The SMJ320C6701 (’C6701) device is based on the high-performance, advanced VelociTI™ very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI), making this DSP an excellent choice for multichannel and multifunction applications. With performance of up to 1 giga floating-point operations per second (GFLOPS) at a clock rate of 140 MHz, the ’C6701 offers cost-effective solutions to high-performance DSP programming challenges. The ’C6701 DSP possesses the operational flexibility of high-speed controllers and the numerical capability of array processors. This processor has 32 general-purpose registers of 32-bit word length and eight highly independent functional units. The eight functional units provide four floating-/fixed-point ALUs, two fixedpoint ALUs, and two floating-/fixed-point multipliers. The ’C6701 can produce two multiply-accumulates (MACs) per cycle for a total of 334 million MACs per second (MMACS). The ’C6701 DSP also has application-specific hardware logic, on-chip memory, and additional on-chip peripherals. The ’C6701 includes a large bank of on-chip memory and has a powerful and diverse set of peripherals. Program memory consists of a 64K-byte block that is user-configurable as cache or memory-mapped program space. Data memory consists of two 32K-byte blocks of RAM. The peripheral set includes two multichannel buffered serial ports (McBSPs), two general-purpose timers, a host-port interface (HPI), and a glueless external memory interface (EMIF) capable of interfacing to SDRAM or SBSRAM and asynchronous peripherals. The ’C6701 has a complete set of development tools that includes a new C compiler, an assembly optimizer to simplify programming and scheduling, and a Windows™ debugger interface for visibility into source code execution. 2 Submit Documentation Feedback Copyright © 2000–2013, Texas Instruments Incorporated Product Folder Links: SMJ320C6701-SP SMJ320C6701-SP www.ti.com SGUS030F – APRIL 2000 – REVISED SEPTEMBER 2013 Device Characteristics Table 1 provides an overview of the ’C6701 DSP.

The VelociTI VLIW architecture features controls by which all eight units do not have to be supplied with instructions if they are not ready to execute. The first bit of every 32-bit instruction determines if the next instruction belongs to the same execute packet as the previous instruction, or whether it should be executed in the following clock as a part of the next execute packet. Fetch packets are always 256 bits wide; however, the execute packets can vary in size. The variable-length execute packets are a key memory-saving feature, distinguishing the ’C67x CPU from other VLIW architectures. The CPU features two sets of functional units. Each set contains four units and a register file. One set contains functional units .L1, .S1, .M1, and .D1; the other set contains units .D2, .M2, .S2, and .L2. The two register files contain 16 32-bit registers each for the total of 32 general-purpose registers. The two sets of functional units, along with two register files, compose sides A and B of the CPU (see the functional and CPU block diagram and Figure 1). The four functional units on each side of the CPU can freely share the 16 registers belonging to that side. Additionally, each side features a single data bus connected to all registers on the other side, by which the two sets of functional units can access data from the register files on opposite sides. While register access by functional units on the same side of the CPU as the register file can service all the units in a single clock cycle, register access using the register file across the CPU supports one read and one write per cycle. The ’C67x CPU executes all ’C62x instructions. In addition to ’C62x fixed-point instructions, the six out of eight functional units (.L1, .M1, .D1, .D2, .M2, and .L2) also execute floating-point instructions. The remaining two functional units (.S1 and .S2) also execute the new LDDW instruction which loads 64 bits per CPU side for a total of 128 bits per cycle. Another key feature of the ’C67x CPU is the load/store architecture, where all instructions operate on registers (as opposed to data in memory). Two sets of data-addressing units (.D1 and .D2) are responsible for all data transfers between the register files and the memory. The data address driven by the .D units allows data addresses generated from one register file to be used to load or store data to or from the other register file. The ’C67x CPU supports a variety of indirect-addressing modes using either linear- or circular-addressing modes with 5- or 15-bit offsets. All instructions are conditional, and most can access any one of the 32 registers. Some registers, however, are singled out to support specific addressing or to hold the condition for conditional instructions (if the condition is not automatically "true"). The two .M functional units are dedicated for multiplies. The two .S and .L functional units perform a general set of arithmetic, logical, and branch functions with results available every clock cycle. The processing flow begins when a 256-bit-wide instruction fetch packet is fetched from a program memory. The 32-bit instructions destined for the individual functional units are "linked" together by "1" bits in the least significant bit (LSB) position of the instructions. The instructions that are "chained" together for simultaneous execution (up to eight in total) compose an execute packet. A "0" in the LSB of an instruction breaks the chain, effectively placing the instructions that follow it in the next execute packet. If an execute packet crosses the fetch-packet boundary (256 bits wide), the assembler places it in the next fetch packet, while the remainder of the current fetch packet is padded with NOP instructions. The number of execute packets within a fetch packet can vary from one to eight. Execute packets are dispatched to their respective functional units at the rate of one per clock cycle and the next 256-bit fetch packet is not fetched until all the execute packets from the current fetch packet have been dispatched. After decoding, the instructions simultaneously drive all active functional units for a maximum execution rate of eight instructions every clock cycle. While most results are stored in 32-bit registers, they can be subsequently moved to memory as bytes or half-words as well. All load and store instructions are byte, half-word, or word addressable. 4 Submit Documentation Feedback Copyright © 2000–2013, Texas Instruments Incorporated Product Folder Links: SMJ320C6701-SP SMJ320C6701-SP www.ti.com ÁÁÁÁ Á ÁÁÁÁ Á ÁÁÁÁ Á Á ÁÁÁÁ Á ÁÁÁÁ Á ÁÁÁÁ Á ÁÁÁÁ Á ÁÁÁÁ ÁÁÁÁ Á ÁÁÁÁ Á ÁÁÁÁ Á Á ÁÁÁÁ Á ÁÁÁÁ Á ÁÁÁÁ ÁÁÁÁ Á ÁÁÁÁ Á ÁÁÁÁ Á ÁÁÁÁ Á ÁÁÁÁ Á ÁÁÁÁ Á ÁÁÁÁ Á ÁÁÁÁ Á Á ÁÁÁÁ Á ÁÁÁÁ Á ÁÁÁÁ Á ÁÁÁÁ ÁÁÁÁ Á ÁÁÁÁ Á Á ÁÁÁÁ Á ÁÁÁÁ ÁÁÁÁ ÁÁÁÁ Á ÁÁÁÁ Á Á ÁÁÁÁ Á ÁÁÁÁ Á ÁÁÁÁ ÁÁÁÁ src1 .L1(1) src2 dst long dst long src LD1 32 MSB ST1 8 long src long dst dst (1) .S1 src1 Data Path A 8 32 8 ÁÁ ÁÁ ÁÁ ÁÁ ÁÁ ÁÁ LD1 32 LSB DA1 DA2 LD2 32 LSB dst src1 src2 .D1 .D2 dst src1 src2 1X Á Á Á Á Á Á src2 src1 dst src1 dst src2 Data Path B ÁÁ ÁÁ ÁÁ LD2 32 MSB ST2 src1 .S2(1) dst long dst long src long src long dst dst .L2(1) src2 src1 (1) Register File A (A0−A15) 2X src2 .M2(1) Á Á Á Á Á Á Á 32 8 src2 .M1(1) Á Á Á Á Á ÁÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁÁ ÁÁ ÁÁÁÁÁ ÁÁ ÁÁ SGUS030F – APRIL 2000 – REVISED SEPTEMBER 2013 Register File B (B0−B15) 8 8 8 Á Á Á Á Á Á 32 32 8 These functional units execute floating-point instructions.

