November 2002 − Revised August 2003 SPRS205A 1 Introduction 2 Introduction This section describes the main features of the TMS320VC5509A, lists the pin assignments, and describes the function of each pin. This data manual also provides a detailed description section, electrical specifications, parameter measurement information, and mechanical data about the available packaging. NOTE: This data manual is designed to be used in conjunction with theTMS320C55x DSP Functional Overview (literature number SPRU312), the TMS320C55x DSP CPU Reference Guide (literature number SPRU371), and the TMS320C55x DSP Peripherals Overview Reference Guide (literature number SPRU317). 2.1 Description The TMS320VC5509A fixed-point digital signal processor (DSP) is based on the TMS320C55x DSP generation CPU processor core. The C55x DSP architecture achieves high performance and low power through increased parallelism and total focus on reduction in power dissipation. The CPU supports an internal bus structure that is composed of one program bus, three data read buses, two data write buses, and additional buses dedicated to peripheral and DMA activity. These buses provide the ability to perform up to three data reads and two data writes in a single cycle. In parallel, the DMA controller can perform up to two data transfers per cycle independent of the CPU activity. PRODUCT PREVIEW The C55x CPU provides two multiply-accumulate (MAC) units, each capable of 17-bit x 17-bit multiplication in a single cycle. A central 40-bit arithmetic/logic unit (ALU) is supported by an additional 16-bit ALU. Use of the ALUs is under instruction set control, providing the ability to optimize parallel activity and power consumption. These resources are managed in the Address Unit (AU) and Data Unit (DU) of the C55x CPU. The C55x DSP generation supports a variable byte width instruction set for improved code density. The Instruction Unit (IU) performs 32-bit program fetches from internal or external memory and queues instructions for the Program Unit (PU). The Program Unit decodes the instructions, directs tasks to AU and DU resources, and manages the fully protected pipeline. Predictive branching capability avoids pipeline flushes on execution of conditional instructions. The general-purpose input and output functions and the10-bit A/D provide sufficient pins for status, interrupts, and bit I/O for LCDs, keyboards, and media interfaces. The parallel interface operates in two modes, either as a slave to a microcontroller using the HPI port or as a parallel media interface using the asynchronous EMIF. Serial media is supported through two MultiMedia Card/Secure Digital (MMC/SD) peripherals and three McBSPs. The 5509A peripheral set includes an external memory interface (EMIF) that provides glueless access to asynchronous memories like EPROM and SRAM, as well as to high-speed, high-density memories such as synchronous DRAM. Additional peripherals include Universal Serial Bus (USB), real-time clock, watchdog timer, I2C multi-master and slave interface, and a unique device ID. Three full-duplex multichannel buffered serial ports (McBSPs) provide glueless interface to a variety of industry-standard serial devices, and multichannel communication with up to 128 separately enabled channels. The enhanced host-port interface (HPI) is a 16-bit parallel interface used to provide host processor access to 32K bytes of internal memory on the 5509A. The HPI can be configured in either multiplexed or non-multiplexed mode to provide glueless interface to a wide variety of host processors. The DMA controller provides data movement for six independent channel contexts without CPU intervention, providing DMA throughput of up to two 16-bit words per cycle. Two general-purpose timers, up to eight dedicated general-purpose I/O (GPIO) pins, and digital phase-locked loop (DPLL) clock generation are also included. The 5509A is supported by the industry’s award-winning eXpressDSP, Code Composer Studio Integrated Development Environment (IDE), DSP/BIOS, Texas Instruments’ algorithm standard, and the industry’s largest third-party network. The Code Composer Studio IDE features code generation tools including a C Compiler and Visual Linker, simulator, RTDX, XDS510 emulation device drivers, and evaluation modules. The 5509A is also supported by the C55x DSP Library which features more than 50 foundational software kernels (FIR filters, IIR filters, FFTs, and various math functions) as well as chip and board support libraries. C55x, eXpressDSP, Code Composer Studio, DSP/BIOS, RTDX, and XDS510 are trademarks of Texas Instruments. 2 SPRS205A November 2002 − Revised August 2003 Introduction The TMS320C55x DSP core was created with an open architecture that allows the addition of application-specific hardware to boost performance on specific algorithms. The hardware extensions on the 5509A strike the perfect balance of fixed function performance with programmable flexibility, while achieving low-power consumption, and cost that traditionally has been difficult to find in the video-processor market. The extensions allow the 5509A to deliver exceptional video codec performance with more than half its bandwidth available for performing additional functions such as color space conversion, user-interface operations, security, TCP/IP, voice recognition, and text-to-speech conversion. As a result, a single 5509A DSP can power most portable digital video applications with processing headroom to spare. For more information, see the TMS320C55x Hardware Extensions for Image/Video Applications Programmer’s Reference (literature number SPRU098). For more information on using the the DSP Image Processing Library, see the TMS320C55x Image/Video Processing Library Programmer’s Reference (literature number SPRU037). 2.2 Pin Assignments DVDD is the power supply for the I/O pins while CVDD is the power supply for the core.

