DSM2180F3V Datasheet | STMicroelectronics

.. DSM (Digital Signal Processor System Memory) For Analog Devices ADSP-218X Family (3.3V Supply) Features SUMMARY s Glueless Connection to DSP - Easily add memory, logic, and I/O to DSP s Figure 1. Packages 128K Byte Flash Memory - For Bootloading and/or Data Overlay Memory - Programmable Decoding and Paging Logic allows accessing Flash memory as Byte DMA (BDMA) and as External Data Overlay memory - Rapidly access Flash memory with BDMA for booting and loading internal DSP Overlay memory. Alternatively access the same Flash memory as External Data Overlay memory to efficiently write Flash memory with code updates and data, a byte at a time with no DMA setup...
