DSM2150F5V
DSM (Digital Signal Processor System Memory) for Analog Devices DSPs (3.3V Supply)
FEATURES SUMMARY
s

Glueless Connection to DSP Easily add memory, logic, and I/O to the External Port of ADSP-218x, 219x, 2106x, 2116x, 2153x, and TS101 families of DSPs from Analog Devices, Inc. Dual Flash Memories Two independent Flash memory arrays for storing DSP code and data Capable of read-while-write concurrent Flash memory operation Device can be configured as 8-bit or 16-bit Built-in programmable address decoding logic allows mapping individual sectors of each Flash array to any address boundary Each Flash sector can be write protected 512 KByte Main Flash memory Ample storage for boot loading DSP code/ data upon reset and subsequent code swaps Large capacity for storing tables and constants or for data recording 32 KByte Secondary Flash memory Smaller sector size ideal for storing calibration and configuration constants. Eliminate external serial EEPROM. Optionally bypass internal DSP boot ROM during start-up and execute code directly from Secondary Flash. Use for custom start-up code and In-Appli
cation Programming (IAP). Up to 40 Multifunction I/O Pins Increase total DSP system I/O capability I/O controlled by DSP software or PLD logic General purpose PLD Use for peripheral glue logic to keypads, control panel, displays, LCDs, and other devices Over 3,000 gates of PLD with 16 macro cells Eliminate PLDs and external logic devices Create state machines, chip selects, simple shifters and counters, clock dividers, delays Simple PSDsoft ExpressTM development software, free from www.st.com/psm