The total on-chip memory is 320K bytes (128K 16-bit words of RAM and 32K 16-bit words of ROM). 3.1.1 On-Chip Dual-Access RAM (DARAM) The DARAM is located in the byte address range 000000h−00FFFFh and is composed of eight blocks of 8K bytes each (see Table 3−1). Each DARAM block can perform two accesses per cycle (two reads, two writes, or a read and a write). DARAM can be accessed by the internal program, data, or DMA buses. The HPI can only access the first four (32K bytes) DARAM blocks. PRODUCT PREVIEW Table 3−1.

The ROM is composed of one block of 32K bytes and two 16K-byte blocks, for a total of 64K bytes of ROM. The ROM address space can be mapped by software to the external memory or to the internal ROM. The 16K ROM blocks at FFC000 to FFFFFF can be configured as secure ROM. (See Section 3.1.4.) NOTE: Customers can arrange to have the 5509A ROM programmed with contents unique to any particular application. Contact your local Texas Instruments representative for more information on custom ROM programming. 3.1.4 Secure ROM Included in this 64K-byte ROM is a 16K-byte secure ROM (SROM) that is mapped into the memory space at reset. This 16K-byte SROM is mapped out of the memory space by writing a “1” to the SROM disable bit field of the Secure ROM Register (0x7C00) as shown in Figure 3−2. When the SROM disable bit is set, its setting cannot be changed and the CPU or peripherals cannot access the on-chip SROM memory space. This ROM block is not programmed on standard 5509A devices, but can be used to implement a custom, secure bootload feature. Contact your local Texas Instruments representative for more information on custom ROM programming.

Secure ROM November 2002 − Revised August 2003 SPRS205A 21 PRODUCT PREVIEW The standard 5509A device includes a bootloader program resident in the ROM. When the MPNMC bit field of the ST3 status register is set through software, the on-chip ROM is disabled and not present in the memory map, and byte address range FF0000h−FFFFFFh is directed to external memory space. A hardware reset always clears the MPNMC bit, so it is not possible to disable the ROM at reset. However, the software reset instruction does not affect the MPNMC bit. All three ROM blocks can be accessed by the program, data, or DMA buses. The first 16-bit word access to ROM requires three cycles. Subsequent accesses require two cycles per 16-bit word. Functional Overview 3.1.5 Memory Map The 5509A provides 16M bytes of total memory space composed of on-cip RAM, on-chip ROM, and external memory space supporting a variety of memory types. The on-chip, dual-access RAM allows two accesses to a given block during the same cycle. The 5509A supports 8 blocks of 8K bytes of dual-access RAM. The on-chip, single-access RAM allows one access to a given block per clock cycle. The 5509A supports 24 blocks of 8K byte of single-access RAM. PRODUCT PREVIEW The remainder of the memory map is external space that is divided into four spaces. Each space has a chip enable decode signal (called CE) that indicates an access to the selected space. The External Memory Interface (EMIF) supports access to asynchronous memories such as SRAM and Flash, and synchronous DRAM. 22 SPRS205A November 2002 − Revised August 2003 Functional Overview 3.1.5.1 PGE Package Memory Map The PGE package features 14 address bits representing 16K-byte linear address for asynchronous memories per CE space.

