DSM2190F4V
DSM (Digital Signal Processor System Memory)
For Analog Devices ADSP-2191 DSPs (3.3V Supply)
FEATURES SUMMARY
I
Glueless Connection to DSP
– Easily add memory, logic, and I/O to the Exter-
nal Port of ADSP-2191 DSP
I
Dual Flash Memories
– Two independent Flash memory arrays for stor-
ing 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 sec-
tors (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 exter-
nal 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
Up to 16 Multifunction I/O Pins
– Increase total DSP system I/O capability
– I/O controlled by DSP software or PLD logic
I
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 Express

In-System Programming (ISP) with JTAG
– Program entire chip in 10-25 seconds with no in-
volvement of the DSP
– Links with ADSP-2191 JTAG debug port
– Eliminate sockets for pre-programmed memory
and logic devices
– ISP allows efficient manufacturing and product
testing supporting Just-In-Time inventory
– Use low-cost FlashLINK
