ADSP-21489KSWZ-4B Typical application Circuitry

The ADSP-21489KSWZ-4B, from Analog Devices' SHARC series, is a 32-bit floating-point processor optimized for high performance audio and industrial signal processing applications. Using the ADSP-21489KSWZ-4B, the following application circuit is described in basic terms:

1. Power Supply: The ADSP-21489KSWZ-4B operates from a dual-supply voltage system - a 1.2V core voltage (VDD_INT) and a 3.3V I/O voltage (VDD_EXT). It's recommended to place decoupling capacitors near these power pins to ensure signal integrity.
2. Clock Signal: An external clock signal must be supplied to its CLKIN pin. This can come from an external oscillator or a clock signal from another part of your system.
3. Reset Circuit: A reset signal is required to manage the reset functionality of the DSP. The RESET pin is active low, and the timing should be matched with the specifications of your system.
4. Boot Configuration: The state of BOOT_CFG pins during the reset process determines the source from which the processor will boot. This provides flexibility in your system design.
5. Memory Interface: The ADSP-21489KSWZ-4B has on-chip memory, but it also supports connections to external memory devices like SDRAM, SRAM, and Flash Memory. Depending on your memory choice, the relevant memory interface pins need to be properly connected.
6. Peripherals: Depending on your specific application, you may need to connect and configure the integrated peripherals like SPI, UART, and I2C.
7. Debugging/Emulation: For debugging and emulation purposes, a JTAG interface and a serial port (DSP) are provided.
8. Grounding: The grounding scheme should follow best practices. Ground connections should be made via the AGND (analog ground) and DGND (digital ground) pins to the system ground.
This is a fundamental instruction for assembling a circuit using the ADSP-21489KSWZ-4B. Depending on the exact requirements of your system, your implementation can be different. Always refer to the device datasheet and hardware reference manual for comprehensive information and guidance.