Sync events are selected by programming the SYNC field in the channel-specific DMA Channel Control Register (DMA_CCR). 26 SPRS205A November 2002 − Revised August 2003 Functional Overview 3.3.1 DMA Channel Control Register (DMA_CCR) The channel control register (DMA_CCR) bit layouts are shown in Figure 3−5. 15 14 13 12 11 10 9 8 DST AMODE SRC AMODE END PROG Reserved REPEAT AUTO INIT R/W, 00 R/W, 00 R/W, 0 R, 0 R/W, 0 R/W, 0 7 6 5 EN PRIO FS 4 SYNC 0 R/W, 0 R/W, 0 R/W, 0 R/W, 00000 LEGEND: R = Read, W = Write, n = value after reset The SYNC[4:0] bits specify the event that can initiate the DMA transfer for the corresponding DMA channel.

The I2C port supports: • • • • • Compatible with Philips I2C Specification Revision 2.1 (January 2000) Operates at 100 Kbps or 400 Kbps 7-bit addressing mode Master (transmit/receive) and slave (transmit/receive) modes of operation Events: DMA, interrupt, or polling The I2C module clock must be in the range from 7 MHz to 12 MHz. This is necessary for proper operation of the I2C module. With the I2C module clock in this range, the noise filters on the SDA and SCL pins suppress noise that has a duration of 50 ns or shorter. The I2C module clock is derived from the DSP clock divided by a programmable prescaler. NOTE: I/O buffers are not fail-safe. The SDA and SCL pins could potentially draw current if the device is powered down and SDA and SCL are driven by other devices connected to the I2C bus. 3.5 Configurable External Buses The 5509A offers several combinations of configurations for its external parallel port and two serial ports. This allows the system designer to choose the appropriate media interface for its application without the need of a large-pin-count package. The External Bus Selection Register controls the routing of the parallel and serial port signals. 28 SPRS205A November 2002 − Revised August 2003 Functional Overview 3.5.1 External Bus Selection Register (EBSR) The External Bus Selection Register determines the mapping of the 14 (LQFP) or 21 (BGA) address signals, 16 data signals, and 15 control signals of the external parallel port. It also determines the mapping of the McBSP or MMC/SD ports to Serial Port1 and Serial Port2. The External Bus Selection Register is memory-mapped at port address 0x6C00. Once the bit fields of this register are changed, the routing of the signals takes place on the next CPU clock cycle. 15 14 13 12 11 10 9 8 CLKOUT Disable OSC Disable HIDL BKE SR STAT HOLD HOLDA CKE SEL R/W, 0 R/W, 0 R/W, 0 R, 0 R/W, 0 R/W, 0 R/W, 1 R/W, 0 7 6 5 4 3 2 1 0 CKE EN SR CMD Serial Port2 Mode R/W, 0 R/W, 0 R/W, 00 Serial Port1 Mode Parallel Port Mode R/W, 00 R/W, 01 if GPIO0 = 1 11 if GPIO0 = 0 PRODUCT PREVIEW The reset value of the parallel port mode bit field is determined by the state of the GPIO0 pin at reset.

HIDL = 0: HIDL = 1: Host access to DSP enabled. Idling EHPI and clock domain is not allowed. Idles the HPI and the clock domain upon execution of the IDLE instruction when the parallel port mode is set to 10 or 11 selecting HPI mode.