Each SMJ320 member has one of three prefixes: SMX, SM, or SMJ. 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 (SMX/TMDX) through fully qualified production devices/tools (SMJ/TMDS). Device development evolutionary flow: SMX Experimental device that is not necessarily representative of the final device’s electrical specifications SM Final silicon die that conforms to the device’s electrical specifications but has not completed quality and reliability verification SMJ Fully qualified production device processed to MIL-PRF-38535 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 SMX devices and TMDX development-support tools are shipped against the following disclaimer: "Developmental product is intended for internal evaluation purposes." SMJ 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 (SMX or SM) 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. TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type (for example, GLP), the temperature range, and the device speed range in megahertz (for example, 14 is 140 MHz). Figure 4 provides a legend for reading the complete device name for any SMJ320 family member. 22 Submit Documentation Feedback Copyright © 2000–2013, Texas Instruments Incorporated Product Folder Links: SMJ320C6701-SP SMJ320C6701-SP www.ti.com SGUS030F – APRIL 2000 – REVISED SEPTEMBER 2013 SMJ 320 C 6701 GLP W 14 PREFIX SMX= Experimental device SMJ = MIL-PRF-38535, QML SM = Commercial processing DEVICE FAMILY 320 = SMJ320 family TECHNOLOGY C = CMOS -SP RAD-TOLERANT CLASS V DEVICE SPEED RANGE 14 = 140 MHz TEMPERATURE RANGE (DEFAULT: 0°C TO 90°C) W = -55 °C to 115°C, extended temperature PACKAGE TYPE (1) GLP = 429-pin ceramic BGA ZMB = 429-pin ceramic LGA DEVICE ’6x DSP: 6201B 6203 6701 (1) BGA = Ball grid array Figure 4.

