments internal qualification testing. TMDS Fully-qualified development-support product. X and P devices and TMDX development-support tools are shipped against the following disclaimer: "Developmental product is intended for internal evaluation purposes." Production devices and TMDS development-support tools have been characterized fully, and the quality and reliability of the device have been demonstrated fully. TI's standard warranty applies. Predictions show that prototype devices (X or P) have a greater failure rate than the standard production devices. Texas Instruments recommends that these devices not be used in any production system because their expected end-use failure rate still is undefined. Only qualified production devices are to be used. 188 Device and Documentation Support Copyright © 2011–2012, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): AM3359 AM3358 AM3357 AM3356 AM3354 AM3352 AM3359, AM3358, AM3357 AM3356, AM3354, AM3352 SPRS717B – OCTOBER 2011 – REVISED JANUARY 2012 www.ti.com TI device nomenclature also includes a suffix with the device family name.

Thermal Resistance Characteristics (PBGA Package) [ZCE and ZCZ] m/s = meters per second. °C/W = degress celsius per watt. The board types are defined by JEDEC (reference JEDEC standard JESD51-9, Test Board for Area Array Surface Mount Package Thermal Measurements). Via Channel The ZCE package has been specially engineered with Via Channel™ technology. This allows larger than normal PCB via and trace sizes and reduced PCB signal layers to be used in a PCB design with the 0.65-mm pitch package, and substantially reduces PCB costs. It allows PCB routing in only two signal layers (four layers total) due to the increased layer efficiency of the Via Channel™ BGA technology. Via Channel™ technology implemented on the ZCE package makes it possible to build an AM335x-based product with a 4-layer PCB, but a 4-layer PCB may not meet system performance goals. Therefore, system performance using a 4-layer PCB design must be evaluated during product design. 7.3 Packaging Information The following packaging information and addendum reflect the most current data available for the designated device(s). This data is subject to change without notice and without revision of this document. The figures below show the package drawings for the ZCE and ZCZ package options.

Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed. TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and applications using TI components. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications. TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
