... DSM2180F3 SUMMARY DESCRIPTION These are system memory devices 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 two- chip solution for DSP designs ...

... EMI levels, and power consumption. DSM memory and logic are “zero-power”, meaning they BUS I/O automatically go to standby between memory ac- cesses or logic input changes, producing low ac- tive and standby current consumption, which is ideal for battery powered products. DSM2180F3 5/63 ...

... A programmable security bit in the DSM protects its contents from unauthorized viewing and copy- ing. When set, the security bit will block access of programming devices (JTAG or others) to the DSM Flash memory and PLD configuration. The Table 1.