Clock PLL All of the internal ’C67x clocks are generated from a single source through the CLKIN pin. This source clock either drives the PLL, which multiplies the source clock in frequency to generate the internal CPU clock, or bypasses the PLL to become the internal CPU clock. To use the PLL to generate the CPU clock, the external PLL filter circuit must be properly designed. Table 3, Table 4, and Figure 5 show the external PLL circuitry for either x1 (PLL bypass) or x4 PLL multiply modes. Table 3 and Figure 6 show the external PLL circuitry for a system with ONLY x1 (PLL bypass) mode. To minimize the clock jitter, a single clean power supply should power both the ’C67x device and the external clock oscillator circuit. Noise coupling into PLLF will directly impact PLL clock jitter. The minimum CLKIN rise and fall times should also be observed. For the input clock timing requirements, see the input and output clocks electricals section. Guidelines for EMI filter selection are as follows: maximum attenuation frequency = 20–30 MHz, maximum dB attenuation = 45–50 dB, and minimum dB attenuation above 30 MHz = 20 dB. Table 3. CLKOUT1 Frequency Ranges (1) (1) PLLFREQ3 (C13) PLLFREQ2 (G11) PLLFREQ1 (F11) CLKOUT1 FREQUENCY RANGE (MHz) 0 0 0 50-140 Due to overlap of frequency ranges when choosing the PLLFREQ, more than one frequency range can contain the CLKOUT1 frequency. Choose the lowest frequency range that includes the desired frequency. For example, for CLKOUT1 = 133 MHz, choose PLLFREQ value of 000b. PLLFREQ values other than 000b, 001b, and 010b are reserved.

For the best performance, TI recommends that all the PLL external components be on a single side of the board without jumpers, switches, or components other than the ones shown. (2) For reduced PLL jitter, maximize the spacing between switching signals and the PLL external components (R1, C1, C2, C3, C4, and the EMI filter).

However, systems should be designed to ensure that neither supply is powered up for extended periods of time if the other supply is below the proper operating voltage. System-Level Design Considerations System-level design considerations, such as bus contention, may require supply sequencing to be implemented. In this case, the core supply should be powered up at the same time as, or prior to (and powered down after), the I/O buffers. This is to ensure that the I/O buffers receive valid inputs from the core before the output buffers are powered up, thus, preventing bus contention with other chips on the board. Power-Supply Design Considerations For systems using the C6000™ DSP platform of devices, the core supply may be required to provide in excess of 2 A per DSP until the I/O supply is powered up. This extra current condition is a result of uninitialized logic within the DSP(s) and is corrected once the CPU sees an internal clock pulse. With the PLL enabled, as the I/O supply is powered on, a clock pulse is produced stopping the extra current draw from the supply. With the PLL disabled, an external clock pulse may be required to stop this extra current draw. A normal current state returns once the I/O power supply is turned on and the CPU sees a clock pulse. Decreasing the amount of time between the core supply power up and the I/O supply power up can minimize the effects of this current draw. A dual-power supply with simultaneous sequencing, such as available with TPS563xx controllers or PT69xx plugin power modules, can be used to eliminate the delay between core and I/O power up [see the Using the TPS56300 to Power DSPs application report (literature number SLVA088)]. A Schottky diode can also be used to tie the core rail to the I/O rail, effectively pulling up the I/O power supply to a level that can help initialize the logic within the DSP. Core and I/O supply voltage regulators should be located close to the DSP (or DSP array) to minimize inductance and resistance in the power delivery path. Additionally, when designing for high-performance applications utilizing the C6000™ platform of DSPs, the PC board should include separate power planes for core, I/O, and ground, all bypassed with high-quality low-ESL/ESR capacitors. 26 Submit Documentation Feedback Copyright © 2000–2013, Texas Instruments Incorporated Product Folder Links: SMJ320C6701-SP SMJ320C6701-SP www.ti.com SGUS030F – APRIL 2000 – REVISED SEPTEMBER 2013 Absolute Maximum Ratings (1) over operating free-air temperature range (unless otherwise noted) MIN MAX CVDD Supply voltage range (2) –0.3 2.3 V DVDD Supply voltage range (2) –0.3 4 V Input voltage range –0.3 4 V Output voltage range –0.3 4 V TC Operating case temperature range Tstg Storage temperature range (1) (2) S-suffix device –40 90 W-suffix device –55 115 –55 150 UNIT °C °C Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.

For example, when running parts at 140 MHz, use P = 7 ns. HCS enables HRDY, and HRDY is always low when HCS is high. The case where HRDY goes high when HCS falls indicates that HPI is busy completing a previous HPID write or READ with autoincrement. This parameter is used during an HPID read. At the beginning of the first half–word transfer on the falling edge of HSTROBE, the HPI sends the request to the DMA auxiliary channel, and HRDY remains high until the DMA auxiliary channel loads the requested data into HPID. This parameter is not tested. This parameter is used after the second half-word of an HPID write or autoincrement read. HRDY remains low if the access is not an HPID write or autoincrement read. Reading or writing to HPIC or HPIA does not affect the HRDY signal.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license 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 significant portions 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. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
