DSM2180F3V

These are system memory devices DSM2180F3V for use with Digital Signal Processors from the popular Analog Devices ADSP-218X family. DSM means Digital signal processor System Memory. A DSM device brings in-system programmable Flash memory, programmable logic, and additional I/O to DSP systems. The result is a simple and flexible twochip solution for DSP designs. DSM devices provide the flexibility of Flash memory and smart JTAG programming techniques for both manufacturing and the field. On-chip integrated memory decode logic and memory paging logic make DSM2180F3V easy to add large amounts of external Flash memory to the ADSP-218X family for bootloading upon power-up and/or overlay memory. The DSM2180F3V DSP accesses this Flash memory using either its Byte DMA (BDMA) interface or as external data overlay memory (no DMA setup overhead).