Each pin can be indepedently configured as an input or an output using the I/O Direction Register (IODIR). The I/O Data Register (IODATA) is used to monitor the logic state of pins configured as inputs and control the logic state of pins configured as outputs. See Table 3−28 for address information. The description of the IODIR is shown in Figure 3−9 and Table 3−9. The description of IODATA is shown in Figure 3−10 and Table 3−10. To configure a GPIO pin as an input, clear the direction bit that corresponds to the pin in IODIR to 0. To read the logic state of the input pin, read the corresponding bit in IODATA. To configure a GPIO pin as an output, set the direction bit that corresponds to the pin in IODIR to 1.

Some registers use less than 16 bits. When reading these registers, unused bits are always read as 0. NOTE: The CPU access latency to the peripheral memory-mapped registers is 6 CPU cycles. Following peripheral register update(s), the CPU must wait at least 6 CPU cycles before attempting to use that peripheral. When more than one peripheral register is updated in a sequence, the CPU only needs to wait following the final register write. For example, if the EMIF is being reconfigured, the CPU must wait until the very last EMIF register update takes effect before trying to access the external memory. The users should consult the respective peripheral user’s guide to determine if a peripheral requires additional time to initialize itself to the new configuration after the register updates take effect.

Interrupt vectors for interrupts 0−15 and 24−31 are relative to IVPD. Interrupt vectors for interrupts 16−23 are relative to IVPH. ‡ The NMI pin is internally tied high. However, NMI interrupt vector can be used for SINT1 and Watchdog Timer Interrupt. § It is recommended that either the INT4 or RTC interrupt be used. If both INT4 and RTC interrupts are used, one interrupt event can potentially hold off the other interrupt. For example, if INT4 is asserted first and held low, the RTC interrupt will not be recognized until the INT4 pin is back to high-logic state again. The INT4 pin must be pulled high if only the RTC interrupt is used. 60 SPRS205A November 2002 − Revised August 2003 Functional Overview 3.10.1 IFR and IER Registers The IFR0 (Interrupt Flag Register 0) and IER0 (Interrupt Enable Register 0) bit layouts are shown in Figure 3−18. 15 14 13 12 11 10 9 8 DMAC5 DMAC4 XINT2/ MMCSD2 RINT2 INT3/ WDTINT DSPINT DMAC1 USB R/W R/W R/W R/W R/W R/W R/W R/W 7 6 5 4 3 2 1 0 XINT1/ MMCSD1 RINT1 RINT0 TINT0 INT2 INT0 R/W R/W R/W R/W R/W R/W PRODUCT PREVIEW NOTE: Some of the interrupts are shared between multiple interrupt sources. All sources for a particular bit are internally combined using a logic OR function so that no additional user configuration is required to select the interrupt source. In the case of the serial port, the shared functions are mutually exclusive so that only one of the interrupt sources will be active at a time in a given system. For example: It is not possible to use McBSP2 and MMC/SD2 simultaneously. However, in the case of INT3/WDTINT it is possible to have active interrupts simultaneously from both the external INT3 source and the watchdog timer. When an interrupt is detected in this bit, the watchdog timer status register should be polled to determine if the watchdog timer is the interrupt source.

