ADSP-21369:  High-Performance 32-bit Floating-Point SHARC Processor for General Purpose Applications

Product Description

The third generation of SHARC® Processors offers increased performance, audio and application-focused peripherals, and new memory configurations. The ADSP-21369 increases performance to 400MHz while simplifying algorithm development with the integration of a high-bandwidth and very flexible external memory interface. The ADSP-21369 is based on a single-instruction, multiple-data (SIMD) core which supports both 32-bit fixed-point and 32-/40-bit floating point arithmetic formats and is completely code-compatible with all prior SHARC Processors allowing for maximum reuse of legacy code.

The ADSP-21369 increases the amount of on-chip memory to 2Mb SRAM and 6Mb ROM while integrating a variety of audio-specific and general purpose peripherals. Peripherals such as an all digital S/PDIF transmitter/receiver, 8-channel asynchronous sample rate converter, 8 high-speed serial ports, 4 precision clock generators, and multiple serial interfaces combine to ensure the ADSP-21369 maximizes system throughput while minimizing system bill of materials costs.

Features

  • 400MHz SIMD SHARC Core, capable of 2.4 GFLOPS peak performance
  • 2Mbits SRAM; 6 Mbits customer-definable ROM
  • High bandwidth, 32-bit external memory interface supporting glue-less interface to SDRAM, SRAM, and FLASH
  • Digital Audio Interface (DAI) enabling user-definable access to system peripherals including 8 serial ports (SPORTs), S/PDIF Tx/Rx, 8-channel asynchronous sample rate converter, and 4 precision clock generators.
  • Digital Peripheral Interface (DPI) enabling user-definable access to system peripherals including 2 SPI-compatible ports, 2 UARTs, 3 full-featured timers, and a two-wire interface compliant to the I2C standard.
  • 34 zero-overhead DMA channels
  • 16 Pulse Width Modulation (PWM) channels
  • 208-lead MQFPand 256-ball SBGA packages
  • Commercial and industrial temperature ranges
  • Maximum core performance is reduced for LQFP package

Model
The model number is a specific version of a generic that can be purchased or sampled.

Status
Status indicates the current lifecycle of the product. This can be one of 4 stages:
  • Pre-Release: The model has not been released to general production, but samples may be available.
  • Production: The model is currently being produced, and generally available for purchase and sampling.
  • Last Time Buy: The model has been scheduled for obsolescence, but may still be purchased for a limited time.
  • Obsolete: The specific part is obsolete and no longer available. Other models listed in the table may still be available (if they have a status that is not obsolete).
Package Description
