ADSP-21161N GENERAL DESCRIPTION The ADSP-21161N SHARC® DSP is a low cost derivative of the ADSP-21160 featuring Analog Devices Super Harvard Architecture. Easing portability, the ADSP-21161N is source code compatible with the ADSP-21160 and with first generation ADSP-2106x SHARC processors in SISD (Single-Instruction, Single-Data) mode. Like other SHARC DSPs, the ADSP21161N is a 32-bit processor that is optimized for high performance DSP applications.
ADSP-21161N When using the DAGs to transfer data in SIMD mode, two data values are transferred with each access of memory or the register file. Data Register File A general-purpose data register file is contained in each processing element. The register files transfer data between the computation units and the data buses, and store intermediate results.
ADSP-21161N Instruction Cache The ADSP-21161N includes an on-chip instruction cache that enables three-bus operation for fetching an instruction and four data values. The cache is selective—only the instructions whose fetches conflict with PM bus data accesses are cached. This cache enables full-speed execution of core, looped operations such as digital filter multiply-accumulates, and FFT butterfly processing.

ADSP-21161N (for example 10k ohm). These pins must be driven low with a strong enough drive strength (10–50 ohms) to overcome the SHARC keeper latches present on these pins. If the drive strength provided is not strong enough, data access failures can occur. For single processor SHARC systems using this host access feature, address pins ADDR17, ADDR18, ADDR19, and ADDR20 may be tied low (for example through a 10k ohm resistor), driven low by a buffer/driver, or left floating.
ADSP-21161N Core Embedded Studio or VisualDSP++ installed (sold separately), engineers can develop software for supported EZKITs or any custom system utilizing supported Analog Devices processors. Software Add-Ins for CrossCore Embedded Studio Analog Devices offers software add-ins which seamlessly integrate with CrossCore Embedded Studio to extend its capabilities and reduce development time.
ADSP-21161N PIN FUNCTION DESCRIPTIONS ADSP-21161N pin definitions are listed below. Inputs identified as synchronous (S) must meet timing requirements with respect to CLKIN (or with respect to TCK for TMS, TDI). Inputs identified as asynchronous (A) can be asserted asynchronously to CLKIN (or to TCK for TRST).

ADSP-21161N PACKAGE INFORMATION ESD CAUTION The information presented in Figure 7 provides details about how to read the package brand and relate it to specific product features. ESD (electrostatic discharge) sensitive device. Charged devices and circuit boards can discharge without detection.

ADSP-21161N protection circuitry. With this technique, if the 1.8 V rail rises ahead of the 3.3 V rail, the Schottky diode pulls the 3.3 V rail along with the 1.8 V rail. Power-Up Sequencing — Silicon Revision 1.2 and Greater The timing requirements for DSP startup are given in Table 10. During the power-up sequence of the DSP, differences in the ramp-up rates and activation time between the two supplies can cause current to flow in the I/O ESD protection circuitry.
ADSP-21161N Clock Input In systems that use multiprocessing or SBSRAM, CLKDBL cannot be enabled nor can the systems use an external crystal as the CLKIN source. Do not use CLKOUT as the clock source for the SBSRAM device. Using an external crystal in conjunction with CLKDBL to generate a CLKOUT frequency is not supported. Negative hold times can result from the potential skew between CLKIN and CLKOUT. Table 11.
ADSP-21161N Clock Signals The ADSP-21161N can use an external clock or a crystal. See CLKIN pin description. The programmer can configure the ADSP-21161N to use its internal clock generator by connecting CLKIN the necessary components to CLKIN and XTAL. Figure 12 shows the component connections used for a crystal operating in fundamental mode.

ADSP-21161N Synchronous Read/Write — Bus Master Use these specifications for interfacing to external memory systems that require CLKIN, relative to timing or for accessing a slave ADSP-21161N (in multiprocessor memory space). When accessing a slave ADSP-21161N, these switching characteristics must meet the slave's timing requirements for synchronous read/writes (see Synchronous Read/Write — Bus Slave on Page 32).
ADSP-21161N Synchronous Read/Write — Bus Slave Use these specifications for ADSP-21161N bus master accesses of a slave’s IOP registers in multiprocessor memory space. The bus master must meet these (bus slave) timing requirements. Table 19.

ADSP-21161N Asynchronous Read/Write — Host to ADSP-21161N Use these specifications for asynchronous host processor accesses of an ADSP-21161N, after the host has asserted CS and HBR (low). After HBG is returned by the ADSP-21161N, the host can drive the RD and WR pins to access the ADSP-21161N’s IOP registers. HBR and HBG are assumed low for this timing.

ADSP-21161N During reset, the DSP will not respond to SBTS, HBR, and MMS accesses. Although the DSP will recognize HBR asserted before reset, a HBG will not be returned by the DSP until after reset is deasserted and the DSP completes bus synchronization. Three-State Timing — Bus Master, Bus Slave These specifications show how the memory interface is disabled (stops driving) or enabled (resumes driving) relative to CLKIN and the SBTS pin.

ADSP-21161N DMA Handshake These specifications describe the three DMA handshake modes. In all three modes DMAR is used to initiate transfers. For handshake mode, DMAG controls the latching or enabling of data externally. For external handshake mode, the data transfer is controlled by the ADDR23–0, RD, WR, MS3–0, ACK, and DMAG signals. For Paced Master mode, the data transfer is controlled by ADDR23–0, RD, WR, MS3–0, and ACK (not DMAG).

ADSP-21161N tions made directly from speed specifications will result in unrealistically small skew times because they include multiple tester guardbands. The setup and hold skew times shown below are calculated to include only one tester guardband. Link Ports Calculation of link receiver data setup and hold relative to link clock is required to determine the maximum allowable skew that can be introduced in the transmission path between LDATA and LCLK.
