DSM2190F4V
DSM (Digital Signal Processor System Memory) For Analog Devices ADSP-2191 DSPs (3.3V Supply)
FEATURES SUMMARY s Glueless Connection to DSP Easily add memory, logic, and I/O to the External Port of ADSP-2191 DSP s Dual Flash Memories Two independent Flash memory arrays for storing DSP code and data. DSP may access the two arrays concurrently (read from one while erasing or writing the other) 256K x 8 Main Flash memory divided into 8 sectors (32KByte each) Ample storage for booting DSP code/data upon reset and subsequent code swaps Large capacity for data recording 32K x 8 Secondary Flash memory divided into 4 sectors (8 KByte each). Multiple uses: Small sector size ideal for small data sets, and calibration or configuration constants Store custom start-up code in one or more sectors and configure DSP to run from external memory upon reset (no boot) Concatenate Secondary Flash with Main Flash for total of 288 KBytes Each Flash sector can be write protected. Built-in programmable address decoding logic allows mapping individual Flash sectors to any address boundary s Up to 16 Mult
ifunction I/O Pins Increase total DSP system I/O capability I/O controlled by DSP software or PLD logic s General purpose PLD Over 3,000 Gates of PLD with 16 macro cells Use for peripheral glue logic to keypads, control panel, displays, LCDs, and other devices Eliminate PLDs and external logic devices Create state machines, chip selects, simple shifters and counters, clock dividers, delays Simple PSDsoft ExpressTM software...Free s Operating Range VCC: 3.3V 10%; Temperature: 40oC to +85oC