The interrupt inputs are sampled on falling edges of the CPU clock. A sequence of 1-1-0-0-0 on consecutive cycles on the interrupt pin is required for an interrupt to be detected. Therefore, the minimum low pulse duration on the external interrupts on the 5509A is three CPU clock periods. 3.10.3 Waking Up From IDLE Condition One of the following four events can wake up the CPU from IDLE: • Hardware Reset • External Interrupt • RTC Interrupt • USB Event (Reset or Resume) With an external interrupt, a RTC interrupt, or an USB resume/reset, the clock generation circuit wakes up the oscillator and enables the USB PLL to determine the oscillator stable time. In the case of the interrupt being disabled by clearing the associated bit in the Interrupt Enable Register (IERx), the CPU is not “woken up”. If the interrupt due to the wake-up event is enabled, the interrupt is sent to the CPU only after the oscillator is stabilized and the USB PLL is locked. If the external interrupt serves as the wake-up event, the interrupt line must stay low for a minimum of 3 CPU cycles after the oscillator is stabilized to wake up the CPU. Otherwise, only the clock domain will wake up and another external interrupt will be needed to wake up the CPU. Once out of IDLE, any system not using the USB should put the USB module in idle mode to reduce power consumption. For more details on the TMS320VC5509A oscillator-disable process, see the Disabling the Internal Oscillator With External Crystal on the TMS320VC5509 DSP application report (literature number SPRA078). 3.10.4 Idling Clock Domain When External Parallel Bus Operating in EHPI Mode The clock domain cannot be idled when the External Parallel Bus is operating in EHPI mode to ensure host access to the DSP memory. To work around this restriction, use the HIDL bit of the External Bus Selection Register (EBSR) with the CLKGENI bit of the Idle Control Register (ICR) to idle the clock domain.

Each TMS320 DSP commercial family member has one of three prefixes: TMX, TMP, or TMS. Texas Instruments recommends two of three possible prefix designators for support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development from engineering prototypes (TMX / TMDX) through fully qualified production devices/tools (TMS / TMDS). Device development evolutionary flow: TMX Experimental device that is not necessarily representative of the final device’s electrical specifications TMP Final silicon die that conforms to the device’s electrical specifications but has not completed quality and reliability verification TMS Fully qualified production device TMDX Development-support product that has not yet completed Texas Instruments internal qualification testing. TMDS Fully qualified development-support product TMX and TMP devices and TMDX development-support tools are shipped with appropriate disclaimers describing their limitations and intended uses. Experimental devices (TMX) may not be representative of a final product and Texas Instruments reserves the right to change or discontinue these products without notice. TMS 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 ( TMX or TMP) 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.

The oscillator requires an external crystal or ceramic resonator connected across the X1 and X2/CLKIN pins. If the internal oscillator is not used, an external clock source must be applied to the X2/CLKIN pin and the X1 pin should be left unconnected. Since the internal oscillator can be used as a clock source to the PLLs, the crystal oscillation frequency can be multiplied to generate the CPU clock and USB clock, if desired. The crystal should be in fundamental-mode operation, and parallel resonant, with a maximum effective series resistance (ESR) specified in Table 5−2. The connection of the required circuit is shown in Figure 5−2. Under some conditions, all the components shown are not required. The capacitors, C1 and C2, should be chosen such that the equation below is satisfied. CL in the equation is the load specified for the crystal that is also specified in Table 5−2.

It is recommended that crystals which meet the maximum ESR specification in Table 5−2 are used. 72 SPRS205A November 2002 − Revised August 2003 Electrical Specifications 5.6.2 Layout Considerations PRODUCT PREVIEW Since parasitic capacitance, inductance and resistance can be significant in any circuit, good PC board layout practices should always be observed when planning trace routing to the discrete components used in the oscillator circuit. Specifically, the crystal and the associated discrete components should be located as close to the DSP as physically possible. Also, X1 and X2/CLKIN traces should be separated as soon as possible after routing away from the DSP to minimize parasitic capacitance between them, and a ground trace should be run between these two signal lines. This also helps to minimize stray capacitance between these two signals. November 2002 − Revised August 2003 SPRS205A 73 Electrical Specifications 5.6.3 Clock Generation in Bypass Mode (DPLL Disabled) The frequency of the reference clock provided at the X2/CLKIN pin can be divided by a factor of one, two, or four to generate the internal CPU clock cycle. The divide factor (D) is set in the BYPASS_DIV field of the clock mode register. The contents of this field only affect clock generation while the device is in bypass mode. In this mode, the digital phase-locked loop (DPLL) clock synthesis is disabled. Table 5−3 and Table 5−4 assume testing over recommended operating conditions and H = 0.5tc(CO) (see Figure 5−3).
